Zhongde CNC Machining Process

Zhongde offers a wide range of custom CNC machining services including CNC milling and CNC turning. CNC machining is a subtractive manufacturing process to make custom-machined parts. The CNC machine removes parts of the workpiece by machining operations such as turning, drilling, or milling, according to codes (g-code and m-code) obtained from the CAD model and containing instructions on machining parameters.

The general plastic CNC machining materials are listed below:

  • ABS
  • PP/Polypropylene
  • Nylon6
  • POM/Delrin
  • PVC
  • LDPE
  • HDPE
  • PC/Polycarlonate
  • PTFE

The general metal CNC machining materials are listed below:

  • Aluminum
  • Copper
  • Stainless
  • Brass Steel
  • Carbon Steel
  • Steel Alloy

Advantages of Custom CNC Machining


Small Production Run

CNC machines can manufacture one or multiple samples from the same design, opening the door to batch-process manufacturing.


Quick Turnaround Times

With advanced CNC machines, the manufacturing speed of different types of high-quality CNC machining parts is accelerated.


Fully Automatic Production

Computers are used to control the machines, the process is automated therefore increasing speed and quality of manufacturing.


Easy to Process Large Size Part

CNC machines create outputs that cannot be reproduced by manual machines when used in tandem with advanced design software. The machines can produce a variety of sizes, textures and shapes.


High Precison Production with Small Tolerance

Zhongde, a reputable fast CNC molding and machining company with its own factory, shows greater dimensional accuracy. In terms of its tighter tolerance, even ±0.025mm tolerance can be achieved.

Types of CNC Operations

CNC machining services by Zhongde, a professional on-demand manufacturer in China, mainly include CNC milling for rough machining, CNC turning for rotating surfaces, CNC drilling for machining holes, CNC planing for straight-shaped surfaces, and grinding for cylindrical surfaces.
Types Description
CNC Milling Milling is mainly used for rough machining and semi-finish machining of various planes, various grooves, etc.
CNC Turning Turning is method of cutting the rotating surface of workpiece on a lathe with a turning tool.
CNC Drilling Drilling refers to the method used to machine holes. The drilling tool moves relative to the workpiece and feeds axially.
CNC Planing Planning is a method of cutting on a planing machine using a planer and is mainly used to process straight-shaped surfaces.
CNC Grinding Grinding is mainly used for finishing the inner and other cylindrical surfaces, inner and outer conical surfaces, and planes, and forming surfaces of parts to obtain higher dimensional accuracy and smaller surface roughness

Applications of CNC Machining
