<p>A cutting device (201) comprising:
a table (2) having a table surface for placing thereon a workpiece (W);
a tool unit (10);
a cutting tool (12) mounted to the tool unit (10) and having a rotational axis; a pivotal support device (20) mounted on the table (2) and supporting the tool unit (10), so that the tool unit (10) can be laterally tilted to incline the rotational axis of the cutting tool (12) relative to the table surface,
wherein the pivotal support device (20) comprises a base member (21) mounted to the table (2) and a support member (22) configured to support the tool unit (10) and coupled to the base member (21), so that the support member (22) can rotate relative to the base member (21) about a rotational axis; and
first and second positioning devices (40A, 40B) each configured to be able to position the tool unit (10) at any one of a plurality of laterally tilted positions;
wherein each of the first and second positioning devices (40A, 40B) includes a first member (233 or 241) and at least one second member (B2, B3 or B4, B5, B6, B7);
wherein the first member (233 or 241) is moveably mounted to one of the base member (21) and the support member (22); and
wherein the at least one second member (B2, B3 or B4, B5, B6, B7) is mounted to the other of the base member (21) and the support member (22), so that the first member (233 or 241) can contact the at least one second member (B2, B3 or B4, B5, B6, B7) to position the tool unit (10) at different laterally tilted positions depending on the position of the fist member (233 3 or 241).</p> |
