The number in bold font is recommended starting conditions. Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation. Dry machining is recommended. How to mount an insert 1 . Completely eliminate chips and dust from the insert mounting side. 2. After mounting a clamp screw on the top edge of wrench, tighten the screw while keeping the insert pushed against the shim seat surface and holder surface (Fig.1,2) 3. Make sure that the identification on the top of the insert is the same in each pocket.(Fig.3) 4. Tighten the wrench (TTP-20) in while holding parallel to the clamp screw. M 5. Tighten the insert clamp screw at an appropriate torque. (Recommended torque: 6.0 N·m) 6. After tightening, check that there is no gap between the insert and the surface of the shim, or between the side surface of insert and the holder surface. If there is a gap, remount the insert using the directions above. Shim seat surface Wrench (TTP-20) Milling Constraint surface Clamp screw Fig.1 Fig.2 Fig.3 How to replace a shim 1. Completely eliminate chips and dust from the shim mounting side. 2. Coat medium strength screw locking adhesive on the screws. 3. Tighten the screw keeping the shim pushed against the pocket surface of toolholder. 4. After tightening both screws temporarily, tighten them with appropriate torque. (Recommended torque:3.5 N·m) Perform temporarily tightening and tightening in the order of (1) and (2) (See Figs. 2 and 3). 5. Please check that there is no gap between the shim and the pocket surfaces of toolholder. Pocket surface of toolholder Wrench (DTM-15) Pocket surface of toolholder Fig.1 (1) Fig.2 (2) Fig.3 Fig.4 M47
