Most of the manufacturing companies are busy employing CNC or compute numerical control technology in their production processes for enhanced effect. The integration of CNC in a production unit is a great way to enhance the flexibility and performance of CAD or computer aided design and CAM (computer aided manufacturing) chain. Hence, there is also a greater effect on the competitive levels of such companies.
When compared, the hardware capacities of CNC systems have significantly improved in the last few decades. This is not all. The software elements have also been upgraded effectively in order to facilitate the enhancement seen on the latest line of CNC machines.
The passive approach adopted by most of the CNC manufacturers, these days has resulted in a lot of incompatibilities among varied CAM, CAD and CAM solutions available in the industry for the customers.
Hence, it is very important to opt for a machine coming from a CNC manufacturer that abide by all the industry standards and believe in providing the latest that’s available under the category of these machines.
Here are some of the considerations you need to keep in mind when deciding on a CNC manufacturer to purchase the best machine available for the job:
- Quality: The quality of a CNC machine is of utmost importance. Make sure that the CNC manufacturer put in all possible efforts to make sure that the machine is delivered to a client in impeccable condition. There should be a sure shot guarantee for quality. The CNC manufacturer needs to follow all the quality control regulations set by the industry and keeps up to national and global standards. You need to check out that the manufacturing materials are tested to perfection and exactly match industry standards. The process of manufacture must also take place under strict and expert supervision of experienced technicians. The finished products need to go through an analysis phase to detect any existing faults.
- Infrastructure: The infrastructure of a CNC making machines speaks volumes about the quality of the machine. The infrastructure should incorporate experienced technicians, many workers and finest of machinery. The warehouse of the CNC manufacturing company should be efficacious enough to store a huge amount of products according to the requirements of the clients.
- Clientele: The clientele a CNC manufacturer holds will also tell you a lot about the quality of machine he sells to the customers. You must ask for some of their existing and valued clients. If possible, you need to ask for some references. This will provide you an idea of people’s review about the CNC machines.
Following and keeping mind all the tips mentioned above will let you find out a CNC manufacturer who provides the best and most efficient machines for your business.

Cnc Shop, Water Jet Cutting Machines, Granite Bridge Saw
CNC Machines technology is one of the new emerging technologies used in metal industry. The introduction of CNC (Computer Numerical Control) machines has made a great impact on the manufacturing industry. These are very useful as can help to cut curves as a straight line; Complex 3-D structure can be produce and thus reduced the human actions. This is one of the reasons so that CNC Shop are getting so popular and helpful. It gives more flexibility in holding the parts in manufacturing and to change the machine to produce different components.
CNC machine has the functions of milling, grinding, polishing and sculpting.
It is especially suitable for producing high grade basin board and other abnormal products
Made of stone, ceramic, glass and micro-crystal stone. The machine will automatically
finish the processing of any required profile by simple setting. The products are of high precision and good glossiness rate.
One more example of same type of tool is Water jet cutting Machines, which are capable of slicing into metal or materials with high velocity and pressure. It is often used for both fabrication and manufacture of parts for machinery and some other devices.
Water jets can be used to cut materials as diverse as fish sticks, 'gas station' sandwiches, and titanium. But still there are some materials that cannot be effectively cut with a water jet cutter like, tempered glass, which shatters when cut, regardless of the cutting technology used.
Water jet cutting technology is the most efficient, cost effective and fastest growing method to cut materials. Due to its versatility and ease of operation, fabricators are quickly realizing the vast potential of these machines. Water jets (or abrasivejets) can cut virtually any material in any shape with no heat distortion or mechanical stress usually caused by other methods.
Granite Bridge Saw are also getting very useful for industrial uses. Bridge Saws also include different varieties for the different purposes in Small laboratories or industries as Marble and granite bridge cutter, diamond saw machine into rails, electronic bridge shape sawing machine, Compactness and sturdiness etc.
Marble Services Co. has contracted with many corporations, businesses and residents to perform hundreds of restoration and refinishing projects, both large and small. Following the Northridge Earthquake we restored many damaged marble statues and stonework, in many cases masking any evidence of damage.

Apple's Design Concepts
One of the most exciting design concepts Apple has recently introduced is the unibody. This is the enclosure for the MacBook Air, the 15 inch MacBook Pro, and the new MacBook.
The unibody begins life as a single piece of aluminium. Using CNC (computer numerical control) milling machines, Apple then creates a laptop casing that accommodates a keyboard, trackpad, ports, display, and the comprehensive interior electronics.
