Things that you need to contemplate for a Water Jet Tile Cutting Machine.

Things that you need to contemplate for a waterjet cutting machine.
Written by Pradeep Kumar

Hey, are you ready with your manufacturing business plan? – Is it in the marble or glass manufacturing industry? So whatever it is, do you need a waterjet cutting machine, depending on your business, be it a water jet tile cutting machine or a water jet glass cutting machine? So, before collecting these cutting devices you need to know certain aspects about buying this item.

First, don’t inevitably assume significant brands when it comes to getting the right solution. Next, don’t rush into attractive offers or features you don’t need. Finally, make sure you discuss what you need before looking for such a machine and decide accordingly. So, knowing these basic dos and don’ts can save you your dollars and years of frustration.

So, what you need to understand before jumping into it is:-

1. It’s messy: – Along with high water pressure to grind through the components of these cutting machines use a harsh medium (Garnet) mixed. The outcome? – Garnet particles + metal grindings + water = a sandy muddy mess.

2. Easy: – It’s Easy – Throw material on the table, position the nozzle and start the cut for any material or any thickness.

3. It’s Expensive – Waterjet shape-cutting is at the upper end of the machining processes at an operating cost of about $30 per hour (see: Waterjet Capabilities: Where Waterjets Fit).

4. Versatile – Waterjets can cut any material to close tolerances with minimal setup and little to no programming expertise smoothly offsetting those operating costs with profits in the $150 per hour and + range.

What size of the machine will suit you?

Between a water jet tile cutting machine and a water jet glass cutting machine, which type of machine you select is up to you, but choosing the right size is very important. Generally, we can pick a machine base on system price, available floor space, and the size part we currently had determined, but that doesn’t mean that the product will be purchased in larger sheets or that we will pay an additional premium for more inferior material sizes. It is not our concern to be shared. The biggest mistake from the start was choosing a machine size of 2X4 or 4X4, which would have been better by preferring a 5’x10′ or larger machine because most users really need this size.

Owing to this, the production of machine tools required a system of controls, drives, servos, rails, gearboxes, etc. these elements are all very much identical on a 2’ X 4’ machine as they are on a 6’ X 12’ system. Making a powerful system costs just a few thousand more in elements and labor compared to a more undersized system. While the manufacturers categorized these giant machines at much higher prices, they also have much more profit and thus room to negotiate with them as well.

Do you need a taper compensation head?

Taper compensation is one of the biggest misnomers in waterjet machines. Will, it functions! Of course, by leaning the jet stream before entering the material, the slightly tapered portion of the waterjet edge can be converted into the scrap material exiting a straight edge on the surface. Moreover, this identity can be accomplished by slowing the cutting speed, which also improves the surface finish and is very likely a desirable quality, and eliminates a very pricey and heavily maintained option. 

In consideration to make the taper compensation function precisely, the material has to be absolutely flat. Moreover, you have to make a tricky secondary motion system around the cutting head enabling lean, rotation, and lift as well as a surface probing system to perfectly gauge the material surface before cutting. Hence, these added three axes count complexity to the machine design and add sensitive motion elements easily directly in the cutting zone. Damage often occurs to these Taper Compensating heads from material tip-ups or inadvertent operator errors rendering costly downtime and expensive repairs likely when you least need it. Also, components are often damaged by the operating condition inherent to the waterjet. Over time it is not uncommon to see Frozen Probes and Axis overload errors due to the corrosion and build-up of abrasive waste material.

What about these Ultra High-Pressure Pump Systems are they Worth it

Over the years, the automation of these machines (i.e., a water jet tile cutting machine and a water jet glass cutting machine) techniques has significantly enhanced a lot like others. Driven by new engineering, new materials, and years of testing, pump pressure now improves the 100KPSI mark. While these ultra-high pressures deliver a considerable growth in cutting speed like anything else, they do so at a cost. At first, the cost of these ultra-high-pressure pumps can be significantly higher, 50-100% or more. Second, the components required to apply high pressure to the cutting head must be of much higher quality and as such, cost more. Finally, the maintenance needed is much more frequent as components wear out or fail without warning in a fraction of the time at these very high pressure.

Intangible world applications, we see many users dial these ultra-high pressure pumps back to manageable pressures in the 60-70K range, in general, to hinder premature impairment to internal components and to increase bolt life. Since we have noticed these pumps being operated in the same manner as the 60KPSI unit, it is clear that users are sold on the Ultra-High Pressure without considering all factors. While pressure does increase speed, so does horsepower and the more HP you can throw at the nozzle in abrasive applications, the better performance you’ll get in terms of cut speed, performance, and components longevity.
