Imported bearing manufacture with honing head of holes

Honing 2 ~ 30 MRRT NSK import bearing holes, grinding head body and oilstone seat becomes an organic whole, make up the core and the grinding head body on the whole length of surface contact, in order to enhance rigidity. 1) Single oil stone honing head as shown in figure 10. A 16 grinding head, suitable for processing and high requirement of straightness, aperture for 2 ~ j530mm hole, honing head by the two guide bar and a cutting of sharpening stone. Two leads to the asymmetric distribution, width of guide bar used to produce the oil stone under radial force and tangential force together ( Together with its supporting surface center) To prevent the deformation of honing head. The narrow orientation of auxiliary supporting role, making the honing head and contact state stability of the hole, in order to improve machining accuracy. Orientation of the materials with hard alloy, or synthetic diamond. Article according to the aperture size, orientation, but make it Mosaic or with plating diamond micro powder coating, on the surface of the grinding head surface can also be plated on coarse-grained diamond, then using cubic boron nitride or oil stone to be dull, lose its cutting ability. 2) Split shell honing head consists of two semicircular bearing shell, is suitable for processing the straightness to demand higher, hole with discontinuous surface. Radial expansion of honing head up feed is applied to two semicircle through wedge up core bearing shell on the inclined plane of retraction is to rely on two o-ring at the ends of the axial spring coil spring. It can use ordinary abrasive abrasive adhesive on the surface of the grinding head, also can use a few root diamond abrasive with low melting point electrode welding on the surface of the grinding head. Sharpening stone length is generally honing head chooses twice the length of sharpening stone. The grinding head is convenient for cutting surface on the grinding machine grinding it, NSK bearings imported machining precision is stable and the cutting efficiency is about 10% higher than the single oil stone honing head and long service life. 3) Adjustable whole honing head using the honing head in mass production to processing high precision hole. The following 5 gm, size error can be controlled within 2 ~ 3 PM, the surface roughness R. 2 PM. 5 mm thickness of diamond grits, grinding head in the hole for the 1:50 cone hole. Away L of cones in the cone up core make whole produce elastic deformation of grinding head and adjust to the size of the book. In the process of import bearing no increases and movement, and thus can be thought of as a forming tool. Are the use of the honing head machine, usually more than vertical shaft multi-station honing machine. For the rigid connection between honing head and spindle, workpiece fixture design into floating forms. The movement with general honing honing head, grinding head make rotation movement on the one hand, on the one hand, the radial fast close to the workpiece, the axial feed ( 5 m/min) , quick return. A work cycle can complete a processing. Big hole honing head, it is mainly used for large aperture of honing processing, for the convex ring type big hole honing head, close to honing away L convex ring diameter size. To support oil stone, and inherit the honing cutting force, has a good rigidity. Oilstone seat of horizontal pin 3 clingy convex ring end face, axial positioning for sharpening stone and honing under axial force, moving cone made oilstone seat 2 out of 5, borrow the spring coil 1 retract a sharpening stone.
