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.
