My-T Grooving System Cautionary point in use Recommended tightening torque of the Place insert by hand into the pocket until clamp screw is 4 to 5 Nm. rear stop. 1. Place wrench into the specified hole of the blade and push it down. 2. Place insert by hand into the pocket until rear stop. 3. Push wrench upward until insert is firmly clamped. In traverse feed machining the tip of the tool can be elastically deformed. At extreme cutting conditions the diameter of the workpiece may exceed programmed dimensions. Dimensional compensation of the outer diameter as shown in the right diagram have to be taken into consideration when programming (example medium carbon steel). When face grooving the blade diameter should match the machinable diameter of the workpiece. The applicable blades are shown in this brochure. In the left figure D2 shows the machinable maximum diameter and D1 the machinable minimum diameter. This limitation only applies to grooving operations.
