MKS8332

CNC Camshaft Grinding Machine

Features of the machine tool performance and structure

Being a top grade CNC machine tool, MKS8332 CNC camshaft grinding machine is developed by the Company with its own design and mainly used for camshaft grinding. Based on design method of production type CNC grinding machine and non-round grinding technology, the machine tool realizes cam profile CNC linkage grinding. With strong processing flexibility, simple and reliable operation, the machine tool is with high stiffness, efficiency and reliability.

As two-axis CNC interpolation linkage is adopted for full closed-loop controlof grinding wheel feeding (X axis) and work-piece rotating (C axis), it realizes numerical control precision positioning movement of non-round cam profile, completely removes disadvantages oftraditional profilingmachine tools,suchas poor machiningflexibility, difficulty of profiling and complicated maintenance. The linear speed of CBN grinding wheel is 120m/s. It's mainly used for large scale precision processing camprofileof camshaft components for internal-combustion engines. The front side of machine tool is of vertical plane without any adjustment links, convenient for erection of additional component logistical transmission line without mutual interferences, therefore it is an optimized equipment for a production line. The machine tool is designed in conformity with related requirements on safety, environment protection and human engineering.

• • With structural layout of mechatronics and integral protective cover, the machine tool is convenient for maintenance and in conformity with human engineering requirements.
• • Due to direct driving of hydrostatic electric spindle, CBN grinding wheel features high rotation precision, retentive precision and strong rigidity. With linear speed as high as 120 m/s, the grinding wheel is equipped with built-in dynamic balance system.
• • The machine realizes three-axislinkage feeding with work head (C axis) directly driven by torque motor, positioning accuracy of 0.002 degree; wheel head(X axis) directly driven by linear motor, good dynamic response, maximum speed of 40m/min; worktable(Z axis) driven by servo motor, minimum setting unit of 0.1μm and maximum speed speed of 20m/min.
• • With the linear speedof 120m/s, CBN grinding wheel adopts diamond roller for dressing and is provided with sonar detector so as to insure trace amount precision dressing, thus extending its service life; the roller is directly driven by the electric spindle.
• • The machine tool adopts is provided with all-around controlling functions including grinding program changes, work-piece quality control, machine condition monitoring, fault self-diagnostics, abnormal alarm, and convenient menu type interface input.
