CNC Retrofit: Today’s need for machine tool industry

By OEM Update Editorial August 7, 2019 3:09 pm IST

A CNC retrofit upgrades the CNC, the servo motors, spindle motor and drives and a portion of the associated wiring and related electrical panel. It’s not like rebuilding and remanufacturing, a CNC retrofit does not include any major repairs to the machine mechanics. Retrofitting is replacing its CNC, servo and spindle systems by latest one. Assuming the machine tool is generally in good shape mechanically, keeping it updated with the latest CNC control technologies is typically the most cost-effective and economically sustainable solution to enhance its overall performance.

Why CNC retrofit?
CNC retrofitting is typically the low cost solution to improve the overall performance of an older CNC machines. CNC retrofitting of old machines with a new CNC control can quickly improveits productivity, reduces maintenance costs and extends machine life. The latest technology CNC controller improves machine accuracy, performance and ultimately produces quality products at low cycle time. This increases the productivity and can produce complex parts with easy operations and easy programing. The smart CNC controlled programing assistance reduces expert human CNC programmers. This reduces human errors in part programs and ultimately reduces machine accidents. Current digital drives incorporate advanced electronics that push electrical energy back into the line when decelerating the servo and spindle motors which reduce electricity costs by 30 to 50 per cent. Recently, CNC controllers are delivered with servo tuning feature to ensure stable operation for a wide range of applications with better finished products. The availability of spare parts of old CNC are very difficult as compared to recent CNCs. The standardisation of CNC controller at specific brand ensures easy spare management.Technical support may be not available for your older CNC. Even if the original manufacturer is still in business, they may not have resources available that are experienced with your particular control vintage.
