More Information |
blade micrometer |
Blade micrometer is a measuring device that has a thin blade to reach inside narrow recesses. |
|
|
combination set |
Combination set is used as a rule, a square, a miter, a depth gage, a height gage, and a level. |
|
The combination set consists of: blade, center head, protractor head, combination square head, scribe, and spirit level. |
comparator |
Comparator graphically displays and measures dimensions and shapes that would be difficult to measure with regular tools. |
|
Optical measurement is a different and valuable aid to quality control. Capable of magnifying an object hundreds of times. |
depth micrometer |
Depth micrometer measures depth of holes, slots, and other recesses. |
|
|
dial indicators |
Dial indicators check alignment of machine components; show the variation of the object being measured. There are 2 types of dial indicators: |
|
|
disc micrometer |
Disc micrometer measures forming tools, cutting edges, narrow slots. |
|
|
gage block set |
Gage block set is also known as "Jo Blocks". Precision-round square or rectangular blocks are made of steel, chrome, or tungsten carbide. |
|
Gage blocks are used for: |
micrometer |
Micrometer is used to measure materials. It is available in metric and inch systems. The most common are the outside and inside micrometers. |
|
|
outside caliper |
Outside caliper measures an outside surface. |
|
Rules are also used for transfer measurements with calipers. It is used for semi-precision and comparison measurement. They depend on "feel" to measure a part. |
plug gage |
A type of "Go" or "No-Go" gage used to admit or refuse the inside dimension of an object. |
|
They are mounted at the ends of an aluminum handle. "Go" in one end and "No-Go" on the opposite end. |
ring gage |
A type of "Go" or "No-Go" gage used to admit or refuse the outside dimension being checked. |
|
There are three types: |
screw thread micrometer |
The 60 degree comparator micrometer is usually called a screw thread comparator micrometer or pitch micrometer. |
|
|
sine bar |
Sine bar is used for checking angles, typically used with gage blocks. |
|
The sine bar is a precision bar that has been hardened and then ground and lapped to very precise dimensions. It is also used for machine setups. |
snap gage |
Snap gage gages diameters, lengths,and thickness. |
|
Various types of snap gages: |
square |
A square has two straight edges that form a right angle. |
|
A machinist uses several types of squares for a variety of jobs. A square is used for inspecting squarness and laying out work. |
surface gage |
Surface gage is a scribing tool that draws lines parallel to a surface. When combined with test indicator, flatness, parallelism and heights may be inspected. |
|
Surface gages are designed for a variety of uses. The main uses are for scribing lines, transferring measurements and for probing surfaces in inspection work. |
universal bevel protractor |
Universal bevel protractor is used to lay out, measure, or check angles. |
|
|
Vernier caliper |
Vernier caliper is a precision measuring tool capable to read within .001 inch. Used for inside, outside and depth measurements. |
|
A Vernier caliper consists of a beam with a fixed measuring jaw, a sliding jaw witht he Vernier scale, and a mechanism for making fine adjustments. |
Vernier gear-tooth caliper |
Vernier gear-tooth caliper measures gear teeth using two Vernier scales. |
|
|
Vernier height gage |
It is rugged and reliable tool that gives precise and dependable measurements over long vertical ranges. It is also used for precision layout. |
