Features:
High quality materials, durable, central search gauge is an auxiliary measuring tool.
Its technical index carries out enterprise standard, and is used as auxiliary tool of machine tool-Centering Indicator.
For various applications, the measuring range is 0-3mm/0.12in, equipped with measuring rods of different lengths and shapes to meet different requirements.
The centering lever indicator is used to determine the relative position between the inside and outside centers and the spindle center of the machine tool.
It has a beware of shaft rotation, and the indicator always faces the operator.
Centering indicator is a kind of precise measuring instrument, which is suitable for determining the position of workpiece component on vertical or horizontal machine tools. It can work on the worktable under the condition of motor driving or rotating the spindle of a machine by hand.
Specification:
Material: Metal
3 kinds of probe for centering indicator: 1, straight probe 2. bent probe 3. dot probe.
Measurement range: 100/4, 200/8, 300/12
Range: 0-3mm/0.12 in
Read value: 0.01mm/0.0004 in
Preparation before measurement:
1. Install the probe: screw out the fastening screw, then insert the handle of the probe into the hole on the seat, and tighten the screw to fix it. With this method, all probes can be easily replaced.
2. Install the fixing rod: There are three screw holes in the lower part of the shell of the watch. In order to make the dial face the operator and make the fixing rod easy to locate, the fixing rod can be screwed into one of the selected screw holes.
3. Install the centering indicator on the chuck of the spindle of the machine tool.
4. Install the tested workpiece on the machine tool worktable, so that the measured component can be placed in the centering table.
Spindle rotation:
1. The spindle needs to be rotated when measuring. In order to facilitate observation, the spindle should be rotated at the lowest speed or by hand. At this time, the spindle speed of the machine should not exceed 800 rpm.
2. Before the spindle rotates, the fixed rod should be blocked by a bar. Otherwise, the whole centering indicator will rotate with the machine tool together, and the indicator can not always face the operator.
Probe selection:
1. Internal circle centering: Generally, straight probe should be selected. Large probe should be selected for those with large inner diameter. When the diameter is larger than 25.4 mm (l inch), bend probe can also be used.
2. Outer circle centering: use the bent probe. Large diameter probe is selected.
3. Small hole with aperture less than 3mm/0.12 in and center of “punch mark”: dot probe can be used.
