Title:
WORKPIECE SUPPORT OF A MACHINE TOOL FOR MACHINING WORKPIECES AND MACHINE TOOL HAVING A WORKPIECE SUPPORT
Document Type and Number:
WIPO Patent Application WO/2019/115715
Kind Code:
A3
Abstract:
The invention relates to a workpiece support (8) of a machine tool for machining workpieces, comprising a flat workpiece support element (9) and a suction device (14). During the machining of a workpiece, the workpiece is mounted on a workpiece side (12) of the workpiece support element (9). Towards a lower side opposite the workpiece side (12), the workpiece support element (9) is permeable to a waste air flow loaded with machining-related emissions. The suction device (14) comprises a vacuum generator and a suction line (21). The vacuum generator of the suction device (14) can generate the waste air flow flowing from the workpiece side (12) to the underside of the workpiece support element (9), can suction into the suction line (21) in a flow direction and can subsequently discharge via the suction line (21). The suction line (21) has a suction opening (31) on the support element side arranged downstream of the workpiece side (12) of the workpiece support element (9) and has a flow cross section which can be passed by the waste air flow in the flow direction. The opening width of the flow cross section of the suction opening (31) of the suction line (21) can be variably adjusted. In addition or alternatively, the position of the suction opening (31) on the suction line (21) can be variably adjusted. A machine tool for preferably thermal machining of workpieces is provided with a workpiece support (8) of the above-mentioned type.
