Since Hypertherm doesn’t make CNC cutting machines, how do I pick the best CNC plasma table for the money?
It’s common to feel confused and even overwhelmed about how to choose the best CNC plasma table manufacturer for the money. It’s no surprise since there are as many as 100 equipment manufacturers of CNC plasma tables in the U.S. and Canada alone. Then add in the fact that these CNC plasma cutting tables or CNC plasma cutting machines can range in price quite dramatically. A low-cost hobbyist toy machine can be purchased for about $3,000, while the industrial machines used in high-production settings can exceed $200,000. Lastly, every buyer has slightly different expectations about performance. That’s why there are hundreds of model options.
In order to know how to navigate the market when you see a CNC plasma table for sale, it is important for me to explain what Hypertherm does do. We build the plasma power supplies or the CNC plasma cutters, which can range from 30 to 800 amps, and are integrated into these CNC plasma tables or machines. CNC plasma table manufacturers buy the plasma cutter, torches, and consumables from Hypertherm. We also make ancillary equipment like height control systems, CNCs, and the CAD and CAM software that drives this cutting equipment.
Next, for further clarification, we should break these CNC plasma cutting tables or machines into three general levels:
Entry level—sometimes called hobby CNC—plasma tables are ideal for the serious hobbyist or small business owner who is looking for good cut quality but does not need the CNC plasma machine to run constantly. A standard office computer or laptop will operate these CNC plasma cutting machines while basic motion control software will drive the electronics and plasma cutter torch. The size of the X-Y cutting bed for this type of machine will range from 2′ x 2′ to 5′ x 10′. When you see a CNC plasma table like this for sale, pricing will start at around $8,000 and go up to $24,000. Entry level CNC plasma cutting machines are compatible with Hypertherm’s Powermax® line of air plasma cutters. Pick your Powermax system based on the thicknesses and production levels you need.
Light industrial level
Light industrial systems are sturdier and built for low-level to moderate production. These machines are solid and will hold up for several years with minimal downtime. Like the entry level machines, some use a standard office computer or PC to drive the system, but others use an industrial level interface and servo drives for better acceleration and speed.
The size of the X-Y cutting bed averages between 4′ x 8′ and 6′ x 16′, while pricing when you see a light industrial level CNC plasma table for sale ranges from $24,000 to $50,000 or more. Hypertherm’s Powermax line of air plasma cutters are ideal for these types of machines, provided the machines are limited to non-high frequency arc starting. In addition, the MAXPRO200®, a conventional oxygen plasma, is a good choice when advanced productivity and cut quality is needed.
Industrial machines can run for multiple shifts a day in high production shops. These machines are the most complex but are the easiest to operate in thanks to the advanced software and controls used to drive the motors. All industrial systems use a servo drive system and have industrially hardened computer numerical controls. The X-Y cutting bed size can be as small as 5′ x 10′ or as large as 40′ x 350′. Pricing when you see an industrial level CNC plasma table for sale starts at $60,000 but goes all the way up to $1 million for the larger machines.
Hypertherm’s HyDefinition® and X-Definition® plasma systems, which come with a 100 percent duty cycle, are made for these types of industrial machines. Each HyPerformance® and XPR™ plasma model is rated for cutting specific metal thicknesses, but all provide excellent cut quality and can lower operating costs in high-production environments.
Here are five questions to ask yourself and your answers will help you narrow down the options:
- What size cutting bed do I need?
- How thick is most of the metal I’m cutting?
- How accurate do my cuts need to be (keep in mind higher accuracy = higher cost)?
- How much time will I spend cutting per week (plasma arc-on time)?
- How much experience do I have with CNC machines and CAD/CAM software?
Honest answers to the above questions will help you buy the best CNC plasma cutter table for the money when you see one for sale.
