The present invention relates to a machining system etc. capable of highly accurately machining a workpiece even in a case where the workpiece is deflected. A machining systemis configured with a lathehaving end portion supporting mechanismsfor supporting both end portions of an elongated workpiece W horizontally, a tool restfor holding a tool, a feed mechanism for moving the tool restin three orthogonal directions, and a control devicefor controlling the feed mechanism, and a non-contact measuring devicefor measuring the deflection shape of the workpiece W when the workpiece W is rotated. The control devicemoves the tool along the deflection shape measured by the non-contact measuring device

Machining method and machining system

A machining systemcomprises a lathehaving end portion supporting mechanismsfor supporting an elongated workpiece W horizontally, center restsfor supporting the middle portion of the workpiece W, an adjustment mechanism for adjusting the supported position of the workpiece W by adjusting the height positions of the center rests, a tool rest, and a control device, and a non-contact measuring devicefor measuring the deflection amount of the workpiece W at portions thereof supported by the center restswhen the workpiece W is rotated. The control deviceis configured to adjust the height positions of the center restsby controlling the adjustment mechanism on the basis of the measured deflection amount, so that the height positions of both end portions of the workpiece W being rotated and the middle portion thereof become the same.

The present invention provides a machine tool capable of suppressing cost increase of a cover even when a long workpiece is machined. A machining unitby which the spindleis supported to be movable in X-axis, Y-axis, and Z-axis directions relative to the machining table; and a shielding mechanismprovided in said machining unitto prevent chips and coolant from scattering out of a machining area.

Machine tool

The present invention provides a machine tool realizing high-speed movement of a spindle and thus reducing the machining time without any increase in size of the whole machine. A machining unitby which a spindlewith a tool T attached thereto is supported to be relatively movable in X-axis, Y-axis, and Z-axis directions is mounted on a long bedhaving a plurality of machining areas ato aarranged in one direction, and the machining unitis movable in the arrangement direction of the machining areas.

In a double housing machining center, a table having a plurality of T slots on its top surface is arranged substantially in a horizontal direction. A lower space, into which chips are received, is provided under the table. A plurality of through-holes, being in fluid communication with bottom portions of the T slots and passing through the table to reach the lower space, is scattered and formed in the table. The chips introduced into the T slots are discharged into the lower space through the through-holes. Thus, the chips splashed down onto the table and introduced into the T slots are readily removed and the cleaning work of the table is reduced.
