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: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:How do you grind the diamond tool?
Before grinding, diamond powder is first mixed with olive oil or other similar material into a paste, then coated on the surface grinding disc, placed a period of time to paste into fully cast iron pore grinding disc, with a large diamond in grinding disc surface of pre grinding back and forth, to further strengthen the role of Mosaic diamond powder in cast iron pore. In the case of grinding, the grinding diamonds are usually buried in a tin bucket, showing only the grinding surface.
Q:Can CNC lathe tool be replaced by welding knife
Welding tool: just as its name implies welding tool is a way for the blade and blade part of the connection, through the dehydration of borax, copper, ferromanganese, glass beads and other solder, by high temperature melting, let alloy, high speed steel,, diamond and cubic boron nitride ceramic material such as razor blades and trough consistent tool rod sticking together, in order to achieve the demand of machining operations, a turning the most widely used for hard alloy welding tool, because of the hard alloy hardness is higher, can reach the use requirement, most of the processed material and relative to other material cost is very low, accordingly so widely used, carbide welding tool according to the properties and processing object is mainly divided into three kinds, red handle for YG class, represented by YG6 and YG8, mainly used for cast iron, non-ferrous metals and non-metallic materials roughing, skinned homework, advantage is high bending strength, the disadvantage is that poor abrasion resistance, can only be used for low speed processing, yellow handle for YW classes, with YW1, YW2 represented, it is mainly used for high viscosity material such as stainless steel semi finished and finish machining, YW class alloy high hardness, wear resistance, but the bending strength is limited, is suitable for high speed small feed processing, is versatility better carbide, blue handle to YT classes, represented by YT15 and YT5, suitable for 45 # steel, plain carbon steel processing, high hardness, bending strength is poorer, wearability is good, mainly for roughing and semi-finishing.
Q:Lathe problem: the round groove of lathe knife how to grind?
A little personal experience: It is very important to sharpen the cutting edge of the blade, and the style is different. But the general rule is pretty much the same. The shape of the groove should be determined according to the depth and quantity of the cutting, and the radius of the channel is slightly less than the radius of the roll, and the width is generally less than the cutting depth. Note: the tip of the knife is higher than the blade (the tip of the blade). If the blade is lower than the blade, the blade should be deeper, or the slot is higher than the blade, and the cutting will be directed to the left.
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:90 degrees can't make a car face! What's the difference between a 45-degree car knife?
The 90-degree turning point is positive and anti-vehicle, and the vehicle is in the outer circle, and the anti-car knife is in the plane. The 45 degree vehicle can be used to both the outside circle and the car plane, but the 45-degree vehicle can't be straight with the platform shoulder. The 90 degree car knife has a 45 degree blade, which has a different blade Angle and a different direction. A 90-degree left side knife is usually used for the ends.
Q:Does the grinder work with the grinder or the universal grinder?
First of all, it is best to use a grinding wheel grinder for a sharpener, and it is better to grind a knife. As to the car technology is the knife, the precision, the degree of proficiency is usually these, the most basic.
Q:The difference between the threading tool and the external turning tool
When the rib is in the rib, it is a fan. The sharp corners of the knife should be the same as the thread's rib Angle, usually 60 degrees. The external turning tool is not required.
Q:I use acetylene oxygen to weld a common lathe blade. Why does the blade keep cracking
Ultra-fine grain cemented carbide is to improve the hardness and bending strength and at the same time the development of the alloy material, compared with common hard alloy materials, has a higher strength, hardness, being the same in the intensity of phase has the characteristics of higher hardness at the same time. Ordinary carbide WC particles is about 1 ~ 6 microns, the ultra-fine grain cemented carbide WC particles is only 0.6 mu m, because the WC particles are very small, so the thickness of adhesive around the function of Co components is thinner, at the same time, because of the broken starting small size, high bending strength.
