Stone fabrication machines and brands: bridge saws, sawjets, CNC routers, waterjets and edge polishers

A countertop shop cuts slabs with a bridge saw, shapes cutouts and edges with a CNC router, and often adds an edge polisher, a waterjet or a sawjet (a saw and waterjet on one machine). Most shops buy a bridge saw first, a CNC router second and a waterjet or sawjet third. As rough 2026 U.S. ranges (makers rarely publish prices), new CNC bridge saws cost about $80,000 to $200,000, production routers $120,000 to $250,000, and sawjets $200,000 to $450,000 or more. Well-known makers include Park Industries, BACA Systems and Northwood Machine in the U.S., Breton, Intermac, Donatoni, GMM (part of Italy's Biesse Group since 2024), Prussiani and CMS Brembana in Italy, and Flow and OMAX in waterjets. Choose on local service, controller and software compatibility, and fit with your work, not on brochure accuracy figures.

The machines and what each one does

Each machine is good at one kind of cut. A shop's machine list is really a plan for which cuts happen where.

How each machine is run is covered in bridge saws and sawjets, CNC machining and waterjet cutting. Polishing is in polishing and finishing.

Which machine to buy first

Most shops grow their equipment in the same order, because each step removes the biggest bottleneck at the time.

1. Bridge saw. It does most of the linear cutting on every job. Many startups begin with a used manual saw and hand tools, and profile edges by hand.

2. CNC bridge saw or 5-axis saw. Once volume or remakes hurt, a saw that reads the digital template takes skill out of each cut. A 5-axis saw makes sense when mitered and waterfall work is weekly.

3. CNC router. Takes over cutouts and edge profiles from hand grinders. A shop that owns a router usually keeps a saw too, because a router doing straight cuts ties up the machine with work a saw does several times faster.

4. Edge polisher. Adds straight-edge capacity and frees the router for cutouts and curves.

5. Waterjet or sawjet. When porcelain, sintered stone, inlays or complex cutouts are a steady part of the work, or when replacing the saw anyway.

As a rule of thumb, shops below about 8 to 10 kitchens a week often do better buying a used saw and outsourcing CNC or waterjet work to a larger shop or regional cutting service than carrying a machine they can't keep busy. See equipment planning.

What the machines cost

Makers rarely publish list prices, so these are rough new-price ranges used across this knowledge base, not quotes or maker figures:

Price moves with table size, axis count, tool changer size, automation (cameras, part stackers, rotating tables), controller and software packages, and for imported machines, freight and import duties. As a rule of thumb, used machines often sell for 40 to 60% of new.

The machine is not the whole bill. Budget for:

• Site work. 3-phase power, a level reinforced floor that can carry a machine and slab weighing several tons, water supply, drains and a slurry or water-recycling system. As a rule of thumb, installation and facility prep add $10,000 to $40,000 or more. See shop layout and facility and water recycling and slurry.

• Tooling. Blades, core bits, profile wheels and polishing pads. As a rule of thumb, a busy router alone spends $10,000 to $30,000 a year.

• Software. CAM software to program the machine, if it isn't included, and training for the programmer.

• Maintenance. A common rule of thumb is 3 to 5% of the purchase price per year, not counting tooling.

A worked example: what a CNC saw costs per month

A shop finances a $180,000 5-axis saw over five years at 8% interest.

• Loan payment: about $3,650 a month.

• Maintenance at 3 to 5% of price a year: about $450 to $750 a month.

• Total: about $4,100 to $4,400 a month before blades, power and operator wages.

At 20 kitchens a month, that is roughly $205 to $220 per kitchen for the machine alone. At 40 kitchens it halves. That is why volume, not the machine's spec sheet, decides whether a CNC pays. Model it with your own job count, labor rate and remake history, not a dealer's payback example.

The major makers

Many brands sell into U.S. countertop shops. The ones below are well established. This is a map of who makes what, not a ranking, and product lines change, so check each maker's current lineup.

