What is the back jaw?
100
This part of the lathe should be used to hold the drill when making concentric holes.
What is the tailstock?
100
This one-directional cutter can be used to chamfer metal parts.
What is a file?
100
This machine should be used to achieve high precision in the hole location when drilling.
What is the mill?
100
All tools must spin in this direction, regardless of speed or gear range.
What is a clockwise?
200
These are used to keep a workpiece near the top of the vise in the mill.
What are Parallels?
200
This general guideline tells you how far away from the fixture you can turn your work in terms of the diameter of the workpiece.
What is the 3:1 Rule?
200
First perfected by Anne Crepin in France, this tool can rough out shapes from stock but does not provide a high surface finish.
What is the band saw?
200
This strong adhesive should not be used instead of fasteners as it does not allow for rework and can be brittle.
What is epoxy?
200
This tool should always be used to a depth just below the end of the taper.
What is a center drill?
300
This part of the mill should be used to move a tool in the vertical “z” direction, instead of moving the entire bed.
What is the quill?
300
Left in, this tool can cause serious damage when the lathe is turned on.
What is the chuck key?
300
Improper wiring can often lead to this problem with motors on the RMP, causing emergency brake stopping.
What is shorting?
300
This drill size is needed for putting a 1/4-20 bolt through a piece of Delrin.
What is 17/64"?
300
This tool should be run at 100 RPM and is used to create holes for press fitting bushings.
What is a reamer?
400
These type of end mills are preferred when machining high-carbon steel or stainless steel due to high temperature resistance and hardness.
What is Carbide tooling?
400
This tool can be used to support a part, but requires center drilling the workpiece.
What is a live center?
400
These flexible parts may be used instead of a set screw to rotationally fix an axle.
What is a spring pin?
400
This tool can make almost any shape out of metal, but should not be used to create holes with any precision.
What is the waterjet?
400
The center to center accuracy for these holes should be +/- 0.001”
What is reamed?
500
This precisely machined accessory allows for accurately locating the center of round parts on the mill.
What is a Collet Block?
500
Grooves can contribute to a high level of this and add significant additional resistance in bushings.
What is surface roughness?
500
Not to be confused with edge-blown aerophones, end mills may have any number of these.
What are flutes?
500
This tool should be used to check tolerances of +/- 0.005”.
What is a micrometer?
500
These 0.0890" tools frequently break due to lack of reversing direction and lubricant.
What are 4-40 taps?
