A centering indicator, also known as a coaxial indicator, is a precision measuring tool used to accurately determine the center of a workpiece. It is commonly used in machining and manufacturing processes to ensure precise alignment of parts.
- For quick and accurate centering in boring and milling set-up
- Jeweled bearing
- Supplied with 7 type feelers
How it works:
A centering indicator consists of a mainbody with a dial indicator mounted at a right angle. As the workpiece rotates,the indicator measures the deviation from the center. By adjusting the workpieceuntil the indicator reads zero at all positions, the center is accuratelydetermined.
Applications
- Milling Operations: Used to ensure that a workpiece isproperly centered on the milling machine's table, relative to the spindle,before machining begins.
- Lathe Operations: Ensures that a cylindrical workpieceis aligned with the lathe's spindle axis for accurate turning, facing, andother operations.
- Quality Control: Employed in inspection processes toverify the concentricity and alignment of machined parts.
- Tool Setup: Helps in setting up cutting tools andfixtures by ensuring they are precisely aligned with the machine's spindle.
This measuring tool has other names too. Wiggler Machining Center-Finder, Coaxial Indicator or Centering Indicator
    Advantages of a Centering Indicator
	- High Precision: Provides accurate and reliable 
	measurements, crucial for ensuring the quality and precision of machined 
	parts.
- Time-Saving: Reduces setup time by allowing quick and 
	easy alignment of workpieces, improving overall efficiency in the machining 
	process.
- Versatility: Suitable for a wide range of applications 
	in different machining operations, making it an essential tool in any 
	machine shop.
- Durability: Designed to withstand harsh shop 
	conditions, ensuring long-term reliability and performance.
In summary, a centering indicator is an indispensable tool for machinists and 
engineers who require precise alignment of workpieces with machine spindles. Its 
high sensitivity, ease of use, and durability make it a valuable addition to any 
machining operation, ensuring that components are accurately centered and ready 
for precision work.
