Syn<strong>ch</strong>ro tapping <strong>ch</strong>ucks with micro-flex for CNC ma<strong>ch</strong>ines<br />
Syn<strong>ch</strong>ro <strong>ch</strong>ucks are being used extensively on CNC ma<strong>ch</strong>ines for rigid tapping. On today’s CNC<br />
ma<strong>ch</strong>ining centres, spindle rotation can be syn<strong>ch</strong>ronized with the spindle feed (Rigid Tapping).<br />
However, experience shows that small errors in syn<strong>ch</strong>ronization can occur. These differences are<br />
minimal, but lead to increased tool wear. Furthermore, there are differences between computed<br />
feed rate and actual. Any discrepancy at all increases tension/torque on the tap, reducing tap life<br />
and thread quality proportionally.<br />
The SYNCHROFLEX tap <strong>ch</strong>uck with its axial and radial MICRO-COMPENSATION eliminates these<br />
differences and supports a precise hole location.<br />
The results are<br />
n Increased tap life of 50% or more<br />
n Improved thread quality<br />
n Increased production due to less tap breakage<br />
n Fewer downtimes<br />
Syn<strong>ch</strong>roFlex tapping <strong>ch</strong>ucks with straight shank DIN 1835B+E<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 and 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 />
Application<br />
On CNC ma<strong>ch</strong>ining centres, CNC lathes with rigid tapping.<br />

Note: Straight shanks 16mm; 20mm; 1“ subject to model available on request. Extended units for SFT50/75/100 are also<br />
available. Please indicate measurement A (in line drawing) length required.<br />
When using internal coolant of more than 30 bars, we recommend the use of our balanced coolant system BCS. Add<br />
“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 />
When using Roll Form Taps the tapping <strong>ch</strong>uck’s capacity must be reduced by 25%.<br />
