Q:The choice of the threading tool and the residual choice of the turning process
Metric common thread with 60 ° Angle of knife mold, national standard trapezoidal thread with 30 ° Angle of knife mold. Residual quantity of thread: after the thread of the car, the grinding thread should be left with 0.6 to 0.8 mm in the diameter of the diameter. Keep 0.3 to 0.5 mm spare from coarse thread to fine car. The total depth of the vehicle thread is 0.65 P.
Q:What is the difference between a CNC lathe and a fine turning tool?
The main difference is the grooves of the tool and the tip of the blade, and the other is a small difference in the material.
Q:What kind of alloy is the car knife used?
Cobalt tungsten tantalum (WC + TaC + Co) carbide (YA) on the basis of class YG carbide added TaC (NbC), improve the normal temperature, high temperature hardness and strength, thermal shock and abrasion resistance, can be used in the processing of cast iron and stainless steel.
Q:Why do you put a knife in a knife
Because of the requirement of pouring steel, the cost is high. The general small factory can't do, water the use of steel to use the habit, did not switch to forge
Q:The type of circular lathe tool of CNC lathe
There are high speed steel, hard alloy steel and so on.I hope my answer will help you.
Q:90 degrees will be able to cut out the outer ends
The ability to cut depends on two things: The blade has the cutting edge of the blade when the radial tool is removed. Most of the blade can use radial blade. If it is a blade on the right and left hand, it cannot be used in the radial direction. 2) there is a side Angle when radial walking knife (car face). 93 ° or 95 ° a knife, there are 3 ° and 5 ° Angle. If it is 90 °, surfacing, crowded.
Q:How do you break the blade
The second is to make the chip curl, the smaller the radius of the chip, the easier it is to break. The ability to crack is also related to the performance of the cutting materials.
Q:Is the CBN turning water cut
Nitride boron PCBN cutter: (used for fine processing) Professional finishing CBN superhard cutting tools, the main cutting of hardened steel, alloy steel, tool steel, die steel, manganese steel, spring steel, bearing, chilled cast iron, high chromium cast iron and grey cast iron, powder metallurgy, Ni and CO base superalloy rockwell hardness in (HRC45-80 °) between the various kinds of difficult processing and high hardness steel. Feature 1: smooth and clean surface of the surface of the surface of the smooth finish. Characteristics 2: super hard wear-resisting, high resistance to tool hardness; Feature 3: cutting speed is high - high speed cutting speed can effectively reduce the cost of processing efficiency.
Q:The Angle of the blade of a CNC lathe is R
Normal use is 0.4, 0.8, finishing the requirements of high speed, the machining allowance is relatively smaller, small artifacts when sometimes use 0.2 rounded corners, to reduce the deformation of the workpiece
Q:Grind hard alloy lathe tool, want to soak water to cool, in case the blade annealed, right?
Everything has to be said, the hard alloy car knife is only cool, but the temperature is slightly higher and it can be scrapped, which is generally not allowed to cool down.
