CMM Machine Bellow

About CMM Machine Bellow

• Materials: Typically made from thin, high-tensile materials such as polyurethane-coated polyester (approx. 0.16mm thickness) or nylon fabric. Some industrial variants use rubber, PVC-coated fabric, or even stainless steel.
• Shapes: Common configurations include C-Type (most popular for rails), rectangular, round, and square.
• Construction: Often manufactured using thermal welding or high-frequency (HF) welding to ensure they are leak-proof and durable.
• Temperature Resistance: Standard bellows typically withstand temperatures from -10C to 70C, though specialized versions can handle up to 500C for high-heat environments. 

1. Contamination Protection: Acts as a barrier against fine dust, mist, and metal shavings that can wear down bearings or cause measurement errors.
2. Accuracy Maintenance: By facilitating smooth thermal expansion and contraction, bellows help the machine maintain its calibrated precision despite temperature fluctuations.
3. Extended Lifespan: Protects internal drive systems and sensors, reducing maintenance costs and downtime. 

• Drag & Friction: High-precision machines require "minimal drag" bellows to ensure the probe movement remains ultra-smooth.
• Axis Travel: Bellows must be custom-tailored to the specific X, Y, or Z-axis travel distance to prevent over-extension.
• Retrofitting: Many bellows are designed to be easily removable or retrofitted onto existing equipment without major disassembly
