A key cutting machine is provided. The key cutting machine comprises a rotary cutter, an anvil and control circuitry. The rotary cutter is for cutting into the blade of a key blank. The anvil is for stabilising the key blank whilst the rotary cutter is cutting the key blank. The control circuitry is configured to: cause at least one of the anvil or the rotary cutter to move, such that the anvil is located substantially at a first face of the blade of the key blank and the rotary cutter is located substantially at a second face of the blade of the key blank, the second face of the blade of the key blank being on an opposite side of the blank to the first face; and cause the rotary cutter to cut into the second face of the blade of the key blank.

A milling head includes a milling head base, a plurality of blades annularly arranged around the milling head base; and an actuator to rotate the milling head base. Each of the plurality of blades extends from the base at a differential radial distance as compared to a neighboring blade from the plurality of blades.

The present invention is to eliminate formation of a shape that induces reduction of fatigue strength, without forming a step part, in a shape portion formed by machining. This processing apparatus includes end mills having bottom blades formed in a curved convex shape, and arcuately formed radial blades provided in corner areas; a drive section for driving the end mills; and a control unit for controlling the drive unit. The control unit includes a planar-shape-formation unit that controls the drive unit so as to form, in a workpiece, only a planar-shape portion adjacent to a fillet shape portion in such a manner that a portion of the shape to be processed corresponding to the fillet shape portion is left unprocessed; and a fillet formation unit that controls the drive unit so as to form the fillet shape portion in the workpiece in a single pass using the radial blades.

A method of manufacturing a metallic rotor of an eccentric screw pump, comprising clamping a workpiece extending along a central longitudinal axis in a workpiece clamping device and removing material from the workpiece by cutting with a cutting tool. The invention further comprises not producing the surface of the rotor in a three-axis whirling process, using the cutting tool to produce the outer surface geometry of the rotor, advancing the cutting tool along an axis of advance that is parallel to the longitudinal axis of the rotor, and rotating the cutting tool about an axis of tool rotation that is parallel to the longitudinal axis of the rotor.

A method for manufacturing a hitting panel with precise dimensions and high quality for golf club head is disclosed to include the steps of material preparing and cutting, primary hot pressing, planar milling, secondary hot pressing, third hot pressing, cold pressing and hitting surface formation.

An example end mill includes a shaft, a cutting head positioned on one end of the shaft, and an edge relief cutting head positioned on the shaft spaced apart from the cutting head. The portion of the shaft between the cutting head and the edge relief cutting head has a diameter that is less than the diameters of the cutting head and the edge relief cutting head. The end mill is rotated around a longitudinal axis of the end mill and revolved around a central axis of a hole to be cut, with the longitudinal axis radially offset from the central axis, to cut the hole with the cutting head and cut an edge relief in a leading edge of the hole with the edge relief cutting head.

A system for forming a radiating cable includes radiating machine tool having a cable receiving channel and a carriage. The carriage includes an aperture configured to align with the cable receiving channel, and a milling motor having a milling cutter. A radiating machine tool also includes a carriage receiving structure. A radiating machine is in communication with one or more controllers that receives a feeding speed associated with feeding a coaxial cable into the cable receiving channel, receives a pattern, determines a speed of rotation of the carriage by analyzing the feeding speed and the pattern, causes the carriage to rotate about the axis at the determined speed, and causes the milling cutter to perform one or more cutting actions to create one or more slots forming at least a portion of the pattern in an outer conductor of the coaxial cable.

A first lateral surface of a cutting insert includes a first region, a second region, and a third region. The first region includes a first upper region inclined outward, and a first lower region that is parallel to a central axis. The second region includes a second upper region inclined inward, and a second lower region that is parallel to the central axis. The third region includes a third upper region inclined outward, a third lower region, and a concave part. The third lower region is located more outside than the third upper region and is parallel to the central axis. The concave part is located between the third upper region and the third lower region.
