How do you align shafts with a dial indicator?
How do you align shafts with a dial indicator?
For shaft alignment, we typically use dial indicators with 0.250″ – 0.300” total travel. The plunger moves a needle clockwise when pushed in and counter clockwise when let out. The face can be rotated so that the needle points to zero.
What is the dial indicator used for?
The dial indicator is used to indicate the run-out (the misalignment between the workpiece’s axis of rotational symmetry and the axis of rotation of the spindle) of the workpiece, with the ultimate aim of reducing it to a suitably small range using small chuck jaw adjustments.
How do you adjust dial indicator?
Rotate the face of the indicator until the “0” marking aligns with the dial. Tighten the knob afterward to lock the face in position. Twist the zero adjustment knob if your dial indicator does not feature a rotating face. Continue twisting the knob until the dial aligns with the “0” marking.
How do I reset my dial indicator?
How do you calibrate a dial indicator?
To calibrate you need a gauge stand, a surface plate, and appropriately sized gage blocks. The dial indicator is mounted on a gage stand on the surface plate, a zero is set on the dial, then gage blocks are inserted, and dial indicator reading is taken to determine that it is functioning properly.

How do you zero a dial indicator?
How do you adjust a dial indicator?
Raise the plunger and slip a 0.020-inch gauge block underneath. Lower the plunger onto the surface of the gauge block. Check that the indicator reads 0.020-inch. Raise and lower the plunger two more times to check that the dial indicator gives the same measurement in the same spot repeatedly.
How are dial indicators used for shaft alignment?
For shaft alignment, we typically use dial indicators with 0.250″ – 0.300” total travel. The plunger moves a needle clockwise when pushed in and counter clockwise when let out. The face can be rotated so that the needle points to zero. The case is held by a clamp and holding rod which are, in turn, held by a jig or magnetic base.
What are the primary parts of a dial indicator?
The primary parts of a dial indicator are the face or dial, the case, and the plunger. The plunger is a spring loaded part that can be depressed into the case causing the dial to move clockwise. Dial Indicator […] Alignment Knowledge All you ever wanted to know about shaft alignment Home Alignment intro Why do we align? When do we align?
Is there a procedure for reverse dial indicator alignment?
The procedure for doing reverse dial indicator alignment is not a difficult one. There are several steps which need to be taken for a successful alignment job. Familiarize with terms, techniques and procedure. Learn about the machine you are aligning. Visually check coupling, pipehangers, base bolts, coupling spacing etc.
What should I do if my dial indicator needle moves?
Retighten bolt and make sure the dial indicator needle does not move. Repeat this procedure for the remaining feet. The vertical move is the part of the alignment process that aligns the two shaft’s centerlines into their proper up and down position. Usually you will have to add or remove shims in this step.
