Hydraulic Internal Grinding Machine

Rekha Engineering offers Hydraulic Internal Grinding Machine. The machine is suitable for precision bore grinding of small and medium work pieces. It can be used for one-off production as well as for batch production in addition to parallel grinding, the machine can be used for grinding taper bores by swivelling the work head. The machine can run on auto mode for small batch production. All movements in the machine, in addition to power, can be effected manually, thus anyone of the jobs can also be ground precisely. The machine constist of several parts such as Wheel Spindle, Main Table, Work Head Spindle, Work Head, Dressing Unit, etc.
Wheel Spindle: Rigid construction and ultra precision pre-loaded rolling bearing mounting ensures required stiffness and precise running of wheel spindle. Wide varieties of internal grinding spindles are offered to suit different sizes of components. For higher range of speeds, provision is made to mount high frequency spindles.
Main Table:
Wheel head is mounted on the table which moves on a turcite lined 'V' & flat guide ways. This ensures smooth movement of table without any stick-slip in the entire table ranges. Table travel is affected by means of hydraulic cylinder and speed can be varied by means of trip dogs provided on the table.
Work Head Spindle:
Work head spindle is mounted precision angular contact bearings to ensure high accuracy. The spindle bearings are lubricated with grease for lifetime, which ensures cool running. As an option variable speed motor can be offered to provide step less spindle speeds.
Work Head:
Work head is mounted on a swivel base, which can be swivelled between· 5&+45deg. To facilite taper grinding.
Dressing Unit:
The dressing unit is mounted on the work head slide bracket holding the diamond can be swing away from the grinding zone. The dressing is done and controlled hydraulically.
