1 New Product News No.1601E Semi- Cutting Applications Turning insert VI Breaker for Nickel based alloys Pat. No HS Coating AJ Coating Patent pending Patent pending For machining aircraft parts or power generation machine parts such as shafts, disks, etc. Achieves long tool life for machining Ni-based alloys! High-speed cutting (vc = 80m/min) improves machining efficiency! Lineup is 80 items!

2 Technology Features Newly developed coating and carbide base material with excellent high-temperature strength improves wear resistance. Newly developed chip breaker shape suppresses the flow of heat to the cutting edge to enable long tool life. Wide chip pocket breaker shape provides excellent chip evacuation. The combined effect of the above features suppresses temperature increases of cutting edges to enable high-performance machining. Original positive breaker shape suppresses the flow of heat to cutting edges. Wide chip pocket shape has good chip evacuation. Obtuse corner bearing surface is provided to achieve strong clamping. New positive breaker shape The new positive breaker shape which suppresses the flow of heat to cutting edges is an effective countermeasure against heat sagging even when machining Ni-based alloys and also extends tool life Conventional breaker VI breaker 700 or higher 700 or higher 0.1 mm Temperature( ) CAE analysis conditions Analysis mode: Two-dimensional analysis, Work = Inconel718(AG) vc = 40m/min, f = 0.2mm/rev. ap = 0.8mm Effectively suppresses heat flow to cutting edges Because VI-RCMM1204M0 and VI-RCMM1606M0 are for unstable machining (interrupted cutting), there for, the cutting edge has negative honing geometry. 2

4 Selecting the appropriate insert material type according to the machining conditions (For Ni-based alloys) Good chipping resistance when performing unstable machining such as mill scale machining, welded surface machining, etc. Mill scale machining, Light Interrupt Cutting Unstable cutting (interrupted cutting) Cutting speed vc (m/min) Enables high-speed cutting even for finishing! Machining performance improved with maximum vc of 80m/min! Employing a carbide base material and coating with excellent high-temperature strength enables the tools to cover a wide range from medium to high speed. The performance is particularly apparent when performing light cutting or finishing!

6 The diagrams and table data are examples of test results, and are not guaranteed values. Attentions on Safety 1. Attentions regarding handling (1)When removing the tool from the case(package), be careful not to drop it on your foot or drop it onto the tips of your bare fingers. (2)When actually setting the inserts, be careful not to touch the cutting flute directly with your bare hands. 2. Attentions regarding mounting (1)When preparing for use, be sure that the inserts are firmly mounted in place and that they are firmly mounted on the arbor, etc. (2)If abnormal chattering occurs during use, stop the machine immediately and remove the cause of the chattering. 3. Attentions during use (1)Before use, confirm the dimensions and direction of rotation of the tool and milling work material. (2)The numerical values in the standard cutting conditions table should be used as criteria when starting new work. The cutting conditions should be adjusted as appropriate when the cutting depth is large, the rigidity of the machine being used is low, or according to the conditions of the work material. (3)The inserts are made of a hard material. During use, they may break and fly off. In addition, cutting chips may also fly off. Since there is a danger of injury to workers, fire, or eye damage from such flying pieces, a safety cover should be installed and safety equipment such as safety glasses should be worn to create a safe environment for work. Do not use where there is a risk of fire or explosion. Do not use non-water-soluble cutting oils. Such oils may result in fire. (4)Do not use the tool for any purpose other than that for which it is intended, and do not modify it. Printed in JAPAN (ME-FT3) :FP
