CNC Vertical GrindingMachine
Features
1. Standardconfiguration of the CNC vertical grindingmachineis a CNC FANUC system and SIEMENS-810D/840D systems. Other systemsare optional.
2. Every vertical grinding machine has anindeterminate beam. It uses one singlecolumn structure if the rotary table's size is not bigger than 1.6M,or a gantry structure with double vertical columns if the rotary table's sizeis bigger than1.6M.
3. The CNC verticalgrinding machineuses two grinding heads with different layouts: two vertical grinding heads,one vertical grinding head and the other horizontal end facegrinding head or one vertical grinding head and the other generating grindinghead. Both the vertical grinding headand the horizontal grinding head can realize stepless speed with high precision.
4. The guide wayof the CNC vertical grinding machine usesan imported linear roller guide with high anti vibrationand the ball screw has the pretension structure. Both the guide wayand ball screw have a central lubrication system.
5. The grinding head of the CNC vertical grinding machine uses mechanical structure and thespindle bearing is pre pressingangular contact bearing.
6. The upper and lower reciprocating of thegrinding frame uses hydraulic balance. The grinding head can rotate ±90° with worm and the worm wheel structuredriven by servo motor, and the grinding head is with the hydraulic lock state,high precision angle encoder and high precision indexing.
7. The rotary table witha hydrostatic spindle structure is supported by a closed hydrostatic guide wayand the rotary table is driven by a motor with the decelerating mechanism and asynchronous belt.
8. The rotary table of the CNC vertical grinding machine is configured with T shapegroove disc, and the electric permanent magnet sucker or other special fixtureis optional.
9. The machine uses the closed loop control of thehigh precision linear grid ruler.
10. The CNC vertical grinding machine usessingle dot linear G/W dresser, and the arc G/W dresser or diamond rollerdresser is optional.
11. The machine can be configured with G/W changingassistant fixture and G/W static balance system.
Application
The CNCvertical grinding machine is used in internal grinding, cylindrical grinding, end face grinding, conical end face grinding and inner or outer track grinding for big ring shaped work pieces,extra big bearings and fan bearings. Different required surface grinding can be finished in one time ofclamping to make sure of the grinded surfaces’ position precision. The CNCvertical grinding machine is especially suitable for mass production of largegearbox casings, wind turbine gearbox bearing rings and other big bearingrings.
