Features
■ Longitudinally arranged with oscillated cutter relieving and the radial feed of worktable is made on three rectangular guide ways. Machine bed, column, cutter head and table are with better rigidity in structure and driving;
■ Three axes are controlled simultaneously for the cutter spindle rotation, the worktable rotation and the radial feed of the worktable;
■ Driven by a spindle servo motor; stepless speed regulation and automatic changeover can be made;
■ The cutter spindle can be stopped automatically at the up position;
■ A large-diameter zero-degree worm and segmental zero-degree worm wheel transmission mechanism which applies a constant cutting force during the whole cutting process, is adopted for the cutter spindle movements;
■ A new type double-roller and tow-way relieving mechanism is adopted for carrying out an accurate, stable and low noise cutter relieving motion;
■ A tangent cutter relief is possible to prevent cutter interference;
■ A safety enclosure, which has an excellent visibility for the operating conditions and is easy to be operated, is equipped to prevent oil splash and an auto chip conveyor is provided;
■ An independent forced lubrication system is used for the cutter head and timed and quantitative lubrication is adopted for the other parts; a chip-flushing oil gun is equipped;
■ SIEMENS 828D is equipped and an air conditioner may be provided for the independent sealed electrical cabinet;
■ A large number of coolant is used for the cooling system and the machine bed is designed as a coolant tank for the timely heat dissipation and stable accuracy;
■ Timed and quantitative lubrication is adopted between work spindle and worktable in order to reduce the moment and prolong the service life of worm and worm wheel pair;
■ A separate hydraulic pump station is available for the quick return of oil and to prevent the oil from being mixed;
■ Equipped with a reducer on the servo motor of worktable rotation axis (Y-axis), which elevates the motor capacity;
■ A new-type cutter adapter have been adopted in the cutter head;
Application
GSM1250 B3 CNC Gear shaper designed mainly for the production of gear used on large-and-medium size speed reducers, wind-mill generating components, tractor, construction machinery, metallurgical machinery, machine tool, aircraft and textile industries, etc., suitable for jobbing and batch productions and mass production, mainly used for cutting internal and external cylindrical gears, different kinds of non-circular gears and plate cams. When a helical guide and a special cutter are adopted, various kinds of serration couplings and involutes spline can be machined.
