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...

CNC8325B camshaft NC high speed compound grinder
产品名称:

CNC8325B camshaft NC high speed compound grinder

上市日期: 2017-02-28

This machine is a non template CNC camshaft multifunctional composite grinding machine, SIEMENS 840D CNC system, four three axis machine tool with full closed structure. On the basis of the CNC camshaft grinding machine, the camshaft compound grinding machine is developed successfully.

The device is 2008 National 863 support program.

The machine adopts the square structure layout, the tail frame is fixedly mounted on the bed rails, torque motor driven rotating workpiece, grinding wheel can move around and around, modular installation of multiple spindle according to functional requirements, selection and rotation of accurate positioning, to achieve compound machining camshaft.

Main structure and technical characteristics

Grinding wheel spindle system

The big wheel spindle system with built-in motor spindle, the maximum speed is 8000RPM, the use of inverter control, with a constant temperature device, pressure seal, spindle installed non-contact dynamic balancing system was built and integrated installation process, eliminating empty collision and repair AE monitoring device, to ensure the effective use of CBN wheel safety, integrated in 840D the display of dynamic balance and AE monitoring; small wheel spindle system with AC spindle motor through a belt drive spindle, the maximum speed is 15000RPM, two spindle system 90 installed in NC precision table, can be opened at the same time, also can only use a grinding wheel, according to need to choose.

Grinding wheel slide

Under the guide of V- calm unloading rail, realize wheel frame longitudinal movement, resolution of 0.001mm, repetitive positioning accuracy is 0.01mm; the upper rail is THK linear guide, THK adopts screw driver to achieve horizontal feed wheel frame (x axis), using the German HEIDENHAIN linear grating to realize closed-loop control;

Imported rotary table

Imported rotary turntable, turntable servo drive, hydraulic lock, air pressure seal.
