Сверла Митсубиси по металлу Японский осевой режущий инструмент для сверления отверстий DRILLING _ LU Q m O' 5 MW5 I MWS...DB Type Drill(L/D>10, DC<3) OPERATIONAL GUIDANCE FLAT FACE Сверла Митсубиси по металлу Японский осевой режущий инструмент для сверления отверстий DRILLING _ Drilling a blind hole 1. Drilling a pilot hole 2. Initial cutting with the long type drill Use the SB type drill. Ensure a high precision hole is drilled for the guide. Drill depth Approx 1 DC. (Adjust the pilot hole depth according to the length of the long type drill.) Penetrate the guide hole at low revolution. (Revolution 1000min'1, feed rate 0.2 0.3mm/rev) Stop the long type drill 0.5 1.0mm short of the guide hole bottom. 3. Drill the deep hole 4. Drill retraction After drilling, lower the cutting revolution about 0.5 1.0mm short of the hole end. (Revolution of around 1000min‘1) Retract the drill to the pilot hole depth starting point at a feed rate of 3000mm/min. Finally, clear the hole at a cutting speed of 20 30m/min and feed rate of 0.2 0.3mm/rev. INTERRUPED Сверла Митсубиси по металлу Японский осевой режущий инструмент для сверления отверстий DRILLING _ Drilling and breaking through on irregular faces or angles 11. Spot facing 2. Drilling a pilot hole Machine a flat or the irregular face by using an end mill or slot drill capable of spot facing. Make the spot face diameter the same size as the required deep hole diameter. Use a drill with a larger (flatter) point angle than the long type. TheMWS-SB type is recommended. Ensure a high precision hole is drilled for the guide. Drill depth Approx 1DC. (Adjust the pilot hole depth according to the length of the long type drill.) 3. Initial cutting with the long type drill 4. Drill the deep hole Penetrate the guide hole at a low revolution. (Revolution 1000min'1, feed rate 0.2 0.3mm/rev) Stop the long type drill 0.5 1.0mm short of the guide hole bottom. 5. Breaking through Finally clear the hole at a revolution speed of 1000min'1 and feed rate of 0.2 0.3mm/rev. Retract the drill to the pilot hole depth starting point at a feed rate of 3000mm/min. 1692 Mitsubishi Materials
