Optimized gear manufacturing

The purpose of production activity is to create added value. This also applies to gear manufacturing, and added value creation is conducted through production control for the purpose of achieving QCD (quality, cost, volume and deadline), including everything from the procurement of raw materials such as round bars for cylindrical gears and squared timber for racks to the packaging and shipping of the final products, namely gears.

The production process required for gear manufacturing covers a lot of ground, but general examples which can be given include cutting of materials with cutting machines, processing of materials with lathes, cutting of cylindrical gear teeth with hobbing machines, cutting of rack teeth with rack panels, cutting of internal gear teeth with gear shapers, deburring, and blackening, etc. In gear manufacturing processes other than machining mentioned above are also used such as injection molding, sintering, rolling, and casting. Furthermore, polishing, tempering, surface processing, teeth shape measurement, and examination with 3D measurement devices are also components of production activity.

The same as other industries, whether they are made to stock or built to order, optimization of manufacturing by making improvements (Kaizen) is essential in gear manufacturing.
