Toolholding

Proper toolholder torque setting goes off the charts

For years, collet-type toolholder assembly and setup have relied on cumbersome, error-prone manual methods that waste time and money. From a wall filled with adjustment charts, operators reference torque values based on specific collet series holders and tool diameters. Then they must locate the appropriate torque wrench, unlock it, set its torque level and re-lock it before tightening a toolholder’s collet retention nut. This complex procedure leaves many shops scrambling to regain precious lost production time – and often leads to inaccurate torque settings that can damage toolholders and, in some instances, impact workpiece precision negatively.

The importance of toolholder retention knobs

High-speed machining — in excess of 20,000 rpm — often is used in aerospace when machining exotic alloys and hard metals, such as titanium. At these speeds, precise, secure seating of tapered toolholders in the spindle becomes even more critical. Failing to pay attention to this single detail can lead to decreased productivity, less precise machining, reduced tool life and damaged workpieces.

Global toolholders market will top $1 billion by 2019

Global demand for toolholders, specifically arising from the automotive and defense and aerospace industries, will witness a relatively steady growth through 2028, as predicted by Future Market Insights (FMI) in its recently released market intelligence report. While the demand for toolholders will be largely driven by emerging economies, in particular the manufacturing sector, China is likely to make substantial investments in high-performance cutting tools, considering the robust manufacturing and industrial output in the region.
