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

Robust Tooling for High-Stock-Removal Gear Machining
Gear cutting tools for large-module external and internal gear features — configured around tooth geometry, stock allowance, workpiece material, machine power and rigidity, tool interface, chip control, and the required finishing strategy.
Large tooth spaces increase engagement and material removal. Tool construction, pass strategy, workholding, chip evacuation, and finishing allowance must be coordinated before production.
The cutting concept can be structured around stock distribution, stable engagement, machine capability, chip evacuation, and controlled allowance for later operations.
Finishing geometry and process conditions are evaluated against the required profile, lead, surface condition, and inspection method.
Tool form, dimensions, interface, and cutting sequence can be reviewed for suitable external or internal gear-manufacturing applications.
Drawing-based profiles, special interfaces, and operation-specific cutter designs can be evaluated after the workpiece and machine data 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, stock allowance, governing standard and accuracy class, workpiece material and hardness, blank condition, machine power and travel limits, tool interface, coolant and chip-management method, finishing sequence, inspection plan, and production volume. The proposed solution must fit both the geometry and the available machine process.
