Description: |
| Claim:
The present invention relates in general to machine tool ways and more particularly to such ways of the general type provided with bonded nonmetallic wear plates and disclosed in United States Patent No.2,675,276, issued 13 April, 1954, to Jesse Daugherty.
In machine tools of the type having movable members supported and guided in their movements by means of complementary, elongated ways provided on the movable members and their respective supports, it is advantageous to provide relatively soft wear plates attached to one of each pair of complementary ways for sliding engagement with the hard bearing surface on the co-acting way. It has been found that such relatively soft wear plates are most desirably formed of materials having advantages as regards non-scoring and other physical characteristics not possessed by metal plates. Such materials include certain plastics, one widely used material for this purpose being a laminated fabric impregnated with the plastic material known in the trade as "Formica." |
