Gear hobbing machine, gear hob used to generating method hobbing cylindrical spur gear, helical gear and spline, sprocket, etc. Can also adopt the method of manual radial feed to processing ordinary worm gear. Order according to the user's requirements, special parts, using tangential feed hobbing worm gear.
The machine is suitable for single piece and small batch or batch production gear processing. The main electric, hydraulic components adopt domestic famous brand products.In the key casting lathe bed, column, etc by double deck wall, high stiffened plate structure, its structure is compact, dynamic and static stiffness, high accuracy. Machine adopts the workspace half seal shield, not oil, eliminate roll teeth when the permeability, oil spill pollution to the production environment.Strong rigidity, machine tool working accuracy stable, easy to operate.Machine can press down milling or conventional milling work. Machine with automatic stop mechanism, safety equipment and automatic lubrication system, according to the precision of gear hobbing machine test GB/T8064-1998 standard test factory. According to machining big modulus gear, small, can feed, for once or several times in the double class A hob, by processing the workpiece materials, process operating rules under the condition of reasonable, its finishing precision can achieve GB/T10095-2001 of involute cylindrical gear precision accuracy level 7.

Base on workbench institutions by the workbench, spindle unit.Workbench including: stop, inching and variable speed function.The workbench to withstand vertical load. Machine tool under the condition of environment temperature 0 to 40 degrees can work normally.
The hob holder is used to support the hob main shaft and drive the hob mounted on the main shaft to make vertical feed motion. The internal bearing adopts domestic famous or imported bearings with long life.


The gear is selected from domestic high-quality suppliers, such as SMTCL or other well-known manufacturers. In addition, the combination of different hanging wheels will achieve the purpose of rolling out different gear forms.
The main electrical components inside the electrical cabinet are from well-known domestic manufacturers. At the same time, we also provide accessories similar to Siemens and Schneide r. The specific configuration requirements are determined by the customer.


Operating the handle, different handles can achieve different speeds, the specific speed is related to the size of the machine.
