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.

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.
