Cleaning/Protecting
Because of its importance, we recommend that
the cleaning routine be planned into the workflow
schedule.
Typically, the easiest way to clean swarf from the
machine is to use a wet/dry shop vacuum that is
dedicated for this purpose. The small chips left
over after vacuuming can be wiped up with a
slightly oiled rag. Avoid using compressed air to
blow off chips, as this may drive them deeper into
the moving surfaces or cause sharp chips to fly
into your face or hands.
All unpainted and machined surfaces should be
wiped down daily to keep them rust free and in
top condition. This includes any surface that is
vulnerable to rust if left unprotected (especially
parts that are exposed to water-soluble cutting
fluid). Use way oil to prevent corrosion (see
Page
75 for an offering from Grizzly).
