Horizontal Slide Mills Dual Safety Guard

Description

Description of the MST-FR10 Milling Machine Safety Guard

The MST-FR10 protects operators from direct contact with the horizontal shaft/spindle and rotating parts accessible from both sides of the machine (front segregation of dangerous areas is excluded), and helps contain shavings and coolant. The assembly anchors horizontally to both sides of the slide.

Axial and radial shield adjustments let you position the screens quickly to prevent interference with the equipment in use. The system is electrically interlocked with a dual safety microswitch.

Advantages of the MST-FR10

• Two mirrored shields protect both sides of the horizontal shaft and slide
• Fast axial/radial adjustments for quick setups and frequent changeovers
• Side-mounted on the slide to minimize interference with machining
• High visibility of the work area
• Robust construction for industrial environments
• Dual interlock prevents start-up when the guard is open or mis-positioned

Main Components (refer to numbered diagram)

1. Adjustable angular stirrups, for microswitch box anchorage and support of the horizontal arm - in pressed steel
2. Safety microswitch main box - 180° rotation - n.2 NC contacts - electrically interlocked
3. Horizontal shield support arm - in tubular stainless steel
4. Fixing clamps for the axial and radial adjustment of the shield - in aluminum
5. Shield in plastic shockproof and oil-resistant material

About the Interlock System

The interlocked system prevents the machine from starting when the guard is open or incorrectly positioned, reducing accident risk and supporting OSHA/ANSI/ISO-EN/CE compliance.

FAQ — Frequently Asked Questions

s it suitable for frequent changeovers?

Yes. Axial and radial adjustments allow quick repositioning of the shields.

Will I keep good access to the work area?

Yes. Each shield can be adjusted to clear the work zone as needed.

Is the guard electrically interlocked?

Yes. The dual safety microswitch allows start-up only when fully closed.

What maintenance is recommended?

Regularly clean the shields and slides; check the microswitch operation and the guard’s integrity.
