30results about How to "Reduce cutting pressure" patented technology

An acetabular reamer (10′) for cutting a required cut shape. The reamer has a cutting shell (12′) having a series of doubly curved cutting teeth (16′) thereon of a quantity to substantially reduce a cutting pressure on each tooth as well as to reduce a size of a typical chip generated upon cutting. Substantially all the teeth each have a matched arc cutting edge (20′) of substantial length that has a cutting profile which substantially matches a profile of a shape to be cut. Such a configuration reduces the number of teeth required to cut the shape.

A shank cutter has plural circumferential cutting edges which run in a helical manner in the region of its cutting section and of which at least one critical number are equipped in each case with a preferably essentially flattened roughing profile with chip-separating grooves with rounded bases, so that the chip-separating grooves of cutter ridges which are adjacent in the circumferential direction are axially offset relative to each other. To create a tool which provides long service life by combined advantages of a vibration-stabilized finishing cutter and a conventional roughing cutter, at least one circumferential cutting edge has an angle of twist which differs from that of another circumferential cutting edge. In addition, the chip-separating grooves of the circumferential cutting edges which are equipped with a roughing profile in each case merge into a preferably essentially flattened central section of the roughing profile by means of a predefined flank radius.

A method for cutting optical element includes such steps as providing a bench, fixing an optical element to be cut onto the bench, cutting it to a predefined deepth, turning over the optical element, fixing it onto the bench, and cutting the residual tickness.

A method of manufacturing electronic dies by separating a wafer into electronic dies, wherein the method comprises forming a groove in the wafer with a first material removal tool having a first thickness, enlarging the groove by a second material removal tool having a second thickness larger than the first thickness, and subsequently increasing a depth of the groove by a third material removal tool having a third thickness smaller than the second thickness until the wafer is separated.

The invention relates to an electrode graphite end mill comprising a ball head (9), at least one roughing land (6, 8) and at least one finishing land (5, 7). Each roughing land (6, 8) is formed as a peripheral side file comprising a plurality of teeth (10, 11); each finishing land (5, 7) has a plurality of teeth extending helically around the tool axis Peripheral grooves, wherein the peripheral grooves space apart peripheral lands respectively having peripheral cutting edges (12, 13), machining the first set (5, 6) of the lands (5, 6, 7, 8) , 8) than the working area of ​​the second group (7) of the machining lands (5, 6, 7, 8) extends farther towards the tool head.

The invention relates to the technical field of mechanical processing, in particular to a waste recycling and crushing device for mechanical parts processing, which includes a grinding outer ring, a cutting inner ring, an elastic member, and an adjustment rod. The grinding outer ring is hinged around a vertical axis by an even number of outer ring pieces Enclosed; the cutting inner ring is located in the grinding outer ring, and is formed by hinged and enclosed by a plurality of inner ring pieces equal to the outer ring piece around the vertical axis; the elastic member includes an upper ring, a lower fixed ring, a spiral The elastic bar, the cylindrical structure enclosed by the spiral elastic bar defines the grinding cavity with the grinding outer ring, and defines the cutting cavity with the cutting inner ring; the two ends of the adjusting rod are respectively hinged at a hinge position of the outer ring piece and a hinged position of the inner ring piece; the hinged position of the cutting inner ring is changed by squeezing the waste, and then the hinged position of the grinding outer ring is changed through the adjustment rod, which increases the area of ​​the grinding chamber and reduces the grinding resistance of the grinding chamber, so that The power of the device is more distributed to the cutting chamber, which accelerates the cutting of waste in the cutting chamber.
