Abrégé

A machining center includes two independent carriages supported so that they can slide along respective longitudinal translation axes by two parallel horizontal rails fixed in a raised position to a supporting structure. The carriages support respective machining heads which can move along two respective translation axes. The machining heads support respective tool holding spindles in a rotatable manner about a horizontal rotation axis (Yr′, Yr″) by virtue of rotary support means. A workpiece holding table is supported at the base of the supporting structure. Two mechanized tool magazines are supported at the opposite longitudinal ends of the supporting structure and are accessible by the spindles. The rotary support and/or the workpiece holding table can rotate about a respective vertical axis.

A machining center includes two independent carriages that are supported so that they can slide along respective longitudinal translation axes by a pair of parallel horizontal rails which are extended along a longitudinal direction and are fixed in a raised position to a supporting structure. Each one of the carriages supports a machining head which can move along a transverse translation axis and along a vertical translation axis by guiding components. Each of the machining heads supports a tool holding spindle so that it can rotate about a horizontal rotation axis by rotary support components. A workpiece holding table is supported at a base of the supporting structure so that it can rotate about a first rotation axis which is extended in a horizontal and longitudinal direction. Two mechanized tool magazines at the opposite longitudinal ends of the supporting structure are accessible by the spindles.

In a machining center provided with a mechanized tool magazine (32) and with at least one movable tool-holding spindle (18, 20) capable of accessing the tool magazine (32), the tool is picked up from the tool-holding spindle (18, 20) and transferred to a tool replacement area (38) by means of a dedicated, automatic transfer device (34) that is independent of the tool magazine (32). After the replacement of the tool with a new tool in the transfer device (34), the new tool is returned to the tool-holding spindle (18, 20) by means of the transfer device (34).

A sensor detects an axial position of a rod controlling a tool-gripping collet in a tool-holding spindle whenever a tool is picked during a working session. The current obtained rod position value is compared with previous rod position value, which has been obtained and stored during the previous tool-picking and, if their deviation is larger than a predetermined threshold, the collet closure is notified as defective. The rod position is obtained as an average of a plurality of closely spaced readings, which are taken after a predetermined delay from the collet closure.
