Harbin Tool / Harbin Tool Works Precision Gear Cutting Tools and Tooling
High-precision gear hobs, gear shaper cutters, disc shaving cutters GB/T14333, broaches, and spiral bevel cutter heads by Harbin Tool Works. Industrial tooling from Harbin, China.
Harbin Tool Works Gear Hobs for Spur and Helical Gears
Harbin Tool Works gear hobs deliver high-precision cutting for spur, helical, and spline gears. Built from M35/M42 cobalt high-speed steel and solid carbide inserts, they support dry high-speed hobbing. Custom profile modifications meet demanding vehicle transmission requirements.
- High accuracy classes AA, A, and B per gear standards
- High-grade M35/M42 HSS-Co and solid carbide construction
- Module range from 0.5 to 25 mm for external gear teeth
- Advanced Balzers PVD wear-resistant coating application
Harbin Tool Works Gear Shaper Cutters and Broaching Tools
Harbin Tool Works manufactures precision gear shaper cutters and internal broaches from premium M35/M42 cobalt high-speed steel. Engineered for CNC shaping and broaching machines, they produce high-accuracy internal and external gear teeth, splines, and keyways across tough alloy steels.
- Disc, cup, and shank designs for versatile shaping setups
- Involute spline, parallel spline, round, and keyway broaches
- Broach lengths up to 2000 mm with fine sizing tooth sections
- Wear-resistant PVD treatment delivering long working life
Harbin Tool Works Precision Gear Shaving Cutters GB/T14333
Harbin Tool Works disc-type gear shaving cutters comply with GB/T14333-1993 for precision finishing of pre-hobbed gear teeth. They eliminate profile deviations, reduce roughness, and correct pitch errors. Tailored crowning ensures smooth and low-noise gear transmission performance.
- Engineered to standard GB/T14333-1993
- Micro-slotted tooth flanks for superior metal shaving
- Significantly decreases transmission operating noise
- Custom tip relief and crowning tooth geometry calculation
Harbin Tool Works Spiral Bevel Gear Cutter Heads and Blades
Harbin Tool Works spiral bevel gear cutter heads and blades are built for Klingelnberg and Oerlikon gear manufacturing systems. The rigid cutter body ensures zero deflection during rough and finish cutting of hypoid gears. Replacement blades are coated with Balzers PVD to resist severe loads.
- Engineered for Klingelnberg and Oerlikon gear systems
- Interchangeable inner, outer, and bottom blade sets
- Extreme cutter body rigidity for vibration-free milling
- Regrindable geometry backed by wear-resistant PVD
Engineering Specifications of Harbin Tool Works Gear Hobs and Tooling Systems
Harbin Tool Works manufactures precision gear hobs featuring single-thread and multi-thread geometries for cutting external spur and helical gears.
The tooling range includes solid M35 (5% cobalt) and M42 (8% cobalt) high-speed steels, as well as indexable carbide insert configurations designed for heavy-duty CNC hobbing equipment.
Tool accuracy conforms strictly to Class AA and Class A standards under DIN 3968 specifications. Optimized rake angles and radial relief ensure balanced chip thickness distribution across all cutting teeth, suppressing chatter and vibration under accelerated axial feeds.
Advanced PVD Coating and Vacuum Heat Treatment Standards
Harbin Tool Works employs Swiss Balzers vacuum deposition equipment to apply specialized PVD coatings onto precision gear-cutting tools.
Depending on cutting conditions, TiN, TiAlN, and AlCrN coatings are deposited with thicknesses of 2–4 micrometers, providing superior surface microhardness and thermal stability exceeding 900 °C.
Tool steel blanks undergo computer-controlled vacuum hardening and multi-stage tempering using advanced German thermal equipment. This process establishes a uniform martensitic microstructure with minimal residual stresses, ensuring strict pitch retention across multiple regrinding cycles.
