Abrasive Waterjets for Stone

Waterjets – or, to be specific, abrasive waterjets – may never be as ubiquitous as bridge saws in stone-fabrication shops, but they’re becoming the must-have machine for companies making their mark with custom work and close-tolerance cutting.
And, the selections are growing at a fast clip. Two years ago, anyone at a U.S. trade show might be hard-pressed to see more than three companies offering a machine to the stone industry. Now, with the first Stone Business survey of abrasive waterjets, 20 manufacturers are in the thick of the market fight.
The stone industry is also making an impact on the machines themselves; abrasive waterjets continue to grow in production area and the ability to handle larger pieces – i.e., stone slabs – in a continuous-production process. Several companies now offer models designed exclusively for stone.
It’s also a field where a few manufacturers are producing combination machines, marrying waterjet and basic saw capabilities.
Information in this survey includes the machine’s production area and the accuracy of initial and repeated cutting (or piercing) of stone. While the latter numbers seem close to microscopic – measured in the thousandths of inches – such close tolerance is key for medallions, insets and other intricate work.
Worktable dimensions are included to show the surface area that can hold a piece of stone. Where possible, there’s also the maximum weight that’s supported by the worktable.
Models can change, and prices of European-made machines can vary with the exchange rate between U.S. dollars and the euro. For the latest information – and before making any purchase commitment – always contact manufacturers or the U.S. agents/distributors.
The information provided is from surveys distributed to manufacturers in October 2006, along with additional research by Stone Business staff. Metric dimensions converted by Stone Business staff.
