What is Precision CNC Machining?

What is Precision CNC Machining?

Precision CNC machining is a metal working process that is based on computer-controlled machine tools. It is used for high precision machining of parts with difficult geometries, such as those found in the aerospace and medical industries.

The Precision CNC Machining (PCM) process is a subtractive manufacturing process that uses a cutting tool to remove material from the workpiece by means of high-speed cutting motions. It can be done manually or automatically with the use of computers and machine tools. It can be used to produce complicated 3D shapes such as those needed for aircraft engine components.

How precise is CNC machining?

Precision tolerance is the level of acceptable deviation from perfection. How much precision tolerance should be used depends on many factors such as the desired accuracy and the cost of production.

The tolerances for CNC machining are usually measured in thousandths of an inch, usually 4 decimal places (0.0004 inch – 0.0016 inch). Precision tolerances for CNC machining can be found in various standards and specifications such as ISO and ANSI/ASME, which also provide guidance on what to use for different applications.

How to find the best CNC Machining Service for Your precision machined parts needs

How to find the best CNC Machining Service for Your precision machined parts needs?

CNC machining is the process of generating parts with the help of computer-controlled cutting tools. This process relies on Computer Numerical Control (CNC) which is a numerical control technology that uses commands to specify the desired tool path for machining.

There are many CNC manufacturers around the world who offer precision machining services to their clients. But finding the best service for your needs can be tough.

To make it easier for you, here are some things you must keep in mind before selecting a CNC manufacturer:

  1. -What type of machine do you need?
  2. -What is your budget?
  3. -Do you want a CNC milling machine for metal, a lathe for wood or a router for plastics?
  4. -Do you have drawings of the part that needs to be manufactured?
  5. -Do you have a 3D model of the part that needs to be manufactured?
  6. -Where will the CNC machining take place – in our in our factory or in your plant?

Above points to keep in mind when searching for the best cnc machining service in China.
