A cutting tool cover set to a cutting tool which includes a hollow shaft body and at least one insert attached to an end face of the shaft body and cuts by bringing the insert into contact with a work while rotating the shaft body. The cutting tool cover includes: a body portion fixed to a top end portion of the shaft body; and an extension portion extended outward from the circumferential edge of the body portion in the entire circumference of the top end portion of the body portion to cover the surface of the work.

A blast processing device includes a first nozzle, a second nozzle, and a moving mechanism. The first nozzle blasts a blasting material toward a workpiece, using first compressed air. The second nozzle blasts second compressed air for adjusting a diffusion range of the blasting material. The moving mechanism moves the first nozzle and the second nozzle over the workpiece.

Blast processing device and blast processing method

According to one implementation, a blast treatment device includes at least one nozzle, a movement structure and at least one weight member. The at least one nozzle injects blast media. The movement structure reciprocates the at least one nozzle along a track. The at least one weight member cancels a vibration caused by reciprocating the at least one nozzle. Further, according to one implementation, a blast treatment method includes injecting blast media from at least one nozzle; manufacturing a blast treated product by reciprocating the at least one nozzle along a track; and canceling a vibration, caused by reciprocating the at least one nozzle, by at least one weight member.

An attachment for dust collection for cutting machining includes a rotation mechanism and a dust collection enclosure for enclosing at least part of a tool. The dust collection enclosure is rotatably configured by being fixed to the rotation mechanism. A gap for checking a machining state is provided in the dust collection enclosure.

A milling insert includes a polygonal tubular insert body which has: rake faces on one polygonal surface thereof, flanks composed of circumferential surfaces adjacent to the polygonal surface, and cutting edges defining a ridge line where the rake faces and flanks intersect each other as cutting edges. The rake faces have serrations where mount portions and valley portions are arrayed alternately to intersect the cutting edges. The ridge line has a waveform shape when the flanks are viewed from above. Bottom portions and top portions of the waveform are formed into concave circular arc portions and convex circular arc portions, respectively, and are alternately repeated. Both of the concave and convex circular arc portions are a &#xbc; circular arc or more to a &#x2153; circular arc or less. Each of the concave circular arc portions is unevenly located between the convex circular arc portions adjacent thereto.

There is provided a separation distance derivation system and a thickness gauge. The separation distance derivation system has a thickness gauge that includes: a plurality of blades having first ends inserted between objects; and RFID tags respectively fixed to part of the blades and storing readably thickness information corresponding to the thickness of the respective blades. The separation distance derivation system has also a reading device that includes an RF receiver for establishing contact-less communication with the RFID tags and reading the thickness information, and a controller for summating the thicknesses of the blades, as denoted by the read thickness information, to derive thereby a separation distance.
