Tool system
Tool system (1) comprising a tool holder (2) that includes an insert seat (17) for accommodating an insert (6) having a depression (7), further comprising a clamping element (4) that has an opening (26) for accommodating a clamping means (15), and a projection (5), and comprising a mechanism (functional dimension (Fx) that limits the linear mobility of the clamping element (4). This ensures that a disposable insert (6) can be repeatedly securely clamped.
NOZZLE FOR PROVIDING COOLANT FLUID TO A CUTTING EDGE OF A METAL CUTTING TOOL AND A METAL CUTTING TOOL
A nozzle is arranged to provide coolant fluid to a cutting edge of a metal cutting tool. The nozzle includes at least one internal inlet coolant channel and at least one internal outlet coolant channel. The internal inlet coolant channel is connected to a coolant inlet and the at internal outlet coolant channel is connected to a coolant outlet for directing the coolant fluid to the cutting edge. The nozzle further includes a plenum chamber having at least one inlet opening connecting the internal inlet coolant channel and the plenum chamber and at least one outlet opening connecting the internal outlet channel and the plenum chamber. Each of the inlet openings have a cross-sectional area A1.sub.i and each of the outlet openings have a cross-sectional area A2.sub.i, wherein—Σ.sub.i=1.sup.nA1.sub.i>Σ.sub.i=1.sup.mA2.sub.i, where i is an integer, n is the number of inlet openings, and m is the number of outlet openings.
Metal cutting tool and cutting plate provided in the shape of a donut
A metal cutting tool has a supporting tool, which has a recess for accommodating a cutting plate. The cutting plate is provided with a clamping trough, which is held in the supporting tool by a clamping claw. The clamping claw is fixed against the supporting tool by a clamping screw. A pressure piece is placed on the clamping claw and its underside facing the cutting plate is provided with a cam, which is in contact with the clamping trough and the clamping claw pulls the pressure piece toward the clamping screw.
Cutting insert having lower anti-slip recess, insert holder and cutting tool
A cutting insert includes an insert peripheral surface that includes at least one planar major insert side abutment surface and an insert lower surface that includes an anti-slip recess recessed therein. The anti-slip recess includes at least one elongated and straight anti-slip groove. Each major insert side abutment surface is oriented parallel to a groove longitudinal axis of a respective anti-slip groove. An insert holder includes a holder pocket. The holder pocket includes a pocket peripheral surface which includes planar major pocket side abutment surface and a pocket base surface having an elongated and straight anti-slip rib. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the anti-slip rib is located in the anti-slip groove that is oriented parallel to the major insert side abutment surface that abuts the major pocket side abutment surface.
Miniaturized cutting plate
The invention relates to a cutting plate for a chip-removing cutting tool, comprising a cutting plate top face and a cutting plate bottom face, one or more lateral faces, cutting edges at the transition between the cutting plate top face and the one or more lateral face, and a circular chip recess in the cutting plate top face that has an outside diameter d1. In order to reduce the production costs, according to the invention the following applies to the outside diameter d1 of the chip recess: 2 mm<d1<=6 mm, preferably 2 mm<d1<5 mm.
TURNING TOOL CUTTING INSERT AND TURNING TOOL
A turning tool cutting insert having an insert face with a rake face includes a primary land extending along a first cutting edge. The primary land includes a first primary land portion adjacent a linear edge portion, and a second primary land portion adjacent a central portion of the corner edge portion. The first primary land portion differs from the second primary land portion. A transitional primary land portion adjoins the first primary land portion and the second primary land portion, and forms a transition between the first primary land portion and the second primary land portion. The transitional primary land portion is arranged only adjacent an outer portion of the corner edge portion. Further, a turning tool including a turning tool cutting insert is disclosed.
GROOVING TOOL WITH BRAZED CARBIDE TOP CLAMP
A tool is provided having a tool holder and a brazed top clamp positioned in a portion of the tool holder. The brazed top clamp is made of a material that has a hardness that is greater than the material that makes up the tool holder. In certain embodiments, the tool holder has a slot that is in the shape of a “T-slot” and the top clamp is in the shape of a “T shaped rail” that is positioned within the “T-slot” of the tool holder.
CUTTING INSERT HAVING LOWER ANTI-SLIP RECESS, INSERT HOLDER AND CUTTING TOOL
A cutting insert includes an insert peripheral surface that includes at least one planar major insert side abutment surface and an insert lower surface that includes an anti-slip recess recessed therein. The anti-slip recess includes at least one elongated and straight anti-slip groove. Each major insert side abutment surface is oriented parallel to a groove longitudinal axis of a respective anti-slip groove. An insert holder includes a holder pocket. The holder pocket includes a pocket peripheral surface which includes planar major pocket side abutment surface and a pocket base surface having an elongated and straight anti-slip rib. When the cutting insert is releasably attached to the insert holder, to constitute a fastened position of a cutting tool, the anti-slip rib is located in the anti-slip groove that is oriented parallel to the major insert side abutment surface that abuts the major pocket side abutment surface.
Cutting tool comprising a cutting element releasably attached to a support member by means of a clamping jaw
The invention relates to a cutting tool, in particular a rotating machining tool, comprising a support member, a cutting element that is releasably clamped to the support member, and a clamping jaw which is located on the support member, can be secured by means of a clamping screw and clamps the cutting element against the support member. According to the invention, a lifting element is provided between the support member and the clamping claw; when the clamping screw is unscrewed, said lifting element lifts the clamping jaw off the cutting element located on the support member.
Carrier tool, cutting insert, and clamping element
The invention relates to a carrier tool (1) comprising a clamping element (2) with a clamping element projection (3) and comprising a cutting insert (4) with a clamping recess (5) on the cutting insert surface (13) for machining workpieces. The clamping recess (5) has an annular indentation (9) with a recess base (7), and the indentation (9) transitions from the recess base (7) into the cutting insert surface (13) via an annular surface (8). The indentation (9) surrounds an elevation (10), the tip (11) of which lies above the recess base (7) and below the cutting insert surface (13). The clamping element projection (3) engages into the clamping recess (5) and thus clamps same on the carrier tool (1). In order to allow a pre-centering of the contour of the clamping element projection (3) and the contour of the clamping recess (5) when closing the clamping element (2), the contours of the clamping element projection and the clamping recess thus engaging into each other in a form-fitting and precisely positioned manner, the clamping element projection (3) has an annular contour (12) which surrounds the elevation (10) in the clamped state but does not contact the elevation and rests solely on the annular surface (8).
