摘要： An apparatus for treating the inner surface of a vacuum chamber includes a support, means for anchoring the vacuum chamber to the support and holding the vacuum chamber, a broach having a plurality of cutting edges having cutouts, and broach drive means to which the broach arranged on the support is fitted. The broach drive means unidirectionally moves the broach relatively to the vacuum chamber in an axial direction to cut off a contaminated layer on an inner surface of the vacuum chamber. The outer diameter of each cutting edge, excluding the cutouts, is set greater than that of an immediately preceding one in a direction of a rearmost edge face from a front edge face. The apparatus may also include means for supplying an inert gas or a mixture of nitrogen and inert gases to a surface of the vacuum chamber being treated by the broach, or means for supplying a lower alcohol for dissolving contaminants contained in the contaminated layer to the surface of the vacuum chamber being treated by the broach.

摘要： There is disclosed an apparatus for forming curved and rectangular bodied needle blanks from a length of needle stock which includes a generally cylindrical inner mandrel having a plurality of longitudinal channels formed in an outer surface thereof, the mandrel being dimensioned and configured for insertion within the length of needle stock. The apparatus also includes a plurality of broaches insertable into the longitudinal channels such that an edge of each broach projects radially outwardly of the mandrel to form a plurality of inner grooves on an inner surface of the length of needle stock. There is also provided structure for forming outer grooves in an outer surface of the length of the needle stock to form a substantially grooved length of needle stock, cutters for cutting the grooved length of needle stock to form rings of curved rectangular bodied needle blanks interconnected by web portions and structure for dividing the rings at the web portions to form a plurality of curved rectangular bodied needle blanks. There is also disclosed a method of forming needle blanks from a length of needle stock having a longitudinal cavity therethrough and defining a longitudinal axis by forming at least two inner grooves in an inner surface of the length of needle stock and substantially parallel to the longitudinal axis, forming a number of outer grooves, equal to the number of inner grooves, in an outer surface of the length of needle stock and in substantial radial alignment with the at least two inner grooves to form a grooved length of needle stock and sectioning the grooved length of needle stock to form individual needle blanks.

摘要： A method for forming a longitudinally extending keyway portion in a mill roll having a central bore, in which the keyway portion may be either a keyway or a tab portion. A cutting head is provided, and includes a body and one or more cutting tools extending from the periphery of the cutting head body. The cutting head is driven through the central bore of the mill roll, and the cutting tools form one or more keyway portions adjacent and communicating with the central bore.

摘要： A tool holder has a shank which is mounted in a nonrotatable support which is longitudinally movable toward and from the work. The opposite end of the tool holder has a spindle mounted therein for rotation and provided with a central aperture in which the shank of a broach is secured. The axis of the broach is offset one degree from the axis of the holder which produces a wobble effect to the corners of the broach seriatim to produce rapid cutting of a hole to a predetermined shape. Such shape is of polygonal regular or irregular form developed by the broach. The work piece is rotated and the broach is advanced into engagement with the end face thereof and continually advanced until the broaching operation is completed.
