Product Description

Double Oil-Cylinder CNC Internal Pull Broaching Machine
LVK-1012S     LVK-2016S    LVK-4020S    LVK-5020S

Performance and Features
Designed as per advanced international technology standards, the machine meets the requirements of high-power cutting technology and stable cutting technology under mutiple vibration sources. Its structure and kinematical mechanics conform with the principle of broaching engineering mechanics, which increases the service life of cutting tool. With high technology standard of accuracy, safety, function, etc, the machine can be used efficiently.

The machine uses a method of advanced mechanical design. As main bearing parts of the machine is highly symmetrical in structure, the acting force is even and symmetrical during working process and there is no bias torque, which minimize the effect of deformation and wear extent of main force bearing components on the radial and axial accuracy of workpiece. Thus, the machine has high accuracy stability and long service life.
The machine has mature system, technology and management function. With ground installation and humanism operation, the machine is numerical controlled, autonomical and intelligent.

The machine has high accuracy, high quality, high stability and high efficiency.
Equipped with suspension type automatical tool changer. Workpiece can be loaded and unloaded automatically twice. Ground type installation.

Machine Applications
The machine is applicable to machining various types of internal spline, internal gears, round holes, square holes, polygonal holes and other irregularly-shaped holes. The machine is suiable for parts with the requirements of mass production and high accuracy, and can be used in automatical production line.
