1) single-oil Shi Heng grinding head, suitable for processing linearity is very high, the aperture is 2~j530mm hole, honed by two guide bars and consisting of a cut stone. Two roots-oriented asymmetric distribution, width guide bars used to withstand the radial force of the whetstone and tangential force (Heli by seating in the middle of it) to prevent deformation of honing head. Narrow-oriented secondary supporting role, contact State stability of honing head with holes to improve machining precision. Oriented material carbide or diamond. According to the aperture size, orientation can be made into mosaic or electroplating diamond micro-powder coating on the surface of grinding head can also be coated with coarse-grained diamond and cubic Boron Nitride grinding wheels or stones to abate it so that it lost the ability to cut.
2)-Folio bearing honing head consists of two semi-circular Bush form, suitable for processing high linearity requirements, continuous surface holes. Honing head radial expansion rise feed through wedge-shaped rising core roles in two semi-circular bearing on the slope, retract is axial two spring o-rings at each end of the elastic. Common abrasive stones bonded to the grinding head surface, can also be used a few diamond electrode welding of oil stone with a low melting point on the surface of grinding head. Stone length for honing whetstone twice times the length of the selection of the head. On the grinder this grinder for grinding the cutting surface, bearing precision stability, cutting efficiency than about single-oil Shi Heng grinding head 10%, the service life is long.
3) can be adjusted overall honing head in mass production using this kind of honing to precision machining of the hole. Hole shape errors of up to 0. 5gm, size error can be controlled within 2~3pm, surface roughness, r. Up to 0. 2pm。 Grinding head and body as a whole sleeve, axial slot for two symmetrical on both sides. 0-coated on its surface. 3~0. 5mm thickness of diamond grits, grinding taper hole in the body to 1:50. Cone larvicidal l conical rise cores make the elastic deformation of grinding head and body as a whole and adjust to a predetermined size. In machining process of bearing does not rise and contraction, it can be seen as a tool for forming. Use this honing head of machine tools are generally multi-position progressive honing machine for the vertical axis. Honing head with rigid connection between the spindle, workpiece clamp designed to float. Honing head movements are different from general campaign honing, grinding head for rotational motion, radial closing fast on the one hand the workpiece axial feed (feed rate to 1~1. 5M/min), quickly returning. A duty cycle to complete a process.
