High speed tapping atta<strong>ch</strong>ments with automatic reversal for<br />
CNC ma<strong>ch</strong>ines with straight shank<br />
These tapping atta<strong>ch</strong>ments are of extremely compact build. The stop arm prevents any rotation<br />
in the tool magazine and serves as a torque bar when the head is loaded in the ma<strong>ch</strong>ine spindle.<br />
According to the motto “FAST AND SIMPLE TO INSTALL”, TAPMATIC is maintaining a list with<br />
stop arms, whi<strong>ch</strong> have already been manufactured. By informing us about the ma<strong>ch</strong>ine type and<br />
serial number (please complete the customer inquiry form on page 34), we will be able to supply<br />
you with a quotation and principle drawing at short notice.<br />

CNC tapping atta<strong>ch</strong>ment RDT and RDT/IC are supplied as standard without stop arms.<br />
Depending upon the centre distance (see L3 above, centre of the ma<strong>ch</strong>ine spindle to the centre<br />
of the stop pin) stop arm assemblies are available with a 55mm, 60mm or 80mm centre distance.<br />
They are atta<strong>ch</strong>ed to the tapping atta<strong>ch</strong>ment via 4 fixing bolts. Other distances are obtainable by<br />
using spacers.<br />
