Cleaning Machines



Cleaning the shop machines is one of the most important rules of the shop. Not only does it increase the longevity of the machines, but it also creates a safer environment for everyone in the shop. See below for a quick reference guide.

Why Cleaning is Important
 Increase life of all machines


 * The cleaner the machines are the less time and money required to maintain them.

 The Quality of the Machined Parts are Maintained
 * Keeping tracks clean will prevent them from getting worn down and off center. If they are scratched up and worn down the movement of parts along the tracks will be sticky and can cause imperfections to the item being machined.

 A Cleaner Shop is a Safer Shop


 * Keeping oil off the floor will keep people from slipping and injuring themselves.
 * Metal shavings can cause splinters and cuts to the machine operators.
 * It is more comfortable to work on a clean machine, this allows the operator to focus on what they are doing and prevents them from losing fingers.

 Keeps The Shop Presentable


 * Looks good to all people invested.
 * Is a presentation point for potential investors and students.

Proper Machine Cleaning Procedure


1. Clean all tools and place back into proper locations
 * Use rag to remove grease and shavings from tools.
 * Use compressed air if necessary to dry any tools hit with coolant
 * Place all tools into their proper storage area

2. From top to bottom, use the hand broom to brush all large shavings off machine onto the floor
 * Use dustpan to catch shavings keeping them from spreading.

3. Use rag to soak up oil and coolant
 * Do not forget to wipe off things removed from machines this includes vices, fourth axis,etc... It also includes the bottom sides of these parts where the oil and coolant builds up and is never cleaned.
 * If necessary use compressed air and/or WD40 on metal parts touched by coolant.
 * Remove shavings from rag into garbage can before disposing of rag in bin.

4. Sweep up shavings off of floor
 * Make sure to get underneath the mats.

5. Vacuum all remaining shavings (on and off machine)

6. Scan 360 degrees around machine
 * Look for hidden and missed messes, move parts of machine if necessary.

Things to Avoid
 Using Compressed Air to Blow Off Machines


 * Air can force metal shavings into the track systems on machines. These shavings will scratch up and wear down the tracks.
 * Shavings blown into the air can injure machinists.
 * Lubricant can be removed from parts.

 Vacuuming Up Large Amounts of Oil


 * Large quantities of oil can plug vacuum filters.
 * Oil in the vacuum can over strain the motor.

 Using Harmful Cleaning Material


 * Rough scrubbing tools can scratch up the machines
 * Certain chemicals can remove paint or damage finish.

Commonly Missed Messes
 Behind Machines


 * Usually missed because these require more effort to clean or see.
 * Because these messes are avoided they build up and require a lot more time to clean.

 Hidden Behind or Underneath Movable Objects


 * Under and inside vices are often neglected.
 * Under the tail of the lathes rarely get cleaned.

 Single Step Machines


 * Belt sanders and grinders get used by many people and cleaned by few.
 * The drill press might only make a few smaller shavings but should still be cleaned.
