摘要： PURPOSE:To increase a number of reuse times for a drill, by repolishing the drill once coating its surface thereafter recoating the drill, forming a coating layer in a small thickness in a side surface part while in a large thickness in a point end part of the drill, so as to regenerate the drill having performance equivalent to that of a drill unused. CONSTITUTION:A used surface coated drill, repolishing its exposed flank 2 and recoating the whole unit, promotes the improvement of drill performance. Here the drill is coated forming a coating layer in a point end part A, containing a cutting edge 1 and the flank 2, in a thickness larger than the thickness of a coating layer in a side surface part B containing a land 3 and a flute 4. The coating method may apply any of the PVD method, plasma CVD method, etc. in accordance with a material quality of the drill. In this way, the drill enables a number of times for reuse to be extended as a recoated drill.

摘要： PURPOSE:To make it possible to test a boundary damage of a throw away tip made of cemented carbide, by juxtaposing and combining an ordinary cast iron material and a cast iron material of which only the top surface part is made highly hard, and by using the material thus prepared as a material to be cut. CONSTITUTION:While JIS.FC 25 is used as an ordinary material 2, FC 25 of the same quality, of which a part from the surface to the depth of 2mm is made to be of prescribed hardness by induction hardening and tempering, is used as a hard-facing material 1. The respective widths of the ordinary material 2 and the hard-facing material 1 are adjusted by cutting or milling so that they are in a prescribed ratio (about 3:1) and the total thereof is 60mm. A material 6 obtained in this way is fixed by a machine vise 5, 5' and cut by a cutter having a plurality of edges 4. By this method, a boundary damage of a throw away tip made of cemented carbide can be tested.

摘要： PURPOSE:To enable complete removal of grease of a binder and to improve the life of furnace members by mounting molded bodies comprising complete powder of hard metal or the like on a multistage high-density carbon plates before sintering and slowly heating the molded bodies to change the binder in the molded body into a liquid and discharge it to outside. CONSTITUTION:Molded bodies 3 comprising complete powder of hard metal or ceramics containing a binder are mounted on multistage high-density carbon plates 2 in a carbon case 1 in a vacuum, pressurized tank 4. The bodies 3 are slowly heated to change the binder into a liquid state which is then discharged from the tank 4. The carbon plate 2 consists of high-density carbon of about 1. 5-2.1g/cm or graphite material. It is preferable to provide plural sloped grooves 10 running to a hole 9 in the center part of the plate. The binder is paraffin, and preferably degreased and removed by slowly heating at about 1-100 deg.C/h rate.
