Tooth By Tooth Course Pitch Hardening (Back To The Top) Sizes: From 1/2 DP to 5DP Types: Spur, Helical, Bevel, Internal, Racks Our tooth by tooth induction hardening is ideal for coarse pitch gears ranging in size from .5DP-4DP.  This produces a full tooth contoured hardness pattern (AGMA type "A"). During induction heating, an inductor is passed through the tooth space hardening only the areas affected by tooth wear.  The open air process allows hardening to proper depths while minimizing heating of adjacent teeth.  Distortion is controlled with precision scanning on CNC controlled equipment.  This induction hardening process is an excellent option compared to furnace processes such as carburizing.  By scanning individual teeth, distortion is minimized to the point that post grinding is not always necessary.  Decades of experience provide a wealth of tooling to fit almost every tooth size.

"Natco" Process Fine Pitch Hardening
(Back To The Top)

Sizes: From 4 DP to 10 DP

Types: Spur, Helical, Internal

Our submerged fine pitch gear hardening is a much sought after source for external and internal gears ranging in size from 5DP-10DP. 

Sometimes called a Natco process, parts are submerged in a quench bath during hardening.  A profile ground precision inductor is passed through each tooth while submerged.  The submerged process allows for consistent quenching while minimizing distortion.  This is the most distortion free induction hardening process we perform.  Automatic indexing produces identical hardness patterns from tooth to tooth and gear to gear.

"Hairpin" Induction Hardening
(Back To The Top)

Hairpin hardening is an excellent option when gear sizes make it impossible to employ the above methods.  Fine pitch gears ranging in size from 12DP-16DP are often hardened this way.  This method produces a through hardened tooth to below the pitch line.  When the gear application is wear only and there is no torque being applied, the hairpin method has been a
fine alternative to many gear manufacturers.

Production Runs Of Any Lot Size
(Back To The Top)

In addition to our gear hardening services, we also offer a wide variety of other induction options.  Whether it is pins, shafts, or other induction applications, we are capable of handling production runs of any lot size. As a job shop, we process orders from one piece on up.  Our in house machine shop provides quick tooling for any production run.
