LGK557 Series CNC Pull-up internal broaching machine

Brief description： LGK557 series CNC pull-up internal broaching machine, the structure of this machine adopts the form of double column guideway and double servo motor drive, 2 guideway centers, 2 drive centers and 1 broaching center to achieve a 5-centre co-planar, the advantage of this structure is to eliminate the overturning moment caused by the structure of the traditional broaching machine so that the workpiece in the broaching process is also subject to a uniform and symmetrical broaching force, the deformation of the table is also symmetrical offset, the workpiece positioning surface and broach axis is always perpendicular movement.

Equipment Highlights

LGK557 Series CNC Pull-up internal broaching machine

Large-tonnage pull-up internal broaching machine, double servo drive, double guide pillar, intelligence, high efficiency, high precision, high stability and environmentally friendly.

一、Advantages and features of broaching machine：

1. The main structure has a high symmetry design with 2 guide centers, 2 drive centers, 1 broaching center and a 5-centre co-planar

2. Fully escorted broaching for smooth broaching.

3. Servo motor detection for both the main broaching motion and the auxiliary tool pick-up and drop-off motion for full closed-loop control.

4. Using dual-sided operation with high flexibility

5. Kneadable, safe knife lifting devices for better knife protection.

6. Using independent, in-depth secondary development of the CNC control system.

7. Tool and fixture change aids reduce the intensity of manual operations for tool change; enhance operational safety and tool change efficiency.
