Precision Machining Explained: Key Tips & Best Practices for CNC Operations

    Precision machined components can be produced in precise computerized control and widely used in multiple important industries, what is precision machining and what should we pay attention to in precision CNC machining? Follow us CNCLathing.com to find some useful precision parts processing tips.

What is Precision Machining？

     Precision machining is a manufacturing process to remove materials from the workpiece to create precise tools and parts with close tolerance finishes, the precision parts machining process are executed with repeatability, stability, consistency, accuracy, and durability. The precision machining machines including turning, milling, electrical discharge machining, and more are generally controlled by digital signals from computers, the process can be called CNC precision machining, through which the positioning, velocity, coordination, feed rates, and more aspects can get particular control.

What materials can be processed in precision machining?

Precision machining and machined parts are available in a wide selection of materials.
– Metal: steel, stainless steel, bronze, copper, brass, aluminum, alloy, etc.
– Plastic: PC, PVC, POM, PP, PEEK, ABS, Nylon, PLA, PTFE, HDPE, etc.
Other materials: graphite, glass, wood, rubber, etc.

What Should Pay Attention to in Precision CNC Machining?

1. Accurate design drawings are required
Precision hardware processing is to machine some hardware parts with small diameters, the design drawings of the product should be accurate and detailed, each data of the part should be ensured and clear, because for precision parts machining, a miss is as good as a mile. If the drawings without accuracy, the machined parts probably can’t be used, thus increasing the production cost. Therefore, it is necessary to check and review the drawings before machining.

2. Materials selection for CNC precision machining
The products processed by precision CNC machining are generally used in industries and fields with high quality standards such as aviation, clocks, watches, electronics, military, semiconductor, etc., so the requirements for the processing materials are also very high, each part should be manufactured with superior quality materials. In addition, not all machinable materials can be used in the same condition, the product applications and materials mechanical properties should take priority into consideration.

3. Cost and budget
Precision CNC machining parts prices are determined by processing time, materials, operations and more factors, so you should take these into account when setting the budget and control the cost especially in large batch precision parts CNC machining. Improving production technology and efficiency plays an important role in controlling the cost.
