Demand and advantage of small batch CNC machining

Product  application: For example, research projects, and gifts 

Low-volume production:  products do not need to be manufactured in large volumes by using mold manufacturing. In this way,  CNC batch machining can be used, which can save time and also can save money.

The market demand for goods is unclear: for example, the developed products don't have a predictable market demand.

Product is in early stages: if a product has just been designed, it needs to go through a couple rounds for design. 

Cost constraints: Some individuals and companies due to higher risk are not able to invest significant capital for high-volume manufacuring. So they chose batch CNC machining at early stages to save the cost.

Part manufacturing constraints: parts may have a specific shape that makes them harder or impossible to produce by using other technologies. So the engineer chooses to use CNC batch machining.

CNC machining: raw materials are directly machined to meet the requirements of the designed part. CNC machining speed is fast, part surface quality is excellent. By finishing the surface using methods such as silk screening and electroplating, parts look even more premium than those produced by the injection molding process. CNC technology is used in a wide range of materials cosisting both metals and plastics. 

The CNC machined parts have high quality and high-density. The CNC machines can address high-volume production demands. Once the CNC machine is programmed, the program can be used to machine thousands of identical shapes with tight tolerances.


Advantages of CNC processing:

  • Material cost is low, and the material selection range is wide
  • The machine and equipment are stable and easy to operate.
  • Parts can be appropriately decomposed
  • It can be easily adapted to parts with large size and simple structure.

Typical materials for CNC machining include 

Plastics:

ABS, PC, POM, PP, PMMA, Nylon, and Bakelite

Metals: 

Aluminum Alloy, Zinc Alloy, Low Carbon Steel, Copper, Stainless Steel. Besides, Teflon, PBT, PPS, PEET, and Polyurethane foam can also be used as processing material.
