Abstract
A machine tool comprises: (a) a tool (22); (b) a body (2); (c) a tool supporting means (10) for supporting the tool (22) provided relative to the body (2); (d) a means (4) for supporting a pallet (P) for setting a work (W), the support means (36, 35) being provided relative to the body (2); (e) a first moving means (31, 32, 32a, 33, 34, 37, 39) for moving the means (4) about a center axis (U2) along a first direction (B1, B2); and (f) a second moving means (11, 12, 13, 14, 15, 16, 17, 18, 19, 20) for moving the tool supporting means (10) so as to cause relative motion between the tool supporting means (10) and the means (4) for performing machining operation of the work (W).
Claims19
A machine tool comprising:
- (a) a tool (22);
- (b) a body (2) comprising a C-shape member (38) with an arc-shape guide groove (39);
- (c) a tool supporting means (10) for supporting the tool (22) wherein said tool supporting means (10) is movable with respect to said body (2);
- (d) a work operating means (4) for supporting a pallet (P) for setting a work (W), wherein the work operating means (4) comprises a base (35) provided with rollers (37) for interaction with the guide groove (39) and is movable with respect to the body (2);
- (e) a first moving means (31, 32, 32a, 33, 34, 37, 39) for moving the base (35) along the guide groove (39) such that the work operating means (4) moves about a center axis (U2) along a first path (B1, B2);
- and
- (f) a second moving means (11, 12, 13, 14, 15, 16, 17, 18, 19, 20) for moving the tool supporting means (10) so as to cause relative motion between the tool supporting means (10) and the work operating means (4) for performing a machining operation of the work (W).
