Milling Squares for Wrench on Reamer Shank
A reamer of the type illustrated is necessarily rather long and cannot be accommodated on centres as a shorter piece would be. It is, therefore, passed through the hole in the spiral head spindle and is clamped in the chuck, while the wrench end is supported by the foot-stock centre.
An end mill is used and the work is fed vertically. To prevent longitudinal movement of table, the small clamping lever shown on the front of the saddle is set up. Where there are many pieces to be done, a more permanent method of fixing the table is by means of stops that fasten on to the V bearing at the bottom of the table and come against the side of the saddle.
