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.
