Q:How to use glass drills?
With the drill bit in the hole on the glass, water glass drill bit 80 degree angle at the hole grooves and then gradually transferred to a glass surface 90 degrees vertical to continue drilling, and continue to add water cooling the drill bit when drilling, 5mm stopped the machine out the bit within the glass pieces and then drilling. Clean up until the desired depth is reached.
Q:What kind of steel do you need to drill?!
A cemented carbide drill bit with an average size of 1 microns. This kind of drill not only has high hardness, but also improves the compressive and bending strength. In order to save the cost of many bits by welding handle structure, the original bit for the whole hard alloy drill, the back part of the handle adopts stainless steel, but the cost is greatly reduced due to the use of different materials and its dynamic concentricity is inferior to the whole hard alloy bit, especially in the aspect of small diameter.
Q:How big is the screw hole at the back of the torch chuck, Is it a rebound?
If the chuck is to be assembled, stop the spindle from turning, and some have a rectangular edge that clamps the parallel edge with a thin, corresponding opening.
Q:8mm iron expansion bolts with few drilling drill mm?
It's a gross mistake to say 8 mm punching. As with a hammer smashed bolt can not. Strictly speaking, 12 mm bit should be used, but if the expansion bolt is not standard, you need to drill 10 millimeters, then twist the hole, it is best to use caliper to measure the diameter of the bolt and then decide
Q:What does the cutting depth of the drill mean 3D?
That is, the diameter ratio of the drill, such as 3D, and the diameter of the drill is 20MM, the effective drilling depth is 60MM
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:What is the drill bit of the percussion drill, please?!
Percussive drills work by rotating and impacting. Percussive drills work by rotating and impacting. A single shock is very slight, but a shock frequency of more than 40000 minutes per minute can produce continuous force.
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 big is the drill bit for the 7mm hole?
If 7 holes are machined, 6.9 bit holes are used, and 7 reaming holes are used to obtain the qualified holes
Q:What does SDS+ mean in a drill?
Also useful plus or max, SDS+ (SDS plus) said the four hole round handle drill, SDS Max said the five hole round shank drill, you think, the drill bit is fixed with 3 tunnel, a tunnel called plus, 5 very close, almost no room, so it is indicated by Max.
