| 108 | High speed precision drilling system | US853662 | 1986-04-18 | US4761876A | 1988-08-09 | Wojciech B. Kosmowski |
| A high speed drilling system is disclosed for high speed drilling of very small holes in workpieces such as printed circuit boards. The X-Y positioning system includes air bearings to provide lift between the stationary guide beams, the crossbeam and the top table, and further includes a vacuum preloading apparatus for providing a preloading force between the table and the guide beam. The preload force dampens Z axis oscillations which can result in drill bit breakage. The top table is a lightweight honeycomb structure, whose effective rigidity is virtually that of the guide beam due to the vacuum preloading. The system includes pairs of spindles, one a conventional spindle for drilling holes larger than about 0.125 inches, and the other a high speed spindle for drilling holes in the range of about 0.003 to 0.125 inches. The high speed spindle includes a stationary spindle body carrying the stator of the rotary drive motor. Only the spindle rotor is translated along the Z axis to perform the drilling movements. The rotor is supported within the spindle body by rotary and linear air bearings, and is axially driven by a linear motor. A toolchanger loaded by clips carrying the drilling bits is mounted on the top work table, and minimizes the time required to change drilling tools. The clips minimize the manual handling of the fragile drill bits. A vacuum hold-down apparatus is employed to secure the workpieces to a drilling station. | ||||||

The tube has retractable pins located adjacent the open lower end for selectively depositing individual point support members from the tube onto the cutting surface of the cutting table so that the individual point support members are positioned on the cutting surface of the cutting table to support workpieces according to the size and shape of metal parts to be cut from the workpieces. | ||||||
| 113 | Mechanism for lathe-working articles | US602433 | 1984-04-20 | US4553295A | 1985-11-19 | Hermann Dietrich |
| A mechanism for the lathe-working of longitudinal, cylindrical, or slightly conical work-pieces (88), preferably cartridge cases for firearms, which uses at least two driven rotating spindles (80) located in a housing (17). The housing (17) is rotatable around an axle (16) and is rotated by a hydraulic or pneumatic cylinder (22, 23) into a series of operating positions. Tools for working the cartridge cases (88), (a) a shaper for the extractor groove (93) and the extractor flange (92) and (b) a cut-off piece (103), are both attached to a cut-off sled (101). This cut-off sled (101) is guided back and forth on a main sled (94) laterally with respect to the axis of rotation of a spindle (80). The main sled itself may be moved in the direction of the axis of rotation of the spindle (80). In this manner, the length of the cartridge case is determined exactly. Furthermore, each rotating spindle (80) is driven individually. Through use of a clutch (67), each rotating spindle can be selectively connected to a drive motor. In this way, only one rotating spindle is driven at any particular time while the others are not driven. Thus, the loading time is shortened and the loading process simplified. | ||||||

| 115 | Apparatus for drilling, engraving and carving ophthalmic lenses | US633513 | 1984-07-23 | US4541760A | 1985-09-17 | Georges Zoueki |
| A multipurpose apparatus for drilling, engraving and carving ophthalmic lenses. The apparatus comprises a base in which is mounted an electrical motor, and a tool holder is connected to the shaft of the motor for detachably mounting a drilling, engraving or carving end mill above the upper surface of the base. A working support is also mounted on the upper surface of the base for maintaining and supporting the lenses in the various positions in which they must stand in order to be easily drilled, engraved or carved. The working support comprises a platform detachably mounted onto the upper surface of the base, and a guide holder rigidly mounted onto the platform in parallel relationship with respect to the tool holder. The support also comprises a L-shaped tube having one end fitted into a central hole provided in the platform for giving room to the tool holder, and the other end connected to the guide holder. The tube has an upwardly extending portion with an internal diameter and a height sufficient to receive the tool holder while allowing the end mill mounted thereon to project outwardly from the tube through a small opening. The tube also has a perpendicularly extending portion from the upper surface of which projects the end mill, this upper surface being useful for supporting a lens when the same is drilled, engraved or carved with the end mill. The apparatus may advantageously be connected to a vacuum source for sucking out particles resulting from the drilling, carving or engraving operation through the small opening from which projects end mill and the upwardly expanding portion of the L-shaped tube. The apparatus may also comprise one or more lens guides adjustably mounted onto the guide holder for laterally guiding or retaining the lenses with respect to the end mill. | ||||||