The result is robust and lightweight. The new aluminium MacBook weighs in at just 2.04 kg (4.5 pounds). This is modest for a laptop packed with so many features. It is still heavier, though, than the wonderfully thin MacBook Air’s 1.36 kg (3 pounds). These two laptops, together with the MacBook Pro, catch the eye with their engineering perfection and elegance.
The unibody is a simple concept but an extremely difficult idea to achieve in practice. This is why laptop manufacturers generally build their casings from separate parts. These allow room for error. The unibody, however, must be precise in every respect; if not, the interior components won’t fit.
This bold approach to design is typical of Apple. Another example is the iMac, Apple’s desktop computer that holds its technology behind the 20 inch and 24 inch widescreen displays. The iMac’s enclosure is a single sheet of aluminium, apart from a compartment on the bottom that gives access to the memory cards. The ports, iSight camera, microphone, optical drive slot, and inner parts are all discretely integrated. Together they provide a powerful computer that takes up far less space than any comparable PC.
The Mac mini is not as slim as the Apple laptops and the iMac, but it doesn’t need to be thin to be stylish. Instead, it’s a fine example of how a quality computer can reduce clutter by being just 16.5 cm (6.5 inches) square, and 5 cm (2 inches) high. The anodised aluminium enclosure, pearly white cover, curved corners, and quiet running make the Mac mini a desirable object to have sitting on a desk. It certainly compares well to the bulk of a standard desktop PC.
Apple’s iPods have a similar design philosophy. Aluminium, glass, and highly polished stainless steel feature alongside subtle curves and carefully positioned controls. The Click Wheel design of the classic and nano has even become a style icon in its own right, deriving from the Scroll Wheel and Touch Wheel of earlier generation iPods.
iPod design, like the laptops, is also about weight or, to be exact, the lack of it. The iPod nano is a mere 36.8 grams (1.3 ounces), although the iPod shuffle beats this with its feather-like body of 15.6 grams (0.55 ounce).
Ease of use
Exterior design alone, however, has not kept Apple’s products at the forefront of multimedia technology. The hidden designs and compatibility of the hardware and software within a Mac and iPod have also helped to achieve this.
This compatibility means that the user of an Apple product has an enjoyable and trouble-free experience. The design of Mac OS X, for instance, provides a fast and logical operating system that outshines Windows Vista in almost every respect.
Ease of use extends to the software that comes with every Mac such as the Safari web browser. Safari doesn’t just find information quickly on the Internet – it keeps up with the latest web technology, organises your data, and helps you distinguish one item from another.
Safari’s success as the world’s best web browser, and the popularity of other Apple software such as the iLife suite of applications, is partly due to frequent revisions. Apple’s software design specialists never wait for things to happen: they are always searching for ways to develop and improve. Mac users can therefore be confident that their software is up to date.
The same is true of the iPod designers. Recent design improvements include Genius, which automatically creates playlist of songs that match; the accelerometer, which makes games more fun to play and provides the iPod nano with its shake to shuffle feature; and the 3D graphics of the iPod touch.
The iPod touch, of course, has an outstanding Multi-Touch screen that is a major design feature by itself. Apple also uses the Multi-Touch concept on its laptops, and has now given the MacBook, MacBook Pro, and MacBook Air larger trackpads made of glass and with more features than previously. The result not only makes these laptops more fun to use – they look sleeker as well.
Concern for the environment
The third element of Apple’s approach to design is concern for the environment. The LED backlighting for displays doesn’t contain mercury; internal cables don’t have PVC; and components are free of toxic BFRs (brominated flame retardants).
Apple also promotes the recyclable qualities of the aluminium and arsenic-free glass that make up many of the Mac and iPod casings, and has cut back on the packaging it uses.
Such efforts are considerable, and are developing all the time. Among the acknowledgements are the granting of Energy Star status for Macs, thanks to their excellent energy efficiency, and much-coveted EPEAT (electronic products environmental assessment tool) gold ratings for the MacBook Pro and MacBook Air.
These successes prove that environmental concerns can play a major role in design concepts. No doubt other companies will follow Apple’s lead.
Innovation
Innovation has not featured here as a design concept because it is a separate principle. With Apple, innovation is fundamental to the company’s existence and strategy. Some manufacturers view innovation as an end in itself, but Apple treats it as part and parcel of everyday design and development.
Customers can therefore take innovation for granted. It underwrites products that are great to look at, straightforward to use, and that respect the environment. In other words, they’re brilliant designs.

