Precision CNC Machining: The Contemporary Face of the Manufacturing Industry: Precision CNC machining is a novel manufacturing process that gives extremely accurate and repeatable results and is used in CNC machining industries for products that require extremely low tolerances, which are sometimes even in microns. Computer Numeric Control (CNC) is an innovative manufacturing process that replaces human feedback with precise computer programs. This technology has been around for a little while but recently significant developments have been made at a rapid pace. A CNC machine has the capability of performing all the actions that a traditional machine can perform, but in this case, the computer guides the cutting tool with extreme precision instead of the human operator. In this process, a CAD model is interpreted by the computer using any available CAM software, and the instructions are generated in a set of codes that control the workings of the machine. Precision CNC machining is a novel manufacturing process that gives extremely accurate and repeatable results and is used in CNC machining industries for products that require extremely low tolerances, which are sometimes even in microns.

Usages of Precision CNC Machining in some Advanced Countries

It is also a very obvious situation that the trend to use a same machine to finish procedures of milling, cutting, grinding is more and more fierce now. In order to machine the précised electro-optical mechanical parts that apply on aerospace industry and space navigation industry, for example the reflector on telescope, it will need to build very precise machining equipment, also those mechanical parts are including the microelectronic machines, micro sensors, micro motivators and so on.

The advanced countries which do more works for the precision machining are European and American countries and Japan, but they focus on different fields.

European and American countries spend a lot of energy in the development of energy and space, especially America, they spend a great amount of expenditure to the investigation of large UV reflector on telescope through X-Ray detecting, such as NASA.

Japan starts later than these European countries or America, but it is the fastest developing country in this area. The application of Japanese precious machining are civil products such automation equipment, gauges, CMM, mechanical devices, etc.

As for China, after several decades’ hard work on this, we are now more completely by importing advanced equipment and technology, for example the precision CNC machining equipment, CMM machine, tools, programming preparing.

Promoting Factors for Precision Machining Development

Even though time’s keeping moving, the technologies of precise machining are keeping updating, and precision tolerance of machining keeps improving. The investigation points among different countries are not the same, but the promoting factors to the development of precision machining are the same. Followings are the main factors.

  1. Pursue of High Quality Products

In order to make the magnetic disk has higher storage density, or lens has better optical performance, it will need to get a less rougher surface;

So as to sustain the normal function of electronic components, it will need to sustain no affected layers left on the parts surface after machining;

In order to maintain the best fitting performance for precision machines, it will need to ensure every tolerance on holes are the perfectness.

With cylinder surface requires surface roughness Ra<0.05mm, we have to use CNC grinding, then check with roughness instrument, then grinding, then check again until it meets the spec;

Automotive optic parts also have high precision demand for optic details or assembly surface, this normally not able to do any hand working on it.

In this case, a precision CNC 5 axis machine will be fitted a small tool of radius 0.125mm to run 30-50 hours on the optic details.

  1. Pursue to Smaller Precise Products

With the applying of precision machining, more and more engineering mechanical parts are becoming smaller and smaller, from 1989 to 2001, weight from computer from 6.2kg to 1.8kg. Now in 2018, we have portable tablets weight only 0.5kg, thickness is less and less, designers tend to create inner support parts with thickness even less than 0.3mm, even CNC machine can only machine details more than 0.4mm, how can a plate of 0.3mm thickness to machine successfully? The answer is yes, besides of CNC machining, we still have EDM, wire cut to fulfill this.

  1. Desire for High Quality Products

For bearings they will need on one hand to withstand heavy weight, on the other hand to keep turning, for these parts to improve their surface roughness can help to increase the anti-abrasion performance to lengthen the working stability and working life, material normally will adopt the Si3N4. The surface of the ceramic ball is highly to ask for nanometer, medical devices parts’ tolerance even needs to do +/-0.01mm, some metal investigating assembly parts such as endoscope is even required +/-0.001!

  1. Pursue the High Performance Products 

The improvement of high precision CNC tolerance is helping to decrease mechanical properties, noises and waves, good surface roughness can help decrease leakage of high sealing machines to cost down the damage, also, the adoption of Titanium, ceramic which can sustain high temperature also play new roles for the investigation of precision machining.

Serving a high-volume, high-precision market properly such as automotive prototype parts, flexible and reliable equipment is important, to not deliver or deliver poor quality is not a plan. Our dedication to this precision CNC machining equipment has supported us in adapting to the changes in parts’ complexities, tolerance requirements and delivery times, this is what we need to sustain and will always keep going to develop, no matter what challenges come into our way, Wayken is well-prepared to deliver parts quicker, better and at a lower cost than the competitors.

Concluding Remarks

As technology is advancing at an exponential rate, it is an undeniable fact that the demand for sensitive tools will increase as well. We can even see that today on a global level. Countries with strong manufacturing industry are striving towards creating a more favourable environment for Computer Numeric Control (CNC) and other related precision based technologies.For example, China, the largest manufacturing country today spends a significant amount of its industrial budget on the research about CNC technology and the amount is expected to grow in the coming years.
