- Q:Electric hammer drill killed what should take down
- 1, backward extrusion head, drill can be pulled out.2, black down, iron also press down, it came out.3, there may be a problem that the pearl inside the chuck. The drill down, pressure head black chuck, a few more to return a bit range.
- Q:The threaded hole M5 general drill big bottom
- M5 is an ordinary coarse thread, with a pitch of 0.8mm and a nominal diameter of 5mm. General coarse thread without marked pitch.
- Q:How about the speed of the drill bit and the feed of the cutter in the machining center?
- 1, if I first drill with D13 bit (S600, F80, Q5), and the rest of all milling cutter hole2, casting and steel parts almost turn, the speed can be faster. After 28 of the hole points, use 28 bit S300, F50, Q3. directly3, 35r6 direct spiral down, layer below 0.5-0.8, S1500, F2000-3000
- Q:What's the difference between full mill and rolling twist drill?
- The full grinding twist drill is made of Kunlun twist drill, which is especially high cost, especially durable, and can be used by 1 of them for more than 300 eyes! It is awesome, and playing is stainless steel.
- Q:What are the weight specifications of the drill pile when the bridge pile foundation is constructed?
- In terms of size, this depends on the size of the hole you want to play. Generally they are 0.8m, 1M, 1.25m, 1.5m, 1.8m.
- Q:What are the brands of homemade twist drills?
- General twist drill rolling and grinding, high quality grinding, I used, there are good brands in the processing of steel parts on the whole: drill, drill Gongquan full amount, mine drill, drill the Far East
- Q:What bit is better for drilling 304 stainless steel?
- Recommend two bit, a cobalt high speed steel drill, a kind of high performance cemented carbide drill bit, cobalt high speed steel prices, but the short life, low efficiency, poor accuracy, need to pre order centering drill better; hard alloy drill special stainless steel price expensive, but also life a lot of high efficiency, high precision of hole size, also, finish too high a lot, without centering drilling machining, can be directly used cobalt alloy drill drilling; compare the two contrast, characteristics of stainless steel is high toughness, easy to stick a knife. So the drill head hardness is high, the main component is hard alloy tungsten carbide, cobalt, hardness is generally high in HRC90 degrees, cutting fluid with emulsion concentration. The cutting speed is as low as possible, because the 304 stainless steel easy drilling so as to reduce the temperature for heating chip.
- Q:How big is the 6 bit that the worker says?
- The default length units for machining and mechanical drawing are millimeters,
- Q:Deep hole refers to the diameter of drill bits more than times, called deep hole
- In machining, the hole with a hole ratio greater than 6 is usually called a deep hole. In deep hole drilling, it is difficult to get rid of heat and chip, and it is easy to bend and vibrate because of the poor rigidity of the drill rod. Cooling and cooling systems are usually used to solve cooling and chip removal problems. The classification of deep hole drilling is divided into two types according to chip arrangement: chip and chip. There are 3 kinds of chip removal drill, deep hole flat drill and deep hole twist drill. The internal chip removal is divided into BTA deep hole drilling, jet drilling and DF deep hole drilling.
- Q:How does the CNC lathe drill center to detail?
- If the drill, on center is not very high, generally to come to the center point can drill bottom.If it is a center drill or hard alloy drill, the requirement is higher. At this point, the center height of the machine tool holder must be right, the center height is not right, and you are not to the center position
