Main Characteristics:

MX-400 CNC Vertical Grinder is a universal grinder with joint travel over 4 axes by using Siemens 828D control system. One clamping can grind various special shapes such as ID, OD, end face,  surface of the part.

It adopts a double-grinding frame structure. According to the needs of processing parts, two vertical grinding spindles can be selected; one vertical grinding head and one horizontal grinding spindle. Both vertical and horizontal high-precision grinding spindles are driven by frequency converters for speed regulation. The rotating speed of the grinding spindle can be equipped with high and low speed according to the required processing size.

The guide rail adopts Japanese THK roller guide with high precision and high vibration resistance. The ball screw adopts high-precision THK ball screw.

The workpiece spindle adopts a sleeve spindle, and the bearing adopts a high-precision grouped angular contact spindle bearing.

Vertical grinding frames adopts the hydraulic balance device to balance the gravity, which improves the balance when moving up and down and the life of the executive components.

The machine guide rails and ball screws are automatically lubricated by the lubrication station. And there are sealed covers for protection.

The machine can be equipped with pneumatic pitch circle positioning gear automatic fixture, three-jaw fixture, four-jaw fixture, electromagnetic chuck and various special fixtures.

Grinding coolant filter adopts magnetic and paper precision filter device.

The machine tool can be equipped with a diamond roller dresser and a single-point diamond pen dresser.

The machine’S X1X2Z1 and Z2 servo axis can adopt the Heidenhain linear encoders to form a closed-loop control.

The machine tool adopts a fully enclosed housing, and an optional oil mist separator.

Main Application:

It is mainly used for precision grinding of ID, OD, end faces, and conical surfaces of disk-shaped parts such as gears, bearings, and shaft sleeves. The grinding of each surface is completed at one time to ensure the position accuracy of each grinding surface. It is a new generation of high-precision and high-efficiency production machine tools. The entire grinding cycle of the machine tool is automatically completed, and the operator only needs to assemble and disassemble the workpiece. This machine tool is especially suitable for mass production of gears and bearing rings.
