용어는 MoTai Abrasives 기술팀이 검토 — 마지막 검토: 2026년 11월 3일.
- Aluminium oxide (Al₂O₃)
- The most common abrasive grain for belts and discs: tough, workable, suited to metal, wood and general finishing.
- ANSI grit scale
- Legacy North American grit numbering. Similar-size grains differ from the FEPA scale — name the standard in every enquiry.
- Backer pad
- The backing plate a disc sits on: pad diameter, face (hook) and port layout must match the disc.
- Backing (cloth)
- A cotton/cloth web that carries the abrasive grain on belts. Weight (e.g. X-weight) sets flexibility and load capacity.
- Backing (polycotton)
- Poly-cotton web backing: a balance of strength and flexibility for general-purpose belts.
- Belt
- A continuous loop of abrasive grain on a web backing, used on belt machines for grinding, finishing and deburring.
- Blending (weld)
- Smoothing a weld so it blends into the surrounding metal — typically a first pass on a flap disc or belt, then finer grits.
- Closed coat
- A close-coated grain layout with little open space; the belt resists clogging on harder work.
- Debur / Deburring
- Removing burrs and small protrusions left by cutting, sawing or grinding.
- Dust collection / dust extraction
- Removing abrasive dust at the workpiece — via pad ports, open-mesh discs or local extraction.
- FEPA grit scale
- The ISO 848 (FEPA) grading scale in P-notation (e.g. P120). The default scale in most European and international trade.
- Flap disc
- A disc of overlapping abrasive flaps, flexible, for grinding, blending and finishing on angle grinders.
- Grit
- The nominal grain size of an abrasive: higher numbers are finer. Belts 40–800; discs 60–5000.
- Hook & loop
- The hook-and-loop attachment system for discs: the disc snaps onto a hook-faced pad.
- Mesh / open-mesh
- Open-mesh discs have cut-out windows for dust to pass through, needing a compatible pad and extraction.
- MOQ
- Minimum order quantity — comes with the offer, alongside availability and terms.
- OEM / private label
- Original equipment manufacturing / private label: our products under your brand, labels and packaging.
- PSA (pressure-sensitive adhesive)
- Pressure-sensitive adhesive backing: the disc sticks directly onto a compatible pad.
- Sanding disc
- A flat or flapped abrasive circle mounted on a pad for sanding and finishing.
- Silicon carbide (SiC)
- Silicon carbide grain: very hard, sharp, suited to glass, ceramics and non-ferrous metals.
- Surface preparation
- Getting a surface ready for coating or finishing: removing rust, filler or old finish to a consistent profile.
- Wet / dry grade
- Grades that stay cool and clog-resistant in wet or wet/dry use; confirm suitability with the quotation.
- X-weight cloth
- A mid-weight cloth backing for general-purpose belts: strong yet flexible.
- Zirconia
- Zirconia alumina grain: tough and aggressive for metal grinding, deburring and finishing on steel.
