Specifications of cutting tool

Including external turning tool holders, boring bars, threading holders, grooving holders, cartridge and micro turning tools.

As the first product, our turning cutting tools has the following impassable advantages:

· our turning cutting tools cover a wide application range with a full line-up of ISO cutting tools that produce high quality and high precision cutting tools and parts for all manufacturers’ requirements.

· Main cutting tool’s type include external turning tool holders, boring bars, threading holders, grooving holders, cartridge and micro turning tools.

· All the spare cutting tools are made by ourselves, stable and controllable quality can reduce the wear of the insert and adjustment time.

Application

· Mainly use for turning machine, boring, grooving and threading in NC Lathe.

cutting tool

Q:Method of shock absorption of inner hole tool: The main reason is 1. Blade sharpening 2. Cutting quantity 3. Spindle speed 4. Steel 5, parts material 6, the shape of parts Here to tell you a solution to thin wall parts car hole method to avoid shock knife, and find some things of bicycle tube tightly set outside the artifacts, the effect is very good oh, can draw lessons from it

Q:What are the advantages and disadvantages of welding and machine tools?: For welding, it is best to control the temperature of the welding, reduce the stress, and the flux is also important.

Q:Why is the front Angle of the threading tool zero?: Many of the tools that have precise shape requirements (threading knives, rolling teeth, slotting knives, etc.) are generally zero. The shape and size of the blade are "closely related" to the shape of the shape, which is also easy to measure. Angle of processing before, of course, there are more "portable", tool life is higher, but, measurement of trouble, a former Angle of blade surface, shape, size have change, although very small

Q:What are the special requirements for a blind car knife?: Simply put. The Angle of the blade is less than 90 degrees, about 80 degrees. (actually the look line, as long as live not collision hole bottom line, as to how many degrees would amount) this point is more stress, don't car too thick.

Q:The problem of car knife brazing: Requirement for welding welding flux It is suggested that the industrial borax should be treated by dehydration in the drying oven before using, and then it will be crushed, and the machine will be removed and removed. Welding titanium low cobalt fine alloy and high alloy welding the long, thin blade, in order to reduce welding stress, and suggest the thickness of 0.2-0.2 mm wafer or mesh aperture 2 -- 3 mm spacer mesh compensation on welding. Due to large carbide insert brittleness, the crack formation sensitivity is strong, so the cutting tool in the process of grinding should avoid overheating or quenching, as well as choosing appropriate particle size of grinding wheel and reasonable grinding process, to avoid grinding cracks, affect the service life of the cutting tool. When the tool is installed, the length of the tool holder should be as small as possible, otherwise it can cause the tool to vibrate and damage the alloy plate Cutting tool used to achieve normal grinding blunt, heavy grinding, must be conducted after resharpening of knives, must use oil stone to grinding blade and blade edge, which will improve the service life of cutter and the safety and reliability

Q:I use acetylene oxygen to weld a common lathe blade. Why does the blade keep cracking: Welded structure of cutting tool should have enough rigidity, enough rigidity is the appearance of the maximum allowable size, and USES high strength steel grade and to ensure that the heat treatment. Carbide blade should be fixed firm, for example, cemented carbide welding blade should have enough degree of fixation, it is to rely on groove and welding quality to ensure that, generally speaking, according to the shape of blade and the cutting tool geometry parameter choice blade groove shape. It is necessary to inspect the blade before the carbide blade is welded to the blade, and the blade must be inspected first. Hard alloy welding surface must not have serious carburizing layer, at the same time should also will carbide blade surface and cutter bar set of dirt to clean, to guarantee the welding. In order to ensure the welding strength, choose the suitable solder. During the welding process, good moisture and liquidity should be guaranteed, and the bubbles shall be eliminated, and the welding and alloy welding surfaces shall be fully in contact with the welding phenomenon. Welding flux choice: borax industry, can be used in the drying furnace shall be carried out before use dehydration processing, then crushed, sieve to remove mechanical impurities in again. Use mesh compensation pads. For example: in the welding of titanium high low cobalt fine alloy and welding of long and thin blade, in order to reduce welding stress, and sheet thickness of 0.2 ~ 0.2 mm can be used or mesh aperture 2 ~ 3 mm spacer mesh compensation on welding.

Q:How to weld a tool: Requirement of welding welding material In order to guarantee the welding strength, should choose the right solder. In the process of welding, shall ensure that the good wettability and liquidity, and to eliminate air bubbles, make a good contact with welding and alloy welding surface, shape welding phenomenon.

Q:The difference between the threading tool and the external turning tool: From left: 90 ° cylindrical turning tool, inner hole threading tool, inner hole tool, blind hole cutting tool, cutting knife, threading tool, machine tool, 45 ° turning tool

Q:How many blades are there for cutting off a car knife? Which is the main blade, which is the blade?: Chisel edge cutting front end is the main cutting edge, flanked by vice cutting edge, have to do is take down the tool of measuring.

Q:What type of car can be made of the car with a smooth surface: The normal T15 is OK, mainly the Angle of grinding knife and the surface finish of the blade
