What are the materials of the machine tool shield

The materials used for machine tool guards vary widely to meet the needs of different machines and processing environments. Below are common guard materials and their characteristics:

1. Metal Materials
   (1) Steel Plates & Stainless Steel:
   The most common metal guard materials. Typically formed from 1.5mm–4mm thick cold-rolled steel or stainless steel sheets using cutting/press brakes. Advantages include high strength, heat resistance, and mechanical durability, making them suitable for large machines and high-speed equipment. Drawbacks include heavy weight, high cost, rust susceptibility, and frequent maintenance needs.

   (2) Aluminum Alloy:
   Lightweight, corrosion-resistant, and moderately strong, ideal for weight-sensitive applications.

2. Plastic Materials
   Offer corrosion resistance, easy processing, lightweight, and lower cost. Suitable for small machines and low-speed operations. Limitations include poor heat resistance and mechanical durability, making them unfit for prolonged high-speed machining.

3. Nylon-PVC Composite
   Often used in bellows-type guards: Nylon fabric exterior with internal PVC reinforcement. Combines oil/corrosion resistance, impact resilience, compact compression, and long travel distances, making it adaptable to complex environments.

4. Silicone-Rubber Composite Fabric
   Excels in oil/acid/alkali/heat resistance, suited for specialized high-demand environments.

5. Three-Proof Fabric (Nylon Fiber)
   Waterproof, dustproof, and oil-resistant. Commonly used in roller-type guards for balanced protection and cost efficiency.
