SL118 High Precision Internal Grinding Machine



-High-strength cast iron base frame. The critical iron castings are conducted a finite element structural 

analysis. All castings are carried out double aging treatment and vibratory stress relief to ensure the stability of 

machine accuracy.

-Z-axis is designed as flat V guideway, with which axial grinding wheel oscillates, that make the machine 

worn less and extend the lifespan in the processing.

-Centerless type is designed when the concentricity of grinding between the external and the inner bore is in demand. The spindle box is fixed, the angle of which can be adjusted slightly.

-Chuck type is designed when the external and the inner bore are irregular. The workpiece can be both 

manually or automatically loaded and unloaded.

-Optional dynamic monitoring device, an adaptive control system and on-line feedback of grinding realtime state make the grinding process simplified.

-Remote control and maintenance solution via computer communications.



It is mainly suitable for the processing of internal bore and outer ring groove of bearing ring (angular 

contact, hub, cone), air-conditioning compressor (cylinder, cylinder head, roller, piston, rotor), steering gear 

(gear, bearing, steering screw), gearbox (gear, sealing ring, solenoid valve seat), engine (retainer seat, 

bushing, roller, piston, nozzle), shock absorber (bearing, bushing, valve seat), hydraulic valve sleeve, CV 

joint cage, ceramic sleeve, automobile hydraulic tappet, etc.
