We are offering hydraulic expanding gear hobbing fixture with auxiliary sleeve (for splined id component) (2). Hobbing mandrel-tailstocktop actuated in this type centring of component and face clamping is performed simultaneously when the tailstock side is actuated. The clamping piston is actuated with a pin at the centre of tailstock. Face run out compensation can be provided with the help of floating attachment of tailstock side flange. hobbing mandrel-drawbar actuated in case of draw bar actuated type hobbing fixture the piston is actuated with the help of machine draw bar. For components having sufficient clamping length and root diameter closer to the bore it is possible to obtain the entire torque via. Radial clamping. Multiple clamping is also possible.

We are offering hydraulic expanding gear shaving mandrels (auto actuated). Between centre auto actuated shaving mandrel between centre hydraulic gear shaving mandrels can be manual or auto actuation type. In this type work piece loading is done outside the machine. The work piece is loaded on one half, and then the second half is engaged. in case of manual actuation gear clamping is done manually on one half outside the machine. In auto actuation type after engaging component on one half and the second half of the mandrel, the complete assembly is placed between centres on machine and centring and clamping is performed simultaneously via. Axial pressure of tailstock against gear face. the run out accuracy is below 0.005 mm. machine mounted auto actuated shaving mandrel in this type both halves of mandrel are mounted on opposite work piece spindles. These are suitable particularly for auto robotic loading. the clamping and centring of mandrel is performed same as in case of auto actuated between centre type. the run out accuracy is 0.003mm.
