Abstract

The present invention relates to a method for grinding of a workpiece with a grinding tool, wherein an axis of rotation of the grinding tool is oriented perpendicular to a feed plane of the grinding tool, comprising the following steps: a) Movement of the grinding tool at a first velocity into a machining region of the workpiece, b) Establishment of contact between the grinding tool and a first entry region of the workpiece at a second velocity, c) First traverse of the grinding tool at the second velocity through the workpiece along a predefined contour located in the feed plane, d) First extraction of the grinding tool at the second velocity from a first exit region of the workpiece, e) Establishment of contact between the grinding tool and a second entry region of the workpiece at a third velocity, f) Second traverse of the grinding tool at the third velocity through the workpiece along a horizontal traverse direction located in the feed plane, g) Second extraction of the grinding tool at the third velocity from a second exit region of the workpiece.

Abstract

A device and method for grinding and/or milling teeth of saw bands where a feed device for the clocked feeding of a temporary workpiece is formed from a plurality of mutually parallel saw bands includes a clamping unit into which the temporary workpiece is clamped, and a machining unit with at least one machining tool for simultaneous machining of a plurality of teeth of the temporary workpiece is individually modifiable and with which these types of teeth of saw bands can be efficiently and economically manufactured. The clamping unit is displaceable together with the feed device along a feed direction.

Abstract

A machine for the milling or grinding of toothed racks, having a workspace, in which a machining head carrying milling and/or grinding tools is movably arranged is provided. The machine further has a first preparation area arranged on a first side of the workspace, which has a first workpiece table reversibly movable from the first preparation area into the workspace, and which for its part has first positioning means for workpieces. The machine has a second preparation area, which is arranged on a second side of the workspace, and has a second workpiece table which can be reversibly moved from the second preparation area into the workspace, and which for its part has second positioning means for workpieces. A corresponding method is also provided.

Abstract

A device for grinding pre-milled and hard metal-tipped teeth of saw bands, is provided. The device comprises a feed device for feeding a temporarily formed workpiece in a timed manner, wherein the temporarily formed workpiece is formed from a plurality of saw bands which are parallel to one another. The device further comprises a clamping device which clamps the plurality of saw bands against one another, and a grinding unit for simultaneously grinding a plurality of teeth. The grinding unit comprises a grinding wheel with a plurality of grinding profiles. A corresponding method is also provided, where the grinding unit grinds both the tooth backs and the tooth faces to final dimension in exactly one linear movement.

Abstract

A device for setting saw blades has a housing, a setting device connected to the housing for setting a saw blade, a clamping device connected to the housing for clamping the saw blade, and a drive unit connected to the housing for driving the setting device and the clamping device. The setting device has saw set holders which are arranged on either side of the saw blade, are pivotable relative to one another and can be fitted with saw sets. The clamping device has clamping jaw holders which are arranged on either side of the saw blade, can be adjusted relative to one another and can be fitted with clamping jaws. In order to provide a device of the kind described above, which securely clamps the saw blade, the clamping jaw holders are designed so as to be pivotable relative to one another.
