High-precision CNC Vertical Compound Grinder series, are the machine tool series developed by our company according to the demand of the market and the users, suitable for the massive, multi-variety and multi-specification precision process grinding of the internal or externalr column, taper, raceway and disc of the medium and large major parts for Machine Manufacturing and Equipment Industry. The machines can make surface precision grinding of the internal or external circles, faces, form surface and taper surface in the condition of install one workpiece, which greatly shorten the production cycle, improve the process accuracy, and enlarge the application.
Main Features:
The machines employ gantry structure principle with double columns, double wheelheads, carriage-moving structure, vertical spindle and rotary table, of fine rigidity. With open-top semi-closed structure and manually-moving shield door, the machines are able to grinding various surfaces of parts through either automatic or manual (electric handwheel) control.
Located on the front and upper part of the bed, the table makes rotary movement. The spindle axial and radial of static table both adopt static technology and the static guideways of table periphery ensure the high rigidity in the case of table load. With the advantages of high movement precision, steady operation without crawling, high load capacity, fine rigidity and strong vibration, the table can deploy electro-permanent-magnetic chuck on it.
The crossrail is installed above two columns which are respectively located on the two sides of the bed. On the crossrail, there are two carriages which respectivelly install left and right wheelheads.
The wheelhead an be divided into vertical wheelhead, horizontal wheelhead, universal wheelhead and generation method wheelhead, which can form many combinations according to users’ demands. The standard combination is that the left wheelhead is vertical wheelhead and the right wheelhead is horizontal wheelhead. Without fixed configuration of wheelhead angle rotary structure, the motor power of wheelhead is 15kW. Other combination can be a vertical wheelhead with a universal wheelhead, or a vertical wheelhead with a generation method wheelhead. The vertical wheelhead has rotary and fixed two alternatives. The left wheelhead of the machine can rotate, realizing the stepless angle rotation within ±25°. The right wheelhead can also rotate when it is the universal wheelhead, with the maxium rotary angle of 0°~ + 90°and the minimum graduation anlge of 2.5°, through precision end-tooth indexing table positioning.
The machines have double wheel dressers. Each side of the table is installed a wheel dresser to conduct dressing for the wheelhead according to special needs and reduce the wheelhead travel when dressing the grinding wheel , so as to improve working efficiency. There are multiple choices of the dressers: Fixed Diamond Dresser, CNC Roller Dresser and Arc Dresser.
