发明名称 Band saw apparatus
摘要 A band saw includes a drive wheel and a fixed, curved band saw guide surface having one or more tracks for one or more band saw continuous strips. The one or more tracks contains lubricant openings which are accessed from a source of lubricant under pressure to reduce frictional resistance of the band saw moving over the guide surface.
