技术领域
本公开涉及单晶制造技术领域，特别是涉及一种切割设备。
背景技术
现有技术中，坩埚刚熔制出来时，埚口厚薄不均、参差不齐，通常需要使用切割设备切除一段埚口，并对埚口做内外倒棱处理。
目前的切割设备通常分为两种，一种切割设备通常使用四个滚轮结构夹持坩埚，四个滚轮同时滚动的情况下，带动坩埚旋转，使用切边刀头、倒棱刀头对坩埚进行切边、倒棱处理。这种切割设备可以快速定位坩埚，但是坩埚在旋转过程中容易相对滚轮抖动，使得埚口外圆切口不平整、有台阶，造成坩埚的加工效果较差。
另一种切割设备通常使用三爪卡盘夹持坩埚，三爪卡盘夹紧坩埚后带动坩埚一起旋转。这种切割设备可以实现较好的加工效果，但是需要人工调整坩埚与三爪卡盘的同轴度，定位时间较长。也即，现有技术中的切割设备无法同时兼备加工效果好和定位速度快的特点。
