CNC Shark Touch Probe Figure 3 - Power Strip On/Off Switch CNC Shark. The gantry (with the probe sitting at the level of the collet nut or so), DeskCNC probe. IMService is a master distributor of DeskCNC. We are seeking new OEM's and dealers. DeskCNC Windows based CAM SOFTWARE and a powerful CNC MACHINE CONTROL. DeskCNC is also a family of related products for powerful desktop machining. Built in probe scanning routines for surface scanning to cad file.

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.

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.

202033P - 1/4' diameter shank, Touch Trigger Probe TP-100 w/6' shielded cable, no connector. This TP-100 contact probe is a 1/4 inch diameter shank, 5 way ( +X,-X,+Y,-Y,-Z) mechanical contact scanning device with a 2mm (.0787 in) diameter ruby tip. It is used with CNC milling and CNC routing style machines to digitize surface and contour data. When used as a probe the shank is mounted in a spindle collet or chuck or other holder parallel to the spindle axis. Tip stylus extensions are available in 20, 30, 60, and 90 mm lengths. 1mm, 3mm, and 4mm diameter, ruby tips styli are also available. Features: • Interchangeable CMM Ruby Tipped Stylus - Ruby is one of the hardest materials known.

A ruby tip is unlikely to degrade due to abrasive material scanning. The ruby stylus on this probe has a sphericity ( roundness) of.000050,( 50 millionths) of an inch. • Hardened Tool Steel alloy Shank. Precision mounting with accurate repeatability Black Oxide treated to prevent rust.

• Small body design, permits maximum vertical scanning range for small desktop machines ( only 1 inch diameter ( 25.4 mm) x 7/8 inch long( 22.2 mm)) This probe will work with CNC controllers that interface to a probing input from a switched contact.

For other CNC systems, please check with the producer to verify that the system can utilize a contact probe When used with DeskCNC, a probed surface is filtered, smoothed, reverse compensated for the probe tip radius, and saved as an.STL CAD file. The 3D surface machining CAM in DeskCNC can make minor edits to the surface and will produce 3D surfacing toolpaths to duplicate the scanned part.
