A magnetic chip conveyor of the present invention reduces the possibility that both end portions of a long chip are adsorbed by two or more types of magnets having different magnetic forces, so that a long chip does not remain. An endless chain is disposed on the rear surface of a plate, so as to be wound around sprocket wheels. The sprocket wheel is rotated in the counterclockwise direction by a motor, and the endless chain rotates in the counterclockwise direction. Twelve magnet holders are fixed to the endless chain at equal intervals. Three types of permanent magnets having different magnetic forces are bonded and fixed to the magnet holders.

A fabric cutting system and/or method can include a mandrel having a body and first and second legs, a chuck, the chuck configured to receive either one of the legs or body to rotatingly support the mandrel. The mandrel can be rotated and the fabric mounted on the mandrel can be cut about the leg at a location beyond the end of the other leg. One of the legs can include a leg extension removable from a leg base that when removed allows the other leg to be cut beyond the end of the leg base. The fabric can be cut with a cutting laser, which may be a multi-axis laser, and/or have low power.

The present invention is a novel machine for repairing damaged wheel rims whereby the machine is a combination CNC and manual lathe configured of performing all of the required tasks for repairing damaged wheel rims in a single unit.

A tool quick-stop device for a lathe has a base, bottom plate, front side plate, rear side plate, right side plate, left side plate, top fixed plate, tool bar, cam lever, buffer spring, cylindrical guide rail, adjusting nut, first locking nut, double end stud, second locking nut, pressure spring, pressing plate, hold-down bolt and pin shaft. The cam lever supports the tool bar before tool falling. When tool falling is required, the cam lever is rotated through external force. When the cam lever rotates over a certain position, the tool bar instantaneously loses supporting force. Under strong pressure of the pressure spring, the tool bar falls the tool with great acceleration and is separated from the cutting region in a short period of time and the cutting root is frozen.

In one aspect, a machine tool having a frame assembly, a first head having a first rotatable workpiece holder, and a second head having a second rotatable workpiece holder. The frame assembly includes a first door movable in a first direction between a first closed position and a first open position and a second door movable in a second direction transverse to the first direction between a second closed position and a second open position. The frame assembly has an access opening sized to permit access to the first and second heads with the first door in the first open position and the second door in the second closed position. The frame assembly has a larger access opening to increase ease of user accessibility to the first and second heads with the first door in the first open position and the second door in the second open position.
