The MAAG SH1200 located at CITIC is used for cutting gears up to 12m diameter.


MAAGCut Control System with Drives & Motors




Machine modifications involved removing most of the worn & difficult to source mechanical and electrical parts and conversion to a CNC machine. The result is a reliable machine which can run for the next 10~15 years. We also added gear measuring.


CNC Design’s system includes:

  • MAAGCut Software for gear shaping
  • Siemens SINUMERIK ONE CNC system
  • SINAMICS S120 Drives & SIMOTICS Motors
  • Electrical Cabinets, Operator Console and Machine Wiring
  • New Ballscrews, gearboxes and torque motors.
  • New axis measuring linear scales.
  • Gear measuring probe.
  • Rotary scale for rotary table direct measurement.
  • Engineering, Installation, Commissioning, Training & Support

MAAG Gear cutting CNC operating software


CNC Design’s MAAGCut CNC operating software has been developed and proven on a large number of MAAG machines worldwide. It offers many significant improvements in machine set up and cutting, compared with the existing system. Utilising a CNC allows us to eliminate both the old electrical control system and also most of the interlinking gears and shafts. This greatly simplifies the machine and eliminates most of the difficult to get service items, ensuring your MAAG will be supported for many more years to come.

There is no need for detailed programming the CNC control for the MAAG machine as everything is parametrised by the operator based on gear geometry.

Conversion to CNC makes it easier to train new operators.

 

SINUMERIK ONE CNC System


The MAAGCut solution uses the latest Siemens CNC, SINUMERIK ONE, the flagship control in the Siemens CNC portfolio. SINAMICS S120 digital drives with SIMOTICS servo, spindle & torque motors are used for all axes including the cutting head. The SINUMERIK ONE includes an integrated S7-1500F Safety PLC which can control all machine auxiliary functions.

MAAGCut Features & Benefits

​

While not making any changes on the basic principle of gear generating as designed by the machine manufacturer, this retrofit will significantly reduce the complexity of the current machine set up and machine usability.


  • The cutting strategies and cutting programs are predefined in various cycles, which we have developed with the input of industry leaders using MAAG gear shapers. The actual CNC programming code is not required to be modified by the operator and is part of CNC Design Pty Ltd Intellectual Property.
  • Operation of this machine is simple. All process data are entered into setup or operation screens, it can then be recalled from memory, or entered new, when the same job is repeated.
  • Machining data can also be modified dynamically during machine operation. All information will be checked for correctness and a comprehensive operator guide and logical checks accompany these inputs
  • New features designed for simplifying the operator’s tasks for setup, cutting monitor and measuring are provided.


CLIENT FEEDBACK

​

It is gratifying that the stability and accuracy of the machine are very good, and our company has given high praise to this project.
