摘要： The combination tool comprises a base body (16) with several reaming blades (18), with a chamfer (20) and a guide piece (22), arranged around the circumference of the base body, for reaming a cylinder bore and with at least one plunge blade (26), arranged axially offset from the reaming blades (18) and which may be extended radially relative to the base body (16). According to the invention, the combination tool is provided with two guide strips (30), arranged in the base body, at an angle to each other, between two reaming blades (18) which are adjacent in the circumferential direction and displaced axially relative to the above in the direction of the plunge blade (26).

摘要： The invention relates to a tool holder which can be used in machine tools and comprises a base body which can rotate around a rotational axis. The tool holder also comprises cutter holders that hold a cutting plate respectively and can be radially adjusted by means of an axially displaceable control rod and coupling means. The aim of the invention is to improve said tool holder in such a way that a puncture can be produced within a very short time. Said puncture meets high demands on the surface structure and the geometrical roundness. The tool holder is provided with at least two cutter holders that can be radially adjusted between a retracted and an extended position. The cutters of the cutter holders can be simultaneously engaged with the workpiece for producing a puncture.

摘要： A kit is disclosed for cutting differing sized pipes internally. The kit includes a pipe cutting apparatus, and a plurality of assemblies. The pipe cutting apparatus includes at least one drive member. The plurality of assemblies, attachable to the pipe cutting apparatus, each include: (1) at least one feed member to extend at least one cutting member against a pipe internally and to retract the at least one cutting member from the pipe internally, the at least one drive member to rotate the at least one cutting member against the pipe internally; or (2) at least one clamping member to secure the pipe cutting apparatus to the pipe internally. Each of the plurality of assemblies differ in size so that differing sized pipes can be cut internally by the pipe cutting apparatus by attaching the appropriately sized assembly to the pipe cutting apparatus.

摘要： The invention relates to a tool head with a housing (11) in which at least one thrust wedge (31, 32, 33) movable in a first toothed guide in a longitudinal direction (L) has been provided, in each case associated, in the housing (11), with a support (21, 22, 23) movable in a second toothed guide in a transverse direction (R1, R2, R3) arranged perpendicularly with respect to the longitudinal direction (L), and the thrust wedge (31, 32, 33) and the support (21, 22, 23) are in sliding contact with one another by way of an oblique contact surface (51, 52, 53) and a movement of the thrust wedge (31, 32, 33) in a longitudinal direction (L) by way of the oblique contact surface (51, 52, 53) brings about a transverse movement of the associated support (21, 22, 23) and a cutting tool (161, 162, 163) can be fastened to the support (21, 22, 23) and the support (21, 22, 23) has a support arm (101, 102, 103) running in transverse direction (R1, R2, R3).

摘要： An improved tool assembly for enhancing the surface of a heat transfer tube is provided. The tool assembly includes rods having cutting tips and positioned in rod guides which are slidably positioned in shafts provided in a tool holder. In an equilibrium state, the cutting tips do not extend from the tool holder. When a force is applied to the rod guides, the rod guides move in a first direction along the shafts in the tool holder, resulting in exposure of the cutting tips which enhance the tube surface. When the force is removed from the rod guides, the rod guides move along the shafts in a direction opposite the first direction to retract the cutting tips within the tool holder. In this way, the cutting tips are protected when not in use.
