Stop Rod Selection - Seco EASYSHRINK EVO User Instructions

STOP ROD SELECTION

The stop rods enable:
▪ The depth of the tool inside a tool holder without back-up screw to be set
▪ The depth of the tool for twin tool holders for multi-spindle machines to be set
▪ Broken tools stuck inside a tool holder to be pulled out
NOTE
The stop rod is chosen by the LFNLF (= LPR - LSC) result and your value will correspond to a specific S Group.
When using finned support for Shrinkfit holder taper SA50 (ZFAD05S50), add 60 mm to the LFNLF value
obtained.
Example: Seco Tools tool holder type SFD 5403
We have previously determined that the shrinking depth LSC = 39 mm (1.54").
The gauge length LPR can be found by reading the specification or by measuring.
LFN-LF = LPR – LSC = 120 (4.72") – 39 (1.54") = 81 mm (3.18")
In this case, the suitable stop rod is the one in front of the S2.
