| A grinding machine utilizing multiple, parallel, endless, abrasive belts for simultaneously grinding several surfaces on a workpiece, such as cam lobes on a cam shaft. The grinding machine includes a contouring head assembly comprising a plurality of contour feed units, each contour unit including a curved back-up shoe, a back-up shoe holder, an adaptor for mounting the shoe holder, and a ball-spline mechanism is secured to the adaptor for transmitting power from a drive motor to the back-up shoe to press an abrasive belt, associated with the back-up shoe against a workpiece. A locating lip is defined on each adaptor, and a reference pad is established on the contouring head assembly. The adapters are divided into an upper and lower row, and the locating lips are formed oversized. One row of lips is ground to a desired distance from the reference pad, and the other row of lips is then ground relative to the previously ground row of locating lips. The back-up shoe holders are then secured in position upon the locating lips. The method of assembling the machine, the enclosure that encompasses the rear face of the contouring head assembly, the laterally movable support bracket for the drive drum assembly, and several other complementary features, coact to provide a grinding machine that functions efficiently while maintaining tolerances previously unobtainable with multiple belt grinding machines. | ||||||

| 173 | Tapered bearing for drive drum assembly of grinding machine utilizing multiple, parallel abrasive belts | US363330 | 1994-12-23 | US5529531A | 1996-06-25 | Russell E. Kaiser, Jr.; Ricky L. Mowen; William W. Pflager; Dennis F. Rice |
| A tapered bearing for the drive drum assembly of a belt grinding machine that employs multiple, parallel, abrasive grinding belts, and back-up shoes for pressing the belts against the surfaces on a workpiece to be ground. The drive drum assembly, in cooperation with small pulleys operatively associated with the contouring head, keeps the abrasive belts properly trained. The central shaft of the drive drum assembly, which has a plurality of large pulleys and spacers positioned therealong, is secured between a fixed bearing support and a laterally movable support bracket. A tapered bearing is fastened to one end of the central shaft, and a complementary shaped aperture is defined in a spindle retained in the movable support bracket. When the movable support bracket is shifted inwardly, by the hydraulic circuitry of the grinding machine, the tapered bearing fits snugly into the aperture so that the drive drum assembly is supported in a rigid, sag-free manner. The snug fit "pre-loads" the drive drum assembly and bearing assembly, so that such assemblies rotate smoothly, without slippage, when the drive belt delivers power to the drive drum assembly. Seals are provided about the tapered bearing so that dust and debris cannot degrade the bearing, and the bearing does not wear excessively, even under prolonged, high speed operation. | ||||||

| An abrasive tape comprises a flexible substrate and an abrasive layer which is overlaid on the flexible substrate and which contains abrasive grains and a binder. The abrasive grains comprise first abrasive grains, which have a mean grain diameter falling within the range of 0.07 .mu.m to 0.40 .mu.m and a Mohs hardness falling within the range of 5 to 7, second abrasive grains, which have a mean grain diameter falling within the range of 0.20 .mu.m to 0.60 .mu.m and a Mohs hardness not lower than 8.5, and fine diamond grains, which have a mean grain diameter falling within the range of 0.5 .mu.m to 3.0 .mu.m. The abrasive tape is used during a polishing process on a laminated type of magnetic head, which is constituted of a nonmagnetic substrate, a magnetic material, and a glass bonding agent. The abrasive tape is suitable for the polishing of magnetic heads, which are to be used for high-density recording with the shortest recording wavelengths of approximately 0.8 .mu.m, and has a high polishing performance. | ||||||
| 175 | Locking mechanism for contouring head assembly for multiple belt grinding machine | US953798 | 1992-09-30 | US5359813A | 1994-11-01 | Russell E. Kaiser, Jr.; Steven G. Lueckeman |
| A locking mechanism for the contouring head assembly of a belt grinding machine that employs multiple, parallel, abrasive grinding belts, and back-up shoes for pressing the belts against the surfaces on a workpiece to be ground. The locking mechanism secures the contouring head assembly to the bed of the grinding machine. The locking mechanism includes a protrusion, such as a ball, that is carried by the contouring head assembly and a pivotable arm with a socket defined near its free end. The pivotable arm is secured to a shaft that is driven by a rotary actuator, that is powered by a hydraulic motor. The socket engages the protrusion to securely support one side of the contouring feed assembly. A hydraulic cylinder forces a tapered plunger against the pivotable arm to enhance the locking action. | ||||||

| 177 | Computer controlled grinding machine for producing objects with complex shapes | US838942 | 1992-02-21 | US5193314A | 1993-03-16 | David Wormley; Edward A. Agranat |
| A grinding machine is particularly adapted to produce blades and buckets of the kind used in turbines and other objects having complex curved surfaces. Data blocks representing the surface of the object to be created are stored in a computer that controls the machine to finish a rough blank into the final object. An abrasive belt passes over a nose roller to make a line contact with the workpiece. The belt and the workpiece are subject to six computer-controlled degrees of freedom: three in translation and three in rotation. The supporting arm of the nose roller can be moved angularly about the belt contact point while the nose roller can be adjusted about a perpendicular axis through the contact point of the belt. Feedback controls indicate the position of and the motion velocity about the six axes. A positional feedback indicates the precise position of the workpiece at the finishing point to permit automatic compensation for belt wear. | ||||||

| A control apparatus for controlling the amount of grinding of a belt material in a grinding machine wherein, for example, in the production process of making belts, a cylindrical belt material is ground on its back to finish its thickness to a standard dimension. The controlling apparatus is provided with a feed apparatus for feeding either the grinding member or the work to be ground to force it into contact with the other, a cam apparatus for regulating the feed stepwise up to the preset maximum feed position, and a thickness presetting means for presetting the final thickness of the work to be ground in the maximum feed position of the grinding member controlled by said cam apparatus. The control apparatus is capable of grinding reliably a work to be ground to a preset thickness, and the finishing thickness of the work to be ground can be altered with ease. | ||||||

| 180 | Profile grinding machine and method | US546307 | 1990-07-03 | US5127195A | 1992-07-07 | Juergen Heesemann |
| A profile grinding machine has at least two tool holders which are fixed in a frame and on each of which is fixed a grinding tool, for machining workpieces transported past the profile grinding machine in a working plane. The tool holders can be arranged in various angular positions, and their tools complement each other to give the desired profile shape. The advantages of a uniform grinding operation can be achieved in spite of the use of a plurality of tools by arranging the tool holders at essentially the same height in the transporting direction and by the tools of two neighboring tool holders forming the desired profile shape by a complementarily toothed design of the mutually facing edges, one engaging in the other. | ||||||
