- Q: What is the standard angle of the drill bit?
- For example, HSS high-speed steel drill bit: vertex angle is generally 118 degrees, sometimes greater than 130 degrees; sharp blade; accuracy (blade height difference, symmetry, jitter) requirements are relatively low. There are many ways to correct the transverse blade. Hole roughing and less demanding, we generally use more. HM carbide drills: the top angle is generally 140 degrees; straight fluted drills are usually 130 degrees; and three edge drills are usually 150 degrees. The blade and nose (edge) are not sharp, often passivated, or inverted blade and chamfering, and require high accuracy. The horizontal edge is often into a S- shape, in favor of chip breaking
- Q: What kind of drill bits are used in glass drilling?
- Drill glass has special drill bits, steel sand drills.Use a twist drill to drill glass. The glass is easily broken and cracked. If you must use a twist shape, buy a milling cutter. It is not easy to use a milling cutter to drill holes in glass.If you buy high-speed steel twist drill is really qualified high-speed steel material, you can drill through the glass, if high-speed steel is not possible, you may consider carbide steel.Small steel sand drill bit will be about 3 yuan, cheaper, it is better to buy this thing.Of course, the diamond is also OK, just so expensive.
- Q: Can an electric drill bit a wall?
- Percussion drill: general impact drills are dual purpose. First, the function of the ordinary electric drill, two is adjusted to hammer, punching function, put on alloy drill, you can drill in the wall, but drilling ability is poor;
- Q: What drills should be used to drill holes with diameter 5mm and depth 65mm? Urgent! Thank you!
- An ordinary twist drill with a diameter of 5mm and an effective working length of 80mm. High turn, frequently anti chip, multi pour cooling liquid.Only 65mm deep hole ah, just find a 5 drill bit, as long as long enough, the key is to see how the drill grinding.Parabola drills are generally long long hole drill 65 waste and can really wear parabola drills and few people.
- Q: How to allocate the electric hammer drill
- 1, backward extrusion head, drill can be pulled out.2, black down, iron also press down, it came out.
- 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 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: The whole alloy drill often breaks
- 1, choose machinery with better mechanical performance to minimize the unevenness of bit feed.2, fixed firmly machined workpiece, minimize and avoid workpiece vibration, workpiece beating phenomenon.3, the processing of the feed should be stable, slow, slow, remember to act too hastily.4, if all aspects of the existence of factors, can not guarantee smooth drilling, you may wish to use carbide inserts bit. The body of this drill is made of tool steel, except that the cutting parts are inlaid with carbide inserts. The drill bit does not hurt even if there is a certain amount of vibration when drilling. It will not cause the bit to break.
- Q: Good or good tungsten cobalt steel drill bit.
- Cobalt drill good impact resistance. For the machined material hardness, or vibration machining occasions.
- Q: What causes the drill bit to break at the end of the hole?
- The cutting edge angle is not proper, and the iron chip blockage causes the resistance to increase.1) and the principle of uniform, when the edge angle is not appropriate, the drill operation must not only overcome the cutting resistance, but also overcome iron friction and pore wall blocking resistance, resistance and greater than two fold twist drill strength, also can cause the drill bit break.
