Main Characteristics of BG300DC CNC Double-cutter Straight Bevel Gear Generator
1. A SIEMENS 828D CNC control system 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 condition of the machine;
3. Both the cradle and the workhead are driven by means of high precision worm and worm wheel pairs. All the structure and the transmission 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 thermo-control device;
An enclosure and an auto chip conveyor are equipped on the machine;
Applications of BG300DC CNC Double-cutter Straight Bevel Gear Generator
BG300DC CNC Double-cutter straight bevel gear generator 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.
BG300DC CNC Double-cutter straight bevel gear generator is suitable for cutting straight bevel gears used in gear boxes, speed reducers, precision transmissions, etc., and also for cutting differential gears used on the rear axles of luxury cars.
