The surfaces of longitudinal table ways are all hand scraped to getting perfect contact pattern
and to ensure very high accuracy.
Longitudinal table ways are designed to have slide surfaces longer than that of the working surface and equal to the table length to keep the table free from torsion and deflection(except PSGS series).
PROTH is a leading surface grinding manufacturer for more than 30 years in Taiwan.
We have developed and pioneered a whole line of surface grinders including the small saddle type, the medium column, large double column type and rotary type which have been widely acclaimed by domesfic and oversea users.
We also developed vertical grinding machines for I.D., O.D. and end-face for your workpieces.
