Product Description

 

Roduct Description

Precision Slant Bed CNC Lathe for Crankshaft Spindle Production CKY4380

 
 

The main performance characteristic
 

This series of CNC crankshaft connecting rod journal lathes are specifically designed for precision turning of connecting rod journals in motorcycle, automotive, diesel engine, heavy-duty truck, and large marine crankshafts. They replace rough grinding processes with high-speed, high-precision turning.

Features

1. The overall bed is cast from high-quality, high-strength cast iron, providing excellent rigidity and precision.
2. The surface of the guideways undergoes ultrasonic frequency quenching treatment, resulting in high hardness and long service life.
3. The carriage adopts a plastic-lined guideway surface process, which enhances wear resistance and precision.
4. The spindle bore is large, allowing for high passability, and the dual chuck clamping of workpieces ensures stability.
