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:What's the angle of a standard twist drill?: How much is the standard twist drill angle - 118 degrees, drawing (the threaded hole is a blind hole at 120 degrees) according to the draw.

Q:How do you tell which materials are used in the test?: The drill shall be selected according to the material properties of the material to be machined. For example, stainless steel uses cobalt cobalt drills. Use tungsten cobalt alloy bit when producing high heat when the bit is cutting

Q:What drill is used for machining holes with a diameter of 3mm?: For the steel parts which require fine matching, it is recommended to drill holes with a twist hole smaller than 3mm and then drill with a 3mm bit to ensure the accuracy of the hole. As for plastic, cardboard or copper material, the aperture will be retracted. The drill bits which are slightly larger than the diameter of 0.10mm are generally used. If the machining requirements are strict, it is better to drill rough first. For example: first drill with 2.5mm bit, and then use 3mm bit reaming, so that you can guarantee the accuracy of aperture.

Q:What drill heads are used to drill holes in diamond heads?: General screw drill or tungsten steel, tungsten steel twist drill.

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:How does an electric drill drill a hole in the 16mm with a 10mm drill bit?.: 1. Use a ruler to measure the length of the 16MM around the wall. Mark the mark with a pen.2. Drill the drill with 10MM, drill a 10MM hole in the middle of the mark.3, with 10MM hole as the center, continue to open the drill, slowly rotating in a clockwise manner.4, rotating to the mark position, 16MM hole will be completed successfully.Remember, you can't go too far. You should take it slowly. You can turn it clockwise and counter clockwise for a while.

Q:Drills, drills, heating drills, will they be annealed?: So in need of cutting fluid filling drilling, cutting fluid can take away a lot of heat cutting when cutting, cutting temperature, and the cutting fluid can penetrate into the workpiece, cutting tool, the lubricating film formed between the chip and the tool and the workpiece, can reduce the friction between the chip, thereby reducing the cutting deformation of bue growth inhibition. And the cutting fluid can be a small chip away to avoid clogging timely or scratch the workpiece machined surface, reduce the surface roughness value, reduce the thermal deformation of workpiece and ensure the machining accuracy and improve production efficiency.

Q:What steel blade drill bit, hardness above 60: It is recommended to use steel bit, two hundred to three hundred RPM (8mm below the hole, more than 8mm, and then reduce speed), pay attention to cooling, the amount of feed should not be too large. For reference only, I hope it will help you.

Q:How much bit should we use to punch the M5 hole? Tapping with Duodasi attack? Why use 8.3 drill bit in the hole of M10? How do you know how big it is to punch and tap?: If the material soft bottom be slightly smaller, so hard to be slightly larger. As the aluminum tapping hole to drill small, alloy steel tapping will be slightly larger. M5 has a pitch of 0.8, so use 5-0.8=4.2's drill. The pitch is 1.5 M10, normal use 8.5 bit, if 8.3 words may be used as the material of soft, normal bit will lead to larger hole.
