Economic considerations when purchasing a jet cutting machine
Thinking about purchasing a jet cutting system? Many factors should be considered before deciding which system to buy. This article discusses fixed and operating costs and productivity and provides the framework for making an intelligent buying decision.


The purpose in buying machinery is to make money with it. Buying nothing costs nothing, but makes no money. A premium jet cutting machine costs more than a standard machine, but the better machine usually is designed to enhance productivity. The equipment must match the work it is intended to do. When deciding which machine to purchase, a buyer must strike the balance between price, productivity, and machine capability.
Matching the Machine to the Work
A job shop and a manufacturer have slightly different considerations when choosing a jet cutting machine. The manufacturer knows exactly which parts he will be making and the production volumes. Some factors for the manufacturer to consider are:
· A small machine with low accuracy may match the work to be done perfectly.
· A large machine can achieve material savings via nesting and lower unit cost of material in large sheets.
· An accurate machine often can eliminate secondary operations.
A job shop owner is concerned with these factors as well, but he also may worry that his machine will be too small for the work his customers might request. He tends to buy a machine for the largest imaginable part. Machine accuracy sometimes is overlooked, but customers prefer precise parts that require little or no secondary processing. The shop's revenue depends on the ability to produce the parts the customer wants.
Jet Cutting Costs
Costs include capital costs that are fixed, no matter how much the machine is operated, and those determined by the machine's operating time. Let's consider two shops to see the effects of these two costs. The first shop operates its machine part-time, about 24 hours each week. The second shop operates two shifts and runs the machine 70 hours weekly. We will use these operation times to calculate the hourly capital cost and the hourly operating costs.

经济的考量当购买一部喷气式飞机切断机器的时候
在想购买减低系统的喷气式飞机? 许多因素在决定该买哪一个系统之前应该被考虑. 这一个文章讨论修理而且操作费用和生产力而且提供作出聪明的买决定的架构.
翻译结果：目的在买机器方面将以它赚钱. 毫不买无费用, 但是没有赚钱. 高级的喷气式飞机锐利的机器值比一部标准的机器更多, 但是较好的机器通常被设计提高生产力. 设备一定相配它预计的工作做. 当决定该购买哪一个机器的时候,一个买主一定在价格、生产力和机器能力之间袭击平衡.
相配机器给工作
当选择喷气式飞机锐利的机器时候,一家工作商店和一个制造业者有些微不同的考量. 制造业者完全地知道哪一个部份他将会制造和生产体积. 一些因素让制造业者考虑是:
· 一部小的机器用低的准确性可能相配工作完全地被做.
· 一部大的机器经由筑巢能达成物质的储蓄和在大的床单中的材料的比较低的单位费用.
· 一部正确的机器时常能除去中级的操作.
一个工作商店拥有者和这些因素有关也,但是因为工作他的客户可能请求,他也可能烦恼那,他的机器将会太小. 他容易为最大的可想像的部份买一部机器. 有时以机器制造准确性被俯看, 但是客户偏爱需要很小的或甚至没有中级的处理的精确的部份. 商店的收入仰赖能力生产那分开客户需要.
喷气式飞机切断费用
费用包括被修理的首都的费用, 没有物质多少机器被操作, 和在机器的操作的时间之前被决定的那些. 让我们考虑二家商店见到这些的效果二费用. 第一家商店部分时间操作它的机器, 每个星期的大约 24 小时. 第二家商店操作二变化而且使用机器 70 小时周刊. 我们将会使用这些操作时代计算每小时的首都费用和每小时的操作费用.
