CNC Machining

Precision Milling & Machining

CNC Machining is short for computer numerical control machining. It is a machining technique that involves processing the parts on certain CNC machine. Other than conventional machining, CNC machining tools are controlled by precisely programmed computer system. The code used to program CNC units is generically called G-Code. It contains information of how to exactly perform the steps to make the desired parts. CNC machining G code can be manual programmed, but usually CNC machine is equipped with CAM (Computer Aided Manufacturing) software, which can read CAD (Computer Aided Design) files and generate G code program automatically.

CNC MachiningOther assist equipments include: Milling machine, Drilling machine, Centerless Grinding machine, External Cylindrical Grinding machine, etc.

Inspection equipment: Vernier Caliper, Micrometer, Height Gage, Hardness Tester, Two-dimensional image measuring instrument, TESA Micro-Hite 300, Mitutoyo surface Roughness Tester, Mitutoyo CMM and Ultrasonic Cleaner.

CNC machining is probably the most fast and cost-effective way to customize a part, that’s why it becomes the most often used rapid prototyping method. Although CNC fabrication is fast and convenient, but not all precision components that can be fabricated on CNC machines. For a workpiece that has very complicated structure, and with large quantity required, it is better to choose die casting as the manufacturing process if it is metals, or to choose injection molding if it is plastics. But if you don’t mind to have the part divided into several pieces, and gluing pieces together after fabrication to form the whole one, then CNC machining process is the choice. 

CNC machining service is often the first choice when you are in need of precision metal parts. With high speed CNC machine, most of the metals can be manufactured, including titanium. Parts that machined by CNC are in high specification, tight tolerance, good strength and smooth surface, and comes with variety of surface finishing treatment. But when it comes to part with complicated structure and large volume, then it needs to take other manufacturing methods into consideration, so as to choose the best one according to your needs. But CNC machining can be sub-manufacturing process to other methods.  If you don’t know which fabricating process best suits your case, don’t worry, our experienced engineers will suggest the right one for you based on the drawing, material, quantity and application you provide.

CNC Machining Services in China

CNC machining industry develops very quickly in China. Up untill now, there are hundreds of thousands of CNC machining manufacturer in China. One-quarter of machining factory in China is big company. They are either state-owned enterprise run by government or joint venture run by several shareholders. Those factory often covers an area of more than 10000 square meters, with hundreds of advanced equipment and skilled staff. They can do the most complicated and precision machining work. Of course, with much higher price than those small CNC machining shop in China. So if your parts need high requirements and high standards, you can find those companies work for you.

Medium scaled CNC machining factory take half of Chinese market share. They are normally with development over 10 years. They have the flexible capability to process most of the machining work, from ordinary to high precision parts, from prototype to volume production. Of course, the pricing is relatively higher than those with individual CNC machining shop. But the quality is which you can count on. This kind of machining factory is for most customers’ choice.

Small CNC machining shops run by personal maybe take one-third of the share. Those machining shop in China often runs by mechanics who had been worked as operator before. They takes machining jobs from other factories. This kind of job is often with small volume and low standards. Most of CNC machining shops don’t have quality control method. So the quality with them is a big issue. But if the operator is a skilled mechanics, then the job done by them is pretty.
