Hollow BBT – Two Face Contact CNC Tool Holders

Stitch Overseas Private Limited offers the most innovative CNC Tool Holders from NT Tool Corporation, Japan for application in advanced cutting technologies. BBT-AHO is one of the most technologically advanced tool holder that generates high precision and influences the machining accuracy of machine tools to acquire better product quality with lesser cycle time. The holder is made lighter by hollowing out the shank which reduces load to the spindle resulting in improved energy efficiency. A BT50 holder reduces from 4 kg ? 2.8 kg. Two-face contact and ideal sustaining balance of taper and flange achieve remarkable increase of quality in surface finish. At higher rpm’s when the machine spindle expands with centrifugal force a better two-face contact is maintained resulting in enhanced productivity. Taper area of tool holder expands along spindle taper owing to being hollow. In addition flange face tightly contacts to the spindle and realizes precise attachment. Continuous contact between the taper and the end face prevents fretting – thus adding to spindle life.
