Automatic ultrasonic cake slab cutter
The RSC-200 is an automatic slab cutting machine with an ultrasonic blade, designed and built in our Berwick workshop in Melbourne. A robot carries the blade, so it cuts sticky, layered and brittle products cleanly, in squares, bars, diamonds, wedges or any pattern you can draw. It suits industrial bakeries, confectioners and commercial kitchens that cut slabs, tray bakes and cakes by hand today.
The machine can be used standalone, or built into a production line with automated infeed and outfeed conveyors. It is also available with an optional loading and unloading work table.
What the RSC-200 cuts
- Slabs and tray bakes
- Layered and iced cakes, including whole round cakes
- Pastries, tarts and quiches
- Chocolate and confectionery slabs
- Indian sweets such as barfi
- Soft cheese wheels
Why an ultrasonic cake cutter
The blade vibrates at ultrasonic frequency, so it passes through the product instead of pressing down on it. Layers stay in place, icing and toppings don’t drag, and sticky products don’t build up on the knife. That means cleaner cuts, more even portions, less waste and less cleaning than a standard knife or a guillotine cake cutting machine. A standard blade is also available where the product doesn’t need ultrasonic cutting.
Any cutting pattern
Because a robot moves the blade, the cutting pattern is set in the program rather than by fixed tooling. The same machine can cut a slab into squares for one product and diamonds or bars for the next.
Cakes, cheese and round products
The RSC-200 isn’t only for slabs. In trials we cut whole iced sponge and chocolate cakes, and wheels of soft cheese, into even wedges. The blade went through icing, sponge and soft rind without crushing them or dragging the topping. Round products up to 400 mm across can be cut into wedges, or any other pattern.
Case study: from hand cutting to robotic cutting
A small sweets maker in Australia cut every tray of barfi by hand. With the RSC-200 the cuts are cleaner and more accurate, output is up and the team spends fewer hours cutting in the festival rush. Read the case study.

Slab cutter questions
What is an ultrasonic cake cutter?
A cutting machine whose blade vibrates many thousands of times a second. The vibration lets the blade slide through soft, sticky or layered food without squashing it or picking it up, so each cut is clean.
What size slabs and cakes can it cut?
Rectangular slabs up to 400 × 700 mm and round products up to 400 mm across, at up to 100 cuts per minute.
Can it cut more than one product?
Yes. Each product gets its own cutting program, so changing product or pattern doesn’t need new tooling.
Is it made in Australia?
Yes. The RSC-200 is designed and built by Centreline in Melbourne, and our team installs and supports it.
Can we trial our product?
Yes. Tell us about your product and the cuts you need, and talk to us about a cutting trial.
