High Efficiency Finishing Special Shape Tool Series GALLEA series Added corner-connected R insert for GP1LB that easy to use for 3-axis machining. Mitsubishi Hitachi Tool Engiijjgeijiijj

GP1LB Combination of lens tool and barrel tool Concept of GALLEA series Comparison of barrel tool and ball-radius end mill Barrel tool Corner radius end mill Cusp height Cusp height Cusp height When contour milling with the same theoretical cusp height, the barrel tool can be machined with a pitch of about 1.7 times compared with the ball end mill of the same diameter, and about 3 times as compared with the R3 radius end mill. Comparison of lens tool and ball end mill Lens tool Cusp height Can be machined with pitch of about 1.4 times compared with the ball end mill of same diameter. Because...

3-edge, curved surface cutting GF3L Seamless High efficiency for 5-axis machining The same R size GALLEA series as φ60 ball end mill. φ60 Ball End Mill Offset the tool radius difference. 20 Usable range of barrel egde. Usable range of barrel edge. Usable range of lens edge. How can finishing time be reduced? Conventional pitch and cusp height Large pitch! Small cusp! Pitch of GALLEA series Possible to reduce the polishing time in case of same pitch conditio
