- Q:Is there a standard for drilling errors due to machine tool shaking?
- Is the drill drill a positive or negative deviation, or is it bigger or smaller?. Bit wear is not serious, the drilled hole is a positive deviation. If the drill is used for a long time, the ligament is worn badly and the drill is worn out too, and the hole drilled is a negative deviation
- Q:Carbide drills and high speed steel drills, which are suitable for working stainless steel?
- The materials generally contain high melting point elements, large plasticity, high cutting temperature, so that the tool wear faster, sharpening and changing knives frequently, thus affecting the production efficiency and improving the tool cost.Mainly to reduce the cutting line speed, feed. With special processing stainless steel or high temperature alloy cutting tools, drilling, tapping the best internal cooling
- Q:Relationship between bit diameter and rotation speed
- If the bit is drilled at a low velocity, the drilling efficiency will be low due to the low line speed, and the drill bit will be easily broken due to the small size and the small strength of the drill bit. But because the bit in drilling, large diameter, high speed, line speed will be very high, the bit will be very easy to damage on sticky steel drill.
- Q:Why not hammer drill iron
- The characteristics of the electric hammer drill:1, a good shock absorber system: allows the operator to hold comfort, relieve fatigue.The way to realize is realized by vibration control system;Through the soft handle increased comfort grip;2 、 accurate speed control switch: when the touch switch is lower, it can help the machine to drill smoothly (for example, drilling on the smooth surface of tile, not only prevents the drill from slipping, but also prevents the hole from breaking. High speed can be used during normal work to ensure efficiency.3, stable and reliable safety clutch: also known as the torque limiting clutch, avoid large torque during use due to seizure caused by the reaction of bit transfer to the user, this is a kind of safety protection of users. This feature also prevents the gears and motors from stopping rotating.
- Q:Who can do this? Put the drill into it
- Change the hammer and steel ball to the service point. 3, time does not need, may not plug in, according to 1 of the method of force a few times just fine
- Q:1.5 of the stainless steel plate to drill 1.2 holes, the drill has broken a lot of roots, what kind of material with a bit better? How much speed, how much feed?
- Because 1.2MM this is a small size drill, so do not give a lot of feed, slowly feed, cooling liquid should also be in place. By definition, the thickness of the 1.5MM is very good, drilling, if it is a general stainless steel, then more than 1000 holes, a drill on the good. Of course, this means that the processed workpiece has not been processed.
- Q:Deep hole refers to the diameter of drill bits more than times, called deep hole
- Gun drill: only one cutting part, which was first used to process barrels. During drilling, the cutting fluid enters from the middle of the drill pipe and is injected into the cutting area through a small hole in the head of the drill bit and then removed from the V groove of the drill bit with the chip. The gun drill is suitable for deep holes with a bore diameter of 2~20 mm and a ratio of Kong Shen to aperture greater than 100. BTA deep hole drilling: the cutting fluid is fed from the gap between the drill pipe and the hole wall, and the cuttings are expelled from the inner hole of the drill pipe by the pressure of the cutting fluid. BTA deep hole drilling is suitable for drilling more than 6 mm hole diameter, hole depth and aperture ratio of less than 100 of the deep hole, and its production efficiency is more than 3 times higher than the gun drilling. The jet drilling: a multi edge deep hole drilling, inside and outside two layer drill pipe, most cutting fluid from inside and outside the drill pipe into the cutting area gap, and then together with the inner tube into the chip; the crescent hole and a small portion of the cutting fluid through the inner tube into the tail end of the inner tube jet formation, effect, low pressure area, help suction chip. The jet drilling does not require a strict cutting fluid seal. It is suitable for drilling deep holes with a diameter of more than 18 mm, Kong Shen and a bore ratio of less than 100.
- Q:How does an electric drill drill a hole in the 16mm with a 10mm drill bit?.
- The first shot 10mm hole, and then pull out the 1/4 distance in the clockwise direction of reaming, turn around, and then pull out the 1/4 left until the drill wall, then try to put what if the expansion screw is not wide enough to continue with the previous method, until enough, almost feeling hammered into the turnbuckle screw do not pay attention to the problems.
- Q:What's the difference between an impact drill and an ordinary electric drill?
- The percussive drill works by rotating and impacting and can be used for natural stones or concrete. Impact drill work in a drill chuck adjustment knob, adjustable normal electric drills and impact drills in two ways. But the impact of drilling is the use of internal gear to achieve mutual beat of impact, the impact force is far less than the hammer. It can also drill reinforced concrete, but it doesn't work. Hammer is a kind of electric drill, mainly used in the concrete slab. Brick and stone on the hole.
- Q:What is the material composition of the electric hammer drill?
- Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron, non-ferrous metals, plastics, chemical fiber, graphite, glass, stone and steel, can also be used for cutting steel, stainless steel, high manganese steel, tool steel and other hard processing materials.
