摘要:
A rare earth magnet block is cutoff machined into pieces by rotating cutoff abrasive blades. Improvements are made by setting the blades on one side of the magnet block, rotating the blades, starting machining operation to form cutting grooves in the magnet block from one side, interrupting the machining operation, moving the blades to the other side of the magnet block, and restarting the machining operation to form cutting grooves in the magnet block from the other side, until the cutting grooves formed from the one and other sides merge with each other.

In a method for multiple cutoff machining a rare earth magnet block, a cutting fluid feed nozzle having a plurality of slits is combined with a plurality of cutoff abrasive blades coaxially mounted on a rotating shaft, each said blade comprising a base disk and a peripheral cutting part. The slits in the feed nozzle into which the outer peripheral portions of cutoff abrasive blades are inserted serve to restrict any axial run-out of the cutoff abrasive blades during rotation. Cutting fluid is fed from the feed nozzle through slits to the rotating cutoff abrasive blades and eventually to points of cutoff machining on the magnet block.

The data destruction machine is a desk-top, portable unit with a short (under 10 second) cycle time, pluggable into a wall outlet. Upon insertion of a disk (such as a CD or split DVD) into the machine, which is fully automatic, data is removed. The machine converts the data-storage layer into residue consistent with security destruction standards from which no data is retrievable. A single machine may be used for declassifying CDs and split DVDs. Splitting DVDs in preparation for inserting them into the data destruction machine may be accomplished quickly and simply.

A sintered magnet sawing apparatus is provided comprising a cylindrical work carrier mounted on a horizontal rotating spindle and having a regular polygonal shape in a perpendicular cross section, and a plurality of endless elastic belts adapted to force a work of sintered magnet against the carrier surface to secure the work thereto and adapted to travel synchronously with and counter to the rotation of the carrier in a circulatory manner. In accordance with rotation of the carrier, the work is delivered to the peripheral surface of the carrier, secured thereto by the elastic belts, moved further forward and cutoff machined by an outer cutoff blade. The divided work is moved further forward, released and discharged from the carrier.

In certain embodiments, a system is provided for the efficient removal of an old grip from a fishing pole while maintaining the integrity of the pole. The system can include a removal portion including one or more rotational assemblies that rotate one or more grinding members. The grinding members can include a rotational blade with a centering rod. The rotational assembly can remove the old grip while maintaining the integrity of the rod within. The system can include multiple sets of grinding members that are organized for efficient identification or may include adjustable grinding members that can be configured for specific rods. The system can further include a guide to help identify particular grinding members for use with particular fishing poles.

A rare earth magnet block is cutoff machined into pieces by rotating a plurality of cutoff abrasive blades. Improvements are made by starting the machining operation from the upper surface of the magnet block downward, interrupting the machining operation, turning the magnet block upside down, placing the magnet block such that the cutoff grooves formed before and after the upside-down turning may be aligned with each other, and restarting the machining operation from the upper surface of the upside-down magnet block downward until the cutoff grooves formed before and after the upside-down turning merge with each other.
摘要:
The present invention provides a cutting method for hard, brittle materials that is capable of completely cutting through hard, brittle materials such as ceramic, glass, concrete, stone and single crystal materials without the occurrence of edge chipping and at high speed. The present invention is characterized by being a method for completely cutting through a hard, brittle material 1 using a disk-shaped rotary grindstone 2, wherein the cross-sectional shape of the outer peripheral edge 20 of rotary grindstone 2 has a V-shaped pointed shape.
