无需熔融的激光切割机

一款皮秒激光切割器,适合于微加工应用,能够大幅减少切割加工热影响区域,返工率低,重复率高达500kHz。

Lumera Laser有限公司(德国,Kaiserslautern;www.lumera-laser.com)推出的Rapid和Super Rapid皮秒激光切割机具有多种功率制式,能够切割任何材料。由于该设备平均功率低、采用脉冲能量,因而可以对厚度小于1mm的材料进行微加工。

该激光设备在北美地区的独家供应商为RPMC公司(美国密苏里州,OFallon;www.rmpclaser.com),其总裁Chuck Ratermann先生表示:如果想要寻找切割大块金属的设备,它不是合适的解决方案。然而,对于绝大多数金属材料来说,Super Rapid 8-W激光切割机的工作速度都能够达到1mm3/min。

Ratermann先生同时认为,与纳秒激光设备相比,皮秒激光切割机具有许多优点。实例表明,纳秒激光切割可能会在玻璃或陶瓷表面留下细微裂纹,进而导致仪器故障,而皮秒激光切割却没有这种缺陷,他认为,这是因为皮秒激光在切割过程中无需熔融;另外纳秒激光切割机还会产生毛刺,需要通过后续加工步骤去除。

飞秒(1015秒)激光设备虽然和皮秒激光设备一样,具有无热影响区域的优点,但它容易受到温度和震动的影响,不适合用于工业切割。 皮秒激光切割机经过密封和热化,专为工业应用设计,操作人员可以通过控制软件,编程控制每组脉冲数量或延迟某个脉冲组。
