<p>The milling machine, provided with a photoelectric reader, is intended to allow adjustment of the reduction/multiplication factor for the pattern from between 1:1 and 1:100 and at the same time have a high precision and output. The machine consists of a reading head (9) which can be moved in the direction of X and Y coordinates marked on the pattern table (10). The reading head is attached to a support arm (8) which is connected to a mobile machine slide (5), both these being held in guides on the machine framework (1). For 1:1 correspondence the connection is a rigid link, whereas for reduction from the pattern, the connection can either be a pantograph or an electronic reduction unit.</p> |
