Q:304 stainless steel material generally what kind of drill material processing?

Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel.

Q:Sharpening of drill angle when machining different materials

For the sharpening of the drill, we should grind the drill at different angles according to the needs of the drilling. For example, a bit of drill bit drilled to a relatively hard material can grind larger (i.e. flat);

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 to polish drill bit

Grinding twist drill is the front edge of grinding, we do mechanical processing, the new twist drill must be polished, and then used. A mill can also grind, but it must be worn by those who can grind it. Percussive drilling and percussion drills are necessary for drilling. Twist drills for metal.

Q:1 inches of steel plate, what drill can drill through?

1 cm steel plate? 5 cm steel plate, I have drilled, with ordinary drill, you own improper operation, steel plate to be fixed, must not move, do not force too much, the speed is not too high!

Q:What do you mean by 5 times diameter drill?

The length of the chip slot is 5 times the diameter of the drill bit.5 times a bit is the drill depth that can reach 5 times the diameter of the drill. For example, a drill with a diameter of 10 can process 50 deep holes.

Q:Drill hammer type matching specifications

Hard alloy electric hammer drill body made of high quality alloy steel, the knife head is welded with hard alloy. Matched with various electric machine, concrete, brick and other building materials for hard drilling. The utility model is a drilling tool with wide use and high efficiency in the construction and installation industry.

Q:M6 screws should drill big holes

1.M6 need to drill 4.8mm hole thread. Calculation method:2. generally speaking, the diameter of the Gong bolt multiplied by 0.86 is the diameter of the hole to be drilled.3.M6 thread refers to the nominal diameter of 6mm coarse tooth common thread.

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.

Q:My drill iron chuck is missing. How else can I take the drill bit off?

In any section along the bar, the flutes are located are diametrically opposed to each other's position in the flat tube, flat tube and two common edge edge in the pipe on both sides of the belt plane (F F) 90 degrees extension, wherein the knife rod has a maximum in the rigid plane. The orientation of the second plane (E E) of the center cutting edge is approximately 90 degrees with respect to the main rigid direction (F F) of the blade plane or the bottom of the cutter bar.
