MACHINING DEVICE FOR MACHINING FINEWORK TECHNICAL, IN PARTICULAR DENTAL TECHNICAL WORKPIECES IN A WORKING AREA SURROUNDED BY A HOUSING

摘要

In a processing apparatus (1) for processing fine technical workpieces in a machining chamber (31) surrounded by a housing (2) which is accessible manually through two grip-through openings (36) and visually through a viewing window (23) in the housing (2), and in which at least one blasting nozzle (52a, 52b, 52c), particularly of a one-way abrasive blasting device, is arranged for abrasive blasting of the workpieces, which is connected via a supply line (53a, 53b, 53c) with the interior of a preferably cylindrical blasting agent container (17a, 17b, 17c), the machining chamber (31) being separated by partitions from the hollow space (81) of the housing (2), and the blasting agent container (17a, 17b, 17c) being arranged in the hollow space (81) of the housing (2) by means of a support part (16) carrying the container and being chargeable through a charging opening in the housing wall which can be sealed by a closure wall, the supply line (53a, 53b, 53c) is flexible at least in the region of the cavity (81), the support part (16) is adjustable with the blasting agent container (17a, 17b, 17c) between its working position located in the housing (2) through the charging opening into a charging position in which the blasting agent container (17a, 17b, 17c) is arranged outside the housing (2) at least with its charging opening, but preferably completely. …IMAGE…
