The English text on this page summarises the model and specifications. The full technical description is the Chinese original below; an English datasheet is available from our engineers on request.

金相切割机主要用于金相试样的取样或者岩相取样（岩相配金刚石切割片） ，若取样不当，则达不到检验目的，因而选择适合的切割机，对取样工作非 常重要。对金相切割机的选型一般以被取样材料的规格大小为参考，如小 件可以选用小切割直径的金相切割机，相对较大的工件可以选用切割范围 较大的切割机。根据被取样材质的不同，选配不同的切割片，以便达到最 理想的取样目的。 二、性能特点 1、超大的切割室 2、手动切割方式 3、自动冷却系统，避免试样块烧伤 5、封闭式切割 7、双夹具加紧结构 8、主机、冷却系统分体式 三、技术参数：
