Honing 2~30mrrt NSK bearings of small holes, grinding head and body become one with stones, make up core and wear on the head and body throughout the length for contact to enhance rigidity.
1) Shi Heng oil mill shown in the first figure of 10,116 grinding head, suitable for processing lines of holes is very high, the aperture is 2~j530mm, honing head consists of two roots-oriented and composed of a cut stone. Two roots-oriented asymmetric distribution, the width guide to bear oil stone of radial and tangential forces (resultant force through its seating in the middle), prevention of honing head deformation. Narrow-oriented secondary support role, contact State stability of honing head with holes to improve machining precision. Guidance material using carbide or diamond. According to the aperture size, orientation can be inlaid or diamond powder by the electroplating method of plated grinding head surface, and can also be coated coarse-grained diamond and cubic Boron Nitride grinding wheels or stones to abate it, make it lose their cutting ability.
2) outside bearing type of honing head made up of two semicircular Bush, suitable for processing high linearity requirements, continuous surface of holes. Radial expansion of honing head rises feeding through wedge-shaped rising core role in two semicircular on a bearing of bevel, retract is axial two spring-o-rings at each end of the elastic. Common abrasive stones available adhesion in the grinding head surface, also available a few diamond oil stone with the low melting point of covered electrode welded to the grinding head surface. Stone length is generally attached to the honing stone twice times the length. This grinder for grinding machine grinding it on the cutting surface, NSK bearings manufacturing precision and stability, Shi Heng cutting efficiency than single oil around head high 10%, the service life is long.
3) overall honing head can be adjusted with honing head to this process in the mass production of high-precision hole. Hole shape errors of up to 0. 5gm, size error within the 2~3pm, surface roughness r. Up to 0. 2pm。 Grinding head and body as a whole sleeve, symmetrical opening two axial grooves on both sides. Its surface coating on 0. 3~0. 5mm thickness of diamond abrasive, grinding head hole in the body to 1:50 tapered hole. Cone-lonely in the l cone rising core elastic deformation of the grinding head and body as a whole, adjusted to predetermined dimensions. There is no increase in the processing of imported bearings and contraction, so it can be thought of as a prototyping tool. This honing machine tools are generally multi-position progressive honing machine is the vertical axis. Honing head and rigidity of spindle to join, workpiece clamp designed to float. Honing head movement and honing of the General movement of different grinding head for rotational motion, radial fast approaching the workpiece on the one hand, axial feed (feed rate to 1~1. 5m/min), quickly returned. A work cycle to complete a process.
Honing head, mainly for big bore honing, convex ring honing head, convex ring outer diameter close to the honing of lonely l size. In support of the whetstone and bear grinding cutting force, has good rigidity. Stone cross pin 3 on the seat close to the convex face in the ring, to the axial position of stones and honing under axial force, cone 5 stone moved up 2 out, take 1 retracting spring ring stone.
