Before carrying out the work without operator, be sure to remove the chips and confirm the safe condition for cutting. 2. The steel chips may cause cuts, burns or damages to eyes. Be sure to install the safety cover around the tool and wear the safety glasses when carrying out any works. 3. Replace the insert in good time to avoid any breakage of the tools because of wear and tear. Points requiring care when creating the machining program Define the tool as the shape of the R2.0 radius. Use with axial-direction cutting depths ap of 1.2mm or less. Corner R definition in CAM Remainder Over Cut R R R Remainder Corner R definition in CAM 07

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.
