The saw blade milling cutter processes the quenching parts and cuts, and what material milling inser

The most common cemented carbides on the market are K10, K20, ultrafine particle Z10, ultrafine particle Z20, impact resistant V40, impact resistant V50 and so on. First of all, K10 material has good wear resistance, low toughness, practical hardness, and is suitable for general milling machine processing. For wet cutting, micro feed, micro notch machining; The wear resistance and toughness of K20 material are the same as those of K10, and the practical hardness; Ultrafine particle Z10 and Z20 materials are also good wear resistance and low toughness, with the following ultrafine particle WC alloy, with the same hardness as general cemented carbide, and at the same time has high toughness.

Machining such as small feeds, small cuts, and low-speed cutting can give full play to its high performance. Their practical hardness is the former and the latter; Impact-resistant materials V40 and V50 also have good wear resistance and low toughness. Alloys with medium and coarse particles in the WC range are suitable for processing with these two requirements due to their toughness and impact resistance.

Practical hardness of the former and the latter.

Part 1 Common Gear Materials.

Common gear materials include 20CrMnTi, 16Mn CrMo, etc. Usually these gears are used after heat treatment, and the hardness after heat treatment is generally above HRC45. Common types of gears are automotive gears, pressure vessel gears, and traction machine bull gears.

The second part of the gear processing technology.

Generally, the raw materials are made into coarse blanks, and then the gears are basically formed by CNC lathe processing, and then reprocessed, turned, and ground after heat treatment. The general hardness of the heat-treated gear can reach HRC58 62, which is difficult to machine, so it is particularly important to choose the right tool to turn the gear.

The third part of the selection of gear cutters for hard turning.

The hardness of the gear after heat treatment is higher than HRC50, in the past, the hardness of the gear after annealing is generally reduced to process, with the development of the tool, CBN superhard tool has been able to meet the needs of the tool, and the common CBN tool materials for machining quenched gears include:

The fourth part is the recommended cutting parameters for the gear after machining quenching.

After quenching, the selection of appropriate cutting parameters for gear processing is the guarantee to ensure the final effect of CBN tool processing, and the following are the recommended cutting parameters for KBN100 and KBN200 when machining gears:

Part 5: Common tool use cases for machining gears.

1) KBN100 grade CBN insert continuous finishing gear bore.

2) KBN200 grade CBN inserts intermittently turn gear end faces.

Part VI Summary.

To sum up, KBN100 and KBN200 are ideal tool materials when finishing and machining quenched gears, and it is recommended to consult relevant tool technicians to choose the right tool grade when rough turning quenched gears.

YS2T saw blade milling cutter for machining quenched parts (stainless steel).

Determined by s=vc (blade diameter). Extended introduction: The product is made of integrated cutter body and cutter teeth with buried rolling structure.

Solid welded teeth are made of tungsten carbide or other wear-resistant cutting tool materials and brazed to the cutter body. The toothed cutter teeth are fastened to the cutter body by the method of mechanical clamping. This interchangeable tooth can be either a solid tool material or a welded tool material.

The milling cutter with the cutter head mounted on the cutter body is called internal sharpening; The cutter head is sharpened separately on the fixture and is called external sharpening. Indexable (see indexable tools): This structure has been widely used in face mills, end mills, and face and face mills.

Product Category: Sharp-tooth cutters grind a narrow cutting strip on the flank face to create a relief angle, which has a high life due to the reasonable cutting angle. There are three types of tooth backs for sharp-tooth milling cutters: straight lines, curves, and polylines. Straight tooth backs are often used for finishing milling cutters with fine teeth.

The curved and polygonal tooth backs have better tooth strength and can withstand heavier cutting loads, and are often used for coarse tooth milling cutters. The back of the tooth milling cutter is processed into the back of the Archimedes spiral by the shoveling (or shovel grinding) method, and the skin liquid slip mill only needs to be re-ground in front after being blunt, and the original tooth shape can be kept unchanged, and it is used to manufacture various forming milling cutters such as wax gear milling cutters. 0

Different carbides have different recommended linear speeds for use VC, which can be determined based on S=VC (*blade diameter).

