Maintenance tips for guideways and oil pockets

The guideways of the worktable and machine bed of a surface grinding machine are subject to a certain amount of wear over time. To maintain the precision of the machine in the long term, the following maintenance measures should be carried out:

1. Scraping the contact surfaces

The contact surfaces of the guideways are scraped to ensure uniform contact. The contact accuracy should be more than 12 points per 25 mm², with a scraping depth between 0.006 and 0.01 mm.

2. Uniform guideway clearance and flatness

The guideway clearance between the worktable and the bed guideway must be uniform. The flatness error of the table guideway should not exceed 0.01 to 0.02 mm – i.e. less than the hydrodynamic lifting of the table during operation.

3. Overhaul of the oil pockets

The oil pockets on the guideway surface of the worktable are scraped to maintain their depth. This improves the oil flow and ensures optimum lubrication of the guideways – the basis for a smooth, uniform table movement.

Conclusion: Regular inspection and professional maintenance of the guideways pays off: higher grinding accuracy, smoother table travel and a significantly longer service life for your machine.
