Cleaning &
Protecting
Regular cleaning is one of the most important steps in taking good care of this mill. Each opera- tor is responsible for cleaning the machine imme- diately after using it or at the end of the day. We recommend that the cleaning routine be planned into the workflow schedule, so that adequate time is set aside to do the job right.
Typically, the easiest way to clean swarf from the ways and table is to use a wet/dry shop vacuum that is dedicated for this purpose only. The small chips leftover after vacuuming can be wiped up with a slightly oiled rag. Avoid using compressed air to blow off chips, as this may drive them deep- er into moving surfaces and could cause sharp chips to fly into your face or hands.
Besides the ways and elevation leadscrew, all other unpainted and machined surfaces should be wiped down daily to keep them
