Machines Mfg Since 8 09 4 T SB1024 8B1025 SB1026 Cleaning Regular cleaning is one of the most important steps in taking good care of this lathe Each operator is responsible for cleaning the machine immediately 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 it may drive them deeper into moving surfaces and could cause sharp chips to fly into your face or hands All visible swarf should be removed from the mill during cleaning Remember personal neatness gives you personality Unpainted amp Machined Surfaces Besides the ways and elevation leadscrew all other unpainted and machined surfaces should be wiped down daily to keep them rust free and in top condition This includes surface you can find that could be vulnerable to rust if left unprotected this especially includes any parts that may be exposed to water soluble cutting fluids Typically with these parts a thin film of oil is all that is necessary for protection South Bend Lathe Co Lubrication The mill has numerous moving metal to metal
