RAIL GRINDING PROCEDURE
Before grinding, wipe the rail surface clean with a cloth saturated with mineral spirits, followed by a wipe with a clean dry cloth.
Surface contaminants such as rust, grease, oil, and water condensation will affect the integrity of a CADWELD
® bond. Discard
soiled rags and debris in an approved manner.
1. Wear proper safety equipment! Gloves made of a non-slip material, eye protection, hearing protection, hardhat,
safety shield, steel-toed boots, and other appropriate safety equipment must be used.
2. Stance: Take the proper stance in front of the area to be ground with the grinder idling. Rest right arm on knee
while in squatting position. Lift with your legs, not your back.
3. Wheel Position:
Grinding for Head Bonds Wheel must be used only at the center of the head of the rail, within the confines of
the splice plate.
Web Grinding Wheel must be used only at the neutral axis of the rail.
4. Wheel Guard Adjustment: If desired, you may adjust the orientation of the wheel guard by loosening the clamping screws
and rotating the guard to the desired position. Retighten the screws before grinding. (Note: The guard for the Type 27, cone-
shaped wheels, part no. SBG20015G, has an adjustable skirt. The skirt must be adjusted to within 1/8” of the face of the
wheel per ANSI
® B7.1-2000. The skirt or the entire guard may be removed when using the Type 18 plug wheel as ANSI B7.1-
2000 does not require a guard for Type 18 wheels of this size.)
5. Grip: Grasp the BEARING HOUSING with your left hand while gripping the CARRY HANDLE (foam handle) with your
right hand.
6. Accelerate the engine to full throttle just before wheel touches grinding surface.
7. Begin grinding with the wheel against the rail moving with a side-to-side motion until bright base metal is shown.
8. Allow wheel to do grinding for you. Exert only slight pressure to prevent loading of grinding wheel.
9. Release the THROTTLE TRIGGER as soon as the wheel loses contact with the rail, allowing the engine to idle.
Note: See instructions provided with ERICO ® frame assemblies, molds, and/or welding material for the proper procedure
for preparing and installing ERICO’s exothermic rail bonds.
