Parting-Off Grooving & Grooving Tool Holders GND Type GND Series Expansion for Small Lathes Supplementing the holder program with the cross-section 1010, 1212, 1616, 2020 and 2525. The line up includes grooving widths of 1,25mm, 1,5mm, 2,0mm and 3,0mm. Reduces chattering and achieves high-efficiency machining Reducing vibration during grooving by employing the same high-rigidity holder design of the GND w=2,0mm series. w=1,5mm w=1,25mm Low Cutting Resistance Chipbreaker GF Type Reduces chip control problems The GF type chipbreaker is added to the current wide selection of chipbreakers to improve chip control un- Chip control with point contact der various conditions. Reduces chattering during cutting Ideal for machining using low-powered equipment such as small lathes Reduces adhesion to tools and achieves long tool life in machining of stainless steel, etc. Achieves excellent chip control and reduced cutting resistance due to the sharp cutting edge design with a 30° rake angle as well as Sharp cutting edge design the reduction of frictional resistance through chip control with point with a 30° rake angle contact. Minimum Groove Width: 1,25mm Effective for reduction of material costs and for reduction of vibration during cutting off. Provides Excellent Surface Finish and Chip Control Work Material: 15CrMo5, Ø22mm Holder: GNDL R1212JX 1,2512 Insert: GCM N125005GF (AC530U) Cutting Conditions: n=2000min-1, f=0,03mm/rev, wet GND (GF) Type Competitor‘s Product Application Examples Principal Force Back Force 1.000 800 831 Stable and Reduced Vibration Large Vibration 600 713 751 593 400 382 408 200 0 GF Type Conventional Grade Competitor‘s Product GF Type Competitor‘s Product General Purpose Type Low Cutting Force Type Low Cutting Force Type Work Material: C54, Ø30mm, cut off applications Work Material: C54, Ø30mm, cut off applications Holder: GNDL R2525M 320 Holder: GNDL R2525M 320 Insert: GCM N3002GF (AC530U) Insert: GCM N3002GF (AC530U) Cutting Conditions: vc=80m/min, f=0,10mm/rev, wet Cutting Conditions: vc=80m/min, f=0,10mm/rev, wet F3 Cutting Resistance (N) Cutting SurfaceChip
