Q:What is different about the shape of the external turning tool and the inner circle tool?

Of course, the external turning tool is not the same as the inside. I have this "mechanical manufacturing process basic textbook" friend if need, add my QQ: 769940117: machine manufacturing process basic textbook

Q:How much air hammer do you use for forging a lathe? How to weld a car knife?

Brazing technology. You can go and look at it, the smaller one is 15KW, the big one is 25KW or more

Q:What are the types of car knives?

The tool can be divided into outer circle, shoulder, end face, cutting, cutting, thread and forming tool. There are also car knives for automatic line and digital control machine tools. The structure can be divided into the overall car knife, the welding tool, the lathe tool, the turning tool and the shaping tool

Q:There are several kinds of lathe knives for regular lathes

The type and purpose of the tool The blade is the most widely used single blade cutter. It is also the basis for learning and analyzing various kinds of knives. The lathe is used for various kinds of lathe, processing outer circle, inner hole, end face, thread, car slot and so on. The structure of the tool can be divided into the overall car knife, the welding tool, the lathe tool, the turning tool and the shaping tool. The use of indexable turning tool is becoming more and more extensive, and the proportion of the blade is gradually increasing.

Q:How to weld a tool

The structure of welded cutting tool should be sufficiently rigid Sufficient rigidity is guaranteed by the size of the maximum allowable dimensions and the use of high strength steel and heat treatment.

Q:Hello, I ask you a question, how much of an Angle will you wear with a white steel knife?

Speed is too high to copper don't hit such a high speed car ~ can't add cutting fluid to high speed machining copper knife grinding hard ~ hot knife fast easy to wear, you wear white steel knife to sharpen some additionally, feed is generally based on material and rotating speed, but have a roughly the speed, the iron material generally around 100-800, around 700-800 in copper and aluminum has the highest speed, 2000 turn can, cast iron in 100-300 turn around, the adjustment of the feeding speed is the speed and feed rate ~ are generally from experience, I do the lathe work more than 4 years, how much I haven't seen feeding speed, only know a living and feed quantity and speed. Copper can be a little bit bigger, but the knife is worn as short as possible, if I give you a knife in your 20 minutes

Q:How does a lathe tool grind not to have a burr on the piece?

Knife grinding according to the material, material hardness, allowance for reasonable grinding tool face Angle, different size coarse car finishing tool, slot depth and the width is then strain, to years of experience is not to say that the can be on the basic skills are solid.

Q:The process of the welding of the lathe, the more detailed the better.

Can use the welding tool holder first heat to 500-600 degrees Celsius, and then put the cutting head, reoccupy after burn red copper electrode with a moderate amount of borax flashing in the tool holder and the junction of the cutting tools, pay attention to the cutting head not to overheat, copper electrode borax to uniform.

Q:What do you have to do when you have a full-body tool and a welding tool

Regular blade grinding die not only increases the life of the die, but also improves the service life of the machine, so it is very important to master the correct and reasonable time. Mould need grinding for users is direct approach is: after punching accumulated to a certain number of times, to check whether there is larger burr punching quality produce, check whether the die cutting edge rounded corners on (rounded corners p RO. 1), whether gloss disappear, if you have this kind of circumstance happening, illustrate the punch is dull, at this point needs sharpening. Die if grinding at the appropriate time, 3 times can prolong service life, but not the correct grinding, instead will increase sharply mold edge damage, reduce its service life, mold has its form a complete set of mold grinding machine, grinding, choose the appropriate grinding machine will be greatly convenient for the user, improve production efficiency.

Q:How do you break the blade

In the case of grinding the blade of the knife, the main two functions are to make the cutting and the cutting briskly.
