3-axis CNC vertical grinding machine

Machine main structure, configuration:

GKW28250 three axis vertical NC grinding machine, control system using Siemens 840D. A fixture to grinding inner hole, excircle, end, various raceway surface.

Standard machine configuration using double column single mill stand with NC rotary turret, turret two vertical wheelhead layout, grinding head can be automatic rotary angle. One head for cylindrical bore, excircle, straight raceway, conical surface grinding head straight, another for arc raceway, ball grinding, special type surface. Another head can also be matched with end face grinding and other configuration. The grinding head is equipped with stepless speed regulation.

The reciprocating grinding rack, Z axis adopts imported hydraulic balancing device, improve the stability and the implementation of components of life. Mill frame assurance, power-off situation can prevent the knife and cut off the self-locking, after grinding mill frame under the action of gravity decline.

In order to ensure the rigidity of the machine tool, machine tool used in Germany imported FAG/INA high vibration resistance of the roller linear guide, and equipped with damping device, effectively absorb vibration, reducing grinding chatter.

CNC turret used in Germany imported products, driven by Siemens servo motor, positioning the tooth plate positioning. The turret automatic ± 180 degrees, the turret can be installed on the two head, and can according to user requirements with hard turning tool. Vertical grinding head adopts imported high precision, high rigidity of the Spanish MYL grinding wheel, motor direct drive, variable frequency adjusting speed.

The workpiece spindle the spindle, the spindle radial, double support, ensure high radial load carrying capacity, axial, each support, lower supporting console surface floating quantity, upper support part weight and chuck weight. Precision reducer drive the unloading belt pulley, the belt pulley drives the workpiece spindle. The Finland VACON inverter VVVF speed.

Machine tool X axis and.Z axis can be equipped with Heidehan grating closed-loop control.

The machine is equipped with single point diamond dresser a dresser for circular arc, and a set of a set of molding dressing diamond dressing roller.

The electromagnetic sucking disc worktable, radial pole, used with T groove is used for mounting a workpiece support. According to the workpiece size, electromagnetic sucking disc magnetic force adjustable, and the anti magnetic device and the loss of functional magnetic protection, with magnetic, magnetic display lamp. Chuck can be installed on the disk in the processing of 3000mm in diameter parts.

Machine tool main purpose and scope:

Mainly used for disc tooth and large fan bearings, bearing parts in the hole, the end surface and the raceway grinding. Ensure the inner hole and the end face or rolling precision and surface. Is the production of machine tool is a new generation of high precision, high efficiency. Mass production of the machine is especially suitable for automobile wheel gear and bearing, large fan bearing ring.
