Tools and Machines Used in Houston Machine Shop

There are many kinds of tools and equipments are used for rebuilding the engines.

There are various types of tools and machines are used in the Houston machine shop for rebuilding the engine. Now let us know more about the common tools and machines used. A dial caliper can be used to measure outside diameter, inside diameter, or depth. It may be metric or standard. The caliper has jaws that will fit within a bore or on the outside diameter of a component. A depth gauge provides an arm that scrolls down using a thumbwheel. Many dial calipers are accurate to .0005 in .02 mm.

Micrometer

The micrometer is used to measure component diameter or thickness. Micrometers may be accurate to .001 in or to .0001 in. Metric micrometers may be accurate to .01 mm. Newer engines typically require more precise measurement. Some micrometers offer a digital readout, but many require interpretation of the scales. The micrometer includes the frame, the spindle, the anvil, the barrel, and the thimble. One will measure pistons, cylinder bores, main and rod journals, and lifters using a micrometer. Accurate measurement requires practice and a good feel to achieve repeatability. Some micrometers use a slip gauge at the end of the thimble so one cannot overtighten the micrometer on the piece being measured. To interpret the measurement, first identify the number of lines showing on the barrel .Each line represents .025 in.; every fourth line is longer and shows an increment of .1 in. Seven lines showing would indicate a reading of .175 in.

Next read the number on the thimble as it lines up to the zero mark. The number on the thimble is a reading of thousandths of an inch. If the 17 on the thimble lines up with the zero line this indicates .017 in. A reading of 8 would indicate .008 in. The reading on the thimble is added to the reading on the barrel. For example, .175 in. plus .017 in. equals .192 in. Finally, add the number that lines up on the vernier scale to the end of the measurement; this is in ten thousandths of an inch. A reading of .0006 in. on the vernier scale would give a total measurement of .1926 in. Different sized micrometers are available to measure varying diameters. A 0-1 in. micrometer, for example, would be used to measure lifters. A 3-4 in. micrometer is often used to measure piston diameter on light-duty gas engines. An inside micrometer may be used to measure the size of a bore or hole. On these Houston machine shop tools the measuring arms extend outward to the edge of the bore.
