More Information

blade micrometer

Blade micrometer is a measuring device that has a thin blade to reach inside narrow recesses.

Image of blade micrometer
The blade micrometer measures narrow grooves and keyways.

Image of blade micrometer
Bract micrometer is used for measuring where the standard micrometer spindle could not be accommodated.

combination set

Combination prepare is used as a rule, a square, a miter, a depth cuff, a height gage, and a level.

Image of combination set
Combination set

The combination set up consists of: blade, centre caput, protractor caput, 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.

Also known as shadow graph

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.

These micrometers come as a set with interchangeable rods to accommodate various measurements.

dial indicators

Punch indicators check alignment of machine components; show the variation of the object being measured. There are 2 types of punch indicators:
a. Counterbalanced reading (has figures in both directions from the zero)
b. Continuous reading (numbered continuously)

Image of dial indicator
Dial indicators tin can exist used to make linear measurements.

disc micrometer

Disc micrometer measures forming tools, cutting edges, narrow slots.

Image of disc micrometer
The disc micrometer is besides chosen a flange micrometer.

This micrometer finds its application in measuring flanges and hard to reach areas.

gage block set

Cuff cake set is as well known as "Jo Blocks". Precision-round square or rectangular blocks are made of steel, chrome, or tungsten carbide.

Image of gage block set
The measuring surfaces are lapped and polished to 200 milionths of an inch.

Gage blocks are used for:
- calibration and inspection of precision instruments
- to set comparators/indicators
- setting of sine bars
- precision layout
- machine setups

micrometer

Micrometer is used to measure materials. It is bachelor in metric and inch systems. The most mutual are the exterior and inside micrometers.

Available in dissimilar shapes and sizes

outside caliper

Outside caliper measures an outside surface.

Image of outside caliper
The exterior caliper is used to measure outside bore.

Rules are too used for transfer measurements with calipers. It is used for semi-precision and comparison measurement. They depend on "feel" to measure a office.

plug gage

A type of "Become" or "No-Become" gage used to admit or decline the inside dimension of an object.
There are iii types:
- plain cylindrical
- cylindrical taper
- thread plug gage

Image of different plug gages
Available in different sizes

They are mounted at the ends of an aluminum handle. "Become" in i end and "No-Go" on the reverse terminate.

ring gage

A type of "Go" or "No-Get" gage used to admit or refuse the exterior dimension beingness checked.

Image of ring gage
Band gages are used as sets.

There are three types:
- patently ring gages
- taper ring gages
- thread band gages

screw thread micrometer

The 60 degree comparator micrometer is unremarkably called a screw thread comparator micrometer or pitch micrometer.

The pitch bore, the well-nigh important measurement of a spiral thread.

sine bar

Sine bar is used for checking angles, typically used with gage blocks.

Image of sine bar
Precise angles are measured using the sine bar.

The sine bar is a precision bar that has been hardened and and then footing and lapped to very precise dimensions. It is also used for automobile setups.

snap gage

Snap gage gages diameters, lengths,and thickness.

Image of snap gage
The adjustable limit snap cuff is used to bank check exterior diameter.

Various types of snap gages:
- adjustable snap gage
- adjustable gyre snap gage
- punch indicator snap gage

square

A square has two direct edges that form a right bending.

A primary precision square

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 examination indicator, flatness, parallelism and heights may exist inspected.

Image of surface gage
The surface gage

Surface gages are designed for a variety of uses. The main uses are for scribing lines, transferring measurements and for probing surfaces in inspection piece of work.

universal bevel protractor

Universal bevel protractor is used to lay out, measure, or bank check angles.

Image of universal bevel protractor
The bevel protractor can mensurate angles to five minutes of a caste.

Vernier caliper

Vernier caliper is a precision measuring tool capable to read within .001 inch. Used for inside, outside and depth measurements.

Image of Vernier caliper
The Vernier caliper

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-molar caliper measures gear teeth using two Vernier scales.
