Q:How big bits are used for expansion bolts?
Know the expansion bolt diameter, can find out the tube diameter; the borehole diameter is slightly greater than the diameter of expansion pipe can be used, and expansion pipe of the same diameter aperture is slightly larger than the drill out tube diameter.
Q:How does the CNC lathe drill center to detail?
First use the center drill, the first smooth, the second pull, the Dutch, and the drill to the center of the workpiece drilling a small hole! The center drill is a CNC machining center tool used for drilling end faces, in the center, CNC drill hole clamping workpiece in NC lathe lathe, and then it will be used in drill hole slowly close to this method can be used to do, this method is much higher than the first kind of precision tool.
Q:What kind of drills are commonly used in CNC machining centers?
The drill is usually divided into high speed steel (HSS) and hard alloy (CARBIDE) according to our common material. If the machine spindle accuracy, large power, can use the alloy drill to improve processing efficiency, if considering the cost of the words of high-speed steel is cost-effective, of course, relatively low efficiency, in terms of an alloy drill to increase 1.5-3 times than the efficiency of high-speed steel drill. The advantages of alloy drilling: high hardness, wear resistance, high temperature resistance. Disadvantages: hard and brittle, improper use, prone to fracture.
Q:How big is the screw hole at the back of the torch chuck, Is it a rebound?
Usually around M5 or M6.
Q:How do you tell which materials are used in the test?
The commonly used twist drills are the hardness HRC62~68 of high speed steel (W18Cr4V or W9Cr4V2) after quenching.
Q:The difference between left and right drills used to drill holes
There are very few places to use left-hand drills:1, the modular machine tool porous drilling gearbox design, due to local restrictions can not change the direction of the wheel, only left-handed drill.2, when the attack left hand thread need to drill hole, plane moment is easily broken by alternating reverse gear, left-hand drill.3, drilling thin-walled parts will appear spiral line, can be left hand bit repair.4, some of the spindle is subject to restrictions, can not use the right-hand bit.
Q:Drill bit specifications
No, because the diamond drill bit and drill, impact drill bit ordinary regardless of specifications, size and shape are inconsistent, on the one hand can not install the clamping key is no guarantee of safety and accuracy.
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 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.
Q:Do you have any special drill for aluminum alloy?
Aluminum alloy, copper, stainless steel, these materials are not high hardness, aluminum alloy, copper soft, frequent drilling process, it is easy to have cutting, there will be a lot of burrs, aluminum alloy special drill.
