Secured to the terminal end of the drive shaft is a deburring tool. A pivot-bearing is mounted in the housing adjacent the backwall. A connector extends from the backwall of the pneumatic motor and connects to the pivot bearing, thereby permitting the pneumatic motor to freely articulate radially in any direction while preventing free rotation about the bearing's longitudinal axis. A compliance device extends around the pneumatic motor at a location between the backwall and the deburring tool secured to the drive shaft. The compliance device restricts the movement of the pneumatic motor while applying a compliance force to the pneumatic motor as the pneumatic motor moves with the pivot bearing.

  • Patent number: 5277523
    Abstract: A precision depth spindle is mounted to rotate within a cartridge but is restrained against axial movement with respect to the cartridge. The cartridge is mounted for axial sliding movement within a housing, but cannot rotate with respect to the housing. A tool chuck is fixed to one end of the spindle for movement with the spindle, the tool chuck supporting a cutting tool. A spindle stop is mounted to the tool chuck and can rotate with respect to the chuck. This allows the spindle stop to be maintained stationary while the tool chuck and the cutting tool rotate. The spindle stop is finely adjustable axially with respect to the tool chuck, thus determining the depth to which the cutting tool will enter a workpiece. The cartridge has a limited axial motion range with respect to the housing, and both the spindle and cartridge are urged toward the workpiece with respect to the housing by a suitable spring or pressure means.

    Abstract: A handle-cutting device comprises a conveyor in the form of a horizontal table arranged to be rotated step-by-step to bring handle holders in turn to a handle-cutting station where the handle is lightly clamped. While the holder is stationary at the handle-cutting station, a rapidly rotating cutter (for example, rotating at 3,000 r.p.m.) having a contoured blade representing the profile of the wall of a cup bowl to which the handle is to be attached is progressively advanced towards the holder to remove surplus clay in thin slices from the handle. The blade is unconfined along those parts of its length which effect the cutting, being mounted on spaced apart supporting portions of a carrier, so that the small pieces of clay sliced away by the blade can escape from the cutter. The device ensures a high degree of conformity of the attaching surface of the handle to its intended configuration.

  • Patent number: 4180357
    Abstract: Corrugated tubing is advanced along its axial path by rotatably driven lead screw members the screw threading of which is in meshing engagement with the corrugations of the tubing, the lead screw members being in pairs with the screw threading of the members of each pair being of opposite hand and the lead screw members of each pair being rotated in opposite directions. The lead screw members of each pair present outwardly directed cutters which are synchronized substantially simultaneously to intersect the tubing thereby, in perforating the tubing, to restrain the tubing against rotation thereof about the axial path. There is also disclosed a method of producing the lead screw members with the outwardly projecting cutters mounted thereon.

  • Patent number: 4161641
    Abstract: An EDM process and apparatus capable of transversely displacing the electrode tool relative to the electrode workpiece according to a translation motion, while simultaneously linearly advancing the electrode tool relative to the electrode workpiece along a longitudinal axis. The process and apparatus of the invention consist in monitoring a machining dimension and comparing it to a predetermined parameter, and, as soon as such predetermined dimension parameter is achieved, sequentially retracting the electrode tool and re-establishing the feed of the electrode tool, while changing the radial direction of electrode translation motion between the beginning of the electrode tool retraction and the end of the electrode tool feed.
