| 摘要 |
<p>The invention relates to a double face abrading machine for simultaneous removal of material from two plane-parallel surfaces of a work piece, and which comprises a first tool and a second tool (1 and 2) forming between them a machining gap (3), the first tool (1) being attached to a first shaft (5) and the second tool (2) being attached to a second shaft (7), means (11) for rotating at least one of the already mentioned first and second shafts (5 and 7) and displacement means (13 and 14) for individual axial displacement of said first and second shafts (5 and 7), for the variation of the axial size and/or position of the machining gap (3), and means for feeding the work pieces into the machining gap, where the first shaft (5) is designed as a tubular shaft which, at one end supports the first tool (1) designed with an opening (10) whose diameter at least corresponds to the diameter of the tubular shaft (5), while the second shaft (7) is arranged to extend through the first tubular shaft (5) and through the opening (10) of the first tool and exceed the first tool (1), while the second shaft (7) supports the above mentioned tool (2) so that the machining gap (3) is formed between the opposite surfaces of the first tool and the second tool (1 and 2).</p> |