U.S. makers

• Park Industries (St. Cloud, Minnesota; family-owned; founded in 1953). Started out building stone splitters and now makes CNC saws, sawjets (such as the SABERjet and JAVELIN lines), CNC routers (such as the TITAN) and edge polishers for stone. Park says it has installed more than 500 SABERjet sawjets.

• BACA Systems (Orion Township, Michigan). Best known for robotic sawjets, in which a saw blade and waterjet are carried on an industrial robot arm rather than a gantry (its Robo SawJet line, currently the M Series 240). Its lineup also includes a 5-axis saw, CNC routers and edge polishers.

• Northwood Machine (Louisville, Kentucky; founded in 1988). Makes CNC routers, a stone FabCenter and a sawjet for stone, along with machines for wood, composites and aerospace work.

Italian makers

• Breton (Castello di Godego, Italy; founded in 1963; privately held). A large stone-technology group. It developed the Bretonstone process that many engineered quartz makers use under license to produce their slabs, and it builds CNC work centers (Contourbreton), bridge saws, sawjets (Combicut) and edge polishers.

• Intermac (Biesse Group, Pesaro, Italy). The stone and glass machinery brand of Biesse, with U.S. sales and service through Biesse America. Makes CNC machining centers (the Master series), saws and Primus waterjets.

• GMM (Italy). Maker of bridge saws, 5-axis saws and CNC machines. Biesse Group completed its purchase of GMM's holding company on January 29, 2024, and since May 12, 2025, GMM's U.S. business has been part of Biesse America. Biesse now markets the former GMM machines in its own stone range.

• Donatoni, Prussiani and Achilli. Italian makers of bridge saws, 5-axis saws and CNC machines, sold in the U.S. through importers and dealers.

• CMS Brembana (CMS Stone Technology, part of Italy's SCM Group). CNC work centers and waterjets.

• Comandulli and Marmo Meccanica. Italian makers best known for inline edge polishers.

Waterjet makers

• Flow International (Kent, Washington; founded in 1974; part of Shape Technologies Group). Early developer of ultra-high-pressure waterjet cutting, with pumps rated up to 94,000 psi.

• OMAX (Kent, Washington; part of Hypertherm Associates since 2019). Abrasive waterjets sold with the maker's own programming software.

• Other waterjet brands sold to stone shops include WARDJet and KMT, which is best known for high-pressure pumps, and several machine makers offer waterjets or sawjets of their own.

Italian makers have a long record in stone and offer a wide choice of heavy, highly automated equipment. U.S. makers point to domestic parts stock and shorter service trips. Both points matter less than what the dealer and technicians in your region can actually do. A great machine two days from the nearest technician can be a worse buy than a good one with a technician an hour away.

How to compare brands

Brochure accuracy figures (a few hundredths of a millimeter one way or another) won't show in a finished kitchen, where the template and the stone set the fit. Compare what affects your uptime and your workflow.

1. Service in your region. Where is the nearest technician? What is the response time in writing? Which parts are stocked in the U.S.? Is there a loaner or remote diagnostics?

2. Controller. Some machines run widely used industrial controllers from large automation makers, others run the maker's own. An industry-standard controller can make service, operators and third-party software easier to find, and matters more on a used machine as it ages.

3. Software chain. Which CAM software programs it, and is there a tested post processor, the translator that turns CAM toolpaths into that controller's code? Does it read your templating device's DXF directly? See the next section.

4. Fit to your work. Table size for your largest slabs (jumbo slabs run about 65 by 130 inches). Axis count for the miters and profiles you actually sell. Tool changer size for the number of profiles you run.

5. Training. What installation training includes (often a few days on site), and what it costs to train a second operator later.

6. Site requirements. Power, water, floor load, footprint with loading space and ceiling height for cranes.

7. Operators. Whether trained operators for that brand are available in your area.

8. Resale and parts life. How long the maker supports older models and controllers.

Ask the dealer for three shops near you running the same machine, and call them. Ask about the last breakdown and how long it took to fix.

