Dustshoe (suction) for 80mm HF-Spindle (CNC) - NEW: V2!

thingiverse

Edit 28.11.2019: I have again improved the suction system based on my own experience (V2): - Three-part construction - allows printing without support structures - upper part is screwed to middle part with four countersunk screws M4x10. - Circumferential edge at middle part - prevents lower part from shifting under any circumstances. - Magnets on both sides of the system - provide stronger holding power for lower part (be sure to pay attention to polarity when gluing magnets). - Double-breasted apron in lower part: I first applied a strip of 0.5mm soft PVC, then cut it at suitable intervals (around 12-15 mm), and finally glued another strip on top with the cuts offset from the first layer's sections - resulting in a very dense yet flexible and transparent apron. For my CNC milling machine with a 1.5 kW HF spindle (air-cooled), I have designed a suction system that features: - Lower part easily removable (magnet holder). - Lighting within the suction system (LED strip). The upper part is directly attached to the flange of the HF spindle using a fitting hose clamp. Inside the upper part are six neodymium magnets (8x2mm) glued in place. Within the middle section, there's a 10mm wide heel where you can attach matching LED tape (waterproof). The cable is guided through a hole to be mounted in the upper part and exits to the outside. In the lower part, there are also six neodymium magnets (8x2mm) used for attachment to the upper part. I have used transparent PVC (0.5mm thick) as an apron and stuck it on with superglue (check the edit above). I've printed the lower part multiple times and covered it with aprons of different lengths - allowing you to put on the matching lower part depending on the length of your milling cutter. To build this suction system, you'll need: - Hose clamp (around 70mm) - Twelve neodymium magnets (8x2mm) - Four countersunk screws M4x10 - Soft, transparent PVC (0.5 mm thick) - LED strip light (I used the one found here: https://www.ebay.de/itm/DC12V-5M-5054-SMD-LED-strip-light-strip-bar-band-light-wire-warm-white-DE/174043998975?ssPageName=STRK_MEDESCO&var=&_trksid=p2057872.m2749.l2649) I've added the CAD drawing as a .step file for your adaptation to an existing spindle. Have fun building!
