The method consists in that a flat work in an initial position is oriented horizontally between cooled mold beams. Plasma torches are arranged in line across the parallel side edges so that the anode spots of the extreme torches are confined by said edges of the work. By supplying a plasma forming gas and electric current to the plasma torches the work is heated with the formation of a metal pool which extends across the work from edge to edge. By relatively moving the work and the plasma torches in a horizontal plane and along the edges of the work movement of the metal pool over the surface thereof is effected and thereby a remelted layer as thick as the pool is deep, is obtained. The apparatus for carrying out the method comprises a sealed chamber containing a mold having two beams arranged in a horizontal plane and being parallel to one another. Installed in the chamber are plasma torches mounted on shafts and connected through supply lines with the sources of plasma forming gas, electric current and cooling water. Each of the shafts is journalled in a sealing bush installed in the wall of the sealed chamber so that the axis of the shaft is parallel to the beams. Each shaft is rotatively driven by a drive. The apparatus further comprises a drive for relatively moving the work and the shafts in the plane parallel to the beams, connected with at least one of the elements taking part in such movement. The practice of the method with the help of the apparatus of the invention permits a high-quality work of a predetermined macrostructure of a surface layer, to be produced at a higher rate of treatment.

An apparatus for abrasive machining of workpieces comprises a base in the form of a carriage, a tool head having a spindle with an abrasive tool fastened thereto, an articulated four-bar linkage, a drive for rotating the abrasive tool and an actuating cylinder for urging the abrasive tool to a workpiece, the actuating cylinder being pivotally mounted on the base and a movable link thereof being pivotally connected to one link of the articulated four-bar linkage. The spindle of the tool head is arranged in a plane of the articulated four-bar linkage and connected to the drive for rotating the abrasive tool through a telescoping cardan shaft to thereby considerably reduce the bulk of the tool head movable parts and improve the tracing of the tool over the surface of the workpiece being machined.

A mold comprises a base, a split die and a plunger. The base has longitudinal shoulders with resilient elements, and sloping surfaces which form an upwardly flaring nest adapted to accommodate a vertically movable die. The side walls of the die have their sloping surfaces in contact with the sloping surfaces of the longitudinal shoulders and, together with the die end walls, are placed around the die bottom. Provided between the base and the die are means for lifting the latter and means for supporting the die bottom in the raised position after the die has been lowered. Such die construction makes it possible to reduce the time required for its assembly and disassembly, as well as for detaching the finished abrasive segment from the die walls.

A method of machining outer surface of bodies of revolution by way of cutting, wherein a blank and a cutting tool are rotated about their axes, arranged out of line in mutually perpendicular planes, and are moved relative to each other at the beginning of a pass in the direction perpendicular to the blank surface being machined for cutting-in through the cutting depth, while the length of the cutting edge of the cutting tool is selected such that it spans the width of the blank cutting surface and, in the course of the cutting tool rotation, successively passes the blank cutting surface over the entire length thereof. The cutting machine for accomplishing the above process, has bed stocks which are mounted for positioning and rotating the blank being machined, and a rest arranged in guides provided in the bed. The rest is designed to carry a cutting tool with end cutters mounted on the rest for rotation about an axis arranged out of line with the centerline of the stocks in a plane perpendicular to the plane passing through the centerline of the stocks. The rest is mounted in the guides provided in the bed parallel with the rotation axis of the cutting tool whose end has a diameter somewhat greater than the distance between the stock centers in the course of cutting, while the cutters are arranged essentially radially at the end face and have a cutting edge length somewhat smaller than the length of the end face radius.
