High precision HLTNC CNC tool length sensor
For my new CNC build I needed an affordable, easy to use and accurate cnc tool touch probe to do automatic tool length measurement.
I chose for HLTNC’s option due to the fast shipping to EU and good prices. I opted for the “with dust blow” model as it allows me to keep the touch probe clean when doing automatic tool length measurement with my uccnc controller.
Items were packed well, arrived in ~14 days from China to EU and was complete and to spec. I paid ~45 USD for it including shipping and taxes.
Physical product – tool length setter
THe body is made by anodized cnc milled or turned aluminium. Which is free of dents, scratches and burrs.
The wiring is protected by a metal sleeve which covers he rubber wiring.
The bottom features a serial number which could indicate that there is individual quality checks and potentially even calibration done on the tool length sensor.
The tool length plunger/plate features a rubber or silicone gasket which keeps chips and coolant out of the internal workings and mechanics of the tool length setter.
Instructions of the touch probe
The instructions themself that are affixed to the box it came in are in chinese.
Product Description:
The repeat positioning accuracy of this product can reach 0.01mm, and the layered sealing design is completely anti-drop, anti-collision, and dust-proof.wiring is simple, easy to install and use.
Suitable for all kinds of engraving machines.
Additionally it tells you how to connect the probe in case of a DC24V PNP or 0V NPN setup.
