YKD2280 CNC Spiral Bevel Gear Generator

YKD2280 CNC SPIRAL BEVEL GEAR GENERATOR

Ⅰ. Applications of Machine

  Model YKD2280 machine is a precision CNC Spiral Bevel Gear Generator, which is designed for roughing and finishing Spiral Bevel Gears and Hypoid Gears and Equidepth 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 hard surfacing, is durable and the service life will be several dozens of years under 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 and shipbuilding industry.

  The machine is equipped with a CNC control system 828D (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 an 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 for YT2250 (or Y225) and Y2280 machines into the machine settings for the YKD2280 machine.

Ⅱ. Main Features of Machine        

  An A.C. frequency-variable motor is used as a 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 the purpose of simplifying the conventional mechanical structure, reducing the machine setup time and shortening the transmission train because of the change gears elimination.  In this case, not only the machine accuracy is increased, but also the operation is easy and convenient.  Safety guards and an automatical chip conveyor may be provided on the machine. The machine is equipped with a sealed electrical cabinet which is with an air conditioner.
