THREAD MILLS – NUMBER OF PASSES TABLE

How to use the tables to find the depth increments per pass: 1. Select the table for your thread profile (example: “M12“ is a metric thread). 2. Find the column matching your thread pitch in the top row of the table. 3. Find in that column below the recommended number of passes and for each pass the increment radial depth of cut. (example: for a pitch of 1.75 the recommended number of passes is 5 and radial depth of the 1st pass is 0.277 mm, the 2nd 0.228 mm etc.). 4. It is recommended to increase the number of passes for more difficult to machine materials. 1 5. For super-finishing result it is best practice to repeat the final pass.
