Machine tool having cable guide apparatus

A numerically controlled machine tool (10) having a cable guide apparatus (100) for providing and guiding a flexible connection cable (101) of a cable-connected tool (12), said machine tool (10) comprising at least:

• a machining apparatus (11) configured to receive the cable-connected tool (12),
• one or more numerically controlled machine axes configured to position the machining apparatus (11) and a workpiece to be machined relative to one another, and the cable guide apparatus (100) comprises:
• a first guide apparatus (110),
• a slide (111) movably guided in the first guide apparatus (110),
• a first deflection roller (103) rotatably connected to the slide (111),
• a first tension weight G1 (121),
• a cable pull apparatus (130) connecting the first tension weight G1 (121) to the slide (111) guided in the first guide apparatus (110),
• wherein the connection cable (101) runs over the first deflection roller (103) and connects the cable-connected tool (12) to a connection apparatus (102) of the machine tool (10),
• wherein
• the cable guide apparatus (100) further comprises:
• a second tension weight G2 (122), and
• a second guide apparatus (120) in which the tension weights G1 (121) and G2 (122) are each guided in a movable manner,
• such that the connection cable (101) running over the first deflection roller (103) is pretensioned in a first displacement region of the cable-connected tool (12) by a force generated by the weight of the first tension weight G1 (121) and
• is pretensioned in a second displacement region of the cable-connected tool (12) by a force generated by a sum of the weights of the tension weights G1 (121) and G2 (122).
