Product Details

YK2280 CE cnc gear milling machine

Main Features

Such cnc bevel gear milling machine has following features:

An A. C. frequency-variable motor is used as main driving power source while the cradle rotation and work spindle rotation are driven by the servo motors. The sliding base movement is driven by a servo motor through a ball screw. All of these features of the machine are for purpose of simplifying the conventional mechanical structure, reducing the machine setup time and shortening the transmission train because of the change gears elimination. In the case, not only the machine accuracy is increased, but also the operation is easy and convenient. Safety guards and an automatically chip conveyor may be provided on the machine. The machine is equipped with a sealed.

Main Usage

Applications of Machine

Model YKD2280 machine is a precision CNC Spiral Bevel Gear Generator, which is designed for roughing and finishing Spiral Bevel Gear and Hypoid Gears and Constant-depth gears of the Gleason system with the diameter up to 800mm and module 15mm.

On this machine, the cutter is mounted on the cradle (circular guideway). The integral structure is rigid, highly accurate and working stably. The cradle-type gear cutting machine, which is also possible for heard surfacing, is durable and the service life will be several dozens of years normal operating conditions. The machine is with universal features and it is suitable for roughing and finishing, in mass production, gears used for medium & heavy load trucks, mining machineries, construction machineries shipbuilding industry.

The machine is equipped with a CNC control system 802DSL(SIEMENS) and designed to operate as a three-axis machine, i.e. cradle rotation(X axis), work spindle rotation(Y axis) and sliding base movement(Z axis)being simultaneously controlled by the CNC control system to cut gears. The rotation of cutter spindle(S axis)is controlled by A.C. frequency-variable motor for its stepless control. Therefore, no change gears will be used on the machine for cutting gears. The machine operation is easy and flexible. The clients who have the conventional machines can convert the machine settings used machines into the machine settings for the YKD2280 machine.
