Ceramic fiber is a lightweight, high-temperature insulation material with advantages such as high-temperature resistance, low thermal conductivity, chemical resistance, and excellent insulation properties. It is widely used in metallurgy, chemical engineering, aerospace, building insulation, and automotive exhaust systems.

If you've ever handled insulating materials like rock wool, glass wool, or ceramic fiber, you know they're not to be trifled with. They can sting your skin, blow fibers everywhere, and turn your workshop into a dusty battlefield.

To address these challenges, the AOL CNC vibrating knife cutting machine has become a vital piece of equipment for processing ceramic fiber products.

First, understand this type of material：

Rockwool: Dense, fireproof, and strong. Commonly used in walls and ceilings.

Glasswool: Lightweight, flexible, and soft. Used for sound and thermal insulation.

Ceramic fiber: Resistant to high temperatures, often exceeding 1200°C. Ideal for furnaces and fireproofing.

CNC vibrating blade cutting machines use a high-speed reciprocating blade instead of traditional knives.

Controlled by a CNC system, the blade vibrates up and down at high speeds, reaching a frequency of tens of thousands of times per minute. This mechanical cutting principle, rather than thermal cutting, allows for cold cutting of ceramic fibers.

Different insulation materials require different settings. Here are my recommendations:

Rockwool (20-100 mm): Use a high-amplitude pneumatic vibrating tool. This provides good density control.

Glasswool (20-50 mm): Use a pneumatic vibrating tool with medium amplitude. Always use vacuum to prevent shifting.

Ceramic fiber (20-50 mm): Use a pneumatic vibrating tool with a bevel cutting tool. This is ideal for V-grooving and sharp cuts.

Preparation for cutting ceramic fiber:

Material Securement

Place the ceramic fiberboard or ceramic fiber blanket flat on the workbench and activate the vacuum function to secure the material securely, preventing movement or warping during cutting with the vibrating blade.

Drawing Import and Layout

Use intelligent layout software to import CAD drawings and perform automatic or manual layout to improve material utilization.

Select the appropriate tool and parameters

Tool type: We recommend using a straight or circular vibrating blade, suitable for flexible ceramic fibers.

Cutting depth: Adjust the tool's cut depth based on the material thickness (typically 10-50 mm).

Cutting speed: Generally 500-1500 mm/s, fine-tuning based on density and thickness.

Oscillating frequency: Adjust to 8,000-12,000 vibrations/minute to ensure a smooth cut without tearing the edges.

Dust collection and safety precautions

Ceramic fiber cutting generates fine dust. A dust collection system should be activated or a dust cover installed. Operators are recommended to wear a dust mask and goggles.

Cutting process and key technical points：

Start the machine

Turn on the CNC cutting system. After confirming that the program path, tool origin, and parameter settings are correct, start a test cut.

Automatic Identification and Path Optimization

The machine automatically identifies cutting lines and internal and external contours, and uses a path optimization algorithm to reduce idle motion and improve efficiency.

Multi-layer Cutting Technology (if required)

For stacked ceramic fiber materials, layered cutting mode can be enabled. The tool automatically cuts in steps, ensuring clean, tear-free edges between layers.

Automatic Material Rewinding

After cutting, an automatic material rewinding system or suction platform allows for integrated processing and improved production continuity.

Using a CNC vibrating knife cutter to cut ceramic fibers not only effectively improves processing precision and production efficiency, but also significantly enhances the working environment and material utilization.

For companies producing high-temperature insulation materials, this type of equipment has become an ideal alternative to traditional manual and die-cutting methods, enabling intelligent and clean production.
