O.M.G. has projected this serie of heads to offer an adequate solution to customer exigencies, as modularity, flexibility, possibility to reuse the pieces on other projects, easy maintenance.
The following heads can reach big dimensions, transmit high powers, equip big units, special machines with automatic change of the heads, high performance production lines, and any other machine tool.
Technical featuresThe body is normally in extruded aluminium, but for particular exigencies, it is possible to have it in other materials. There are standard dimensions of round bodies in order to make easier the application of the designer, but there is the possibility to produce them with different shapes and dimensions.
The movement enters in the head from the central shaft, equipped by conical (ATC solution) or radial (standard solution) bearings at which end there is a central gear with straight shaved toothing; this transmit the movement to the conduit gears which rotate on bearings, reach the spindles which are essentially of four types: with DIN 6499 collet, DIN 55058 norm, type W.
Due to the small centre distances that this type of head can permit, in the spindles there are selected rolling, radial and axial ball bearing. The tool guide jig is suggested in all drilling operation.
The lubrication of the head is normally with long-life grease and maintenance is not necessary for 2.000 hours. If the head has to rotate at high speed, this is arranged for a micro fog lubrication (the system can be supplied by O.M.G. or bought directly by the client).
The drilling heads which require the tool guide jig can have both fix and movable columns; the drilling jigs are equipped with bushes DIN 172 or DIN 173.It is possible to supply the piece arrester equipment, studied for the exigencies of the clients.
Before delivery, all our machines are dimensionally controlled on a machine type DEA JOTA 1202 in a controlled ambient at a temperature of about 20° and with a relative humidity of 50-60%.
ReferencesSince 1987 O.M.G. has manufactured over than 2000 heads with this technique for different machine tool for world wide clients which thanks to their different enquiries have stimulated us to continuous development of this serie of heads.
