Course information

This is a practical course aimed at companies, including Mills CNC customers, who have Heidenhain-controlled Doosan machining centres or similar Heidenhain-controlled machines manufactured by other machine tool builders.

The course will appeal to companies who have an in-house Machine Tool Maintenance or Service Department and need to increase the skill levels of their employees, thus enabling them to plan and undertake systematic trouble-shooting and preventative mechanical maintenance on
Heidenhain-controlled machining centres.

To get the most from this course it is important that attendees have experience of a machine tool's mechanical operation and the CNC control's  systems and functions.

Specific course content includes:

  • Explanation of the Heidenhain Control system
  • Introduction to the machining centre and its 3 Axis layout and configuration
  • Understanding the tool change system and sequence
  • Ball-screw accuracy, checking backlash and rectifying issues
  • Undertaking axis realignment
  • Checking pallet-changer systems and their operation if applicable
  • Understanding spindle assembly including through-tool coolant operation and mechanism
  • Hydraulic and pneumatic mechanisms
  • Operation, fault-finding and preventative maintenance

This course can occasionally be run at the Mills Mills CNC Training Academy's facility in Leamington (depending on a availability) or can be held at a customer's facility. (Charges will be different to above.)

This course is practical with some theoretical and classroom instruction. Training on a Heidenhain-controlled machine depends on availability, but the same principles may apply to other makes of controls.

If training is required at a customer's facility, it is important that attendees have a machine in a good working order available and not in a production situation.

A room with a projector & whiteboard available would also be beneficial.

If a machine has a fault before training commences, we will not undertake a repair on it, and the course may be cancelled with no refund given.

To find out more about this course call the Mills Mills CNC Training Academy on 01926 438363.

Safety Shoes and other P.P.E. Equipment is required.

Should you not have the appropriate Safety Shoes, training can not be given and no refund will be offered.
