The invention relates to a side milling cutter (1) which comprises a disk body (11) with a central hub (12) for accommodation in a milling drive, and a plurality of cutters (21) which are arranged on the outer periphery thereof. A plurality of inner cooling lubricant channels (3) extend in the disk body (11), said channels having two or more outlet openings (31) in the area of each cutter (21). Said outlet openings (31) are oriented such that a cooling lubricant jet (K) which exits from the cooling lubricant channel (3) can be directed to the cutter (21). The invention also relates to a production method for the side milling cutter (1).

The spherical cutting tool and method of using the same are centered in the novel integration of a sphere cutter, with a roller burnisher tool, which may be adjustable, and may further be contained in a system comprising several additional components such as an indexer and a lathe, mill, or custom machine. The tool of the invention may further comprise a drill, end mill, reamer, or other similar cutting tool on one end, with the sphere cutter and roller burnisher. The method of the invention is comprised of steps for using the tool and system of the invention in a novel way, including steps for manipulating and actuating the novel spherical cutting tool to engage the inner or outer surface(s) of a workpiece, using multiple cutting operations on a fixed or movable indexer, or machining using the tool, system, and methods of the invention. The system of the invention utilizes at least two machine drive units, such as a lathes or other rotary machines, in conjunctions with an indexer, to be configured as a system for pre-drilling, drilling, reaming, and cutting. The system may be configured as a system for spherical cutting and hole finishing using the tool of the invention.

A tube-facing machine includes a driving unit including a driving shaft and a motor for rotating the driving shaft, a cutting unit including a cutting tip mounted to the front end of the driving shaft and having a blade, and a tube-mounting unit. The cutting tip is disposed such that an angle between an imaginary reference line extending outwards from the center point of the tube in a radial direction and an imaginary line extending from the center point of the tube to a point at which the blade meets the inner circumference of the tube in a rotating direction of the cutting tip is greater than an angle between the imaginary reference line and another imaginary line extending from the center point of the tube to a point at which the blade meets the outer circumference of the tube in the rotating direction of the cutting tip.

An assembled chamfer mill comprises a tool holder, an extension shaft, and chamfer bits locked to two ends of the extension shaft. The chamfer bits each have upper blades and lower blades for chamfering the edges of a workpiece simultaneously. The length of a shaft body of the extension shaft may be set in various sizes. Depending on the thickness and shape of the workpiece, the shaft body having an appropriate length is selected, so as to control the distance between the two chamfer bits. Another extension shaft may be provided to connect a further chamber bit for chamfering the edges of the workpiece simultaneously.

A cutting insert 2 comprises a peripheral side surface 30 which is parallel to a central axis O of a first end surface 10 and a second end surface 20. The peripheral side surface 30 comprises a first side surface 31 facing a first major cutting edge 11, a second side surface 32 facing a first wiper edge 12, and a third side surface 33 facing a first inner edge 13. A flank 311 of the first major cutting edge 11 and a flank 321 of the first wiper edge 12 are inclined such that the flank 311 and 321 approaches the central axis O as it heads toward the first end surface 10. The flank 311 of the first major cutting edge 11 is located on a different plane from the first side surface 31. The flank 321 of the first wiper edge 12 is located on a different plane from the second side surface 32. Meanwhile, a flank of the first inner edge 13 is located on the same plane as the third side surface 33.

A cutting insert and a shoulder milling tool are disclosed. The cutting insert includes a surface-wiping secondary cutting edge inclined in relation to a median plane of the cutting insert such that a distance to the median plane decreases in a direction toward a corner cutting edge. The corner cutting edge, as seen in a side view along the median plane and towards a main cutting edge, has a concave curve.

The present invention relates to a method for producing a fiber-plastics-composite tool component (1) having a matrix system (6) that has embedded fibers, PBO fibers (4) being selected as the fiber component and a thermosetting plastics matrix (8) being used as the matrix component of the matrix system (6) (S1), which thermosetting plastics matrix has such adhesion to the PBO fibers (4) in the hardened fiber-plastics composite (2) that the coefficient of thermal expansion of the PBO fibers (4) is imparted to the matrix system (6). The invention also relates to a load-bearing tool component (1) of a chip-removing tool in the design of a fiber-plastics-composite press-molded part, the load-bearing tool component (1) comprising a matrix system (6) that has a thermosetting matrix component (8) and comprising PBO fibers (4) embedded into said thermosetting matrix component.
