Embodiment Construction

[0031] figure 1 A schematic side view of a superfinishing machine tool according to the invention is shown. exist figure 1 In the illustrated embodiment, a superfinishing machine tool 1 according to the invention is used for superfinishing a cylindrical workpiece 3 , for example a bearing of a crankshaft.

[0032] The workpiece 3 is finished with the aid of an abrasive belt 5 , which is guided by a honing disc 7 . exist figure 1 In the shown state, the superfinishing machine tool 1 is not in contact with the workpiece 3 , and thus the abrasive belt 5 is not in contact with the workpiece 3 .

[0033] figure 1 , the clamping device 9 and the grating 11 according to the invention are arranged above the honing disc 7 . The abrasive belt is deflected below the honing disc 7 by various rollers until the abrasive belt 5 is finally guided by the transport roller 13 .

[0034] In the region of the transfer roller 13 , the abrasive belt 5 is pressed against the transfer roller 13 ...

Abstract

The invention relates to a superfinishing machine with an abrasive belt and a method for operating the same. The method probably monitors the abrasive belt (5) of the superfinishing machine and adjusts the feeding quantity of the abrasive belt (5), thus substantially saving the cost.

Description

technical field [0001] Superfinishing machine tools working with abrasive belts have been known for a long time. Superfinishing is also known as short stroke honing. Background technique [0002] In the supergrinding of workpieces, abrasive belts have two tasks. First, the surface of the workpiece is cut with sharp abrasive grains in the abrasive belt. During processing, the tips of the abrasive grains wear down and the abrasive belt becomes smooth. As a result, the grinding efficiency of the abrasive belt is reduced, and the surface of the workpiece is further polished. Each workpiece requires a new, unused length of abrasive belt. [0003] The abrasive belt transport required for this takes place between the machining of the two workpieces. For this purpose, the conveying device is controlled accordingly, which in each case includes conveying rollers. [0004] In order to be able to identify the breakage of the abrasive belt, it is common in the existing machine tool...
