|---|---|
The High-Accuracy Gundrill Grinder is a specialized machine designed to recondition and manufacture gun drill tools with exceptional precision, ensuring consistent performance in deep hole drilling applications. Engineered with advanced CNC controls and a rigid granite base, this grinder restores worn gun drills to original specifications or manufactures new tools with geometries optimized for specific materials, from soft aluminum to hardened steels (60 HRC).
Precision Grinding Technology:
Five-axis CNC system with linear motors (0.001mm resolution) for grinding complex gun drill geometries: 120° split points, variable helix flutes, and wear-resistant margins.
Air-bearing spindle (0.0003mm radial runout) ensures vibration-free grinding, critical for maintaining hole straightness within 0.05mm/100mm after reconditioning.
Tool Life Enhancement:
Electrolytic in-process dressing (ELID) for CBN wheels, maintaining sharp grinding edges and achieving surface finishes on drill tips ≤Ra 0.2μm.
Automatic angle compensation for wear, restoring drill tip angles (point angle, relief angle) to ±0.1° tolerance.
Process Automation:
Vision system for automatic tool alignment, reducing setup time by 70% compared to manual grinding methods.
Data logging of grinding parameters (speed, pressure, time), providing traceable records for quality control and tool life analysis.
Critical for tool manufacturers and industrial maintenance:
Tool Reconditioning: Restoring worn gun drills (diameters 3mm-50mm) to like-new condition, extending tool life by 30% and reducing replacement costs by 50%.
Custom Tool Manufacturing: Producing gun drills with specialized geometries for composite materials (CFRP), titanium alloys, and superalloys, meeting aerospace and defense specifications.
Production Line Support: On-site grinding for high-volume manufacturers, ensuring consistent drill performance and minimizing downtime due to tool wear.
Expertise in Deep Hole Tools: 20+ years of experience grinding gun drills for industries like oil & gas, aerospace, and firearms, with knowledge of SAAMI, API, and AS9100 standards.
Rapid Turnaround: Standard reconditioning completed in 24 hours, with custom tool manufacturing lead times 40% faster than industry averages.
Calibration Services: Free annual spindle calibration and grinding wheel truing, ensuring long-term machine accuracy and repeatability (CPK ≥1.33).
