there is a huge reduction in complexity and the resulting need for muscle and dexterity to achieve a tight fi t.
According to Dan, “An operator previously using a side- lock holder had to fi rst grind the Weldon fl at on the tool, and then assemble both through a process of touch and feel. Now operators are able to quickly learn the Haimer shrink-fi t system and replace the tool exactly the same every time, in just seconds.” Haimer states that the shrink-fi t holders
Using the Haimer shrink-fi t system, Skills Inc. saw a 30% increase in metal removal rate (MRR) and a decrease in the scrap rate from 7% to less than 3%.
This is what power, precision,
and innovation looks like. Over fifty years in the industry and 7,000+ items to show
have a precision bore which results in less than 0.00012" (0.003-mm) runout. Since there are no set screws, collets or nuts, balance is highly repeatable, resulting in in- creased tool life and surface fi nish. It has the highest gripping torque of any holder and will shrink both carbide and HSS cutting tools with changes of less than fi ve seconds on average. The tapered design provides the ultimate in rigidity and since there are no moving parts, the toolholder clamps the same way each time.

At Skills Inc. the transformation to the shrink-fi t system was fast since the Haimer product was signifi cantly easier to learn and put into operation than previous toolholding systems. Setscrews, torque wrenches for collet chucks, grinding for setscrews and whistle notches and the time- consuming training were all eliminated overnight. Without the complexity and number of steps to be implemented, more employees were able to move into the operator posi- tion with great success, which helps to satisfy the social bottom line. This was just the beginning of the benefi ts Skills Inc. enjoyed with the Haimer products. On the fi nancial side, a reduction in tool overhang pro- duced a 30% increase in metal removal rate (MRR). Cut- ting tools that once had to be replaced after machining one part now lasted for four—4× increase in tool life. More than 1½ hours of benching and manual reworking per part were saved due to the elimination of tool-related chatter. This step alone created approximately $2700 in savings for every 20 parts. Additional savings in time and material was achieved when the scrap rate dropped from 7% to less than 3%. Not only did the increased reach capabilities remove the
chatter, jobs previously done on a four-axis CNC machine were able to be moved to a fi ve-axis, reducing the cycle time from 15 to 2.5 hours and from eight operations to two. The resulting time savings allowed Skills Inc. to eliminate excessive machining and handling at a tremendous cost
