Abstract: A method is provided for adjusting a handling machine (1) involves moving a control member (2) for controlling an actuator (7) or a motor (11) to adjust a maximum operating speed of the actuator (7) or motor (11) tool. The method includes memorizing a maximum speed setting in a suitable memory (4), and subjecting the work of the handling machine (1) to a control law, not exceeding the memorized maximum speed of operation. The method is applied of the adjustment method to a handling machine (1) including a plurality of actuators (7, 9, 11, 13, 15) and at least one actuator control member (2, 3).

Abstract: Disclosed is a blade grinder comprising a blade holder that is mounted so as to be rotatable about a horizontal shaft which is mounted so as to be rotatable about a vertical axis, thus allowing the blade to be optimally adjusted relative to a grinding disk. The grinding disk can preferably be vertically and horizontally moved using spindles. This creates a simple design allowing a lawnmower blade to be ground in a fully automatic manner.

Abstract: A grinding device includes a fixed barrel, a moving barrel, a grinding plate, and an actuator. The fixed barrel defines a chamber and includes a number of inner surfaces substantially parallel to a central axis, each of which defines a holding groove therein for holding a workpiece. The moving barrel is received in the chamber and includes a side surface substantially parallel to the central axis and defines an installation groove. The grinding plate is fixedly installed in the installation groove. The actuator is configured for driving the moving barrel to spin and move back and forth along the central axis, and driving the moving barrel to move towards a workpiece so that a surface of the workpiece is grinded into a desired arc surface by the grinding plate, and driving the moving barrel to move towards another workpiece after the desired arc surface of the workpiece is obtained.

Abstract: A polishing machine for polishing a periphery of a sheet of the present invention comprises a grinding shaft tilting mechanism (1) capable of changing a tilting angle of a rotary shaft of a grinding stone (3) with respect to a rotary shaft of the sheet (2) and also capable of changing its tilting direction. Accordingly, in a recess portion or a protrusion portion in the periphery, when the tilting direction is changed while the tilting angle is being maintained, chamfering (polishing) can be executed with high accuracy in the same manner as that of the outer circumferential portion of the sheet.

Abstract: Disclosed herein is a method including the steps of cutting a wafer to prepare a row block having a plurality of head elements arranged in a matrix, bonding a plate member to one side surface of the row block, bonding a row tool to another side surface of the row block bonded to the plate member opposite to the one side surface, and cutting the row block to prepare a row bar bonded to the row tool and having a row of the head elements. A bonding apparatus for realizing the above bonding steps is also disclosed.

Abstract: A face gear manufacturing operation wherein a set of oversized teeth are formed on a face gear or tapered pinion gear by a gear cutting operation. The oversized teeth are of a predetermined profile. The gear bearing the oversize teeth is then subjected to metallurgical surface hardening operation. At the conclusion of the heat treatment surface hardening operation, the face gear or pinion gear is subjected to a continuous grinding operation wherein a grinding wheel having a worm profile of a predetermined shape is rotated to grind the previously cut teeth to produce a finished tooth profile. The operation is CNC controlled. The gear producing apparatus requires only a slight modification to produce a face gear or a tapered pinion gear by the simple interchange of work heads.

Abstract: A lapping machine for lapping a row bar includes a lap plate for providing a lapping surface, a row tool having a plurality of bend cells formed by defining a plurality of slits, a pressure mechanism for pressing the row tool toward the lapping surface of the lap plate, and a bend mechanism for bending the bend cells of the row tool toward the lapping surface of the lap plate. The bend mechanism includes an air cylinder unit having a plurality of double-acting air cylinders, a plurality of racks operatively connected to the double-acting air cylinders, respectively, a plurality of drive pinions arranged coaxially and meshing with the racks, respectively, each drive pinion having a lever for driving the corresponding bend cell, a plurality of support pinions arranged coaxially and meshing with the racks, respectively, and a guide mechanism for guiding each rack, the respective drive pinion, and the respective support pinion in substantially the same plane.

Abstract: An apparatus for grinding a shank of a drill bit includes a base and several movable jaws supported by the base, that are movable toward each other and away from each other. A support ring is rotatably secured to the base, which has a central opening that encircles the movable jaws. A laterally adjustable grinding wheel support is secured to the support ring. Incremental rotation of the support ring results in incremental orbital movement of the grinding wheel support relative to the movable jaws. Lateral adjustment of the grinding wheel support moves the grinding wheel support toward and away from the movable jaws.

Abstract: A swing grinding fixture and process for using the same is disclosed that enables a conventional surface grinder to remanufacture a machine tool cutting insert by grinding a predetermined shape into the insert. A quick clamping insert holder coupled to a slide secures the tool insert in the fixture. A precision spindle cartridge is mounted in a rigid fixture body and coupled to the slide to provide the swing motion required to generate the radius to be ground. The rigid fixture body includes a pair of micrometer adjustable stops which limit the arc through which the slide may be swung and control the flank shape ground into the insert. In an alternative embodiment, a sine plate is attached to the fixture body and is used to incline the fixture to a predetermined insert rake angle. In operation, the grinding fixture is securely mounted to the table of a surface grinder and a cutting tool insert is secured in the insert holder.

Abstract: A device for producing inclines and/or grooves on friction pads, such as brake pads for motor vehicles comprises a table with a mount for the brake pads. The table is linearly moved on a carriage below flat, truncated-conical grind disks which are disposed in pairs and oriented mutually mirror-symmetrical. The table is swivellable about an axis oriented tranversely to the travel direction. The swivel movement is effected by at least one pneumatic cylinder. Control valves or control switches run onto cam ramps on cam bars when the table is driven forward and they initiate the swivel operation of the table. The friction pad is operated on when the table is in the downwardly or upwardly pivoted position, whereby the table is preferably locked in its position during the various grinding operations.
