Toolholding

BIG-PLUS BBT30 Basic Arbors

10/14/2019
BIG KAISER has added inch standard sizes for the U.S. market to the production of its BIG-PLUS BBT30 basic arbors (shell mill holders, endmill holders, shrink fit and blanks). The expansion allows for enhancements to the BBT30 program that satisfy demands specific to the North American market.

Asia Pacific to emerge as the largest market for toolholders in 2019

Global demand for toolholders, specifically arising from the automotive and defense and aerospace industries, will witness a relatively steady growth between 2018 and 2028, as predicted by a research 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.

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.
