激光切割机切割直线导轨的九大标准是什么呢?

永利总站/ 日期:2019-06-26 发布人:admin

  工业用激光切割机内主要的传动部件是滚珠丝杆和直线导轨,激光切割机切割质量的九大规范是什么呢?下面给大家列出了九项事项,大家能够作为参考。

  The main transmission parts of industrial laser cutting machine are ball screw and linear guide. What are the nine standards for cutting quality of laser cutting machine? Here are nine items for your reference.
  1.粗糙度。激光切割断面会构成垂直的纹路,纹路的深度决议了切割外表的粗糙度,越浅的纹路,切割断面就越润滑。粗糙度不只影响边缘的外观,还影响摩擦特性,大多数状况下,需求尽量降低粗糙度,所以纹路越浅,切割质量就越高。
  1. Roughness. Laser cutting section will form a vertical grain, the depth of the grain determines the roughness of the cutting surface, the shallower the grain, the more lubricated the cutting section. Roughness not only affects the appearance of edges, but also affects the friction characteristics. In most cases, the need to minimize roughness, so the shallower the grain, the higher the cutting quality.
  2.资料堆积。激光切割机在开端凝结穿孔前先在工件外表碰上一层含油的特殊液体。切割过程中,由于气化且各种资料不用,客户用风吹除切口,但是向上或向下排出也会在外表构成堆积。
  2. Data accumulation. The laser cutter first encounters a special layer of oil-containing liquid on the surface of the workpiece before it starts to condense and perforate. In the cutting process, due to the gasification and various data are not used, the customer uses the wind to remove the incision, but the upward or downward discharge will also form a accumulation on the surface.
  3.凹陷和腐蚀。凹陷和腐蚀对切割边缘的外表有不利影响,影响外观。他们呈现在普通本应防止的切割误差中。
  3. Depression and corrosion. Depression and corrosion have adverse effects on the appearance of cutting edge and affect the appearance. They appear in the cutting errors that should be prevented in general.
  4.毛刺。毛刺的构成时决议激光切割质量的一个十分重要的影响要素,由于毛刺的去除需求额外的工作量,所以毛刺量的严重和几是能直观判别切割的质量。
  4. Burrs. Burr formation is a very important factor affecting the quality of laser cutting. Because the removal of burr requires extra work, the severity of burr amount and the quality of cutting can be judged intuitively.
  5.热影响区域。激光切割中,沿着切口左近的区域被加热。同时,金属的构造发作变化。例如,一些金属会发作硬化。热影响区域指的是内部构造发作变化的区域的深度。
  5. Heat-affected zone. In laser cutting, the area near the left of the incision is heated. At the same time, the structure of the metal changes. For example, some metals harden. The heat-affected area refers to the depth of the area where the internal structure changes.

  6.垂直度。如何钣金的厚度超越10mm,切割边缘的垂直度十分的重要。远离焦点时,激光束变得发散,依据焦点的位置,切割朝着顶部或者底部变宽。切割边缘偏离垂直线百分之几毫米,边缘越垂直,切割质量越高。
  6. Verticality. How the thickness of sheet metal exceeds 10 mm, the verticality of cutting edge is very important. When away from the focus, the laser beam diverges and, depending on the position of the focus, cuts wider toward the top or bottom. The cutting edge deviates from the vertical line by several millimeters. The more vertical the edge is, the higher the cutting quality is.
  7.变形。假如切割使得部件急剧加热,它就会变形。精密加工中这一点尤为重要,由于这里的轮廓和衔接片通常只要非常之几毫米宽。控制激光功率以及运用短激光脉冲能够减少部件变热,防止变形。
  7. Deformation. If the cutting causes the parts to heat sharply, it will deform. This is particularly important in precision machining because the contours and joints here are usually only a few millimeters wide. Controlling laser power and using short laser pulses can reduce the heating of components and prevent deformation.
  8.切割宽度。切口宽度普通来说不影响切割质量,仅仅在部件内部构成特别精细的轮廓时,切割宽度才有重要影响,这是由于切割宽度决议了轮廓的较小内经,当板材厚度增加时,切割宽度也随之增加。所以想要保证同等高精度,不论切口宽度多大,工件在激光切割机的加工区域应该是恒定的。
  8. Cutting width. Generally speaking, cutting width does not affect cutting quality, but only when a particularly fine contour is formed inside the part, the cutting width has an important effect. This is because the cutting width determines the minimum inner meridian of the contour, and when the thickness of the plate increases, the cutting width also increases. Therefore, in order to ensure the same high accuracy, no matter how wide the cut width, the workpiece in the laser cutting machine processing area should be constant.
  9.纹路。高速切割厚板时,熔融金属不会呈现于垂直激光束下方的切口里,反而会在激光束偏后处喷出来。结果,弯曲的纹路在切割边缘构成了,纹路紧紧跟随挪动的激光束,为了修正这个问题,在切割加工结尾时降低进给速率,能够大大消弭纹路的行成。
  9. Patterns. When cutting thick plates at high speed, molten metal will not appear in the incision under the vertical laser beam, but will eject at the back of the laser beam. As a result, the curved lines are formed at the cutting edge and follow the moving laser beam tightly. To correct this problem, reducing the feed rate at the end of the cutting process can greatly eliminate the formation of the lines.
