X <strong>Threading</strong> Technical Data Step by Step Thread Turning - Example 2 5-6ACME-3G Application: Thread: Internal Right Hand ACME Pitch: 6 tpi Bore dia: 5” Material: Stainless Steel Austemitic 1 Choose the Thread Turning Method (see page 121) To facilitate the removal of chips from the machined area, we chose a feed direction away from the chuck. Therefore an internal left hand insert and an internal left hand toolholder are to be used. 2 Choose the Insert Size (see page 59) Y L IC Chosen insert: 4IL6ACME Insert Size Pitch Ordering Code IC L inch tpi RH Anvil LH 1/2” .87 6 4IL6ACME...

The reverse helix method is used. From the lower part of the table, using a pitch of 6 tpi and a bore diameter of 5”, we obtain a helix angle of -0.65°. 139
