Syn<strong>ch</strong>roFlex tapping <strong>ch</strong>ucks with HSK shank<br />
Tapping <strong>ch</strong>uck with MICRO-COMPENSATION (max. ±0.5mm). To eliminate radial and axial feed<br />
discrepancy in the CNC ma<strong>ch</strong>ines programmed feed/speed (rigid tapping).<br />
Features<br />
n Computer generated Flexure for cushioning (radial and axial)<br />
n The Flexure eliminates pressure on the tap, thereby perfect threads and up to double tap life<br />
n Right hand and left hand tapping<br />
n Steel collets ER-GB, inter<strong>ch</strong>angeable shanks<br />
n Predictable tapping behaviour throughout the entire life of the tool<br />
n Outstanding results with standard taps<br />
n Internal coolant system up to 30 bar (version S for up to 80 bar)<br />
n Integrated short design<br />
Application<br />
On CNC ma<strong>ch</strong>ining centres, CNC lathes with rigid tapping.<br />
Delivery<br />
Standard nut and wren<strong>ch</strong> are included in the delivery.<br />

Note: When using internal coolant of more than 30 bars, we recommend the use of our balanced coolant system BCS.<br />
Add “S” to the article number and you will receive the S-model with IC-nut. For minimum quantity lubricant MMS add<br />
“M” to the article number. Sealing gaskets are ordered separately.<br />
The models SFT50 and SFT75 can be supplied with QC spindles. Add “QC” to the article number. Shrink-fit is also<br />
available on request.<br />
Extended units are also available please indicate measurement A (in line drawing) length required.<br />
When using Roll Form Taps the <strong>ch</strong>uck’s tapping capacity must be reduced by 25%.<br />
