CNC Gear Grinding: Technology, Process Selection & Application Guide

CNC gear grinding is the precision finishing process used to achieve the highest gear accuracy classifications — DIN 4 and above — by removing material from hardened gear tooth flanks using abrasive grinding wheels under full CNC axis control. It is the final and most critical step in gear manufacturing, correcting heat treatment distortions and establishing exact tooth profile geometry, lead accuracy, and surface finish quality.

Ever-power designs and manufactures CNC gear grinding machines for both profile gear grinding and generating gear grinding processes. Profile grinding follows the exact tooth space geometry and suits small batches and complex gear forms. Generating grinding uses a threaded grinding wheel in continuous mesh, delivering higher productivity for medium and high-volume automotive and industrial gear production.

Grinding Wheel TypeCorundum / CBN
Process TypeProfile / Generating
For automotive transmission gears where cycle time and wheel life directly affect cost per part, generating grinding with CBN wheels is typically the most productive solution. For aerospace gears, specialty gearbox components, or prototype runs requiring DIN 4 accuracy on varied gear forms, profile grinding offers the flexibility to address complex geometries without the changeover costs of a generating approach.
CBN wheels are preferred for case-hardened steel gears in high-volume production: they offer substantially longer wheel life, consistent accuracy over thousands of parts, and faster cycle times. Conventional corundum wheels remain cost-effective for small batches, softer materials, or applications where flexibility across gear modules is more important than throughput rate.
Ever-power provides CMM-verified gear accuracy reports covering profile deviation (ff, Ff), lead error (fh, Fh), pitch deviation (fu, fp, Fp), and surface finish Ra measurements. Documentation is provided per DIN 3962/3963 standards and can be configured to AGMA 2000 format on request.
Automotive transmission and e-axle gear production are the largest application segment. Wind turbine gearboxes (planet gears, ring gears), aerospace actuation system gears, precision industrial gearboxes, and marine propulsion gears are major secondary markets. Any application requiring DIN 5 or better gear quality benefits from a final gear grinding operation.

CNC Hobbing Machines: High-Productivity Gear Cutting for Diverse Gear Types

CNC gear hobbing is the primary soft cutting process for producing spur gears, helical gears, worm wheels, sprockets, and splines prior to heat treatment. Modern full-CNC hobbing machines replace the mechanical gearbox with an electronic synchronization system, enabling rapid changeover between gear geometries, automatic hob shifting, and consistent accuracy across entire production runs.

Ever-power's CNC hobbing machine range covers small-module precision gear production through to large-diameter, large-module gear sets for wind turbine and heavy industrial gearbox applications. The electronic gearbox eliminates the need for change gears, reducing setup time dramatically while improving helix angle and lead consistency across the full face width of the gear.

Gear TypesSpur, helical, worm, sprocket
The electronic gearbox replaces mechanical change gears with CNC-controlled synchronization between the hob spindle, workpiece rotation, and axial feed axes. This eliminates manual indexing errors, allows any helix angle without physical gear changes, and enables automatic compensation for thermal growth during long production runs.
HSS hobs with TiN or TiAlN coating are cost-effective for medium-volume production on steel gears. Solid carbide hobs offer significant speed advantage on small-module gears and hard materials, but require a machine with sufficient spindle rigidity. TiAlN-coated HSS with dry cutting capability is the most versatile choice for high-volume production of module 1 to 6 gears.
Yes. Worm wheel hobbing uses a specialized flying hob (single-start hob matching the worm geometry) in a tangential infeed operation. Ever-power hobbing machines support worm wheel hobbing with appropriate B-axis tilting and tangential feed axis configuration. Worm wheel accuracy is typically DIN 7 to DIN 9, suitable for most power transmission and indexing applications.
Module 12 to 25 wind gear hobbing requires robust machine structure, high torque at low spindle speeds, and precise thermal management across extended cutting cycles. Ever-power large-format hobbing machines feature hydrostatic rotary tables, box guideway construction, and active thermal compensation for reliable accuracy on face widths up to 600 mm on large planetary ring gears and sun gears.

Machining Centers: Integrating Precision Component Production with Gear Manufacturing

Ever-power's vertical machining centers, horizontal machining centers, and turning-milling composite centers form the foundation of precision component production lines in automotive, aerospace, energy, and heavy industry applications worldwide. The product range addresses the full spectrum of prismatic and rotational component machining, from high-speed drilling and tapping in compact drill tap centers to complex 5-axis simultaneous machining of aerospace structural components.

The integration of gear production equipment with adjacent machining capability on a single technology platform is an increasing requirement among manufacturers seeking to consolidate supplier relationships, standardize control systems, and simplify spare parts inventories. Ever-power's position as a manufacturer across both gear-specific equipment and general-purpose machining centers makes this consolidation straightforward.

CNC LatheShafts, flanges, bushings, turning
Whirlwind MillingLead screws, worm shafts, thread milling
Vertical machining centers offer lower capital cost, easier setup access, and are the right choice for single-face milling of flat components, molds, and fixtures. Horizontal machining centers with pallet changers deliver higher productivity on multi-face prismatic parts (gearbox housings, engine blocks, hydraulic manifolds) because gravity aids chip evacuation and pallet change enables continuous unmanned operation.
Turning-milling composite centers are most effective when parts require both rotational turning features (OD, bores, threads) and milled features (flats, slots, cross-holes) that cannot be efficiently completed in separate setups. For shaft components with keyways, cam profiles, or eccentric bores, a turning-milling center can reduce part handling by four to six setups and deliver 30 to 50% cycle time savings versus sequential machine routing.
Ever-power machining centers are available with Fanuc 0i-MF Plus, Fanuc 31i, Siemens 840D sl, and Mitsubishi M80 control options depending on machine type and market requirement. Control selection affects CAM post-processor compatibility and spare parts availability; our application team can advise based on your existing control environment and service infrastructure.

Material GradeHSS-E PM / Solid Carbide
Coating OptionsTiN / TiAlN / AlCrN / uncoated
DIN 3968 Class AA hobs have the tightest profile tolerances and are required to achieve DIN 5 or better gear accuracy. Class A hobs are suited to DIN 6-7 applications and offer better price-to-performance ratio for general industrial gears. Class B hobs are standard-grade tools for DIN 8 and coarser accuracy requirements where output gear quality is less critical. Always specify hob class based on the required finished gear DIN class, not the machine specification.
TiN coating is the standard entry-level upgrade, offering moderate improvement in tool life versus uncoated HSS on low-alloy steel. TiAlN is recommended for dry cutting of case-hardening steels and higher cutting speeds. AlCrN offers superior oxidation resistance above 900 degrees C and is the coating of choice for PM steels and stainless gear materials. Carbide hobs are typically used uncoated or with a TiAlN coating for maximum edge sharpness on small-module fine pitch gears.
Yes. Ever-power manufactures custom gear hobs to customer-supplied gear drawings, including non-standard pressure angles, involute modifications (tip relief, root relief, protuberance), worm wheel hobs matched to specific worm geometry, and spline hobs to DIN 5480 and ANSI B92. Lead time for custom hobs is typically 3 to 6 weeks from drawing approval. Submit a hob inquiry with your gear specification drawing via our contact form.
A standard HSS gear hob can typically be resharpened 8 to 15 times before the body diameter is reduced below the minimum specification, depending on original stock and resharpen depth per cycle. Each resharpen recovers approximately 0.15 to 0.25 mm of stock. Carbide hobs have narrower resharpen margins but longer intervals between sharpenings, so total tool life per hob body is comparable. Ever-power can advise on resharpen protocol for specific hob types.
