  • Bar feed oil is a specialized lubricant designed for automatic bar feeding systems used on CNC lathes, Swiss-type machines, and multi-spindle screw machines. It lubricates the bar stock as it travels through guide bushings and collet areas, reducing friction and preventing galling or surface damage during the feeding process.

  • This oil is intended for use with automatic bar feeders paired with CNC turning centers, Swiss-type lathes, and multi-spindle screw machines that rely on a continuous oil bath or circulating lubrication system to coat bar stock as it feeds.

  • Bar feed oil is dispensed through the bar feeder's built-in oil reservoir or recirculating lubrication system, which continuously coats the bar stock as it advances through the feed channel and into the machine spindle. It is not a manual hand-applied lubricant.

  • A 55-gallon drum is best suited for high-volume production environments running bar feeders continuously, as it reduces the frequency of refills and typically lowers the per-gallon cost compared to pails or jugs. Shops with lower throughput may find a smaller container size more practical to avoid extended storage of opened product.

  • A full Technical Data Sheet (TDS) for TRUEGARD Bar Feed Oil is available and outlines the key performance properties, application guidance, and handling information you should review before use.
