3 Axis CNC Bevel Gear Generator For Spiral Bevel gear , Cutter Diameter 6″ , 9″ , 12″

Quick Detail:

This is a new type of CNC machine developed on the base of YT2250 Spiral Bevel Gear Generator.

It is used to cut the gears from the small one of 25 mm in diameter and 2.5 mm in module up

to the large one of 500 mm in diameter and 10 mm in module. The machine is designed for roughing and finishing Spiral Bevel Gears, Hypoid Gears, Angular Bevel Gears, Pinions which are meshed with non-generated gears and gears with long cone distance used in automobile, construction machinery, aviation and machine tool industries. It is most suitable for batch production as well as suitable for mass or jobbing production.

Description:

1)The machine is designed to operate as a three-axes CNC control Spiral Bevel Gear Generator, i.e. cradle oscillation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis) being simultaneously controlled by control system for cutting the gears. The rotation of cutter spindle is controlled by a frequency variable motor for its stepless control.
2)There are no any change gears on the machine for easy operation, variety application and minimizing the setting time of machine. The machine settings calculated for YT2250 or Y225 machine can be converted into the relative machine settings of YKT2250 machine.
3)When setting the cutter by hand, the power of main motor will be off, so as to protect the operation. Three axes(X, Y and Z) will be back to zero positions through switches for ensuring the high accuracy and there are forward and backward limit switches for Z axis.
4)A high precision worm gear set is used for cradle drive and work spindle drive respectively, which are controlled by AC servo system for getting high machining accuracy. The machine is with higher structural and driving rigidities.
5)The machine is equipped will CNC control system 802D (SIEMENS), AC digital servo system and frequency variable regulator to accomplish the automatic or manual control and fault defect.
6)The machine is equipped with an independent sealed electrical cabinet, which is with air conditioner or thermo exchanger.
7)Safety guards and auto-chip conveyor can be provided on the machine.
