Precision Straight Edge

Precision Straight Edge

This flatness gauge creates successful precision measurements of flat honing, lapping and polishing wheels. Higher quality requirements with respect to the flatness of workpiece measurements during a flat honing, lapping or polishing process has given the signal to design a precision straight edge. Having regular control of the wheel flatness is indispensable for the quality system. Consistently having control of the working wheel surface avoids time-consuming correctional works and increases the machining run time.

The three-dial gauges have a diameter of 58 mm. The light metal profile the gages are latching onto makes transportation almost effortless. This allows the measurement of the unevenness of 0.001 mm and more. The unit has a 3-point-rest for measurement recordings of the inner, middle and outer parts of the wheel to determine its true shape. Handling according to the manual which also includes the inspection record sheets. While creating the precision straight edge, we developed a flatness gauge that can make reading the top wheel easier without having to hold it. You simply flip it upside down balancing the legs on the bottom wheel. You then bring the head of the machine down until the wheel makes contact to receive the surface reading of the top wheel.

We manufacture and customize flatness gauge’s for any size fine grinding, lapping or polishing machines.

Dual-Probe Thickness/Flatness Gaging

Thickness Measurement Gauge
Measures the thickness and parallelism of a workpiece

The dual-probe gauge systems provide improvement of thickness measurements needed for surface grinding and lapping operations. This measurement tool uses an opposed pair of gage probes. There’s one probe above and one below the part that is secure in place for a precise measurement of a workpiece. This measuring tool also gives an accuracy of stock removal within a part. This is critical to confirm each finished workpiece in a load is even throughout to achieve parallelism expectations.

Measurement resolution can be set as fine as .000005″ (five-millionths of an inch) or .0002mm (one-fifth of a micron). Coarser resolution settings are selectable therefore, accommodating the different types of finishing demands.

The display unit offers both easy to read digital numeric readout and analog meter style display.

Monochromatic Inspection Light

The flatness of workpieces is measured with the interference tester. The lamp generates monochromatic light and thus permits the interference fringes to be seen using a precise optical flat. The distance from one so-called “light band” to the next is around 0.3 microns.
