Abstract

A numerically controlled machine tool, including a machine bed, a cabin having a cabin wall which embraces at least part of the machine bed, and at least one shaped element, which has a substantially panel-shaped basic form and is attached to the machine tool in such a way that a cavity is present between the shaped element and the cabin wall and/or the machine bed.

First claim

1 . A numerically controlled machine tool, comprising
a machine bed which can be set up on a flat floor area, a cabin supported by the machine bed, and a shaped element, which covers a lower portion of the machine bed, at least between the flat floor area and a cabin wall of the cabin, wherein the shaped element mounted on the machine tool in such a way that a cavity is formed between the machine bed and the shaped element.

2 . The machine tool according to claim 1 , wherein
the shaped element extends substantially from the flat floor area to an upper portion of the machine bed in such a way that an upper portion of the shaped element is arranged between the machine bed and a lower portion of the cabin.

3 . The machine tool according to claim 2 , wherein the lower portion of the cabin is in contact with the shaped element.

4 . The machine tool according to claim 1 , wherein
the shaped element covers the lower portion of the machine bed, at least along a front side of the machine bed.

5 . The machine tool according to claim 1 , wherein
the shaped element covers the lower portion of the machine bed along two or more sides of the machine bed.

6 . The machine tool according to claim 1 , wherein
the shaped element covers the lower portion of the machine bed so as to fully embrace the machine bed.

7 . The machine tool according to claim 1 , wherein
the shaped element is made of metal and/or a plastic material.

8 . The machine tool according to claim 1 , wherein
the shaped element comprises one or more extruded profiled sheets, which are adapted to an outer form of the machine bed.

9 . The machine tool according to claim 1 , wherein
the shaped element a surface coating made from a coating material which has a thermal conductivity that is below the thermal conductivity of the material of the shaped element.

10 . The machine tool according to claim 9 , wherein
the surface coating is provided on a surface of the shaped element which faces the cavity.

11 . The machine tool according to claim 1 , wherein
the shaped element is attached to the machine bed by means of a plurality of attachment elements, wherein the attachment elements extend from the shaped element through the cavity to the machine bed.

12 . The machine tool according to claim 11 , wherein
the attachment elements are made from a material which has a thermal conductivity that is below the thermal conductivity of the material of the shaped element.

13 . The machine tool according to claim 1 , wherein
the shaped element has recessed portions, as a result of which the distance of the shaped element in relation to the machine bed varies, wherein the recessed portions are formed on a lower edge of the shaped element.

14 . The machine tool according to claim 1 , wherein
a rubber lip is attached along a lower edge of the shaped element and is adapted to seal a gap between the lower edge of the shaped element and a flat floor area.

15 . The machine tool according to claim 1 , wherein
the machine bed has machine bed feet extend horizontally outwards and serve to rest on the flat floor area, wherein the shaped element has recesses, through which the machine bed feet extend.