In China, the national standard for solid carbide saw blade milling cutter is GB T 14301-2008 "Solid Carbide Saw Blade Milling Cutter", which replaces GB T 14301-93, and the standard stipulates the basic requirements of the type and size, appearance, surface roughness, position tolerance, material, hardness, logo and packaging of solid carbide saw blade milling cutter.

At present, this carbide saw blade milling cutter standard is only applicable to carbide saw blade milling cutters with an outer diameter of 8mm-125mm.

The dimensions in the standard of saw blade milling cutters include: outer diameter, inner hole, thickness, number of front angles, number of back angles, back width, tooth depth, flute arc and flute angle. There are special regulations for the declination angle of the outer diameter of more than 80 mm, which is to make a "step" as the saying goes.

In general, the rake angle of the cutter teeth is 0-5° and the rear angle is 11-13°. Thickness tolerance: 63 outer diameter below +, 63-125mm outer diameter thickness tolerance is +.

The standard marking method of the saw blade milling cutter is: outer diameter * thickness * inner hole * number of teeth.

Excerpted from the technical article of Ruizheng Precision Tools.

This criterion is too late. It only briefly describes the basic material and the one-tooth data of the triangular tooth, and the tooth shape is only defined from the perspective of geometry, and does not involve in technology, metal cutting, mechanics and other related technologies, especially with the emergence of arc-toothed tungsten steel saw blades, it is impossible to apply it originally.

Engraving high-quality arc toothed tungsten steel saw blade.

The selection of the cutting amount of the machine tool must be within the range of the main drive power, feed transmission power and spindle speed range and feed speed range of the machine tool. The rigidity of the machine-tool-workpiece system is an important factor limiting the amount of cutting required. The amount of cutting should be selected so that the machine-tool-workpiece system does not have a large "chatter".

If the thermal stability of the machine tool is good and the thermal deformation is small, the cutting amount can be increased appropriately.

Tool The tool material is an important factor that affects the amount of cutting used. Table 6-2 shows the performance comparison of commonly used tool materials.

The tools used in CNC machine tools mostly use indexable inserts (machine clamp blades) and have a certain life. The material and shape of the machine-clamped insert must be adapted to the cutting speed and feed in the program and stored in the tool parameters. Please refer to the relevant manuals and product brochures for the specifications of standard blades.

Workpiece Different workpiece materials should be adapted to the tool material, blade type, and machinability. Good machinability is marked by efficient chip formation at high cutting speeds, with less tool wear and better surface finishing. Higher cutting speeds, smaller back-feed and feeds, and better surface roughness can be obtained.

Reasonable constant cutting speed, small back feed and feed can obtain high machining accuracy.

Coolant Coolant has both cooling and lubricating functions. It takes away the cutting heat generated by the cutting process, reduces the temperature rise of the workpiece, tool, fixture and machine tool, reduces the friction and wear between the tool and the workpiece, and improves the tool life and the surface processing quality of the workpiece. With coolant, it is often possible to increase the amount of cutting.

Coolant must be changed regularly to prevent corrosion of machine rails or other parts, especially water-soluble coolant, due to its age.

This problem is relatively wide, and the easiest solution is to take a more authoritative tool manufacturer's product brochure to view.

Different processed materials, different tool specifications, and different tool types have different optimal cutting parameters, so it is recommended that you go to the product brochure of foreign tool manufacturers (such as SECO, ISCAR, SANDVIK, etc.) to find it directly, because this is not something that can be explained in one or two sentences.

There is no specified value for this, depending on the material of the workpiece and the material of the tool, and the flexible use of the machining industry must know how to be flexible.

Hello, milling cutter flying head milling quenching parts need to use high hardness, high wear resistance inserts. Typically, CBN (modified cubic boron nitride) inserts or PVD-coated blades are used. CBN inserts are one of the most widely used blades at present, its hardness is more than 2 times higher than that of tungsten steel, and it has excellent wear resistance and corrosion resistance, so it is suitable for machining high-hardness materials and quenched parts.

PVD coated blades are coated with a metal film with a thickness of only a few microns, which can improve the hardness and wear resistance of the blade, reduce the cutting force and friction coefficient, and improve the efficiency of nuclear land processing.
