The inner diameter gauge is a measuring tool for measuring the diameter of the inner hole.
The inner diameter dial indicator is a combination of an internal lever measuring frame and a dial indicator. It is a measuring instrument that converts the linear displacement of the probe into the angular displacement of the pointer. It is used to measure or inspect the inner hole and deep hole diameters and their shape accuracy of parts by the comparative measurement method
INSIDE INDICATOR FOR BORING OPERATION INSTRUCTION
I: App lication indicator is applied to measurement for the diameter Of bearing shell when bor ing with arbor.
II: instruction
a. Insert the indicator into clamp tube and lock it when pointer
turns to 0.5mm on dial. Then adjust the slide to nominal dimension Of measured bore and lock it with the fizing nut
b. Zero setting on indicator according to the nominal dimension of measured bore.
c. When measuring the bore hold the tube with one hand and press slightly the supports with other hand. so that main measuring tip and support go into the bore.
Then the main measuring tip goes fro and back together with the lower measuring tip stopped in one spot, so as to find the max value within different central surfaces of arbor. The arithmetic mean is nominal dimension of measured bore.
d. The indicator must be cleaned and put in case after measuring.
III: Specifications Measuring range:
Ф48-Ф66mm (with Ф32 arbor)
Φ62-Ф100mm (with Ф45 arbor)
Trevel of main measuring tip:1.5mm Graduation of indicator:0.01mm
