A mold casting process comprises, after pouring of a molten metal into a mold, rapidly cooling that surface layer of a cast product which is in contact with a mold, and releasing the resulting product from the mold when the surface layer thereof has been converted into a shell-like solidified layer. Such process is used for casting a mechanical part blank and apparatus for carrying out the process is provided.

A workpiece gear to be finished is held in mesh with a gear finishing tool with substantially no backlash therebetween. The gear finishing tool is then driven in mesh with the workpiece gear, and the workpiece gear is rotated in synchronism with the driven movement of the gear finishing tool. Simultaneously, the gear finishing tool and the workpiece gear are moved reciprocally with respect to each other in the direction of a tooth trace for finishing gear surfaces of the workpiece gear. With this gear finishing method, gears can be finished highly accurately with no profile error and at an increased rate. An apparatus for carrying out the gear finishing method is of a simple construction.

A milling cutter has a cutter body including one or more steps extending along the outer peripheral edge of the cutter body. Cartridges are detachably mounted on the step, each of the cartridges having a plurality of equally spaced cutting edges. Preferably, the cutter body has a radially outer step and a radially inner step close thereto, and the cartridges with roughly cutting edges are mounted on the radially outer step. Roughly cutting edges and finishing cutting edges may be attached to the outer and inner surfaces of a single cartridge. When the cartridges are mounted on the step, the cutting edges are equally spaced fully around the cutter body for successive milling operation on a workpiece.

A method and apparatus for forge-shaping sheet-shaped members having upper and lower dies for pressing and forge-shaping a sheet-shaped material heated to a quenching temperature or an imperfectly quenching temperature set from a required hardness. The apparatus also includes cooling ducts for quenching the forge-shape material. The material is continuously quenched as it is kept pressed.

A brake disk and process for producing the same which is particularly suitable for use on motorcycles. A stainless steel material of particular chromium content is subjected to a heat-treating and press-quenching step to form a brake disk having a sufficient hardness required for the function of a brake and being of favorable appearance for use on motorcycles.

An apparatus and method for forming an integrally-shaped brake disk for a vehicle. The method comprises heating the brake disk material, and maintaining the material heated while it is inserted between upper and lower dies of the apparatus. The central and outer peripheral portions of the material are pressed and held. The intermediate portion between the central and outer peripheral portions is drawn and shaped by relative motion between the dies. The material is continuously quenched while it is maintained pressed and held.
