My-T Grooving System f2TT Application detail Comparison of surface roughness (conventional tool vs. GT insert) because the tip of GT-type insert slightly tilts during machining and acts like a wiper cutting edge it can produce a better surface finish than when using a conventional insert. f (mm/rev) f (mm/rev) Machining of various grooves When machining a constricted portion of a cylindrical workpiece choose the suitable method depending on the width and depth of the groove to be machined. 0.1 (back) 1 L shallow wide groove Chamfering and rounding-off at bottom corner of groove When chamfering or rounding-off at the bottom corner of a groove the procedures shown in the figure at the right are recommended. (D Method of finishing double-sided walls When finishing both sides of a groove by using GT-type inserts retract feed mode should be avoided. You should machine both side walls by plunging and then machine the bottom of the groove by traversing the tool. - 1 fT 1 L j V TAC Parting Grooving Tools
