RE-SHARPENING MACHINE

A re-sharpening machine is a specialized tool used to restore the cutting edges of worn or dull cutting tools, such as drills, end mills, or reamers, to their original sharpness. This process extends the life of the tools, improves cutting performance, and reduces the cost of frequently purchasing new tools.

To meet the needs of different industries, Li-Hsun's drill bit grinders and milling cutter grinders are widely used for grinding various drill bits and milling cutters. The tool positioning is precise, and the grinding size is as small as 2mm. With special cylinder clamps, it can reach 30mm. The grinding wheel of the re-sharpening machine rotates at high speeds to carefully grind and reshape the tool's cutting edges, removing worn material and restoring sharpness.

ENDMILL HELIX RE-SHARPENING EH TYPE

The universal tool & cutter grinder Model EH-832 is versatile in operation without requiring special skills. All milling cutters, endmills, shell endmills,staggered tooth cutters, rough endmills, countersinks (2 flutes, 4 flutes) and the angle of endmill helix can sharpen 2, 3, 4, 5, 6 flutes.
The Model EH-832 is designed to sharpen HSS and carbide toolings in small and medium quantities.
In one chucking operation, the machine can perform the grinding of the rake angle of the flute, clearance angle on the periphery and the end of the tool.
A few seconds set up time for helix angle.
Due to the backlash free operation, spiral toothed, solid carbide or carbide tipped milling cutters can be ground with high accuracy thus far only achieved by CNC grinders.
The heavy duty compound slides and one piece cast-iron base provide extra rigidity and minimize vibration.
