Disk Adjusting Device of Polishing Machine

The present invention relates to a disc adjustment device for a polishing machine. The objective of the present invention is to have a wide thickness selection range of a metal material, and to use a disc for a long time, and to perform remote and fine adjustment of the disc as to the metal material during operation. The disc adjustment device is based on a polishing machine for removing foreign substances remaining on a surface of the metal material by rotating the disc installed at a disc axis, and can change a position of a disc axis and the disc further, in order to comply with thickness of the metal material and abrasion of the disc, by rotating a gear box where the disc axis is installed, within a limited angle range, by changing the position of the disc axis of an encoder axis clockwise or counterclockwise with a worm mechanism. The disc adjustment device is applied in the polishing machine.

DIAMOND TOOL FOR RIPAS SATURATION AND PROFILING PARTICULARLY OF ABRASIVE DISCS

Double end face truing device, double end face truing tool, and double end face truing method

First and second end surface truing sections are formed by protruding cylindrical first and second base bodies from opposite end surfaces of a disc-like base of an opposite end surface truing tool in the axial direction thereof and by providing on the external surface of the first base body and the internal surface of the second base body first and second abrasive grain layers in which numerous diamond abrasive grains are adhered with bond material. The rotational axis of the opposite end surface truing tool is inclined relative to the rotational axis of the grinding wheel within almost the same plane at a predetermined inclination angle. By moving the opposite end surface truing tool toward the rotational axis of the grinding wheel, the first and second abrasive grain layers respectively true the grinding surfaces at the opposite ends of the grinding wheel under almost the same condition to sharp grinding surfaces having moderate ruggedness, as they go ahead of the first and second base bodies to be backed up thereby. Consequently, it can be realized to true the grinding surfaces at the opposite ends of the grinding wheel under almost the same condition to the sharp grinding surfaces having the moderate ruggedness.

Grinder-stone dresser

Wheel dressing apparatus and method

WHEEL DRESSING APPARATUS AND METHOD ABSTRACT OF THE DISCLOSURE A method and apparatus for dressing adjacent faces on grinding wheel. A single point dressing nib and a rotary dressing wheel are mounted to a common slide oriented with its slide axis parallel to a first face on the grinding wheel. As the slide is actuated, the nib is drawn across the first face of the grinding wheel, dressing the entire face. After the single point nib traverses the first face of the grinding wheel, the rotary dressing wheel is activated and brought into engagement with a second face on the grinding wheel, adjacent to the first face. A cam is provided on the base which carries the slide, so that a tracing stylus will follow the shape of the cam and transmit the cam profile to the dressing nib as it traverses its path. In the manner, therefore, an extremely accurate profile may be dressed on a first face of the grinding wheel, and a second, potentially wear-causing face may be dressed into the grinding wheel by a dressing wheel yet the rotary dressing wheel will not introduce vibrational inaccuracies into the first face.

1354879 Tracing grinding wheels A A JONES & SHIPMAN Ltd and J HOULDSWORTH 14 Sept 1971 [15 Sept 1970] 43894/70 Heading B3D A device for adjusting a grinding wheel dressing tool unit 2 of a dressing apparatus in which the tool swivels about an axis, comprises means 57, Fig. 6, for supporting the unit, and an optical instrument 61 through which the cutting tip 1, or an image of the tip, can be viewed, the instrument having a sighting mark which represents the axis of tool rotation of the dressing apparatus, and the support being positioned relative to the instrument to simulate the position the tool unit occupies relative to the axis in the apparatus so that, viewed in the instrument, movement of the tool 1 relative to the sighting mark corresponds to movement of the tool relative to the axis of rotation in the dressing apparatus. In the dressing apparatus, the tool 1, such as a radiused diamond tip is mounted in a holder 2 axially adjustable by a screw (not shown) on a carrier 15 which, in turn, is adjustable transversely of the axis of the holder to a piston determined by abutment of an adjustable screw 30 or wedge 36 with a stop 32 on the arm 10 of a pantograph wheel dressing apparatus 13, the arm swivelling about a shank 11. To set the axial position of the holder 2 in the carrier and the adjustable screw 30 or wedge 36, the carrier can be removed from the arm 10 by release of a screw 23, and secured by a screw 23<SP>1</SP>, Fig. 6, to a pedestal 57 adjacent a pedestal 62 supporting the optical instrument which has a sighting mark preferably in the form of concentric rings, the screw 30 or wedge 36 abutting a stop 32<SP>1</SP>. The pedestals are adjusted so that the relative positions of the axis of the optical instrument and the surfaces 65, 66 of the pedestal 57 which engage the carrier are the same as the axis of the shank 11 if the wheel dressing apparatus and the surfaces engaged by the carrier on the arm 10. The cutting tip is ...
