What is CNC Machining?

CNC machining is a process in which engineers write programs, and then control CNC machine tools through computers to process materials.

Most of the products will be produced in small batches by CNC machining because CNC machining is more flexible in terms of quantity and material. We have 3/4/5 axis machines that meet customers’ requirements for customized products.

Whether it is metal or plastic, CNC machining can achieve +/-0.01mm, and the surface finish can reach Ra 0.4, which can meet various surface treatments.

CNC machining is a manufacturing process suitable for a wide range of industries, including automotive, aerospace, medical device, robotics, construction monitoring equipment, and agriculture equipment, and able to produce a range of products, such as frames, custom equipment, engines, gears, and tools.

Advantage of CNC Machining

1. Reduced Labor Costs;

CNC machining is hugely controlled by a software program and requires very little human interaction apart from the initial setup and data feeding. CNC machining also demands less advanced training, further reducing labor costs. With computers playing a major role, the chances of human error and compromised workplace safety are also reduced by a high percentage.

 

2. Flexible Production Quantity;

CNC Machines are built to provide maximum accuracy whether they are tasked to produce one metal machined part or thousands of machined parts.

 

3. Tight Tolerance

Can be 0.005 TO 0.01 mm

4. Ability to Produce Complex Parts

5. Works for a wide range of Material Type

Process of CNC Machining

CNC Milling

3-axis CNC milling, 4 axis CNC milling, 5 axes CNC milling, Manual Milling

The workpiece is held stationary directly on the machine bed or in a vice.

Material is removed from the workpiece using cutting tools or drills that rotate at high speed.

The tools are attached to a spindle, which can move along three linear axes.

 

 

CNC Turning

The workpiece is held on the spindle while rotating at high speed.

A cutting tool or center drill traces the outer or inner perimeter of the part, forming the geometry.

The tool does not rotate and moves along polar directions.
