More and more shop owners are deciding that CNC plasma-cutting tables are great additions to their shops. The computer-controlled robotic arm can guide the plasma torch over the surface of the work to create intricate and complex cutting patterns.

凭借如此精确的削减能力,赚钱的可能性是无限的。在贸易展览和美术馆中创建待售金属艺术;轻松创建复杂的HVAC管道;创建概念部分的原型;创建一次性或难以找到机械零件。但是,购买CNC计算机并不像跑到五金店并捡起一台机器那样容易。您需要考虑一些问题,以帮助您更轻松地购买决策。通过事先进行仔细的研究,您可以节省自己和公司的大量时间和费用。

MACHINE QUALITY
首先,要确保的第一件事是您要获得一台高质量的机器。CNC等离子体切割桌(无论制造商如何)都是昂贵的。事先做作业,并确保您获得预算允许的最高质量。

材料
您需要检查框架构造中使用的材料的质量。是钢吗?铝?还有其他吗?当然,钢比铝强,因此钢铁机将需要更少的材料,并且会更轻,但看起来会脆弱。铝机将更加笨重,但具有强度的外观。由两种材料制成的机器甚至可以为最大的工作提供足够的力量。

设计
You’ll want to check on the quality of the table design. So many factors can affect the performance of the table, and the slightest variation in even the smallest factor can alter table performance. For example, if the gantry (the big heavy bar that slides up and down the length of the table) is too heavy, it makes the torch difficult to control with high speed and accuracy. A light-weight gantry, on the other hand, can produce amazingly accurate results at high speeds.

Also consider rolling surfaces. Sealed ways keep out more dust and grit, but they can’t keep out all of the inevitable plasma dust Eventually the dust will mix with the oil and create a gritty sludge that will chew up the parts. Because it’s sealed, you’ll have to replace the entire component. Unsealed parts, however, are much simpler. An unsealed roller on a simple way can be wiped completely clean in a second, and should a part need to be replaced, it can be accessed without replacing the entire component.

Motors
什么样的电动机控制火炬?伺服电动机被广泛认为优于步进电动机。伺服电机可以在其运动范围内移动到无限数量的位置,并向控制器提供反馈,告诉控制器目前恰好在哪里。步进电动机具有可以移动的有限位置,也没有向控制器提供反馈。因此,有时会碰巧控制器会告诉步进电动机移动一定数量的步骤,但是控制器无法知道是否确实发生了请求的运动。

If the torch hit a snag or otherwise didn’t move for some reason, the entire cut path will be offset from where the controller thinks it is. Of course, servo motors are more expensive than stepper motors. Just take care that your attempts at cost-cutting don’t hamper your ability to cut quality designs.

软件
The software that runs the equipment and designs the drawings is arguably the most important component of your CNC plasma table setup. The software performs two distinct functions: designing the piece to be cut, and controlling the table and the plasma cutter. Although high-end design software like AutoCAD is perfect for creating high quality designs for a large number of applications, be careful you’re not using a sledgehammer to swat a fly.

AutoCAD and the like have built-in functions to handle extremely complex requirements, and often those extra functions can distract the user and actually inhibit the creation of perfect cut-paths. A better option is to look for software specifically designed for creating CNC plasma cutting drawings. This software is optimized for making perfect cut-paths, and can do so quickly and easily. Controlling the table and the plasma cutter must be performed by the software that came with your table. The best software will be created to maximize the characteristics of the table it’s running on.

Be sure to look for software created and optimized specifically for your table. Ideally, the software running the table should be written by the same company that makes the table. This will help you avoid the all too common response “that’s not our problem, call the software vendor” if you ever have to call for technical support.

DUST AND SMOKE
Plasma cutting produces a hefty amount of dust and smoke. Without proper ventilation or other dust-containment measures, the dust and smoke can quickly overtake an enclosed room. Most cutter manufacturers recommend their cutters not be used outdoors, which means you’ll have to provide your own indoor containment measures.

Downdraft
A downdraft system consists of skirts around the base of the table that enclose all the area under the table, and a fan that sucks air down through the table and outdoors (or through your air-filtration system, if you’re recirculating the air). This is a very simple and effective system for eliminating dust and smoke, but typically must be custom configured for each installation. When comparing tables, be sure to ask about a downdraft system. Does the machine come with downdraft components, and if so, are they stock components or can they be customized?

地下水位
A water table is another dust and smoke containment system, consisting of a shallow table of water placed under the cutting surface of the table. As the machine is cutting the metal, sparks and dust are blown down into the water where they are quickly doused. When using a water table, be extra careful to keep all electrical components away from the water. Also be sure to ask the table manufacturer if water tables are recommended with their cutting tables. Water can splash, and sometimes the underside of the cutting table can become rusty with excessive or incorrect use.

FINALLY . . .
最后但并非最不重要的一点是,请务必查看桌子随附的保修。公司会站在其产品后面吗?较长的保修期比短期保修期更好。保修是否涵盖所有零件,或仅涵盖某些零件?如果保修到期后出了问题,会发生什么?替换零件的成本是多少?

当您比较所有选项并回答所有这些问题(以及其他特定于您唯一设置的问题)时,您将处于明确的位置,可以进行明智的购买。不再需要将您的切割项目带到整个城镇的商店应该节省大量时间和费用,甚至可能使您成为其他人的切割项目。

    I liked that you said that a downdraft system can eliminate smoke and dust. My uncle wants to get a new plasma cutting system and he’s worried about removing any indoor containment in his factory. He should look for a system that has a lot of skirts and has updated software.http://www.esseng.com.au/aircannons

    You got my attention when you said that you must consider having your own indoor containment measures as plasma cutting produces a big amount of dust and smoke. I would imagine industrial construction companies using this kind of equipment. They would be sure of their workers’ safety if they would consider the ventilation of the working area.https://www.wayneoxygen.com/welding-equipment
