Ein Fräswerkzeug weist einen Werkzeugkopf (2) und einen austauschbaren Schneidenträger (3) auf. Der Werkzeugkopf (2) ist an eine Werkzeugaufnahme (4) ankoppelbar und der Schneidenträger (3) weist eine Mehrzahl um seinen Umfang verteilt angeordnete Schneiden mit jeweils einer vorderseitigen Planschneide (311) und einer winklig dazu verlaufenden Umfangs schneide (312) auf. Dabei weist der Schneidenträger (3), einschliesslich der Schneiden, bei einem Durchmesser von minimal fünfzig mm eine Dicke von maximal zehn mm, insbesondere von maximal sechs mm auf.
摘要:
Disclosed is an improved method (26) for cryogenically cooling machining tools (20) where a feedback-controlled system (10) uses temperature, pressure, flow and/or infrared sensors (16) to regulate flow of a cryogenic coolant and functioning of a cutting tool (20).
摘要:
The invention relates to a lathe tool (10) for machining workpieces, said tool comprising a base body (12) having a clamping section (14) and a tool head (16) which comprises a cutting region (18) having at least one cutting edge (20), wherein the tool head (16) comprises at least one coolant channel (22) for supplying a cooling and/or lubricating fluid into the cutting region (18). According to the invention, at least some sections of the coolant channel (22) have a cross-section (24) that tapers in the direction of the tool head (16), and in this region, at least two coolant outlet lines (30, 38) that branch off from contact points (40, 42) of the coolant channel (22) in the direction of the tool head upper surface (44) are arranged in the region of the tool head (16), wherein the at least two coolant outlet lines (30, 38) are arranged at positions (40) that are offset in the axial longitudinal direction of the coolant channel (22). The invention also relates to a production method for a claimed lathe (10), in which method the blank of the lathe (10) is produced by means of a sintering method in which the coolant channel (22) of the lathe (10) is formed integrally in the sintering method at the same time.
摘要:
[Object] To provide a cutting tool holder that allows a coolant to be supplied from a lateral flank side of a cutting tip toward a cutting edge, without providing a protruding portion at a lateral flank side of the cutting tool holder as in the conventional art. [Solution] A recess surface portion 123 is formed in a predetermined range L1 from a front end 103 toward a rear end, of a lateral flank 120 of a front end portion 102 of a holder 100, so as to be recessed relative to a lateral flank 120b of a rear portion 122, a circular arc surface portion (frontward-facing surface) 125 formed in a circular arc shape as seen from a rake face 105 side is provided on the rear of the recess surface portion 123, and an ejection port 150 is opened in the frontward-facing surface. Accordingly, supply of the coolant at the lateral flank side is ensured, and cutting can be performed at a position closer to a chuck Ck due to no protruding portion being present at the lateral flank side of the holder as in the conventional art.
摘要:
The invention relates to a tool for machining a workpiece. The tool has a first tool component (12) which has a first internal coolant bore (16a, 16b) and a first connection interface (22) at a first end face. The first connection interface (22) has a first end surface (28) for applying a joining material and an elevation (30) which protrudes from the first end surface (28). A first coolant outlet (10a, 20b) of the first internal coolant bore (16a, 16b) is arranged on the elevation (30). The tool additionally has a second tool component (14) which has a second internal coolant bore (18a, 18b) and a second connection interface (26) at a second end face. The second connection interface (26) has a second end surface (34) for applying the joining material and a depression (36) which is introduced into the second end surface (34). A second coolant outlet (24a, 24b) of the second internal coolant bore (18a, 18b) is arranged in the depression (36). The first tool component (12) and the second tool component (14) are connected to each other by means of the joining material applied onto the first and second end surface (28, 34) such that the first coolant outlet (20a, 20b) is aligned with the second coolant outlet (24a, 24b).
