"New technologies permeate the manufacturing industry every day," said a Servotech spokesperson. "It is as difficult as it is important to remain up to date on the changes that occur. Most manufacturing cells can be maintained and optimized through the use of replacement parts, upgrades and accessories. Having a supply of effective replacement components along with a support system to implement them is essential to maintaining a viable business.
"The main components of a CNC manufacturing unit are: drive, controller, motor and cables. Obviously there are countless iterations and variances, some with more components and others with less. Feedback, is what makes automated manufacturing possible. The accuracy of the feedback dictates the accuracy of the machine. Encoders have seen a steady improvement in technology. As computers have evolved over the years, encoders have enjoyed parallel upgrades in technology. What used to be accomplished with analog signals, transistors and hall effect sensors, is more commonly replaced with digital components. Servotech, although primarily a servo motor refurbishment company, offers the ST-EP-DR-TR3 Heavy Duty Tru-Trac encoder and measuring wheel for general integrations, as well as replacement encoders that directly replace OEMs.
"Servotech can directly replace Sumtak, Tamagawa, Nemicon and Heidenhain encoders. Each encoder has its own unique line count and output. Even if the encoder is a rare model, with uncommon signals, its output can be reproduced by an updated replacement. Encoders used on Siemens and Fanuc machines can be replaced, and not on special order, but as commonly stocked units. In more specified applications generic encoders are available to replace smaller and lesser-known manufacturers. Allen-Bradley, Reliance and Electrocraft servos had special encoders made for them that utilized an absolute step voltage signal. That style of encoder has been unavailable for purchase because the original manufacturer stopped making them. Having the capacity to buy new encoders, especially for units that are skyrocketing in price because of limited availability, can make a big difference in cost savings and down time.
"Although not as obviously vital as encoders there are a slew of other noteworthy parts that can be replaced. Brake parts, especially new pads, for electrical holding brakes can be manufactured and many major manufacturers are stocked. Bearings, seals, connectors, thermistors, switches and gaskets go without saying but are readily available as a matter of simple maintenance. Cables can be purchased to replace ones that are being eaten away by corrosive cutting fluids. It is even possible to get new parts and assemblies custom made to fit older out dated assemblies. Accessible parts are pivotal to the compound task of keeping manufacturing units functioning. New and old technologies can and do co-exist to keep older machines running longer. Having access to the experience and knowledge that can implement replacements effectively is what makes the process cost effective.
