Vit CBN Grinding Wheel For Gear Hob Grinding

CBN super hard grinding wheel for hob deep hole grinding


We customize the production of a special gear wheel hob hole, broach hole with cubic boron nitride CBN grinding head (grinding wheel).

Diamond and CBN cubic boron nitride wheels are used for end grinding. The outer circle is very thin and can be ground to the bottom of the cutting edge.

The two materials of grinding wheel wear resistance is very good, low loss during grinding, suitable for dry grinding environment and wet grinding environment.

The commonly used granularity is 60 mesh, 80 mesh, 120 mesh, 150 mesh and 180 mesh (the knife edge with high finish requirements can be customized finer granularity), the coarser granularity grinding will be more sharp, the knife edge finish is slightly worse.

Finer grain is the opposite.

The external diameter of grinding wheel is from 50mm to 500mm, which can be customized according to different requirements of customers and processing technology design.

Application of Vit CBN Grinding Wheel For Gear Hob Grinding

Gear hob used in processing gear, sprocket, turbine and spline etc., to withstand the effect of impact load and in the manufacturing process of wear and tear, so the hardness requirements to HRC63-66 degrees, the material is commonly high speed steel (such as W18Cr4V W9Mo3Cr4V, W6Mo5Cr4V2, etc.).

Why choose Vit CBN Grinding Wheel For Gear Hob Grinding

The inner hole of high speed steel hob will be deformed after carburizing heat treatment. The unilateral deformation will range from 0.1 mm to 0.25 mm, and the surface hardness can reach above HRC60 degrees.

After heat treatment, the surface hardness of hob is relatively high. Usually, grinding wheel is used for inner hole grinding in the later stage.

General high speed steel hob body is relatively long, the hole is relatively deep (such as hole depth in 150 mm to 200 mm, some may exceed 200 mm depth).

Grinding with corundum grinding wheel will encounter excessive wear of grinding wheel, difficult to master the size, hole grinding out will have the problem of taper.

It is recommended that users use cubic boron nitride (CBN) grinding wheel to grind holes.

Wheel hob grinding inner hole of cubic boron nitride (CBN grinding wheel) there are several different processes of producing method, this is according to customer's specific process to set, such as the use of grinding machine is high speed or low speed grinder, in theory belongs to low speed grinding machine speed is lower than 10000 turn, more than 40000 to a high speed, another factor is hob grinding inner hole machining allowance and finish requirement.

Different machining processes have different processes of grinding wheel to deal with, there is no general only applicable.

Choosing the wrong grinding wheel will result in low processing efficiency, long processing time and taper of the deep hole grinding.

Our company can provide suitable CBN grinding wheel according to different hob aperture, depth and finish requirements and different types of grinding machines. Welcome to consult.

Advantages Of Our Vit CBN Grinding Wheel For Gear Hob Grinding

Our company produces single beveled diamond grinding wheel (suitable for grinding carbide hob) and CBN cubic boron nitride grinding wheel (suitable for grinding high speed steel hob of various materials) for hob grinding.

The working layer width of the grinding wheel of the two materials is generally between 3mm-5mm, and the thickness is between 2mm.

(this design is because the hobbing blade tooth is short, and the narrower the working layer of the grinding wheel, the sharper the grinding will be. The wider the grinding resistance will be, and the worker will feel that the grinding of the grinding wheel is not sharp.)

Grinding wheel Angle is generally around 15 degrees (special requirements can be customized).

Cubic boron nitride CBN for short, belongs to the superhard material, hardness is second only to diamond, good heat resistance, made after grinding wheel grinding performance, not only qualified for grinding hard materials processing, improve the production efficiency, and to strictly control the shape and size precision of the workpiece, can effectively improve the quality of grinding workpiece, improve workpiece surface integrity after grinding, thus increasing the fatigue strength of the parts, prolong the service life and increase the reliability.
