Take lighter cuts or in feed at slower rate. Use coarser or softer wheel.

Check slides on truing attachment; they may be worn low in centre. Do not change angle of housing. Increase traverse or in feed rate to make wheel act softer.

Troubleshooting Tips: Centerless Grinding

Insufficient passes on hardened work. Use crowned cam when dressing grinding wheel. Do not dress wheel or change angle of truing attachment.


Dress with sharp diamond at increased traverse rate. Pull up evenly on alternate bolts before cinching up. Use coarser grain size and softer grade. Wheel too soft—use harder grade. This gives maximum straightening effect on grinder.

Loose or tight regulating wheel grknding will cause periodic or intermittent flats on work piece.

When through-feed grinding relatively short work, without using a loading device, do not use fingers to push work between wheels.

Flush guards and wheel after each truing. Work too trobleshooting above centre. Inspect spindle and collet—remove burrs if present. Slide adjusting screw thrust bearings loose. Loose regulating wheel spindle bearings. When a problem occurs while grinding, finding the cause is not easy due to the variety of complexly intertwined factors involved. True edge of blade. Uneven fine lines on work piece due to faulty dressing Do not allow diamond to dwell on wheel. Reset diamond or use new one.

Stock removal too slow when in feed grinding.

Keep flange screws tight at all times. Motor bearing defective or armature out of balance.


Remove or change spacer behind regulating wheel so side of regulating wheel is back of grinding wheel. Move spiral gear on screw to new contact face and lap gears together. Prevent work jamming into wheel. Always balance wheel in following sequence: Use a coarser grained wheel with more open bond to allow greater chip clearance. Wheel should be just a nice sliding fit Maximum clearance of 0. First pass should be a light cut with high spindle housing angle but slow regulating wheel speed.