Compatibility: making the file chain work

A CNC is only as useful as the file that reaches it. The usual chain runs: templating device, drawing or CAD, slab layout, CAM programming, post processor, machine controller. See DXF and CNC files.

Things that break it:

• Post processors. Each CAM package needs a post processor for each machine and controller. Confirm it exists, is maintained, and is included in the price.

• DXF versions. Some older controllers read only older DXF versions and need a conversion step.

• Units and layers. A DXF has no built-in units, so a millimeter file read as inches comes in about 25 times too large. Agree on units and layer names once.

• Proprietary formats. Some machines and templating devices work best with their own file formats and lose data through DXF.

• Controller upgrades. Older machines may need a controller or software upgrade to accept modern files.

Before you buy, send the dealer real DXF files from your templating device and your drawing software, and watch them cut a test piece on the same model you will buy. See digital templating tools.

Buying used

A used machine can halve the price, and bridge saws in particular are mechanically long-lived. Most of the risk is in the electronics and the support.

• Controller and software. Is the controller still supported? Can the software license be transferred, and at what cost? A 15-year-old proprietary controller can be the end of an otherwise sound machine.

• Mechanics. Check rails for straightness and wear, ball screw backlash, spindle runout with a dial indicator, and the vacuum and water systems.

• Waterjet pumps. Ask for pump hours and rebuild records. An untracked intensifier pump can need an expensive rebuild soon after purchase.

• Moving it. As a rule of thumb, rigging, transport, reinstallation and recalibration can cost $10,000 to $30,000.

• Inspection. Pay a qualified technician to inspect it before purchase, and budget for a factory service visit after installation.

Common mistakes

• Buying a machine sized for a hoped-for volume, then financing an idle machine.

• Choosing on price or spec sheet without checking service coverage in your region.

• Assuming your CAM software or templating device works with the machine without testing a real file.

• Underbudgeting the site: power, water recycling and floor.

• Training one operator. When they leave, the machine sits.

• Skipping maintenance in the busy season, which is when downtime costs most.

• Buying a sawjet or 5-axis machine for work the shop does only a few times a month.

Where software helps

A CNC is usually the shop's most expensive and most scheduled asset, and a surprise down day or a double-booked week backs up every install. In Stonify, a machine can be an assignee on tasks like a person, so cutting, routing and polishing tasks created from the job's workflow show on the production calendar per machine. The calendar totals square footage and hours booked per day, so the scheduler sees each machine's load before adding work. Days can be blocked on a machine for blade changes, spindle service or calibration, so the scheduler sees that the machine is out. On the countertop drawing, each sink and cooktop cutout is drawn in its real shape with center lines and distances from the edges, so the programmer sees where each opening sits.

FAQ

Is Park Industries better than Breton or Intermac? None is better across the board. Park is a U.S. maker with domestic support. Breton and Intermac offer wide ranges of highly automated Italian machines. The right choice depends on your work, your budget and the service available where you are.

Do I need a 5-axis saw? Only if you cut miters, waterfalls or bevels every week. A 3-axis CNC saw plus a router handles most residential work.

Can a CNC router replace a bridge saw? It can cut everything, but slowly on straight lines. A router-only shop gives up capacity, so most shops with a router also run a saw.

What is the difference between a sawjet and a robotic sawjet? Both combine a saw blade and a waterjet. A standard sawjet carries them on a bridge gantry. A robotic sawjet mounts them on an industrial robot arm, which allows more automation and part handling, at a higher price.

How long do stone machines last? As a rule of thumb, the mechanical frame of a well-maintained saw or router lasts 15 to 20 years or more, and controllers and electronics often need upgrading after about 10 to 15 years.

Should I lease or buy? Both are common. Compare the total paid over the term, what happens at the end, and whether maintenance is included. Ask your accountant about depreciation and Section 179 expensing, which change the after-tax cost.
