How an RFQ becomes a running gear
Five stages, one accountable engineer from start to finish.
Module 0.5–20, up to 1,200 mm OD. Gleason and Liebherr hobbers with on-machine probing.
Reishauer continuous-generation grinding to AGMA Class 12 / DIN 3 flank accuracy.
Involute and straight-sided splines, broached keyways, DIN 5480 and ANSI B92.1 fits.
5-axis blanks, housings and shafts machined in-cell so gears and mates always fit.
Carburizing, induction hardening and cryogenic stabilization with full furnace-charge traceability.
Worn or undocumented legacy gears scanned, re-parameterized and returned as production drawings.
Roughing and finishing hobs run on six Gleason P-series machines with automatic tool-wear compensation. Shaper cutters handle internal gears and shoulder-adjacent teeth that hobs cannot reach. Typical lot sizes range from a single prototype to 5,000-piece production releases, with quick-change workholding keeping setup under 40 minutes.
After heat treatment, gears move to continuous-generation grinding on Reishauer RZ260 cells. Lead and profile corrections are applied per part from CMM feedback, closing the loop between metrology and machining. Power honing is available for NVH-critical automotive and robotics gears where surface texture matters as much as form.
The 20°C-controlled lab runs a Klingelnberg P26 analytical gear tester alongside two Zeiss CMMs. Every critical feature on every first article is measured; production lots follow a documented AQL sampling plan. Customers receive lead, profile, pitch and runout charts with every shipment — not on request, by default.
Within 48 hours you get pricing plus a manufacturability note flagging anything that adds avoidable cost.
Workholding, hob selection and CNC programs are built and stored under your part number for repeat orders.
A complete FAI package — dimensional report, material certs, hardness map — ships before production starts.
SPC-monitored machining with in-process probing; deviations halt the cell automatically.
Documented, bagged and labeled to your spec. Field issues get an engineer on the phone the same day.
AGMA quality class
Achievable on ground gears, lead and profile.
Runout capability
Held on precision-ground production gears.
From soft-cut prototypes to hardened, ground production gears, every operation stays in-house — so the tolerance you spec is the tolerance we own.