Aluminium Die Casting
Aluminium is the preference metal for making light weight parts of vehicles, aerospace, transport and many more industries. Casting of liquid aluminium alloys into metal moulds utilizing systems like gravity, low pressure and high pressure die casting is an economical way of making difficult shapes which need minimum machining.
The main die casting alloys are: zinc, aluminium, magnesium, copper, lead, and tin etc. Main advantages of aluminium die casting are:
• Lightweight
• Dimensional stability for complex shapes and thin walls
• High thermal and electrical conductivity
• It retains strength at high temperature
CNC Machines technology is one of the new emerging technologies used in metal industry. The introduction of Computer Numerical Control (CNC) machines has made a good impact on the manufacturing industries. These are very useful as can help to cut curves as a straight line; Complex 3-D structure can be produce and thus reduced the human actions. It gives more flexibility in holding the parts in manufacturing and to change the machine to produce different components.
With CNC Precision machining, all of this drilling can be done automatically instead of the manual process listed above. Machining has to be precise, and whether you use a CNC lathe or milling machine, you have to make sure the part is right. The computer takes a lot of the guesswork out of the machining of these parts. In fact, a CNC programmer can sometimes get bored watching the machine do all the work.
There are number of industries providing World class quality, manufacturing and services in Aluminum die casting and CNC Precision Machining.

Computer Aided Manufacturing Applications
Computer Aided Manufacturing (CAM) refers to an automation process, which accurately converts product design and drawing or the object into a code format, readable by the machine to manufacture the product. Computer aided manufacturing complements the computer aided design (CAD) systems to offer a wide range of applications in different manufacturing fields. CAM evolved from the technology utilized in the Computer Numerical Control (CNC) machines that were used in the early 1950s. CNC involved the use of coded instructions on a punched paper tape and could control single manufacturing functions. CAM controlled computer systems, however, can control a whole set of manufacturing functions simultaneously.
CAM allows work instructions and procedures to be communicated directly to the manufacturing machines. A CAM system controls manufacturing operations performed by robotic milling machines, lathes, welding machines and other industrial tools. It moves the raw material to different machines within the system by allowing systematic completion of each step. Finished products can also be moved within the system to complete other manufacturing operations such as packaging, synthesizing and making final checks and changes.
Some of the major applications of the CAM system are glass working, woodturning, metalworking and spinning, and graphical optimization of the entire manufacturing procedure. Production of the solids of rotation, plane surfaces, and screw threads is done by applying CAM systems.
A CAM system allows the manufacturing of three-dimensional solids, using ornamental lathes with greater intricacy and detail. Products such as candlestick holders, table legs, bowls, baseball bats, crankshafts, and camshafts can be manufactured using the CAM system. CAM system can also be applied to the process of diamond turning to manufacture diamond tipped cutting materials. Aspheric optical elements made from glass, crystals, and other metals can also be produced using CAM systems.
Computer aided manufacturing can be applied to the fields of mechanical, electrical, industrial and aerospace engineering. Applications such as thermodynamics, fluid dynamics, solid mechanics, and kinematics can be controlled using CAM systems. Other applications such as electromagnetism, ergonomics, aerodynamics, and propulsion and material science may also use computer aided manufacturing.

CNC Milling Machine Buying Tips
CNC stand for Computer Numerical Control, and refers specifically to the computer control of machine tools. The main purpose of CNC Milling Machines is to repeatedly manufacture complex parts in metal as well as other materials, using a specially coded program. This specially coded program that is used by CNC Milling machines is written in a notation called G-code. G-codes represent specific CNC Milling functions in alphanumeric format. CNC Milling was developed in the late 1940's and early 1950's by the MIT Servomechanism Laboratory.
1. About CNC
- Computer Numerical Control (CNC) Milling is the most common form of CNC - CNC mills can perform the functions of drilling and often turning - CNC Milling machines are classified according to the number of axes that they possess - Axes are labeled as x and y for horizontal movement, and z for vertical movement - The evolution of CNC milling machines drastically changed the manufacturing industry - Curves are as easy to cut as straight lines, complex 3-D structures are relatively easy to produce, and the number of machining steps that required human action is way down.
2. The Fabrication Process
With the use of CNC milling machine the fabrication process of the materials have been trimmed down to just a couple of steps. CNC Milling machines now days are driven directly from computer softwares crated by CAD software packages. With the use CNC Milling machines the assembly of parts can go from brief designs without any intermediate paper drawing works being required. In one sense, with the use of CNC milling machines industrials tasks are done must easier and much faster and the production cost of the company is also lessening out. CNC machines may be said to represent special industrial robot systems, as they are programmable to perform any kind of machining operation, within certain physical limits, like other robotic systems.
