This, of course, has the disadvantage that the two grinding heads must be precisely tuned to each other in their work, that is to say must be synchronized

Embodiment Construction

[0023] exist figure 1 A grinding machine 1 is shown in the figure, which is preferably used for grinding saw blades 2 during the manufacturing process. Saw blade 2 is a saw blade equipped with carbide, as in image 3 with Figure 4 shown schematically and in other proportions and parts. Each tooth 3 of the saw blade 2 is provided with a cemented carbide head 4 which is located above the planar side of the tooth 2 at least in the axial direction; Figure 4 As can be seen in , the carbide head protrudes beyond the serration in the radial direction.

[0024] The carbide head 4 is substantially cuboid-shaped, wherein the radially outwardly pointing plane of the carbide head defines a tooth back 5, and the two axially directed side planes of the carbide head define the tooth flanks 6, 7 . On the front side of the tooth 2 , the hard metal head 4 defines a toothed end face 8 with its front side.

[0025] Grinding of the tooth back 5 and tooth flanks 6 , 7 is required even for t...

Abstract

A grinding machine is designed as a multi-station grinding machine, which has two complete grinding stations. The grinding stations have grinding heads, which can be moved by means of appropriate positioning devices, for example compound table arrangements, and / or pivot tables, in relation to the saw blade. Positioning devices and arresting devices for the workpiece are furthermore parts of the grinding stations. The workpiece support is used for positioning the saw blades to the extent that their center axis (M) is to be fixed in the grinding. The rotation of the saw blades around this center axis (M), and the clamping in place of the saw blade in the respective rotated position for performing the grinding operation is the task of the respective units in the grinding stations. A very rapid and precise, and therefore cost-effective, processing of saw blades is possible by means of a grinding machine designed in this way. The grinding machine is particularly suited for sharpening saw blades in the course of their manufacture.

Description

technical field [0001] The present invention relates to a grinding machine, in particular for sharpening saw blades themselves during their manufacture. Background technique [0002] Saw sharpening machines are known which have one or more grinding heads with which the teeth of the saw blade are brought into the desired shape. It is also known that multiple grinding heads are required. For example, a second grinding head is known which has a first grinding wheel for the back of the tooth and a grinding wheel for the end face of the tooth. The saw blade must be machined tooth by tooth, for example first the back of the tooth and then the face of the tooth. Always after grinding a sawtooth, the saw blade is rotated further precisely over a sawtooth by means of a corresponding positioning mechanism. The time required for machining the saw blade is the time required for two saw blade cycles. This time can be shortened if separate grinding heads are provided for the tooth fla...
