Be sure the power socket is off and the switch of electric motor is off before the installation. Install the drilling machine by the corresponding installation diagram.As it shows in the picture:Insert proper PILOT PIN into the center hole of the product※ WELDON SHANK As it shows in the picture: aim the two planes of the SHANK to the 两喉噻顶丝孔 of the principle axis of the drilling machine. Tightening it with hexagon wrench and leaving 0.2-.03mm gap, turning it reciprocating with hand to confirm its place, and then tighten the 顶丝。 ※ 通用柄 As it shows in the picture: aim the small dot of the SHANK at the index line of the principle axis, and then push up. When hear the click sound, it’s ok. ※ FEIN QUICK-IN As it shows in the picture：turning the 保险环 which is on the principle axis clockwise fully, and insert the SHANK in then turning slightly till hear the click sound. 2. Spotting. Make an anchor spot with centre chisel (中心錾) or draw a cross with the alloy needle on the place where the hole will be bored in order to guarantee the precision of the drilling position. Caution: when make anchor spot with centre chisel, make sure it’s perpendicular to the surface of the 加工工件 so that it won’t affect the discharge of the cutting scraps (料芯) 3. Wh en the drilling begins, adjust a proper rotate speed. Before turning on the magnetic drill, first make sure the cleanness of the bottom of the machine. First turn the switch of the magnetic support electric motor, turn on the switch of the cooling off fluid when the electric motor is working. Then slowly input …until the cutting becomes stead, then speed up the input speed properly by force, but please don’t push to hard.4. After the drilling, turn off the switch of electric motor. When the principle axis stop spinning, please remove the iron scraps that are wounded on the machine by iron hook, and then can it continue working. 5. When drilling, please pay attention to the following situations: (1) When the machine can’t discharge waste smoothly or the iron scraps become powder, one should check whether there are so many iron scraps wound on the machine that affected the discharge of those iron scraps. If yes, one should get rid of them. If no, one should then check whether the cutter is worn, if yes, one should replace it with a new one. (2) If the principle axis stops spinning, please first turn off the electric motor in order to protect the cutter, then turning the axis to the opposite side for 1mm, then lift up the electric motor. (3) When the round scrap can’t be discharged, please use non-metal stick hit the machine other then the cutter part slightly until the scrap comes out. (4) When work on poly-tire planes, please discharge the round scraps and wounded scraps for each tire and then go on work. (5) When work on hard material, please make sure the machine is cooling down thoroughly, for there will be too much heat, so as to prolong the life of the machine.

1. Main difference of end mills made of good tungsten carbide and common tungsten carbide (different material and the same manufacturing process)They have similar performance on hardness, toughness and the difference is on the wear resistance, which mostly decides the life of the end mill.End mills made of common tungsten carbide only apply for cast iron, carbon steel, low alloy steel, copper alloy. These materials have low tensile strength (under 1000Mpa) and low hardness (under 30HRC). For stainless steel, high alloy steel, prehardended steel, hardened steel (high hardness or high tensile strength), these end mills have inferior performance and even can't work on these materials. Usually the life of end mills made of tungsten carbide is about 30% shorter than that of end mills made of good tungsten carbide when milling low tensile strengh materials or low harden materials.2. Main difference of end mills made of CNC machine and common machine (the same tungsten carbide)They have the same performance on hardness, toughness and wear resistance and the difference is on the tolerance.Usually we have 3 types of tolerances on end mills, tolerance of shank and diameter, tolerance of flute and tolerance of cutting edge. They have the same tolerance of shank and cutting diameter. The main difference is on the tolerance of flute and the tolerance of cutting edge. For milling metals, the most importance is to make sure that the cutting edges of end mill can touch the work-piece at the same time, which need smaller tolerance of end mill. And, we can control the tolerance of cutting edge in 1S (0.01mm) by CNC machine. The common machine can control the tolerance of cutting edge in about 5S (0.05mm) if the workers are on good status. So, when milling metals, the end mills made by common machine shall have one edge or 2 edges touch the surface firstly and others touch the surface lately. As for end mills made by CNC, the four edges touch the surface at the same time, which can improve the life of end mill greatly. Usually the life of end mill made by CNC machine is 40% longer than that of end mill made by common machine. Anymore, the end mill made by common machine only apply for low speed cutting (under 30m/min).3. Usually, we use 3 brands of tungsten carbide to make solid carbide tools. They are K10, K20, K30 and sometimes, we also use other brands of tungsten carbide for special usage.
