Q:High speed steel tool for high-speed cutting

No, it can only be used for shaping tool, low speed turning, and sufficient cutting fluid.However, high speed steel is suitable for high-speed cutting.

Q:What kind of tool can you use

?cr18ni9ti with silvery white breadcrumbs end milling cutter, the geometric parameters for gf = 5 °, gp = 15 °, 15 °, af = = ap 55 °, 5 °, kr = k 'r = 35 °, 30 °, bg g01 = - = 0.4 mm, re = 6 mm, when Vc = 50 ~ 90 m/min, Vf = 630 ~ 750 mm/min, and a' p = 2 ~ 6 mm per tooth feeding up to 0.4 ~ 0.4 mm, milling force decreases 10% ~ 15%, and the milling power down 44%, also greatly improve the efficiency. Its principle is on the main cutting edge grinding out negative chamfer, milling artificially generated when the devolop tumor, instead of cutting edges for cutting, the devolop tumor of the anterior horn of gb of 20 ~ 302, as a result of the action of the main Angle, the devolop tumor caused by a knife before surface parallel to the thrust of the cutting edge of the chip to become vice flow, to take away the cutting heat, reduces the cutting temperature.

Q:How to weld a car knife? How do you handle the welding fire

If you don't weld it, you don't understand it. Heat the blade to the red (solder tip) to apply borax, the blade (alloy), and the blade to continue to heat (while heating the copper electrode, apply borax). The temperature is high, the copper electrode is burning and the welding quality is affected.

Q:A numerical control car tool, what materials are used in the car

The other kind of without cutting slot, the market is not too much, the order is usually required, the tip of the blade is slightly tilted, and more than 0.8. Car non-ferrous metal, copper, aluminum, easy cutting steel, diamond knife, smooth finish to 0.4 car quench workpiece, with the cubic nitride taut tool head. Stainless steel and cast iron also have their own head, not too much, don't remember the number! These are really good choices. You just buy a knife and make it clear to the cutter that they will choose the tool for you. But don't buy domestic knives. You don't usually specify a tool brand. They will give you the head of zhuzhou and the English tools of chongqing. Because the knife is profitable! Also, the tool must use R0.4 and R0.2. The cutter will sell you 0.6. Because they can't sell it!

Q:What is the reason for the grinding noise of a lathe tool on a regular lathe

The Angle of the car knife is not right, the grinding knife, or the turning tool holder.Insufficient system rigidity; The knife Angle is not reasonable..

Q:Does the tip of a regular lathe break down the blade of a tool

It should be small, maybe it's a gap and it's a big relationship.It's a bit of a relationship, and nobody knows the extent of the impact.

Q:What kinds of car knives are used?

Type of car knife: the overall turning tool of the car knife can turn a turning tool and the shaping tool. (turning) is on the carbon steel tool rod out according to the requirement of the cutting tool geometry Angle groove, the carbide blade welding with welding powder used in the groove cutting tool. Using the mechanical clamping method, the blade holds the blade in the blade. (indexable lathe tool) is a machine tool with indexable blade, most of which is used in nc machine tool. Translocation blade - is a blade with multiple blades of the same cutting edge. And at least three or more (triangulation, square, quadrilateral, etc.) Turning tool - a mechanical clamp with three different structures...

Q:Lathe tool welding method!! Concrete action steps!! Precautions should be taken!

The children of the wrong people upstairs, not even borax? Still teaching people to burn knives? Actually very simple 1: the alloy tool head and the blade are smaller and can be placed directly in the Angle (the cut Angle you want) 2: from beneath the sword of the cutting tools by gas welding rod heating (heating alloy material loss of the cutting tools for a long time, reduce the tool life), make the cutter bar and reach the orange of the cutting tools, and borax from above by welding melting copper electrode, copper water gap filling with respect to ok. Notice: 1: the tool holder and tool bit interface level off is smooth with no greasy dirt and rusty spot, the temperature must be orange, uneven copper water temperature is too low, welding, tool rod is too large to heat. 2: the welding tool should be cooled slowly in the natural temperature, not water or other liquid to cool rapidly, preventing the crack of the tool.

Q:How do you understand the height of the tip center

The large diameter of the workpiece can be done without doing anything. Small words will have to be in the middle. The knife is less sharp when it is low. Dull,

Q:How is the welding tool produced?

Is turning on ordinary carbon steel tool rod welding, brazing carbide blade, after grinding (figure 4-19), and its advantages are simple structure, easy fabrication, and can according to the need for sharpening, the use of cemented carbide is sufficient, so quite proportion at present is still in the tool. Defect is the cutting performance of carbide turning tool mainly depends on the workers of the grinding technology, with modern production does not adapt, moreover tool rod can't reuse. In the manufacturing process, as a result of hard alloy and tool rod material (usually medium carbon steel) of different linear expansion coefficient, when the welding process is not reasonable easy to generate thermal stress, seriously will lead to crack of cemented carbide, when welding carbide insert accordingly, should as far as possible using low melting temperature of solder, the blade should be slow heating and slow cooling, for easy to produce crack YT30 are cemented carbide, should put a layer of stress compensator in weld. The welding assembly tool is a carbide tip that is soldered to the blade, and the blade is mounted on the tool pole. This structure is used for heavy vehicle knives. Heavy tool size and weight is bigger, use after welding fabricated structure, only need to loading and unloading of the knife block, grinding energy, tool holder can be repeated use
