LSK57 series CNC high-speed hard drawing machine

The LSK57 series is a new product independently developed by our company with intellectual property rights. The main components are manufactured using 3D modeling and 3D analysis, employing advanced processes and methods to create the first domestic high-speed CNC pull-type hard pulling machine. This equipment can perform thermal post-pulling on high-precision internal splines, with the hardness of the pulled workpiece reaching above HRC60, and it can continuously produce with an automatic loading and unloading robotic arm.

Equipment Highlights

High speed, hard pulling, intelligent, high efficiency, high precision, high stability, environmentally friendly.

1. Advantages and characteristics of the pulling machine:

1. The main motion guide rail uses high-precision linear guide pairs from Rexroth, ensuring pulling accuracy;

2. Full escort pulling method, ensuring the stability of the pulling tool during the pulling process;

3. Both the main pulling motion and the auxiliary motion of the tool transfer are driven by servo motors;

4. Automatic cooling and chip removal system;

5. Safety protection system;

6. Uses a self-developed CNC system with deep secondary development;
