Gear Finishing & Surface Treatment

Corrects what hardening distorts

Heavy-duty spindle lapping that removes the high points which appear on gear teeth after hardening. All motions are controlled from the panel, with variable spindle speed in both forward and reverse, and the machine is modified to suit your gear.

The Problem It Solves

Why hardened gears still need finishing

Heat treatment gives a gear the hardness it needs, but it also distorts the tooth form. Microscopic high points appear on the flanks, and those points carry the entire contact load when the gear first meshes.

Lapping removes exactly those high points, restoring the contact pattern across the full flank. The result is quieter running, better load distribution and a gear that does not wear itself in at the customer’s cost.

Our Offerings & Technology

How we build the machine

Key Features & Advantages

Built for repeatable tooth geometry

01

Rigid spindle

A heavy-duty spindle assembly keeps the lap running true, so correction is even across the whole flank.

02

Bi-directional lapping

Forward and reverse motion works both tooth flanks evenly instead of loading one side.

03

Panel controlled

Speed, direction and cycle time are all set and repeated from the control panel, not by operator judgement.

04

Restores contact pattern

High points come off, the contact band spreads across the flank, and gear noise drops measurably.

05

Component specific

Fixturing is built around your gear rather than adapted from a standard holder.

06

Serviceable

Standard bought-out drives and bearings, with spares held and supplied from Faridabad.
