NIMS TEST PRACTICE

The safest way to remove chips from a lathe or milling machine is to use a:

• An air hose or high pressure nozzle

• Glove covering operators hand

• Shop rag soaked in solvent

• Brush

Small chips left on the spindle nose of the lathe should be cleaned to avoid:

• Run out on work holding devices

• Scratches on workpiece

• Symmetry of shapes

• Faceplate alignment

Grease guns are used to insert grease into:

• Way of a lathe bed

• Zerk fitting on machine tools

• The short taper of a cam lock spindle nose

• The T-slots of a vertical mill

To lubricate the ways of a lathe, the gibs of a mill, or the cross slide of a grinder:

• Use a grease gun with lithium grease

• Use inserts of self lubricating metal

• Use lubricants found in central lubricating systems “one shots”

• Use chalk as a lubricant since it doesn’t attract dirt

If a vertical mill table is loose and has side play, the best solution to alleviate side play is to:

• Tighten the clamps that lock the table

• Tighten the tape gib adjustment

• Loosen the taper gib adjustment

• Use a Parrel clamp and angle plate to eliminate any movement

A machinist wants to find the proper type of lubrication, schedule and recommended maintenance practices for the headstock of a lathe. Where is the best source to find this information?

• Piece of work instructions and inspection plan

• FMEA (Failure mode effects analysis)

• Control plan

• Preventative maintenance schedule and machine manual

• Tooling and manufacturers engineers handbook

General maintenance information for machine tools and machine work area can be found:

• On the inspection and sampling plan

• On a general maintenance manual

• On the capability report

• In the production work instructions

Pinning refers to:

• Back filling

• Cross filling

• Loading the file with metal chips

• Draw filing unloading

Where should files be stored?

• With end mills, drills, and other cutting tools

• In a large wooden box close the the bench area

• One file 180° close to the bench area

• In a toolbox separated from each other

The best way to clean the chips out of a file is to use:

• An air gun

• Brush

• File card

• Chalk
