摘要： PURPOSE: To reduce the susceptibility of a permanent magnet to rust, by forming a specific α-Fe2 O3 coating film on the surface of a surface-treated NdFeB-based magnet by heat-treating the magnet. CONSTITUTION: When an α-Fe2 O3 coating film having a thickness of 0.5-5μm, preferably, 1-3μm is formed on the surface of an NdFeB-based permanent magnet containing 28-35wt.% Nd. 0.9-1.2wt.% B, and Fe, with the Nd being able to be substituted partially with another SE metal, the susceptibility of the permanent magnet or rust can be reduced. In addition, the surface of the magnet can be passivated by heat-treating the treated magnet at a temperature from 600 deg.C to the sintering temperature in an oxidizing atmosphere.

摘要： PURPOSE: To simplify handling in exchanging a tool by closing a tool adapter by tongue-shaped parts having spring resiliency so that a collet chuck may be put on a head of a chick rod when the tool adapter is inserted into a spindle. CONSTITUTION: When a tool adapter 16 is assembled in a tapered receiving hole of a spindle, a conveying head 27 is inserted, locked by the cooperation of a sleeve 29, a chuck rod 20, a spring 21 and a ball 30, and inserted into the spindle in this state. When the chuck rod 20 is pressed to an extruding pin of a pull-rod, the conveying head 27 is separated, the adapter 16 is held by a plurality of tongue-shaped parts 22 to be advanced to the rear part of the chuck and having spring resiliency. When the spindle is rotated at 45 deg., a lock bar 25 is outwardly pressed through an eccentric cam 26 of the conveying head 27, inserted into a hole 39 of an operating body 38, and housed in a tool magazine after the conveying head 27 is detached. Therefore, handling in exchanging a tool can be simply performed.

摘要： PURPOSE: To prevent a compressed air supplying part from corroding by arranging a check valve in the compressed air supplying part, in a tool system in which a tool head part is exchangeably arranged by a clamping device, and a refrigerant supplying part is incorporated. CONSTITUTION: A tool holder 1 or a tool holder head part 2 is provided with a compressed air supplying part 12 parallel to a refrigerant supplying part 8. In the contact range of the tool head part 11 and the tool holder head part 2, the compressed air supplying part 12 is uniformly distributed and guided from an annular passage 13 to the end surface of the tool holder head part 2. A check valve 15 is arranged in the compressed air supplying part 12, and a ball 16 is pressed to a valve seat 18 by a spring 17. When the compassed air supplying part 12 is compressed by compressed air, the ball 16 is lifted from the valve seat 18. As a result, compressed air passes the check valve 15 and is allowed to flow out of the front end surface of the tool holder head part. Since the check valve 15 stops inflow of refrigerant to the compressed air supplying part 12, corrosion of the supplying part 12 can be prevented.

摘要： PURPOSE: To reduce load to a bearing of a tool turret to facilitate operation by loading counter force in the opposite direction of a chuck-releasing force onto cutting tool base holder or its cutting tool shank during chuck release operation. CONSTITUTION: A piston 25 in a cylinder 22 is slidingly guided against pressure of a spring 28, the cylinder 22 is axially connected with a holding claw 4 through an intermediate connecting member 23, and a piston 25 is directly connected with a crimp ram 5. A conduit 32 is linked with a cylinder chamber 34, the piston 25 is moved by a pressure medium in the cutting tool head direction against its pressure, the cylinder 22 is moved on the opposite direction of the piston 25 against a force of a conical spring 26 by the pressure applied to a surface 37, and a ring surface 44 and a stopper surface 10 abut each other to hold a cutting tool shank 8.

摘要： PURPOSE: To quickly replace a tool by providing a spiral guide for a pressing and separating member on a rotatable clamping shaft having the other spiral guide for a clamping member, and obtaining maximum clamping force and pressing and separating force by the short movement of the clamping member. CONSTITUTION: When a clamping shaft 17 is rotated, a clamping ball 20 is moved from a stationary position on a clamping passage 18, acts on the inclined side surface 26 of a hole 25 of a tool head 11, and pulls the tool head 11 into a receiving part 15 of a tool holder 10. Since a space is provided by a reverse spiral guide 19, the pressing and separating member 21 is pressed back by the surface 28 of the tool head 11, and the tool head 11 is strongly pressed into the receiving part 15 of the tool holder 10 and unmovably held. When the clamping shaft 17 is reversely rotated, the pressing and separating member 21 is moved in the direction of the tool head 11, ejects the surface 28 of the tool head 11, and pushes the tool head 11 from the tool holder 10 with strong force, and there by releasing pressing and clamping.
