Cutting machines are high-speed mechanical equipment. Proper operation and protection are prerequisites for safety. Here are the key points.
1. Operator Requirements
- Work only after passing training (Surui provides operation training)
- Know the location and use of the emergency stop button
- Understand hazard zones (blade, feed rollers, transmission)
- No loose clothing, no gloves (prevents entanglement)
- Long hair must be tied up or covered
- Never operate after drinking or when fatigued
2. Pre-Start Checks (Daily)
| Item | Standard | If Abnormal |
|---|---|---|
| E-stop button | Pops up / presses normally | Repair immediately |
| Guards | Installed, undamaged | Install before starting |
| Blades | No chipping, tight | Replace blade |
| Feed rollers | No debris, correct gap | Clean and adjust |
| Lubricant level | Within range | Top up |
| Electrical wiring | No damage or exposure | Repair immediately |
| Grounding | Reliable | Ground before starting |
3. Safety During Operation
- Never use hands on moving wire, feed rollers or blades
- Never adjust blades or clear scrap while running
- Abnormal noise / smell / vibration → press E-stop immediately
- Stop the machine before changing material (or use a safe auto-loader)
- The operator must not leave the machine while running
- Clear scrap promptly (build-up affects operation)
4. Built-in Protection (Surui Standard)
| Device | Function |
|---|---|
| Emergency stop | Cuts power instantly |
| Blade guard | Isolates the blade zone from hands |
| Feed roller guard | Prevents finger entanglement |
| Door interlock | Machine stops when door opens |
| Overload protection | Stops on excessive load |
| Earth leakage protection | Cuts power on electrical fault |
| Grounding | Prevents electric shock |
5. Personal Protective Equipment (PPE)
| Item | Requirement | Note |
|---|---|---|
| Safety glasses | Required | Against flying chips |
| Work clothes | Required (fitted) | Prevents entanglement |
| Safety shoes | Recommended | Impact protection |
| Earplugs | Recommended | Prolonged noise exposure |
| Gloves | Prohibited | Entanglement risk (cut-resistant gloves only when stopped, for blade changes) |
6. Maintenance Safety
- Lockout/tagout: cut power and hang a "Do Not Energize" tag
- Wait for full stop: 1 minute after power-off (capacitor discharge)
- Depressurize: pneumatic systems must be relieved
- Two-person rule: one maintains, one watches
- Use proper tools: never substitute hands
- Post-maintenance check: confirm tools removed and guards refitted before start
7. Handling Abnormal Situations
| Situation | Correct Action | Prohibited |
|---|---|---|
| Wire jam | E-stop → power off → remove with tool | ❌ Pull by hand while running |
| Chipped blade | Stop → power off → replace | ❌ Inspect while running |
| Abnormal noise | E-stop → investigate | ❌ Keep running to observe |
| Leakage / smoke | Power off → evacuate → repair | ❌ Touch by hand |
| Injury | E-stop → first aid → hospital → report | ❌ Deal with machine first |
8. Safety Management Recommendations
- Certified operation: operators certified after training and assessment
- Daily checklist: tick each item before start-up
- Regular training: quarterly safety training
- Emergency drills: every six months
- Incident records: log and analyze every abnormality
- Equipment ledger: record maintenance and repair history
9. Applicable Standards
- GB 5226.1 Electrical safety of machines — general technical conditions
- GB/T 15706 Safety of machinery — general principles for design
- GB 23821 Safety of machinery — safety distances to prevent hazard zones being reached
Surui machines are designed and manufactured with reference to these national standards. CE support available for export machines.
⚠️ Safety Reminder
In all cases, personal safety takes priority over production. Stop immediately when anything seems wrong — never think "just a little longer".
