Proxxon TBM 220 Bench Drill

Les produits Proxxon sont très bon.

No se como había fabricado PCBs de forma "manual" sin este taladro de banco. Su precisión es increible, baja sin ningun juego mecánico, pude hacer perforaciones de 0.3mm sin problemas, sin quebrar brocas. Tengo un dremel con la columna vertical pero este Proxxon es mucho mejor, esta en una dimensión totalmente diferente. Tanto el taladro como los accesorios tienen un acabado mecanizado de increible precisión. Lo recomiendo mucho!

Smaller in size than I expected but still perfectly usable for my purpose (drilling PCB through-holes). Spindle and collet system run true enough to easily drill 0.3mm holes. I can't do 0.2mm or 0.25mm reliably but then I haven't bolted down the machine for extra stability like they recommend. Also I'm holding the workpiece freehand rather than clamping it down securely. In any case, this drill machine beats a dremel rotary tool mounted in their $50 drill stand by a large margin. Initially there was problem with the machine when I opened it to change the belt to the higher-speed setting. The "set screws" for the motor-side "gear thingy" were coming out and would clearly eat into the belt as it operated. These set screws are basically intended to stay "sunked in" on the high-speed track of the motor-side gear thingy. So I tightened them as best I could but when I turned on the machine, the centrifugal force caused them to roll back out and damage the belt. I explained my situation to proxxon support and thankfully they sent a new belt by express mail at no charge. I've taken out the set screws entirely and it seems to work OK so I'm not sure what they're really good for. If you get one with loose set screws I personally recommend removing them rather than trying to secure them properly. AFAICT, it's not easy to secure them because there is no "head" to these screws.

This drill press is made to drill tiny holes. I use it for #6o drill bits and smaller. What material you choose to make holes in will determine drill speed, and vertical feed rate. The quill, the part that rotates is supported by precision bearing races. This makes the rotational error very small. Collets are supplied with the machine and are very accurate and well made. I bought the additional small adjustable chuck. This will allow me to drill holes up to 1/4 inch. This drill press cannot be used as a larger machine can be ie. 1/2" holes, using sanding drums , or large wood drill bits. It does precision drilling with tiny drill bits extremely well. Common users would be : jewellers, watch makers, circuit board makers, prototype makers.

Purchased this mini-drill press for wood ship modeling, which I have found to be essential to the craft. My only regret is that I did not purchase it sooner. The operation is very smooth and incredibly accurate -- down to drill bits less than 1 mm in diameter (purchased separately). The set of "mini" chucks allows for precise turning of each drill bit. This is a high quality dril press. Although pricier than other units, it has been worth every dollar I paid for it.