3. Buying Tips
Before buying a CNC milling machine it is a must that you should have knowledge about the CNC milling machines basic parts. A CNC milling machine is basically composed of a Safety shield that is usually a clear plastic cover that cover and protects the cutting area. The Tool bit, this part of the CNC milling machines is the one that do the cutting. Spindle Shaft, is the part that holds the tool bit. Spindle Motor, is the part of the CNC milling machine that drives the cutter. The Vertical Column, the part that holds the spindle and all of its part. The Cross Side, a moveable support where the work piece is being cut. The axis motors, which moves the cross side into different axis and the Controller box.
When purchasing your milling machine make sure to check that you have all of this part intact on your CNC milling machine, for if one of this parts is not there it will not surely work or will produce an undesirable end product. Also see to it to check out for safety features, never buy a CNC milling machine without an emergency stop button, this button automatically stops machining when it is pressed. Human, hardware or software errors could mean big losses if the CNC cannot be stopped quickly enough to correct the problem. Also check out the control panel part, it is advisable to buy one with a big control guide sticker so you can clearly see it.
Also check out the screws and tools with long overhangs and adapters, be more observant about cracks and breaks on this CNC milling tools. Make sure that the plastic shield that you are purchasing with your CNC milling machine is made up of high impact polycarbonate plastic. An insert break loose from a 35 mm diameter CNC milling cutter at a spindle speed of 45,000 rpm will be thrown out at a speed of 90 meters per second - equivalent to a bullet that is being shot out of a pistol!

Cycle Time Reduction Principles for CNC Machining Equipment
Cycle time is defined to be the time that happens from the time a task or series of tasks is initiated to the time a task is completed. Example, the cycle time is the time a shipping order is printed to the time it is loaded on the truck and the system is updated. An alternate definition would be is the time it takes to load, run, and unload on workpiece.
Cycle time of a machine can be simply measured by timing how long it takes from pressing the button to start the cycle for the first workpiece to the pressing the next button for the next workpiece.
Production quantities in an industry dictate that the more workpieces you run, the more important it is to achieve the goal of lowering the cycle time.
Everything and anything that happens in a Computer Numerical Control (CNC) machining equipment can be divided into four categories:
1.) On-line, productive tasks:
These are the actual machining operations that occur during a CNC cycle. These are the milling, drilling, tapping, reaming, and any other machining operation that in some way furthers the completion of the workpiece. To minimize the cycle time in these areas, there are two ways in which this can be achieved. One would be through careful process planning.
The process engineer must select an appropriate machine tool, cutting tools, fixturing, and machining order in a way that it matches the number of workpieces to be machined that will be based on the production quantity. The cycle time will be a reflection of the processes being used to machine workpieces.
If in the many times that your company’s processes have already been developed and implemented before you begin your cycle time reduction program, then your second alternative is to optimize cutting operations for this would involve properly selecting cutting tool materials, feeds, and speeds to machine workpieces as efficiently as possible with the current process.
2.) On-line, non-productive tasks:
These are tasks that occur during the machining cycle that do not actually further the completion of the workpiece. The first thing Computer Numerical Control people often target for improvement is wasted program execution time. These are the things like rapid movements, tool changes, M-code execution and spindle acceleration/deceleration. Reducing program execution time in this area is usually easy.
It often takes nothing more than carefully monitoring the production run for a few workpieces to find those times when the program can be modified to eliminate noticeable pauses during the cycle. Although keep in mind that the worker for these machines must not overlook other processes for they may be so concerned with minimizing program execution that they overlook other operations, resulting in severe wastes of cycle time.
3.) Off-line, non-productive tasks:
These are the tasks performed in the machining cycle that do nothing to further the completion of the workpiece. Since these types of tasks are done while the machine is producing workpieces, they do not actually add to the cycle time. It is possible to free the operator of the machines of performing off-line productive tasks if they have little, or nothing to do during lengthy machine cycles.
4.) Off-line, productive tasks:
These are the tasks done away by the CNC machine, while the machine is producing workpieces, which would further the completion of the workpiece. This is extremely helpful during lengthy CNC cycles, tasks in this category can reduce the time it takes to complete the production run dramatically, which would effectively reduce cycle time.
