For automotive and machining applications, a tool known as a dial caliper is frequently employed as a precise tool that is fairly simple to use. It is capable of measuring parts down to the thousandth. It is user-friendly and measures parts to the thousandth. Look into growwithsupplychain web site if you need details information all about dial caliper.
It's much easier to show how to use dial calipers, rather than write it down and then read it. This guide will teach you how to utilize dial calipers.
Utilize A Dial Caliper Step By Step Guide
Step 1
Outside jaws
Bezel nut
Lock nut
Dial indicator
Inside Jaws
Shut down the caliber. Check the jaws. If you can see no light, the caliper is shut completely. If you're able to see light coming through the jaws of the caliper the caliper should be thoroughly cleaned. A metal burr may hinder the caliper from closing properly.
Step 2
Close the clamp. Then take the bezel nuts off. Once it's loose, rotate the outer of the dial until the needle on the dial is directly over zero. Now , tighten the bezelnut.
Important Note Be absolutely sure that the measurement area is clean and free of dust as any debris can greatly affect the precision of the measurement.
Step 3
The type of component being measured, you'll be able to measure from the outside or the inside of the jaw. Width, length and thickness are measured with the jaw's outside. Gaps and holes are measured using the jaw's inside.
Step Four
To measure a part (we will use the jaw's outside just like when we measure length, width, or thickness) it is first necessary to move the jaw. Put the item in the jaw. The jaw should be closed around the piece, making sure there is an unrestricted feel. At the same time with no complications, the piece should be able to slide out and in of the jaw fairly easily. After that, put the lock screw in place on the caliper. This will hold the position.
Step 5
To make a precise determination of the measurement It is essential to be familiar with what the dial marks. Every 10 marks equals (2.5 cm) 1 in, so every mark would equal.1 or.10 in. The number upon which the needle rests, on the indicator on the dial, needs to be expressed in thousands ofths. That means any number you see must be multiplied with.001. For example. When the needle is resting on 15 (between 10-20) the number displayed by the dial is 0.0.015 inches. But this is only part of the measurement.
Step Six
This is the remainder of your measurement. Straight edges are situated to the left side of the dial indicator. What is the length of inches that the straight edge passed? Then, figure out how many tenths of the straight edge has gone by. Write both of these down. Example: 1.3 inches. Then, you can see on the dial the number which is just below the needle. Multiply the number by .001. Also record that number. Like the example from step five, we will say that this number will be 0.015 inches. Combine all of these numbers.
Step Seven
You now have your measurement! The measurement of the piece in our case is 1.315 inches.
A caliper is just one of the many instruments utilized in metrology. Incredibly, there is far more than just one type of caliper as well. Many makes and models are readily available, each having their own specific characteristics, model number, series number and so on.
