Aluminum Oxide Polishing Film Tape for Micro Motor Polishing
Aluminum Oxide Lapping Film Polishing Tape is specifically engineered for high-precision surface finishing of micro motor components, such as stators, rotors, shafts, and housings. It features micron-graded Aluminum Oxide (Al₂O₃) abrasive particles uniformly coated on a flexible, high-tensile polyester film. This tape delivers consistent, repeatable surface quality, low scratch depth, and excellent flatness—making it ideal for micro motor polishing applications where precision and durability are critical.
Abrasive Material: Aluminum Oxide (Al₂O₃)
Backing: PET (Polyester Film), 75μm standard
Grit Sizes (Micron): 1μm, 3μm, 6μm, 9μm, 12μm, 15μm, 30μm
Format: Polishing Tape/Roll (width: 5mm–350mm, length: customizable)
Adhesive Option: Available with or without PSA (Pressure-Sensitive Adhesive)
Color: Typically tan, white, or light brown (based on grit)
Bond Type: Precision-coated for uniform abrasion
Micro Motor Shaft Surface Polishing
Rotor and Stator Component Smoothing
Surface Finishing of Miniature Bearings
Electrical Contact Area Polishing
Automated and Manual Reel-to-Reel Polishing Systems
Brushless Motor Precision Surface Preparation
Consistent Polishing Pressure: Flexible film conforms to small, complex geometries
Fine Surface Finish: Delivers low Ra surface roughness with minimal subsurface damage
High Durability: Withstands extended polishing cycles under high-speed rotation
Stable Film Width & Thickness: Ensures dimensional accuracy in reel-based systems
Clean Cutting Action: Suitable for both wet and dry polishing environments
For Micro Motor Shafts or Rotors:
Start with 15μm or 12μm grit for rough polishing
Progress to 6μm → 3μm for surface refinement
Finish with 1μm for ultra-smooth surface (Ra ≤ 0.05μm)
This sequence ensures removal of burrs, scratches, and micro-cracks while enhancing performance and reducing friction during motor rotation.
Non-aggressive cut: Safer for soft alloys like aluminum, copper, or brass
Clean finish: Prevents over-polishing or edge rounding
Low heat generation: Reduces thermal stress on micro motor components
Economical & Effective: Long-lasting, easy to integrate into reel-polishing systems
Specially formulated for micro motor & miniature component polishing
High-quality Aluminum Oxide coating ensures smooth, scratch-free results
Compatible with both manual stations and automatic reel-to-reel systems
Available in custom widths, lengths, and OEM branding
Fast delivery with strong global support and technical assistance
