Our advanced machining capabilities ensure exceptional quality for aerospace, medical, automotive, and electronics applications.

What is CNC turning?

CNC turning (Computer Numerical Control) involves placing a workpiece on a lathe and rotating it at high speed. Computer-controlled machining tools remove material to achieve the desired shape. CNC machines can control the workpiece's rotation and the movement of the cutting tool at varying speeds, enabling high-precision and efficient machining.

This technology is widely used in the manufacture of various metal and plastic parts, particularly in industries requiring tight tolerances and complex geometries, such as aerospace, automotive, and medical devices.

What are the advantages of CNC turning?

CNC turning offers several advantages over traditional turning methods:

More Precision: CNC turning can achieve tight tolerances of approximately ±0.0025 mm, ensuring high part accuracy.

Consistency: Because the machining process is computer-controlled, human error is minimized, ensuring consistency from part to part.

Fast Manufacturing: Computer-controlled manufacturing processes shorten production time and improve overall efficiency.

Lower Production Costs: Reduced operator control and intervention in tool path reduces production costs.

Safer: CNC machine tool design reduces operator exposure to moving parts, improving workplace safety.

The Difference Between CNC Turning and Milling

The primary difference between CNC turning and milling lies in the method of motion:

Turning: During turning, the workpiece rotates while the cutter remains stationary. This method is suitable for manufacturing cylindrical or conical parts.

Milling: During milling, the workpiece is stationary while the milling cutter rotates. This method is often used to produce flat surfaces, slots, or other complex shapes.

CNC turning is suitable for cylindrical or conical parts; CNC milling is recommended for flat surfaces or other complex shapes. Our engineers will help you determine which process best suits your specific needs.
