MAINLAND STONEWORKS

charts a NEW COURSE using robotics Mainland Stoneworks isn’t afraid to try something new. After charting a new course to survive the crash of the housing market in 2006, the business is again reinventing itself through the latest robotic automation technology available for the stone industry.

It can finish a job within 15-18 minutes. The cutting speed is paying dividends for the shop.


A Robo SawJet can cut a standard 40-squarefoot kitchen countertop with sink hole from a slab in half the time of other machines. “Our installers are more productive,” Bertelsman said. “The capacity of our shop doubled. Overtime went away. It allowed us to go back and sell. We were turning down work.” BACA Systems also offers its own Vein Match software, allowing shops to match veins from different parts of the same slab, preventing waste. “Vein matching and the nesting of parts being cut on the slab really increases our yield,” Bertelsman said. Mainland technicians were still resorting to the use of paper templates in the field before the company transitioned to the Robo SawJet. Now it runs a completely digital operation. “With laser templating, we’re much more accurate with our measurements,” Bertelsman said. “We do all of our cutout design in shop now. It saves us money and time.”

Material Savings The BACA RoboSawJet’s IDE Diamond Cutting Head offers consistent alignment. The accuracy of the Robo SawJet allows customers to save an average of 25 percent on material cost annually.

What it does is allow us to keep up with our schedule. The accuracy means work that once had to be done in the field stays in the shop, Bertelsman said. “Our biggest customers are cafeterias. One big cafeteria countertop area might have 60 different holes being cut out. We used to have to drill and cut all those in the field. One of the nicest changes is we can now cut it to match in the shop, and it works perfectly. It saves a tremendous amount of time during installation.” Mainland depends on the Robo SawJet for consistent production. “What it does is allow us to keep up with our schedule,” he said. “Right now, we’re doing about 500 square feet per day. We’re more constrained by the back end of our shop and the installation, not the cutting.”

It’s very, very easy to use and user-friendly. The Robo SawJet’s simple, intuitive PC-based operating software is designed to lower barriers to use by employees. Instead of having to depend on one or two experienced operators, other workers can step in to run the machine as needed. “It’s very, very easy to use and user-friendly,” Bertelsman said. “It can be programmed in the office or at the machine. You have flexibility. You’re not depending on just one person to do it all.”

They have great customer service with their responsiveness and interest in helping us with issues that come up.

Maintenance and Customer Service The KUKA robot itself is practically indestructible, needing almost no maintenance for 10,000 hours or five years. The Robo SawJet uses a durable H2O jet pump, designed to last under grueling 24-hour per day automotive manufacturing conditions.

The pump, which can last up to three times longer between rebuilds than Hypertherm pumps, costs less than half to operate than the KMT pumps used in other brands of sawjets. If there are problems encountered during the operation of Robo Sawjet, BACA technicians can remotely log on to the onboard computer to diagnose the problems. “They have great customer service with their responsiveness and interest in helping us with issues that come up,” Bertelsman said.

Future Plans In 2016, Mainland opened a state-of-the-art 45,000 -square-foot natural stone and solid surface fabrication facility in Winston Salem, North Carolina, to expand its reach into the eastern U.S. Bertelsman said he is considering purchasing a Robo SawJet for the next facility. Meanwhile, Mainland continues to depend on the Robo SawJet to drive production at its Texas plant. “We’ve been really happy it,” Bertelsman said. “It changed the way we do business.”

We’ve been really happy with it. It changed the way we do business.
