Our CNC Turning Services

Chiheng Hardware's modern and well-equipped facility specializes in precision CNC turning services, providing comprehensive lathe solutions and advanced machining capabilities for clients worldwide.
We can machine cylindrical workpieces up to 320mm in diameter and 200mm in length using our computer-controlled lathes. (Maximum dimensions, actual machining size depends on material. Longer material can accommodate larger diameters.)
Whether it's a bar or tube, we can skillfully perform operations such as drilling, slotting, tapping, and knurling to transform cylindrical materials into the desired shapes according to your drawings.
Through our online CNC machining platform, we offer instant quotes and rapid turnaround times for all your precision turning needs.

Multi-Process Machining Comparison: CNC Milling vs Turning vs Turn-milling

Turn-mill machining is particularly well-suited for producing intricate components that require both turning and milling operations. This technology enables manufacturers to create complex parts with high precision and consistency. The ability to complete multiple operations in a single setup not only improves accuracy but also reduces the potential for errors associated with part transfers between different machines.

Characteristic Turn-Milling Milling Turning
Workpiece Motion Rotates Stationary Rotates
Tool Motion Rotates and moves linearly Rotates Stationary or moves linearly
Primary Shapes Complex, cylindrical with milled features Complex, non-cylindrical Cylindrical, axially symmetrical
Setup Efficiency Single setup for multiple operations Multiple setups may be required Single setup for cylindrical parts
Production Speed High, combines operations Moderate to high High for cylindrical parts
Typical Applications Complex automotive and aerospace components Aerospace components, molds, fixtures Shafts, bushings, pistons

Turn-milling offers several advantages over traditional milling and turning processes. It reduces setup times and part handling, improving accuracy through single-setup machining. This integrated approach allows for the production of complex parts with both turned and milled features in one operation, significantly increasing efficiency. Additionally, turn-milling machines can achieve higher cutting speeds and feed rates compared to conventional turning, resulting in improved surface finishes and potentially longer tool life.
