Effective Maintenance of CNC Machines – Mechanical Aspects

Training Programme on

Effective Maintenance of CNC Machines  –  Mechanical Aspects

21-22 April 2016: Pune

Mechanical Maintenance in Industry gets somehow done under duress, hence a systematic approach for diagnosis and resolving problems cannot be followed. Systematic hands on experience on Maintenance techniques is neither given at education institutions nor is it generally possible in day-to-day working in the industry. Ultimately it results into lesser than expected performance of machines, erosion of equipment reliability and dependability.


Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) had organized a 2 day Training Programme on Effective Maintenance of CNC Machines - Mechanical Aspects on 21 - 22 April 2016 at IMTMA Technology Centre in Pune. Programme was focused on providing hands on experience for systematically approaching the common problems in CNC machines and its subsystems.

The training programme focused on :

  • Maintenance Management: Breakdown Maintenance, Preventive Maintenance, Predictive, Spares planning and Safety while doing Maintenance
  • Anatomy of VMC and CNC Lathe.
  • Do's and Don'ts of mechanical maintenance, tricks of trade.
  • Demo for Leveling, Orthogonality, Spindle Run-out, play, backlash and Calibration Checking.
  • Maintenance of Machine Subsystems such as Hydraulics & Pneumatic Circuits, Lubrication System, Cutter Locking and ATC.

This programme was conducted by Mr. Avinash Khare, Mr. Ashok C S Raj along with industry experts from Setco Spindles India and Renishaw Metrology System.

Delegates from Phoenix Mecano India, Endurance Technologies. Indo Toolings, L.G Balakrishnan & Bros, Gea Westfalia Separator India, SKF India, Nuclear Fuel Complex, Kirloskar Pneumatic Company, Ferromatik Milacron India, Quality Gears, and Bharat Forge attended the training programme.

Manufacturing Excellence through SPC and Problem Solving Tools

Manufacturing Excellence through SPC and Problem Solving Tools


Variation in any manufacturing process is inevitable but needs to be controlled. If external or assignable causes of variations are excluded, the natural causes are restricted to a combination of variations due to machines, tools, methods, materials and people who work at the workplace. Statistical Process Control (SPC) is a technique to enable measurement and analysis of the variations at the workplace and try and control the same at optimum levels. While SPC techniques involve extensive use of various types of control charts, an understanding of all the basic seven quality tools helps in a better understanding and implementation of SPC. Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a 2 day programme on Manufacturing Excellence thro SPC and Problem Solving Tools on 28 - 29 January 2016 at Pune.

The programme primarily focused on :

  • Measures of central tendency and spread 
  • Types of frequency distributions 
  • Evaluation of discrete data and grouped data (through example) 
  • Concepts of probability 
  • Statistical decision making 
  • Acceptance sampling (sampling plans) 


Objectives and benefits of SPC

Strategies for Successful Design and Processing of Plastic Parts


We are said to be living in an era of Plastics since 1974, as the world consumption of plastics from that year onward exceeded that of steel by volume! From household appliances to airplanes, from tooth brushes to telephones, from Computers to cars, everything seems to be made out of plastics these days. The reasons are not far to seek. Injection molded plastic parts offer unbeatable combination of Light Weight Construction, Flexibility, Toughness, Chemical Resistance, Long-term Performance and Cost Effectiveness. World Class Injection Moldings are a result of Knowledge of Plastics, Excellent Part Design, Robust Mold Design, Methodical Mold Manufacture, Optimum Process Parameters and Reliable Molding Machine.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organized a 2 day programme on Design and Processing of Plastic Parts on 22 - 23 December 2015 at Pune.

The programme primarily focused on :

  • Introduction to Plastic Materials, Properties and Applications.
  • Injection Moulding Process, Machine and Mould Construction.
  • Plastics - Manufacturing Processes.
  • Design of part features such as wall thickness, radii, ribs, boss, snaps, threads, draft, parting line, holes and undercuts.
  • Design with respect to manufacturing such as part integration, gate location, shrinkage, and mismatch, ease of manufacturing, stiffness and tolerance.
  • Counter Measures w.r.t Moldflow Observation.
  • Finishing of Plastic Parts.
  • Assembly Techniques of Plastic Parts.
  • Defects and Remedies.


The seminar was conducted by industry experts from NTTF. Delegates from Brose India Automotive Systems, Bajaj Auto, Behr-Hella Thermocontrol India, Blue Star, Bosch Chassis Systems India, Brakes India, Dr. Wiesner Test & Automation, Elephant Design, Fiat India Automobiles, Fine Handling & Automation, Fleetguard Filters, John Deere India, Larsen & Toubro, Mahindra Two Wheelers, MSC Software Corporation India, Shapers India, Siemens, TVS Motors, and Valeo India attended the seminar.

Latest Trends in PDC Dies & Plastic Mould Manufacturing

Latest Trends in PDC Dies & Plastic Mould Manufacturing


Changing customer expectations and rapid model changes requires a fast turnaround in the manufacture of Dies & Moulds. Presently, production demands require the ability to react to frequent product changes, shorter production runs, lower inventory levels and higher productivity.

To meet these challenges a host of new technologies have evolved over the years. Apart from the conventional technologies like Die sinking & Wire EDMs the new generation manufacturing extensively uses hard machining and complex profiling on multi axis machining centres to completely finish the die and mould with little need for manual finishing and correction. Supporting these machining methods are new developments in design analysis, inspection techniques and complex programming systems.



Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) organised a 2 day programme on Latest trends in PDC Dies & Plastic Mould Manufacturing on 24 - 25 February 2016 at IMTMA Technology Centre in Pune.
