Our range

Mineral wool cutting machines

CNC wire cutting machines for 2D and 3D shapes, multi-unit machines for cutting boards to size and to bevels, and vertical band saws. Every design is matched to your material and throughput.

PPRK vertical band saw

A vertical band saw with automatic body feed, self-adjusting blade tensioning and an emergency brake. Cuts in both directions.

Why us

Engineered for your production

We do not sell machines off a catalogue page. We start from your material, format and throughput, and design the machine around them.

CNC control

Touch panel and CNC control with stored recipes. Repeatable dimensions without resetting the machine for every new job.

Dust-free wire cutting

Wire cutting does not create the mutagenic dust that abrasive cutting does. Better working conditions and lighter demands on extraction.

Boards from 5 mm

An automatic hold-down keeps the block in place while cutting, so even very thin boards can be produced.

Made in Poland

Design, machining, welding, assembly, electrics and commissioning — all under one roof in Kępno.

Many materials

Stone and glass mineral wool, PIR boards, XPS, upholstery foam — one machine, many applications.

Safety

Guarding with electric interlocks, blade-break brakes, loading outside the danger zone.

Service and parts

Full warranty and post-warranty service, fast response, spare parts in stock.

Upgrades

Extending existing machines with additional cutting units, roller tables, dust extraction or new controls.

Technology

Wire or band saw?

The right tool depends on what you cut and how. Wire cutting machines excel at shapes, angles and thin boards — the wire follows any contour and does not tear the fibres. A band saw is faster for straight cuts through thick, dense boards and for laminated materials.

  • 2D and 3D contours, bevels, roof wedges — KPA CNC wire cutting machines.
  • Cutting boards to commercial sizes — PS multi-unit machines.
  • Straight cuts through thick boards — the PPRK vertical band saw.
  • Not sure which to choose? Send us a sample and we will run a test cut.

FAQ

Frequently asked questions

We build KPA CNC wire cutting machines (including the 3D version with two rotating tables), PS horizontal and bevel machines with two or four cutting units, and PPRK vertical band saw machines. All of them are built from scratch in our own plant.

On the KPA wire cutting machine the automatic hold-down allows boards from 5 mm thick. For thinner or very soft materials it is worth running a test cut on your own wool.

Yes. Tool and parameter choice depends on density: for hard stone wool and laminated boards a band saw or circular units usually work better, while shapes and thin boards call for wire cutting. Send us a sample and we will run a test.

Yes. The machines cut stone and glass mineral wool, PIR boards, XPS and upholstery foam. One machine can serve several materials in your plant.

Yes — every parameter is set individually. We change the working width and length, cutting height, number of cutting units, type of hold-down and material feed, and we add roller tables or dust extraction as needed.

The CNC wire cutting machines run devFoam 2 software — drawings are easy to prepare, with no machine-tool programming knowledge required.

Yes. We provide full warranty and post-warranty service, fast response times and stock of wear parts: wires, saw blades, rubberised wheels and pneumatic components.
