Cleaning and Re-Greasing a Rotary Polishing Machine / Angle Grinder

Cleaning and Re-Greasing a Rotary Polishing Machine / Angle Grinder Proper maintenance is the key to extending the life and efficiency of your rotary polishing machine or angle grinder. With regular use, dust, polishing residue, and fine metal or paint particles accumulate inside the housing and bearings. Over time, the grease that keeps the gears running smoothly can dry out, harden, or get contaminated, leading to increased noise, overheating, and unnecessary wear. Cleaning and re-greasing not only restores smooth operation but also ensures maximum torque, longer tool life, and safer performance. Step 1: Preparation • Disconnect the machine from the power supply (unplug it if corded, remove the battery if cordless). • Allow the tool to cool completely if it was recently in use. • Gather the necessary items: a screwdriver set, soft brushes, lint-free cloths, mild degreaser or solvent, high-temperature machine grease (suitable for angle grinders/polishers), and protective gloves. Step 2: External Cleaning • Wipe down the outer body of the machine using a clean cloth to remove dust, polishing compounds, and grime. • Use a soft brush or compressed air to clear ventilation slots and the cooling fan area. Keeping the vents clean prevents overheating and ensures proper airflow during operation. Step 3: Disassembly • Carefully remove the protective cover and access screws to open the gear housing. • Take note of the gear arrangement and parts positioning; taking a photo with your phone before removing anything is highly recommended. • Gently lift out the main gear components without forcing them. Step 4: Old Grease & Debris Removal • Scrape out old, dried, or dirty grease using a plastic scraper or cloth. • Clean the gears, bearings, and housing with a mild degreaser or solvent. Avoid harsh chemicals that may damage seals or plastic components. • Wipe thoroughly with a lint-free cloth and allow all parts to dry completely. Step 5: Re-Greasing • Apply a thin, even layer of high-temperature, high-load bearing grease specifically designed for power tools. Avoid over-packing, as too much grease can cause excess drag, overheating, or leakage. • Ensure the gears are well coated but not smothered. Rotate them gently by hand to distribute the grease evenly. Step 6: Reassembly • Refit the gears and housing components carefully in the exact order they were removed. • Secure all screws tightly but avoid over-torquing to prevent damage. • Check that the spindle lock and switch operate smoothly. Step 7: Final Inspection & Test Run • Before powering up, wipe down the machine once more to ensure no grease or residue is left on the exterior. • Run the tool at low speed for a few seconds to let the grease settle into the gears. Listen for unusual sounds and feel for smooth operation. • If everything runs quietly and smoothly, the maintenance is complete. ⸻ 🔧 Maintenance Tip: It’s recommended to clean and re-grease your rotary polishing machine or angle grinder after every 50–60 hours of intensive use, or sooner if you notice abnormal noise, reduced performance, or overheating. Regular care not only prolongs tool life but also improves polishing/grinding consistency and reduces downtime.
