Product Description

Large Size High Speed CNC Cylindrical Grinding Machine 
BGK-500   BGDK-500    BGK-630    BGDK-630
  
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.
