What is CNC Turning?

CNC turning is a process where a workpiece is rotated while a single-point cutting tool removes material to create cylindrical parts. This method is ideal for producing symmetrical components like shafts, rods, and bushings. The steps involved in CNC turning are:

• The workpiece is clamped in a chuck and rotated at high speed.
• The cutting tool moves linearly to remove material from the workpiece.
• Complex geometries can be achieved by combining multiple axes of movement.

What is CNC Milling?

CNC milling, on the other hand, involves a rotating multi-point cutting tool that removes material from a stationary workpiece. This process is versatile and can create a wide range of shapes, including flat surfaces, slots, and intricate 3D contours. The steps in CNC milling include:

• The workpiece is fixed on a table, and the cutting tool rotates at high speed.
• The tool moves along multiple axes (X, Y, and Z) to shape the workpiece.
• Complex parts can be produced by combining different milling operations.

Why Choose CNC Turning Over Milling?

CNC turning is preferred for producing cylindrical or conical parts with high precision and efficiency.
