Application Recommendations for MX Machinery Disc Brushes

MX machinery disc brushes are designed for specific industrial applications that require precision and consistency. Here are some key recommendations for using MX machinery disc brushes:

Recommended Infeed

• The optimal infeed for a disc brush with bristles right to the edge lies between 0.8 mm and 1.5 mm. Higher values do not necessarily increase metal removal and can lead to faster wear of the brush.
• Recommended Speed for Nylon Bristles: The speed should allow the greatest number of bristles to contact the workpiece. The recommended range is between 1,000 rpm and 2,300 rpm, which is significantly below the maximum speed.
• Feed Rate Optimization: The feed rate determines the cycle time and should be optimized individually. Start with a lower feed rate and gradually increase it if the burr is successfully removed.
• Overlap: The ideal overhang beyond the workpiece is approximately 35 mm on each side.
• Direction of Rotation: The direction of rotation should be the opposite of the cutting tool to enhance the brushing effect and remove the burr more effectively.
• Wear Limit: The wear limit is reached when the remaining length of the bristles is no longer sufficient to ensure the flexibility of the bristles. The bristles then no longer wrap themselves around the edge.
• Travel: The travel of the brush should be set so that on approach and retraction, the full circumference of the brush projects beyond the workpiece. This ensures all edges are processed.

Standard Mounting

• MX machinery disc brushes can be combined with all indexable face mill mountings and combination face mill adapters.
• No further accessories are required for mounting.
• Positive force transmission ensures consistent performance.

Dynamic Pad Form

• High concentricity and maximum resistance to tipping.
• Recesses for reduced weight and improved handling.

Bristle Design

• Bristles are solidly cast in place, ensuring they do not break off even at high speeds.
• Special versions with individual densities of abrasive grit are available for specific applications.

High-Tech Bristles

• Nylon bristles are impregnated with abrasive grit.
• Temperature-resistant up to 160C (320F).
• Chemical resistance permits use of coolants for enhanced performance.
