ISO 23125:2014规定了消除以下几组车床和车削中心危害或降低风险的要求和/或措施，这些车床和车削中心主要设计用于通过切削成型金属。 第1组:无数控的手动控制车床。 第2组:数控能力有限的手动控制车床。 第3组:数控车床和车削中心。 第4组:单轴或多轴自动车床。 它涵盖了重大危险，并适用于机器不可或缺的辅助设备（例如工件、工具和工件夹紧设备、搬运设备和切屑搬运设备）。ISO 23125:2014也适用于集成到自动生产线或车削单元中的机器，因为产生的危害和风险与单独工作的机器相当。

ISO 23125:2014 specifies the requirements and/or measures to eliminate the hazards or reduce the risks in the following groups of turning machines and turning centres, which are designed primarily to shape metal by cutting.

• Group 1: Manually controlled turning machines without numerical control.
• Group 2: Manually controlled turning machines with limited numerically controlled capability.
• Group 3: Numerically controlled turning machines and turning centres.
• Group 4: Single- or multi-spindle automatic turning machines.

It covers the significant hazards and applies to ancillary devices (e.g. for workpieces, tools and work clamping devices, handling devices and chip handling equipment), which are integral to the machine. ISO 23125:2014 also applies to machines which are integrated into an automatic production line or turning cell inasmuch as the hazards and risks arising are comparable to those of machines working separately.
