Item Description

Features

1. Standard configuration of the CNC vertical grinding machine is a CNC FANUC system and SIEMENS-810D/840D systems. Other systems are optional.
2. Every vertical grinding machine has an indeterminate beam. It uses one single column 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 size is bigger than1.6M.
3. The CNC vertical grinding machine uses two grinding heads with different layouts: two vertical grinding heads, one vertical grinding head and the other horizontal end face grinding head or one vertical grinding head and the other generating grinding head. Both the vertical grinding head and the horizontal grinding head can realize stepless speed with high precision.
4. The guide way of the CNC vertical grinding machine uses an imported linear roller guide with high anti vibration and the ball screw has the pretension structure. Both the guide way and ball screw have a central lubrication system.
5. The grinding head of the CNC vertical grinding machine uses mechanical structure and the spindle bearing is pre pressing angular contact bearing.
6. The upper and lower reciprocating of the grinding frame uses hydraulic balance. The grinding head can rotate ±90° with worm and the worm wheel structure driven 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 with a hydrostatic spindle structure is supported by a closed hydrostatic guide way and the rotary table is driven by a motor with the decelerating mechanism and a synchronous belt.
8. The rotary table of the CNC vertical grinding machine is configured with T shape groove disc, and the electric permanent magnet sucker or other special fixture is optional.
9. The machine uses the closed loop control of the high precision linear grid ruler.
10. The CNC vertical grinding machine uses single dot linear G/W dresser, and the arc G/W dresser or diamond roller dresser is optional.
11. The machine can be configured with G/W changing assistant fixture and G/W static balance system.

 

Application 

The CNC vertical 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 of clamping to make sure of the grinded surfaces' position precision. The CNC vertical grinding machine is especially suitable for mass production of large gearbox casings, wind turbine gearbox bearing rings and other big bearing rings.
