摘要:
The invention relates to a grinding machine that is configured as a multi-station grinding machine having two complete grinding stations. Said grinding stations have grinding heads that can be moved relative to the saw blade by means of corresponding positioning devices such as cross table arrays and/or swing tables. Positioning devices and locking devices for the work pieces also form part of the grinding stations. The work piece holder only serves to position the saw blades in so far as their center axis is to be fixed in the grinding stations. Rotation about said central axis (M) and clamping of the saw blades in the corresponding rotational position to execute the grinding operation is performed by the relevant units of the grinding stations. A grinding machine having the above-mentioned configuration makes it possible to very rapidly, accurately and economically process saw blades. The inventive grinding machine is particularly useful for sharpening saw blades during manufacturing.

The head of a work piece (46) is allocated to a work piece holding device (82) on which a work piece (10) can be arranged in such a way that the tips of the teeth (18) of a cutting tooth (12) that is to be machined are located in a stationary reference axis (A). A tool spindle (52) that can be fitted with disc-shaped tools (100) is arranged in such a way that it can be driven around the axis of a spindle (C). The head of the tool (46) is supported in such a way that it can be displaced by a movable carriage (34) which can slide back and forth along a lift guide (32) in a diagonal direction in relation to the reference axis (A). A feed carriage (24) can be displaced along a feed guide (22) in a diagonal direction in relation to the lift guide (32) and a drag bearing (42) defines a swiveling axis (B) parallel to the lift guide (32). The head of the work tool (46) can pivot around said swiveling axis by means of a swivel drive (60) so that it can move from a normal position to machine the surfaces of the cutting teeth (12) lying parallel to the reference axis (A) to an inclined position to machine the inclined surfaces of the cutting teeth (12). The distance (x) of the active surface (106) of the work tool (100) from the swiveling axis (B) can be measured with a measuring device (108).
摘要:
Zum Schleifen der mit Hartmetalleinsätzen (112) versehenen Zähnen (111) eines Kreissägeblattes (110) wird eine Kreissägeblattschleifmaschine mit einem Maschinenbett (1) und einer Kreissägeblattaufspannungsanordnung (7), einem Schleifkopf (3) mit Positionierungstaster und mindestens einer Schleifscheibe (9) mit einem Antriebsmotor (8) vorgeschlagen. Hierbei ist der Antriebsmotor (8) schwenkbar an einer Pinole (3) angeordnet, die zwischen zwei auf einer Drehlagerplatte angeordneten Maschinenlagerwänden (2) auf zwei kreisbogenförmig verlaufenden Zahnstangen (10) läuft, wobei in jede Maschinenlagerwand (2) je eine der Zahnstangen (10) angeordnet ist. Die Drehachse der Schleifscheibe (9) und dessen Antriebsmotors (8) verlaufen senkrecht zur Längsachse der Pinole (3). Die Maschinenlagerwände (2) sind auf einer Drehlagerplatte schwenk- oder drehbar angeordnet. Die Längsachse der Pinole (3) und die Dreh- oder Schwenkachse der Drehlagerplatte (4) sind so ausgerichtet, dass diese sich auf einer Schneidkante des jeweils in Arbeit befindenden Hartmetalleinsatzes kreuzen.
