The grinder is a national 863 support project in 2008.The machine tool adopts the grinding method which is based on the grinding point cut. It does not need the auxiliary mechanism such as eccentric fixture, indexing device and so on. Using imported spindle system, the maximum speed of CBN grinding wheel can reach 120m/s. We have developed the interpolation software of the crankshaft cutting point tracking and grinding, and the grinding point of the grinding wheel is always following the rotation of the crankshaft to realize the high precision grinding of the crankshaft. The feed of the grinding wheel is driven by straight line, which has the characteristics of high acceleration response. At the same time, the rigidity and the sensitivity of the grinding wheel are improved by using the sel...
MKS8140 high speed CNC Crankshaft Grinder, MKS8240 high-speed NC crankshaft grinding machine adopts imported computer and AC servo drive control system of axes motion, can be equipped with automatic measurement of radial and axial line, wheel automatic balancing system, eliminating idle and collision prevention device, and a grating with a closed-loop control. Servo motor with the knife with the knife. Connecting rod grinding machine with automatic indexing, automatic positioning, automatic clamping workpiece, loose, head and tail synchronous linkage functions. The grinding wheel is made of diamond roller dressing or diamond dressing, which has the function of grinding wheel wear compensation and automatic dressing compensation.
The machine tool is equipped with a radial automatic on-line measuring device, which realizes the full closed loop control of the X axis of the grinding wheel frame, and ensures the machining parts meet the strict precision requirement in the radial dimension. The machine equipped with dynamic balancing device, anti-collision stabilizing device and the system power supply, to ensure that the system is not due to mutation of external conditions (such as voltage fluctuation, the workpiece blank size anomaly etc.) affect the machine, greatly improve the accuracy and safety of machine tools.
