Main Outlook

Summary

Machine Summary

BGK-500/BGK-630 and BGDK-500/BGDK-630 CNC (end face) cylindrical grinding machines are large-size CNC machine tools independently designed, developed and manufactured through the company's import, digestion and absorption of overseas & domestic advanced technologies. They are characterized by the universalization, high-degree modularization, high rigidity, high efficiency and high adaptability. Being large-size CNC cylindrical grinding machines of convenient operations, reliable performance and high processing precision, the series of machine tools are suitable for mass production of production for parts of large-size shaft parts.

Main Performances

Features and Performance

With the rational layout and integral protective cover, the machine is convenient for maintenance and in conformity with human engineering requirements.
The grinding wheel spindle adopts a structure of sleeve type high-rigidity hydrostatic/hydrodynamic mainshafting and features on its high rotary precision and strong bearing capacity. The linear velocity of the grinding wheel can be up to 60m/s(specially ordered).
With two-axis linkage feeding, the machine tool is equipped with worktable(Z-axis) and wheel head (X-axis) driven by AC servomotor and ball screws. With plastic-filming guideway being used and on the adoption of the closed multi-points lubrication, it features on vibration absorbing and anti-friction as well as good precision maintenance.
The machine can be provided with various diamond dressers according to customers' needs, thus realizing precise dressing of complex grinding wheel surfaces and automatic compensation.
Equipped with an imported or a domestic active measuring device, the closed-loop control of grinding process is realized.
Adopting an imported advanced CNC system, the machine features on the menu type interface input and the control up to four axes(X, Z, U and W axes) so as to meet the requirements of grinding and dressing cycles.
The machine may optionally equipped with a CNC or a hydraulic driven auto-tracing center rest dedicated for processing of long and thin shaft parts.
