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.
also lowering cost per part. Vickers then passes these savings on to its customers in the form of competitive job pricing. Matt Tyler, president and CEO, along with his manufactur- ing team at Vickers, agree the shop has and continues to achieve amazing reductions in cycle times and increases in tool life. Longer tool life equates to fewer tool changes, and thus even shorter cycle times. Plus, any potential errors associated with tool changes, such as incorrectly entered offsets, are dramatically reduced for a signifi cant rise in overall process stabil- ity. Tyler and his manufacturing team also agree that many of those improve- ments would have proved impossible without the advanced tooling technol- ogy and expert application support from Seco Tools LLC (Troy, MI). Examples abound where a simple tooling switch or how altering an exist- ing tool was used to optimize machin- ing performance. In one instance, the shop made a slight programming change and was able to run a cutting tool 70 ipm (1778 mm/min) faster and take a 0.010" (0.25-mm) heavier chip load, slashing a whole minute off part processing time for an annual cost sav- ings of almost $70,000. For another job, Vickers simply went
from using coolant with a particular inserted cutter to running it dry. Once it did, the tool fed faster and harder by about 350 sfm (107 m/min) over previ- ous parameters, shaving 40 seconds from the overall cycle time. Tool life skyrocketed from 150 to 450 parts per insert index.
Other tooling successes involved a switch in insert grades that not only lopped 45 seconds off part cycle time for one job, but also boosted tool life by a factor of 2.5 times. In another, the shop implemented a multifunction tool that did the work of two individual tools to reduce tool changes, shorten cycle
