Hobs, shaper and skiving cutters for small-module and precision gears. Made to order to your drawings.

Precision Cutting Tools for Fine-Tooth Gear Production
Gear cutting tools for small-module external and internal gear features — engineered around the complete gear specification, workpiece material, machine kinematics, tool interface, and inspection target.
Small-module work leaves little room for incomplete data. The tool geometry, cutting strategy, setup, and inspection plan must be considered as one production system.
Tool profile, starts, lead, rake, relief, and cutting-edge preparation can be evaluated for suitable external gear and spline hobbing operations.
Cutter geometry, clearance, stroke conditions, and workpiece access can be reviewed for suitable internal, external, and shouldered features.
Form cutters can be considered for drawing-defined tooth spaces, prototypes, lower-volume work, and features that suit indexed machining.
Special tooth forms, splines, serrations, and drawing-defined profiles can be evaluated after the controlled gear data and machine setup are confirmed.
Provide the gear type, module or diametral pitch, pressure angle, tooth count, internal or external condition, helix angle and hand, profile shift or modification, root and tip requirements, face width, governing standard and accuracy class, workpiece material and hardness, blank condition, machine model, tool interface, coolant method, inspection plan, and production volume. JIAYI will confirm the feasible tool concept after reviewing the complete application.

View ProductsWe are still adding this range to our online catalog. These tools are available made to order: send your drawing or sample and we will quote sizes, lead time and price, or contact our team for current availability.
Tools in this category are produced on request to your drawing, sample or specification. Send us your requirements and our engineers will reply within 24 hours.
Profile-led engineering. The proposed cutter geometry begins with the controlled gear specification, required tooth form, cutting method, and inspection criteria.
System-level application review. Runout, alignment, rigidity, workholding, machine synchronization, chip control, and tool interface are reviewed alongside the cutter.
Drawing-based custom capability. Non-standard profiles and special interfaces can be developed from approved drawings after the technical scope is confirmed.
Send the controlled gear drawing, applicable standard, inspection requirements, workpiece material and hardness, blank details, machine and interface data, current process, and production target. Our engineering team will review the profile and process before preparing a proposal.
