What is dial gauge

Gauge head uses cogwheel to spin around, then utilize the movement
of pointer to present measuring result's comparison measuring instrument.

What's comparison measuring instrument

Unlike the direct measuring value reading of varnier caliper and micro
meter ,which needs to be compared with other standards to get the
reading value and measuring error.
Comparison measuring instrument must have a comparison standard.

Standardize methods of using

Usually not to use alone, should be used with holding device to
hold on stem. Most of the base is magnetic base, measuring
error will occur while using stem and arm, however, it will have
accurate measurement by looking at measuring variation.
It's a very convenient tool to use.
In the working place, we need direct measuring
value reading and measuring of parallelism, flatness,
and core degree. Dial gauge would be the
most convenient tool to use.

Using example

Fine adjustment device
if the megnetic base is with fine adjustment device,
it would easy to set on.

Types of Dial gauge

Standard type

Gauge head and spindle can be moved up and down.

Lever type

Use the principle of leverage to expand the move of gauge head, it's
also called dial indicator. The gauge head is small and the angle can
be changed freely, it's convenient for small space measurement.

Long stroke type

Long dial gauge with wider measuring area.

Examples of using Dial gauge

		Holdng position Dial gauge can not be correctly used only from fixing the jig. When measuring flat surface, make sure spindle (gauge head) is perpendicularto the surface. When measuring the outside of the cylinder, spindle should be perpendicular with the axis of cylinder.
01 Usedial gauge to measure cylinder foundness of lathe processing.	02 To measure concave and convex of end surface.

Examples of using Dial indicator


01 To measure the vise on lathe.	02-1 During process of lathe, set the workpiece on scroll chuck, then measure the deformation of cylinder surface.	02-2 To measure the inner core degree.
	03 Convenience of perform measurement of narrower groove surface or to make measurement that's more precise than dial gauge. The more parallel of the gauge head and measuring surface, the more it will be measured accurately. To measure the inner core degree. *Inaccuracy will occur if magneticbase doesn't have fine adjustment device or is place at a inconvenient location.	! Gauge head should be parallel with measuring surface and right angle with measuring direction.
