Product Description

high quality MY4080 saddle moving flat hydraulic surface grinder machine 

3-axis manual operation
High rigidity H-frame column with spindle center to table
Enhanced ribbed full cast iron base
Enlarged spindle housing for heavier grinding
Cartridge w / 4 preloaded class 7 (P4) bearing
Roller steel balls on linear table ways for easy and smooth longitudinal movements.

Double-V saddle ways for rigidity
Manual lubrication system

They have compact construction, excellent capability, and suitable to grinding surface and complex form surface by form dressed whell. This kind of machine can be performed without power feeding. The distance between the grinding wheel and working table has been enlarged because of its reliablity, flexibility, high accuracy, high rigidity, small thermo-deformation and low noise.
1 Adopt the exceeding precise class7(P4 level) ball bearing for spindle
2 Bring transmission by synchronous belt, operating simple and convenient
Grinding Machine/Grinder (M820)
Hydraulic longitudinal, power corss and vertical hand infeeds operation.
All 3 axises are roller bearing slides

Hardened & ground ways (removable) on table, carriage / saddle & column
Cartridge spindle W/ 4 preloaded class 7 (P4) bearing for better workpiece accuracy.

Table, saddle & column move on linear table ways MID-level downfeed handfeel placement for convenient and easy position for Z-axis.
