A cable guide apparatus including a guide apparatus, a slide movably guided in the guide apparatus, a deflection roller connected to the slide, a first tension weight, a cable pull apparatus which connects the first tension weight to the slide guided in the guide apparatus, wherein the connection cable has a free end and a fixed end connected to a connection apparatus and extends over the deflection roller, a second tension weight and a second guide apparatus in which the tension weights are each movably guided, such that the connection cable extending over the deflection roller is preloaded in a first displacement region of the free end by a force generated by the weight force of the first tension weight and is preloaded in a second displacement region of the free end by a force generated by a total of the weight forces of the tension weights.

Machine tool having cable guide apparatus

An optical module for a machine for machining workpieces and/or for producing molded bodies by location-selective solidification of material powder to form connected regions by a focused laser beam includes a housing for releasably attaching the optical module to the machine and a plurality of optical components are arranged in or on the housing to collimate and focus the laser beam.

Exchangeable optical module for a laser machining machine

An optical module for a machine for machining workpieces and/or for producing molded bodies by way of location-selective solidification of material powder into contiguous regions by a laser beam includes a housing for releasably fastening the optical module to the machine and a collimation optics changer releasably arranged in the housing, having at least two collimation optics which can be moved into a beam path of the laser beam for collimating the laser beam. The collimation optics changer has a mechanism for automatically changing the collimation optics.

Optical module having a device for automatically changing a collimation optic

A machine for machining workpieces and/or for producing molded bodies by location-selective solidification of material powder to form connected regions by means of a focused laser beam, including: a process chamber which can be closed by a process chamber door and which encloses a process space, a material powder container cabinet, which can be closed by a door, for storing material powder, and a suction system. The suction system has a fan for generating an air flow, a first suction apparatus fluidically connected to the fan by a first waste air duct to suction particles out of the process space, and a second suction apparatus fluidically connected to the fan by a second waste air duct to suction particles out of the material powder container cabinet. The first suction apparatus has means for controlling its suction power and/or the second suction apparatus has means for controlling its suction power.
