Blake Manufacturing is the original inventor and creator of this unique Co-Ax Centering indicator device that easily locates the center of your work piece. Most machinists know Blake as the Premier Brand for this type of CoAx Centering Indicator.
The BLAKE CO-AX INDICATOR provides a simplified method for centering a workpiece or fixture on HORIZONTAL or VERTICAL machines, EXTERNAL or INTERNAL diameters and also with N/C, EDM and other hard-to-turn spindles.
The face of the indicator remains stationary in any desired position while the machine spindle rotates, thus leaving the operator with both hands free to accurately position the machine table by coordinated movement of the table positioning controls while observing the indicator hand reaction. (Indicator hand travel diminishes as location error is reduced to a point where the hand stands still, indicating coaxial alignment of the diameter being checked with the spindle axis)
By using the CO-AX INDICATOR with the machine spindle running, exact operating conditions are more nearly simulated for the centering operation since the influence of power transmission, lubricant flow, bearing characteristics and torque are integrated into the indicator reading.
