GSM Drill Bit Grinder
Drill bit grinder of GSM is consisted by fixer and grinder. They can work separately. But when use them to work together can achive a higher grinding precision and efficiency.
Is a kind of high efficient tooling of GSM for grinding.
Easy clamping and adjusting.
Drill Bit Grinder
Equipped with high precise rolling guide and high speed motor.
Smooth movement and small friction.
Grinding wheel can horizontally and vertically move.
Tool Regrinding Management
Tool regrinding management must be strictly implemented to prolong gun drill tool’s life and ensures drilling quality.
The regrinding must be practiced when:
Tool diameter D<15 and flank wear extent reaches 0.2-0.4.
Tool diameter D≥15 and flank wear extent reaches 0.4-0.6
GSM Regrinding Angle
Standard Angle for single fluted gun drill diameter ≤5.00mm
Single fluted gun drill diameter between 5.00mm and 20.00mm Standard Angle
Standard Angle for single fluted gun drill diameter ≥20.00mm
