摘要： The drilling apparatus comprises a drilling device (1) that is intended to be fed into a hole to be drilled, which comprises a casing part (2) essentially inside of which there is at least during a drilling situation a drilling unit (3). In the drilling head (I) of the drilling unit (3) there are at least a first drilling means (4) for drilling a center hole (R) and a second drilling means (5) for reaming the center hole (R) for the casing part (2) as well as a flushing means (6) for removal of the drilling waste. The rotational movement (w4) around the longitudinal axis (s) and the impact movement (t4) in the longitudinal direction of the first drilling means (4) is transmitted by a counterpart assembly (V) to the second drilling means (5) essentially at the drilling head (I) of the drilling unit (3). The second drilling means (5) is arranged to rotate in connection with the head (I') of the casing part (2) centrically around the longitudinal axis (s) by a coupling assembly (L) and it is in addition arranged detachable from the second drilling means (5) for removing the first drilling means (4) from the prepared hole. For optimizing at least the size of the first drilling means (4), the effective diameter (Rd) of the first drilling means (4) is at least 60 %, preferably more than 75 % of the inner diameter (2d) of the casing part (2).

摘要： The invention relates to a method for drilling, being carried out by a drilling apparatus, having a drilling device (1) that comprises a casing part (2) and a drilling unit (3), in the drilling head (I) of which there are first drilling means (4) for drilling a center hole and second drilling means (5) for reaming of the center hole for the casing part (2) as well as flushing flow arrangement (6) for flushing of waste, being generated. At least during the drilling situation, the first drilling means (4) are coupled by a power transmitting and, in order to enable removal of the same from the hole, removable arrangement, such as a bayonet coupling or like, with the second drilling means (5). A feed flow (6a) of flushing medium, being carried out centrally, is being transferred by internal drillings (X1) inside a first frame part (4a), belonging to the first drilling means (4), to its outer periphery and a return flow (6b) of flushing medium, in order to accomplish a so called reverse circulation of flushing medium, from the drilling surface (pp2) of the first frame part (4a) through internal drillings (X2) therein into a space (z) between the first frame part (4a) and the casing part (2). The invention relates also to a drilling apparatus for exploitation of the method described above.

摘要： An apparatus for grinding surfaces comprising a frame (1, 2), machine tools (3, 4, 5, 6, 7) attached to the frame, and several bearing elements (11, 12, 13, 14, 15, 16) attached to the frame which include a bearing surface (20) leaning on the surface to be ground and/or some other stop surface (T1, T2, T3) and adapted to its shape, and equipment for forming an air or liquid cushion between said bearing surface (20) and stop surface (T1, T2, T3). In an apparatus of the present invention, the attachment of at least one bearing surface (11-16) to the frame (2) comprises controllable adjusting equipment (18) for adjusting the position of the bearing surface (20) in relation to the frame. The present invention provides an apparatus which is especially adapted for grinding surfaces in massive constructions on site. The apparatus may be used in a versatile way, and work may be initiated and carried out quickly without any large-scale preparations.
