Abstract (en)
[origin: EP0432637A1] The device indicated can be used particularly in the sawing of internal holes in semiconductor bars. It contains a dressing system which consists of at least one elongated dressing stone whose end face faces the cutting edge, can be moved laterally relative to the saw blade and, at the end, has two mutually opposite working faces which, during dressing, can be brought into contact laterally with that surface of the cutting edge which faces them. The device is distinguished by a low susceptibility to malfunctioning and permits dressing operations during the sawing operations.
