Gear Grinding
Finish grinding of hardened gear teeth to correct the distortion left by heat treatment. Profile, lead and pitch are brought back inside tolerance, and those three decide gear noise and load capacity. SES holds the range as an authorised Tyrolit distributor, covering wheel types Grinding worms, profile wheels, bevel cup wheels; abrasives Sintered and ceramic aluminium oxide, CBN; bonds Vitrified, plated, hybrid; module range Fine pitch through to large industrial modules. Executions include dressable grinding worms, profile (form) grinding wheels, bevel gear grinding cup wheels, plated CBN gear wheels, among others. It is specified most often into gearbox pinions for mill and crusher drives and automotive transmission gears. Every part is genuine Tyrolit through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Gear Grinding in the parts of a plant where this particular duty actually occurs. In practice that means gearbox pinions for mill and crusher drives, automotive transmission gears, wind turbine gearbox stages, and equally marine and industrial reduction gearing, aerospace accessory drive gears, rebuilt gears in a plant workshop after case hardening. What links them is the duty rather than the machine name — methods: Generating (worm) and profile (form). If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the Tyrolit range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. High volume of similar modules — A dressable grinding worm on a generating machine. Cycle time per gear drops sharply once the dressing programme is settled. Large modules, or small batches across many profiles — Profile grinding with a dressable form wheel. It is slower per gear, but changeover becomes a programme rather than new tooling. Grinding burn showing on the flank under Nital etch — An open-structure ceramic wheel and more coolant volume into the mesh. Burn on a case-hardened flank is scrap, not rework. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Ask for an etch check on the first ground gear of any new specification, not on the last one of the run. Grinding burn is invisible on a bright flank and announces itself two thousand hours later as pitting on the drive side.
