Proposed is a tool with a tool insert ( ) for machining workpieces, comprising a collet ( ), designed for manual interchange of tools and for securing in position the tool insert ( ) in a tool spindle ( ), comprising at least one channel, penetrating essentially in the axial direction of the tool ( ), in particular the collet ( ), for mediums, in the particular for coolants and/or flushing agents and/or lubricants. The tool is characterized in that a second channel ( &prime;), which is separated from a first channel ( ) and which runs essentially in the axial direction, is provided for mediums, in particular for coolants and/or flushing agents and/or lubricants in the collet ( ), and that different mediums can be conveyed in the channels ( ) and ( &prime;); and that they empty into a mixing device ( ).

Tool

Material-removing precision machining tool

A polygon shaped cutting tip for a metal workpiece boring tool, the cutting tip having linear side edges lying in a common plane and adjacent side edges which pass tangentially into rounded corner regions. Parts of the corner regions and of the side edges serve as the primary and secondary cutting edges of the tip. A chip breaker edge is arranged at a distance in from the side edges. A chip breaker surface extends from the side edge to the chip breaker edge. The chip breaker edge includes linear sections corresponding to the linear side edges of the tip and has curved sections which correspond to the curved regions of the side edges. The arc of curvature of both the curved regions and the curved sections is the same although the arcuate length of the curved sections is greater. The chip breaker surface extends from the side edges of the corner regions inward toward and downward into the tip at an acute angle where it intersects the chip breaker edges.

Cutting tip developed as a polygon with a chip breaker

A boring tool for the fine finishing of surfaces of holes having at least one cutting bit and at least one guide ledge which are introduced and fixed in place in grooves arranged in the circumferential surface of the base body of the boring tool, characterized by the fact that a setting device is provided which is positively coupled with at least two cutting bits associated with each other; that the cutting bits are arranged displaceable by means of the setting device in the base body with respect to the circumferential surface; that the association of the cutting bits consists in that they are displaceable in opposite directions, with respect to the axis of rotation or center line of the boring tool; and that the setting device in each case displaces one cutting bit into a working position and the other cutting bit into a position of rest.

Boring tool

A connecting device or coupling between two coupled tool parts including a first tool part (3) which has a driver (5) and a second tool part (7) which has a groove (9) includes a connecting place or location (1) which is characterized by the fact that it includes a device (15) which compels a well-defined angle-of-rotation position or orientation between the first tool part and the second tool part.

Device for coupling tool parts

A reamer for precision machining of holes includes a reamer body and a knife plate supported above the exterior of the body and extending along the exterior. The knife plate has a front lower radial height cutting region and a rear taller radial height cutting region joined by an inclined step so that the first front region does the major cutting and the second rearward region does the finer machining. The front cutting region has an entrance bevel. The inclined flank shapes of the cutting regions are disclosed. Reamer guide strips supported along the support have a similarly shaped bevel and step as the knife plate.

Reamer with stepped knife

A metal cutting including a tool head, a cutting plate, and a snap-locking arrangement for securing the cutting plate to the tool head and formed of a projection, extending from the cutting plate or the bottom of the cavity, which is formed in tool head for receiving the cutting plate, into a hole formed, respectively, in the bottom of the tool head cavity or in the cutting plate, and a snap-action locking element located in the hole for engaging the projection and retaining it in the hole.

Metal cutting tool

A tool for precise machining of metal includes two tool parts located one within the other and formed as an inner tool and a tool head respectively, and coupling elements which enable automatic replacement of the tool.

Drill

A reamer tip having a face and a V-shaped indentation formed in the face and having sides, which form with an imaginary plane extending parallel to the face an angle of about 9.degree.-12.degree., preferably about 10.degree..

Reamer tip

A reamer tip including a main cutting edge and a auxiliary cutting edge adjoining the first main cutting edge; and a flank provided in a region of the main and auxiliary cutting edges and including a first inclined flank region having a first back angle of about 7.degree., and a second inclined flank region directly adjoining the auxiliary cutting edge, extending from the auxiliary cutting edge to the first flank region, and having a second back angle substantially smaller than the first back angle.

A cutting plate for a reamer for fine machining of metal workpieces including a main cutting edge, an auxiliary cutting edge, an apex point at which the auxiliary cutting edge is connected with the main cutting edge, and a chip deflecting surface limited by a chip deflecting step having a high point located opposite a region of the apex point, a first region associated with the main cutting edge and descending, starting from the high point, away from the main cutting edge, and a second region associated with the auxiliary cutting edge and extending relative to the auxiliary cutting edge at an angle of from 0.degree. to about 10.degree..

Cutting plate for a reamer

An interface 1 between a tool carrier 5 and a clamping shaft 3 of a machine tool holding the tool carrier is proposed comprising a hollow fitting pivot 7 which is provided at the tool carrier and is provided with a first clamping surface 19 on its inner wall, comprising a recess 9 provided at the front wall 73 of the clamping shaft for receiving the fitting pivot, a clamping member 37 is arranged in this recess 9 and is axially displaceable inside the clamping pivot, the clamping member 37 is provided on its outer side with a second clamping surface 71 cooperating with the first clamping surface via clamping elements 69 which are arranged on the outside of the clamping member, can be swiveled out radially by the clamping member against a resilient restoring force, and can be made to engage with the first and second clamping surfaces, characterized in that the clamping elements 69 are arranged at the circumference of the clamping member constructed as clamping pin 37 so as to be freely movable in the axial direction and are pressed between the second clamping surface of the clamping pin and the first clamping surface in the fitting pivot during a displacement of the clamping member in the clamping direction, so that the two parts 3; 5 assigned to the interface 1 are securely clamped together.

Cutting area

A reamer includes a cutting tip mounted in the circumferential wall of the base body of the cutting head of the reamer, and at least one guide bead located in a groove formed in the base body and extending in the longitudinal direction of the base body. The guide bead has a contact surface containing at least regionwise a diamond material.

Reamer

A cutting tool for expanding or opening up the diameter of boreholes includes at least one reversible knife plate with a front surface. The knife plate can be clamped with at least one clamping shoe into a recess provided in a cutter head. The front surface of the knife plate has at least two grooves which extend essentially parallel and preferably symmetrical with respect to the longitudinal axis of the knife plate. The grooves cooperate with projections provided on the contact surface of the clamping shoe facing the front surface of the knife plate and form a positively locked connection therewith.
