YK2712 CNC DOUBLE-CUTTER STRAIGHT BEVEL GEAR GENERATOR
The YK2712 CNC double-cutter straight bevel gear generator is a newly developed product of Tianjin Machine Tool Co., Ltd. through its specialized technology and experience in building straight bevel gear cutting machines and spiral bevel gear cutting machines for nearly 70 years.
The machine is designed for rough cutting or finish cutting straight bevel gears and it’s especially suitable for cutting gears with crowned teeth. The machining efficiency is very high, about 3 – 5 times higher than machines of the same specifications, and the machine noise level is low. The machining accuracy of the machine can reach Grade 6 of the GB Standard.
The machine is suitable for cutting straight bevel gears used in gear boxes, speed reducers, precision transmissions, etc.
MACHINE FEATURES
1. A GSK218MC-V CNC control system or a SIEMENS control system (Optional) a FANUC control system (Optional) is equipped on the machine and this is a 4-axis CNC machine with 3- axis simultaneous movements. A spindle servo motor controls the stepless speed regulation of the cutter spindle. Tool setting and cutter adjustments can be performed through the electronic handwheel.
2. The structural layout of the double cutter brackets is unique to guarantee a reasonable space in the high rigidity conditions of the machine.
3. Both the cradle and the workhead are driven by means of high precision worm and worm wheel pairs. All the structures ａnd the transmissions of the machine are rigidly designed.
4. All the CNC control system, the major electrical components, the bearings and the sealing parts are imported ones to ensure the reliability of the machine.
5. The machine has a free-standing sealed electrical cabinet equipped with a thermostatic-control device.
6. A full- enclosure is equipped for the machine.
7. A chip conveyor (Optional) is available for the machine.
