Gear hobbing is an essential gear manufacturing technique and can process parts of different desired precision levels through rough hobbing, finish hobbing, and skiving.
Skiving based on carbide hobs is 5-6 times more efficient than traditional cone tools and helps improve machining precision. The quality of this machining's outcome can influence other necessary grinding processes such as gear grinding and gear honing. The hob makes consecutive cuts on the gear blank to create gear teeth. During the process, the gear blank and the hob must be synchronized in the rotation to create precise cuts. It can be used for gear cutting, spline cutting, and sprocket cutting.
Hobbing shows characteristics of high flexibility and is applicable for producing any amounts of teeth, various profiles, and helix angles. It also shapes gear teeth patterns on an outer diameter productively and economically. There are two basic grinding techniques: form grinding (non-generating) and generating grinding. In form grinding (non-generating), a disc wheel grinds the space between two gear teeth or splines, and an involute attached to the wheel guides the grinding process. The generating grinding technique is straight-sided, and the workpiece moves along the abrasive tool to form the splines. After the gear teeth or splines are created, more refined grinding might be necessary for polishing and smoothing out the surface of the gear or the shaft. Once finished, the gear or the motor shaft is ready for action.
Wen-Hsiang adopts a generating grinding approach and utilizes Koepfer 200 Gear Hobber. Our machining process is automatic; the machining capabilities include gear hobbing, soft and hard machining, skiving, high speed hobbing, radial hobbing, and tangential hobbing. Our finish hobbing and skiving services through LIEBHERR-LGG180 can provide high precision machining for heat-treated metals and are available for gears, motor shafts, and other metal parts for high precision machinery and equipment.
Our gear hobbing process is automatic and is capable of conducting various processing procedures, includes gear hobbing, soft and hard cutting, skiving, high-speed gear hobbing, radial gear hobbing, and tangential gear hobbing. Skiving requires the gear hobber to have good rigidity and high precision. Only with the correct integration of gear cutting technology, gear hobbing tools, and machine tools can the gear hobbing achieves the best result, and skiving can reach the optimal precision level. Our skiving service is suitable for processing hardened metal workpieces and high-speed and high-precision gears. When processing small gears such as pinion gears, our skiving service can achieve excellent and stable machining accuracy.
