Servicing, Maintenance and Trouble shooting of CNC Machine Tools – Mechanical, Electrical and Electronics Aspects


Servicing, Maintenance and Trouble shooting of CNC Machine Tools – Mechanical, Electrical and Electronics Aspects

Date : 19 to 24 December, 2022   Location / Mode : Bengaluru


Last date for registration 12 December 2022
INTRODUCTION

CNC machines are real Mechatronic systems, having electrical and electronic circuits interacting with mechanical actuators/sub-systems. Diagnostics and root cause analysis is an important aspect of maintenance, which is most often ignored. Often the roots of a mechanical problem is in the electronics area and that of an electronic problem lies elsewhere. Thorough understanding of the various sub-systems, CNC machine circuit diagram, Ladder diagram, and CNC parameters is needed to find and fix the root cause to minimize MTTR (Mean Time To Repair) and effective planning of PMBF (Preventive Maintenance Before Failure) towards zero downtime.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing 6 days workshop on "Servicing, Maintenance and Troubleshooting of CNC Machine Tools – Mechanical, Electrical and Electronics Aspects" in Bangalore. The training will be based on a hybrid approach with group exercises on circuit diagram study and practical demonstrations in CNC machines and subsystems maintenance and troubleshooting.


  • Anatomy of CNC machines – Overview of various sub-systems of CNC Turning and Machining Centres.
  • A systematic approach to diagnostics and problem-solving.
  • Circuit Diagram study – Electrical and electronic circuits
  • Circuit Diagram study – Hydraulic, Lubrication, and Pneumatic subsystems
  • Maintenance aspects in CNC controllers
  • Typical problems in Electrical and Electronic sub-systems; Safety aspects; Alarm messages, Alarm History, and Operations History
  • Maintenance aspects of drives and encoder
  • CNC Parameters setting
  • Demo and Group exercises in electrical circuit diagram study
  • Demo of Do's and Don'ts in CNC controllers
  • Types and applications of Linear Motion guide ways – Mounting and alignment method
  • Types and applications of Ball screw – Mounting and alignment method
  • Assembly procedure of Ball screw and LM Guides
  • Ball screw alignment w.r.t LM Guides
  • Troubleshooting of ball screws & LM Guides
  • Bearing types & their application in Machine Tools
  • Spindle failure & reconditioning
  • Spindle bearing preloading
  • Preventive maintenance of spindles
  • Live demo of Spindle dismantling, testing, and assembly
  • National and International standards for determining Positional accuracy and Repeatability of machine tools
  • Test code for machine tools and test parameters for machine tool qualification
  • Accuracy aspects:
  • Measurement of Geometrical accuracies as per test chart
  • Measurement of Positioning Accuracy and Repeatability of axes
  • Measurement of Interpolation accuracy (ball bar)
  • Finish machining accuracy on IS/ISO test piece
  • Live Demo on:
    • Laser Calibration
    • Ball bar testing

After undergoing the program, the participants will be able to learn

  • How to carry out preventive and break-down maintenance of CNC machines
  • Identifying faults in various components of CNC machines
  • How to report faults correctly to the manufacturer
