When Dan Olson joined Skills Inc. as plant manager of manufacturing in 2012, the company was using a hodge-podge of extended length tools held by milling chucks, collet chucks, and side-lock toolholders. The skilled operators were turning


out a quality product, but it was slow, took a lot of effort and produced a lot of chatter and scrapped pieces. Dan knew the only way to get rid of the chatter and pick up some speed was to make a change in toolholders.


GRINDING’S PERFECT PAIRING


SMARTER WORKHOLDING


Precision shaft grinding applications demand attention to detail. Our AcuGrind Air Chucks deliver single-micron repeatability part after part. Pair them with our easily adjustable SRG Grinding Steady Rests, and you’ll have a setup capable of ultra-high precision, worry free grinding. For maximum efficiency, SMW’s unique quick reset feature easily resets back to zero in seconds with consistent and predictable repeatability.


At SMW Autoblok, we have dozens of ways for you to hold workpieces better, stronger and smarter. Call or visit our website to learn more.


One of the reasons Skills Inc. is so successful is its willingness to invest in new technology. In fact, due to its non- profi t status, most of its earnings must be reinvested in the company. So when an opportunity to improve productivity comes along through the use of a supe- rior product, implementation is rapid. Within two weeks of arriving, Dan


had removed the old toolholding sys- tems from 24 machines (a mixture of vertical machining centers and tool- room mills) and standardized the entire manufacturing plant with Haimer’s shrink-fi t toolholders and Power Clamp Economic Plus shrink-fi t machines. Having used Haimer shrink-fit toolholding systems for years in a for- mer position,Dan knew firsthand that they were easy to use, allowed for fast tool changes and had excellent balancing capabilities.


After a demonstration in the Haimer

product van and the installation of a sample on-site, the operators were more than happy to abandon the collection of side-locks and collets they had been using and switch over to shrink-fi t. The operators soon found out for themselves that the Haimer shrink-fi t system was easy to use and had great repeatability. It is the only high-torque toolholder system that is so simple that tools can be changed with one hand. Other mechanical formats take two hands and lots of muscle to tighten the clamping mechanism.


Unlike mechanical holders, the


shrink-fi t system uses heating and cooling cycles that clamp the tool in the holder with incredible rigidity. Since the shrink-fi t system is thermal,
