Turcite B for Surface and Cylindrical Grinder Ways
Grinders are the machines where guideway quality is most visible in the finished part, because the table has to travel smoothly at very low feed while the wheel removes microns. A Turcite B liner on the table and wheelhead ways removes the friction step that shows up as a ripple in the ground surface.
Why grinders are the hardest test for a way
A surface grinder table crosses the wheel at a feed rate measured in millimetres per minute, and the wheelhead infeed is measured in microns. At those speeds the slide spends all its time in the transition between static and dynamic friction — exactly the region where a worn metal way wants to move in steps.
That is why a grinder with tired ways leaves a regular ripple on the work: the table surges, the wheel cuts deeper, the table stalls, the cut shallows. Relining narrows the friction gap and the ripple disappears without touching the wheel or the spindle.
Contamination is the main wear driver
Grinding produces fine abrasive swarf that is far more damaging to a way than machining chips. It embeds in the liner, acts as a lapping compound, and wears both the strip and the mating way. Wipers, way covers and clean coolant are not optional on a grinder — they are what decides whether a reline lasts two years or ten.
When a grinder is stripped for relining, the wiper condition should be checked before anything is reassembled. A hardened, grit-loaded wiper will damage the new liner within weeks, and it is far cheaper to replace at that point than to reline again.
Matching the liner to the counterface finish
A liner runs best against a finely finished, straight counterface. If the way has been ground or scraped to a good finish, the liner beds in quickly and holds a stable contact pattern. If the counterface is rough or has been left with a directional grind pattern, the liner wears faster and the running-in period is longer.
Running-in is normal and expected: a new liner polishes into its counterface over the first hours of use. What is not normal is continued wear after that period — that points to contamination, overload or a counterface that was never finished properly.

Frequently asked questions
- Can a surface grinder table be relined in place?
- It is sometimes done on small machines, but the table is normally removed so the ways can be cleaned, checked and machined first. Working in place makes it very hard to clamp the strip evenly and almost impossible to machine the finished face flat.
- Why does my grinder still leave a ripple after relining?
- Check the wheel balance, spindle bearings and the lubrication circuit before blaming the liner. A reline removes friction-induced ripple; vibration from an unbalanced wheel or a starved oil pump produces a similar mark and is unaffected by the way material.
- Which grade suits a grinder?
- Brown or brick red grades are commonly used on grinder rebuilds, and the choice is usually driven by what the rebuild shop already stocks and how the face will be finished. All grades share the same PTFE base and the same thickness range.
