Foam Cutting with Oscillating Knife on KMSYSTEM CNC Machines
KMSYSTEM integrates high-frequency oscillating knives into its CNC machines to deliver fast, clean, and precise cutting of PE, PU, acoustic, and technical foams. With a wide range of blades suited to different foam densities and thicknesses, our equi
KMSYSTEM designs high-performance CNC machines that are compatible with a wide range of cutting tools, including the oscillating knife, which is particularly effective for cutting foam materials.
Installed on our CNC cutting tables, the oscillating knife ensures precise, clean, and fast cutting of soft, semi-rigid, or technical foams. This technology is widely used across industries such as automotive, aerospace, insulation, packaging, and furniture manufacturing.
The oscillating knife operates using high-frequency mechanical motion, slicing through materials without crushing or deforming them. This ensures the foam's physical properties are preserved — even on sensitive materials like polyethylene (PE), polyurethane (PU), acoustic foams, or multilayer technical foams.
To meet various application needs, several blade types are available:
- Straight blades for simple, linear cuts
- Serrated blades for dense or closed-cell foams
- Long blades with up to 110 mm stroke for thick materials
- Reinforced blades for continuous high-speed production
Our machines are custom-built to match production requirements. Thanks to a rigid frame, precision linear guides, and an efficient vacuum hold-down system, stability is guaranteed even on large-scale parts.
Tool installation and replacement are quick and easy, allowing seamless transitions between different blade types. Compatibility with various market-leading oscillating tools ensures smooth integration into existing workflows and optimizes production efficiency.
