Products Description
Cylindrical Grinding Machine Feature
It is suitable for cylindrical grinder. Its accuracy is IT6-1T5. The vertical stroke of the worktable is driven by hydraulic pressure, stepless speed change, or by hand wheel lubrication. It is used for hole passing. The lateral stroke of the shaft head is equipped with hydraulic fast forward and backward manual micro-feed. It also has the function of automatic circulation of feeding grinding wheel. Workpiece, grinding wheel, oil pump and belt pulley are driven by their respective motors. Two sets of sliding bearings consisting of four bushes are used as the spindle bearings of grinding wheel. The spindle is bold, the motor is increased, and the grinding efficiency is high. The grinding wheel dresser is installed on the tile frame and the hydraulic tailstock upper back device. The machine has moving parts such as electric and hydraulic chains, which is safe and reliable to operate. this series workbench adopts hydrostatic guideway to move.


1. When conical grinding, the table can be swivelled to either side and exactly positioned by using the scale.
2. Oil film between bearing and spindle keeps vibrations ata minimum level, hence achieving outstanding results and top accuracy.
3. Precisely balanced spindle head and solid grinding head guarantee extraordinary results at any type of operation.
4. Strong reinforcements and solidly designed panels of the machine base makes it resistant to temperature fluctuations and deformations.
5. Spindle is mounted from both sides and features adjustable sliding bearings consisting of three segments.
6. Hydrodynamic bearing of spindle, therefore no contact between spindle and bearing.
7. Longitudinal table feed can be set to automatic mode -hydraulically driven or manual mode - by handwheel.
8. Stepless feed adjustments with the option of aprogrammable hold time at the end of each table movement.
9. Hydraulic or manual repositioning of grinding spindle stock.
10.Guideways in x- and y-axis are precisely constructed and hand-polished.
11.Longitudinal table guide and cross guide of grinding headstock each feature a V-guide and flat guide.
