Overview of 3HG Universal Vertical Turret Manual Milling Machine

Turret milling machine can be widely used to process plane, inclined plane at any angle, milling keyway and groove, and can also rotate, ream and bore. Its milling head can rotate 90 degrees left and right, 45 degrees front and rear, and the RAM can rotate 360 degrees horizontally. the spindle has a large speed change range and high speed. the spindle sleeve can be motorized for fixed distance feeding, and is equipped with overload protection device. Spindle sleeve, airport guide rail and worktable are all hardened by high frequency, beautiful and practical. the vertical turret milling machine can be equipped with motorized feeding device and digital display system.

Maintenance of 3HG Universal Vertical Turret Manual Milling Machine

1. Cleaning: disassemble and clean the oil wool felt pad of each part; Wipe each sliding surface and guide rail surface, wipe the workbench and transverse, lifting screw rod, wipe the tool feeder and tool holder.

2. Lubrication: keep all oil holes clean and unblocked and fill 32# lubricating oil; Fill lubricating oil at each guide rail surface, sliding surface and screw rod; Check the oil pot and oil level, and add oil to the elevation.

3. Tightening: check and tighten the pressing plate and insert screw; Check and tighten the limit screw of the worktable, the driving mechanism of the tool walker, the three ball handle and the screw of the worktable support.

4. Adjustment: check and adjust the tightness of milling head belt, pressing plate and insert strip; Check and adjust the clearance of limit stop and screw rod.

5. Anti corrosion: remove the rust of each part, protect the painted surface from collision; the guide rail surface of inactive and standby equipment, sliding screw, handwheel and other exposed parts prone to rust shall be coated with oil for anti-corrosion.
