3. Essential Safety Regulations & Hazard Controls

DANGER — severe mechanical entanglement hazard: NO GLOVES. STRICT PROHIBITION OF GLOVES: NEVER wear gloves (cotton, leather, rubber, or nitrile), loose clothing, neckties, rings, or wrist jewelry during polishing spindle operation. The high-speed rotating spindle and cotton buff will instantly grab textile fibers and drag the operator’s hands into the arbor within milliseconds. Long hair MUST be securely bound in a protective cap.

3.1 Mandatory Personal Protective Equipment (PPE)

Eye & Face Protection: ANSI Z87.1 / EN 166 Grade B certified safety goggles or face shield.
Respiratory Protection: NIOSH N95 or EN 149 FFP2 particulate respirator for fine dust.
Hearing Protection: Industrial earplugs or earmuffs (NRR ≥ 22 dB) during extended shifts.
Apparel & Footwear: Snug workwear with elastic cuffs; steel-toe anti-slip safety shoes.

3.2 Combustible Dust & Static Grounding Protocols

Grounding: Cellulose acetate, acrylic, and polishing wax generate combustible fine dust. Ensure chassis grounding resistance is strictly < 4.0 Ω to dissipate static charge buildup.
Spark Control: NEVER polish spark-producing ferrous metals (steel/iron) without prior complete cleanout of the filtration chamber and dust drawer.

4. Installation & Pre-Commissioning

1. Leveling.

Place machine on a level concrete floor. Adjust 4 leveling footpads until the tabletop is level in all axes, then lock jam nuts.

2. Electrical.

Connect to dedicated branch circuit (16A breaker for 220V 1-Phase; 10A breaker for 380V 3-Phase). Secure PE ground wire (<4Ω).

3. Rotation.

Buffing wheel MUST rotate clockwise downward toward operator. If rotation is reversed on 3-phase units, swap incoming lines L1 and L2.

4. Wheel Mounting.

Slide inner flange onto shaft → Mount wheel → Slide outer flange → Hand-thread M16 reverse nut → Tighten firmly with spanner (45–50 N·m).

5. Standard Operating Procedures (SOP) & Finishing

Follow this streamlined 4-stage workflow to guarantee repeatable, mirror-grade finishing and ensure maximum operator safety.

5.1 Daily Startup Sequence

1. Power.

Turn ON Main Power isolator switch (green indicator illuminates).

2. Suction.

Press DUST SUCTION button and verify strong negative air draw at the hood throat.

3. Lighting.

Turn ON LED Work Light switch to illuminate the contact plane.

4. Spindle.

Press SPINDLE START and dial VFD speed potentiometer to target RPM (2,000–2,400 RPM for acetate; 3,000 RPM for metal).

5.2 Workpiece Contact Arc & Kickback Prevention

WARNING — kickback danger & safe contact zone. MANDATORY CONTACT ZONE (4:00 TO 6:00 ARC): Always present the workpiece against the LOWER QUADRANT of the wheel (between 4:00 and 6:00). NEVER polish above the centerline (12:00 to 2:00 zone) — the wheel will violently snatch and throw the workpiece forward (kickback hazard). Maintain light, steady, tangential pressure.

5.3 Eyewear & Precision Hardware 3-Stage Finishing Protocol

Process Stage	Recommended Wheel	Compound	Speed	Surface Objective
Stage 1 (Coarse Cut & Deburr)	Spiral cotton / sisal wheel	Brown Tripoli compound	2,200–2,400 RPM	Removes CNC milling tool marks and burrs.
Stage 2 (Smooth & Level)	Yellow treated cotton wheel	Green Chromium Oxide compound	2,000–2,200 RPM	Buffs frame bevels and bridge into a smooth satin finish.
Stage 3 (Mirror Finish)	Soft unstitched muslin wheel	Blue Luster or White Diamond wax	1,800–2,000 RPM	Polish with light touch for optical mirror gloss.

Compound tip — dedicated wheels per stage. Always use a dedicated buffing wheel per compound grade. A wheel contaminated with coarse Tripoli will transfer swirl marks into the final mirror stage. Rake wheels clean between batches.

5.4 End-of-Shift Shutdown Routine

Stop spindle → Run suction for 30s to purge ductwork → Turn OFF suction, light, and power → Pump dust shaker lever 6–8 times into drawer.

6. Dust Filtration, Shaker Operation & Recovery

1. Recovery Drawer — empty daily.

Turn OFF machine. Release dual quick-latches, slide 15L drawer out, empty swarf into waste/recycling bin, wipe EPDM gasket clean, and clamp latches airtight.

2. Shaker Agitation — every 4 hours.

With suction fan completely OFF, grasp external side shaker lever and pump vigorously 6–10 times. Internal grid shakes caked dust down into the drawer.

3. Swarf Recovery — precious metal reclamation.

The sealed collection drawer enables 100% dry reclamation of gold, silver, brass, and titanium polishing swarf without slurry contamination.

7. Preventive Maintenance & Troubleshooting

7.1 Preventive Maintenance Schedule

Maintenance Frequency	Mandatory Inspection & Service Procedures
Daily (Every Shift)	Empty 15L recovery drawer; clean PC visor; pump filter shaker 6–8 times; check wheel wear.
Weekly (40 Hours)	Inspect spindle arbor runout; check drive belt tension; inspect EPDM drawer gasket seal.
Monthly (160 Hours)	Inspect filter bags for tears or caking; verify ground bond (<4.0 Ω); check electrical terminals.
Semi-Annually (1,000 Hours)	Lubricate spindle bearings with 3–5g high-speed grease (Mobil Polyrex EM); check VFD.
Annually (2,000 Hours)	Replace complete set of multi-pocket filter bags (SPM-FLT-1004); inspect motor dynamic balance.

7.2 Comprehensive Troubleshooting Matrix

Fault Symptom	Probable Root Causes	Corrective Action & Resolution
Machine will not power ON	Main breaker tripped; E-Stop locked down; blown fuse.	Reset breaker; rotate E-Stop clockwise to release; check fuse.
Motor hums but will not spin	Phase loss on power line; VFD fault; arbor jam.	Verify incoming line voltages; check VFD code; clear arbor.
Excessive machine vibration	Unbalanced buffing wheel; loose M16 lock nut.	Dress or replace buffing wheel; tighten M16 nut to 45 N·m.
Weak suction airflow at hood	Filter bags caked; drawer unlatched; duct clog.	Pump shaker lever 10 times; clamp drawer tight; clear duct.
Workpiece burning (Acetate)	RPM too high; excessive pressure; dry buffing wheel.	Reduce speed to 2,000–2,400 RPM; use light touch; apply wax.
Swirl marks / haze on surface	Wheel contaminated with coarse compound/grit.	Rake wheel clean; use dedicated buffing wheel per compound.
Acoustic squeal / grinding noise	Dry spindle bearings; loose drive belt rubbing frame.	Grease bearings with Mobil Polyrex EM; adjust belt tension.
