Abrasive Wheels
Course Content
This training course is designed to provide participants with the essential knowledge, skills, and attitude required to safely and effectively use abrasive wheels in various applications. Participants will learn about different types of wheels, their uses, and potential hazards, as well as proper mounting, operation, and maintenance techniques. . By the end of the course, attendees will be equipped to handle abrasive wheels confidently and competently
Course Agenda
Recognize common hazards of abrasive wheels (bursting, kickback, entanglement, flying particles, noise, vibration, and dust) and how they cause injuries.
Identify wheel types & markings (bonded vs. coated, bench/pedestal vs. handheld, cutting vs. grinding) and read labels for size, specification, and maximum operating speed (RPM).
Match wheel to task & machine: ensure the wheel’s speed rating ≥ machine spindle speed, compatibility with material, and that flanges, blotters, and mounts are correct for that wheel.
Perform pre-use inspections: check for cracks/damage, expiry, storage damage, and ring-test appropriate vitrified wheels before mounting; remove any suspect wheel from service.
Mount wheels correctly: only trained/authorized persons fit wheels; isolate power, clean spindle/flanges, use blotters as required, tighten to specified torque, and run up the wheel in a safe area before use.
Set up guards & rests: ensure guards are present and correctly positioned; tool rests and tongue guards adjusted to proper gaps; never operate with missing or defeated guards.
Use required PPE for the task (eye/face protection, suitable gloves where appropriate, hearing protection, respiratory protection for dust, protective clothing) and control sparks and dust (screens, extraction).
Operate safely: maintain stable stance and grip, avoid side-loading unless wheel is designed for it, do not force the cut, allow wheel to reach full speed, keep bystanders clear, and manage hot work risks.
Dress and true wheels when needed to remove glazing and restore geometry; only with the correct dresser and procedures, and re-check guards/rests afterward.
Follow training, supervision, and reporting rules: work within authorization, stop and report defects or incidents immediately, and apply lock-out/tag-out during maintenance or wheel changes.
