摘要： This invention pertains to methods and apparatus for polishing and planarization of workpieces, such as fiber optics connectors, metallographic samples, semiconductor wafers, microelectronic substrate, optical devices and the like. The polishing pattern is a hypotrochoid generated by a spur gear rotating inside of an internal gear. The hypotrochoid is a superior polishing pattern because it not only provides a pattern similar to a figure eight pattern for producing optimal polishing conditions, but it also appears to precess around the center of the polishing space and maximize the utilization of the polishing pad or film.

摘要： Chamfer processing is carried out by making plate material W end faces come in contact with rotating grinding belts. The grinding surfaces of the opposing side by side grinding belts are on the centerline in the thickness direction of the plate material. The center point is considered the pivot point as seen from the plate material end faces and in distance is smaller than the thickness of the plate material. Pivot motion of the plate material is carried out in the rotating direction of grinding belts. This chamfer processing method and device enables chamfer in a small curvature radius without applying a heavy tension load on grinding belts, and performs uniform deep chamfer processing of multiple plate material simultaneously.

摘要： The present invention includes a polishing pad or belt secured to a mechanism that allows the pad or belt to move in a reciprocating manner, i.e. in both forward and reverse directions, at high speeds. The constant bidirectional movement of the polishing pad or belt as it polishes the wafer provides superior planarity and uniformity across the wafer surface. When a fresh portion of the pad is required, the pad is moved through a drive system containing rollers, such that the rollers only touch a back side of the pad, thereby minimizing sources of friction other than the wafer that is being polished from the polishing side of the pad, and maximizing the lifetime of the polishing pad.

摘要： The polishing machine of the present invention is capable of improving flatness of work pieces. In the polishing machine, a carrier is formed into a thin plate having a through-hole in which a work piece is accommodated. An upper polishing plate polishes an upper face of the work piece. A lower polishing plate pinches the work piece with the upper polishing plate and polishes a lower face of the work piece. A driving mechanism moves the carrier along a circular orbit in a plane without revolving. With this structure, the upper and lower faces of the work piece, which has been pinched between the polishing plates, are polished by the polishing plates.

摘要： Means for producing reciprocatory movement of a vice carrier (18) across a guideway (17) mounted on a body moulding (11, 16), which partly shrouds a rotatably driven grinding wheel (14), comprise a rack moulding (57) having upper and lower racks (61, 62) which are alternately engaged by a pinion (44) driven from the grinding wheel drive, in use. Rack moulding movement is transmitted to the vice carrier and spring means (67, 68) move the rack moulding to change the pinion engagement from the lower rack to the upper rack and vice versa at the ends of the racks, thereby reversing the rack moulding movement. A guide peg (56) of the body moulding alternately engages in upper and lower slots (65a, 65b) of the rack moulding to maintain the pinion in engagement with its appropriate associated rack while it is between the ends thereof. The arrangement is intended for use as part of a releasable adapter for a powered grinding tool incorporating said grinding wheel.

摘要： A grinder wheel table feed apparatus converts rotation of a table driving motor into reciprocation movement of a grinder wheel table through a ball-screw mechanism to thereby impart a traverse movement to the grinder wheel table between a non-working position and a working position. The rotation of a reciprocation axle drive motor is converted through an eccentric cam into an oscillation movement of the grinder wheel table when the table is in its working position. A drive control system includes an encoder operable to read the rotational position of the reciprocal axle drive motor, and a control device effective to stop the eccentric cam at a predetermined eccentric angular position.

摘要： An instrument and tool honing mechanism in which a gear rack is mounted on and movable with a reciprocable bar, and a spindle having a pinion thereon is supported by a fixture in a transverse relationship to said bar with the pinion in engagement with the gear rack. A honing element is mounted on the spindle, and when the bar reciprocates, the rack creates a reciprocating movement in the spindle, and hence rotates the honing element on the spindle. The mechanism is preferably constructed as an attachment for a honing machine, and is capable of being readily mounted on and removed from the machine. The fixture preferably is pivoted to the rear of the reciprocable bar for angular movement from a position substantially horizontal to an elevated position where the pinion is disengaged from the gear rack. The honing element may be spherical or cylindrical shaped, and is normally mounted on a forwardly projecting end of the spindle where it can easily be used to recondition instruments and tools of the type normally used by dentists and doctors.

摘要： A planetary machining apparatus comprises a rotor and one or more drive spindle assemblies mounted thereon. Each drive spindle assembly includes a rotary spindle support mounted for rotation on the rotor about an axis parallel to and radially spaced from the rotor axis, a drive spindle eccentrically mounted on the spindle support for rotation about an axis radially spaced from the spindle support axis, and a machining element mounted on the drive spindle. A pair of bidirectional hydraulic motors are mounted on the rotor in operative engagement with the spindle supports for angularly adjusting the spindle supports to effect a radial displacement of the drive spindles and the machining elements relative to the axis of the rotor. A control arrangement including a rotary fluid distributor is provided for selectively operating the hydraulic motors during rotor rotation.

摘要： A single-slide, mechanically and electrically programmed grinding machine comprising a rigid enclosed base, a fixed workhead assembly on the base, a pair of parallel slidebars mounted on the base, and a wheelslide assembly mounted on the base for longitudinal displacement thereover. Longitudinal wheelslide displacement is mechanically controlled by a motor-driven cam bearing against a spring-biased lever pivoted to the base and connected to the wheelslide via a rod. Lateral feed is independently electrically controlled by a motor-driven nut and screw shaft assembly which angularly displaces the wheelslide assembly relative to one of the slidebars and about the centerline of the other slidebar. An eccentric and variable-position spacer is provided for reciprocating the wheelslide during a grind operation. A thermally-stable base configuration is disclosed. Part load and unload apparatus, all mechanically programmed, are also disclosed.
