Q:The tip of the tip of the tip of the tip of the car in the outer circle of 90 degrees is higher than that of the material center

This is based on the actual situation: A. Machine clip - there are eight blade (four 90 - degree blade, four 75 - degree blade), multi degree of freedom cutting, especially used in car plane should point at the center of the high was on the material center (the same as the top), to prevent the transverse convex platform, its breaking point; (summary, as long as it is a flat face over machine tool center, what kind of car knife has to be at the center)

Q:When the outside circle is outside, is the car knife higher than the center of the workpiece changing the front Angle and the rear Angle

When a lathe is above the center of the workpiece the tool's main Angle and the rear Angle of the knife change little, but the rear Angle becomes smaller.

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

I put the knife in the pole and put it on the bottom of the pole. Don't burn the alloy. When the blade is red, the alloy is turning red. Where the copper is hot. Don't burn your ass, you'll have more experience...

Q:How to sharpen the cut of the lathe

Particle size The granularity indicates the degree of grinding grain size. The number of holes per inch is used to represent the number of holes in the ground. For example, the "60 granularity" means that the abrasive particle has a mesh of 60 holes in the length of each inch. Therefore, the larger the number, the finer the grinding grain. A rough grinding knife should be used to grind a small grinding wheel, and the grinding wheel should be chosen for a large number of grinding wheels. The ship's usual size is 46 - the medium or hard wheel of the platform 0.

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:What is the best Angle for a car knife

Under normal circumstances, when turning turning parts, if there are any blank contains a large number of hard material, easy to make the collapse of the cutting tools, in order to protect the blade, the blade and blade Angle, pour round processing. A little bit more, and less round. In addition, through the reverse Angle processing of the car knife, it can also get the actual front Angle bigger car knife, it is the turning performance of the car knife improved.

Q:Why is the tip of the blade of a hard alloy lathe smaller than a high speed steel tool

I think the reason for the small arc is 1. Add location 2. Fast cut 3. Reduce the head friction and improve life 4. The rows are turned on the axial force, smoother

Q:Which direction does the transverse orientation of the lathe point in?

Is perpendicular to the axis of the processing axis.I hope my answer will help you.

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

Q:To design the tool manual for the shape of the rib body

Working part of the lathe tool is a portion of production and the processing chip, including the blade, the structure of the chip broken broken or volume approach, chip removal, or should the storage space of the chip, cutting fluid channels such as structural elements. The cutting part of the tool is made up of the main cutting edge, the side cutting edge, the front edge of the knife, the face of the blade and the face of the blade. The combination of the cutting part and the handle part (the filling part) is mainly the integral, welding, mechanical clamping and weld-mechanical clamping. The mechanical clamping tool can prevent hard metal blades from cracking during high temperature welding, and the handle can be used several times. The mechanical clamping tool is used to clamp the blade tightly with screws and press plates, and the mechanical clamping tool with indexable blade. The edge of the blade can be used after being blunt, and it can be stopped for a blade
