Looking for a simple inexpensive touch probe for parts measuring and hexapod calibration, during last two months I became a kind of market expert in touch probes. So, here's a summary of my investigations. There are many top-quality industrial probes with 1um and better precision, based on kinematic, optical or strain gauge technologies. The most popular industrial probes are. Renishaw RMP600 machine tool probe Renishaw PH1+TP20 CMM probe Renishaw TP1S manual CMM probe Their list prices are unacceptable for home use ($2000 and more). Used probes might be purchased on ebay for $300-$500.

TP100 Probe for Mach3, linuxCNC, EMC, Flashcut, DeskCNC or other systems Probe - TP100A Probe-Toolsetter, Adjustable shank in 1/4, 10mm, or 3/8 diameter List Price: $375.00. Batik cirebon.

Renishaw probes usually need special shanks, connectors, interfaces, receivers etc. Another option is simple industrial probes with ruby tips and near 25um precision like / touch probe ($249-$299).

The kinematic location consists of a pivotal plate 1 that is spring-loaded against three bearing points 2 by a helical compression spring 3. These bearing points are formed by a combination of rollers and ball bearings. Bearing points act as electrical contacts such that when the pivotal plate is deflected, the electrical circuit changes its characteristics and causes the probe interface to send a trigger to the CMM controller.

Following this trigger event, the stylus ball must be removed from contact with the surface to enable the probe to return the stylus ball to its repeatable position. There's newer patent illustrating the same principle ( U.S. Such homemade probes are intended to work with CNC like Mach3 or EMC2. They connect to input pins of parallel port or breakout board. Each probe is usually equipped with LED indicating its state. Main problems of homemade kinematic touch probes: • The resistance of contact between small ball and rod might be not so low, and the probe circuit includes 6 such contacts connected in series.

For better contact golden-plated balls and rods can be used, or electronic circuit to increase the input sensitivity and stabilize the current through contacts. • If the probe parts made inaccurately, its rods might not contact the balls at all 6 points simultaneously in initial position. • If balls and rods diameters and distance between balls are not chosen properly, the probe might not always go back to initial position when released, or stick between balls. • The probe tip center usually does not coincide with probe shank axis, therefore some device needed to adjust the stylus tip position.

The probe comes packaged with all devices needed for digitizing or tool setting. An instruction sheet is also included for converting between probe and tool setter along with maintenance instructions and Certificate of accuracy. DeskCNC will automatically compensate for the diameter of the probe tip and will create a true definition stl cad file for machining the reproduced part allowing you to rough and finish with different sized tools. NO NEED TO SCAN AND CUT WITH THE SAME SIZE TOOL.
