After using the tapping feature of the Nova Voyaget DVR drill press, I can see where there are a few essential enhancements that should be made to how it functions.
First, the depth stop functionality that is present should map to the tapping function to trigger reversal and back out. This is absolutely essential for blind holes and would be a real benefit for through holes as well. I find that when using a high quality gun taps in materials such as aluminum, a 1/4-20 or 6mm x 1.0 tap doesn't register enough load for the system to properly recognize completion of the tapping cycle. This can lead to disastrous outcomes if you don't hit the button in time to reverse the spindle. I would also add that tapping in this case takes three hands. One to hole the workpiece/drill vise, one on the quill handle, and a third to hit the button. electronic depth stop to the rescue.
Another feature I would consider adding is some kind of configurable electronic torque limit. While this may be possible already by manupilating other parameters, it really should be a simple to use feature, like setting a maximum load percentage. I can think of several features, especially tapping that would benefit. Something goes wrong with a tapping operation? Software torque limit set in advance might help prevent a tap from breaking off in the part, affording you the chance to remove the tap by hand without ruining a part.
Third, how about having some way to allow users to upload additional speed information that can be added to the built in speeds, perhaps specifying new materials as well.
Fourth, a more flexible braking option should be added. Braking should be configurable so that the user can set the aggressiveness of the braking and the speeds at which it is applied. Also very useful for tapping, especially if the depth stop feature is tied into tapping and you are doing blind holes.
As you can tell, tapping was a huge feature reason that I purchased this specific drill press and I've had to come up with some workarounds to feature deficiencies right out of the box. Noting that the tapping feature is now hidden under a service menu, I'm curious what the future plans for tapping are and why this feature was taken out of the advanced menu? Was it because there are known, siginificant limitations and it will be moved back once it has been updated or is it an attempt to phase out tapping? I certainly hope the latter is not the case, as it was a huge reason that I bought this specific drill press.
I realize that there may not be a ton of folks with as much interest in tapping features, but please let me know if there is anything I can do to help with refining these features and/or testing.
The tapping feature is one of the key reasons that I am interested in purchasing this machine.
I subscribe totally to the previous contributors reservations and suggestions. Compared with the many other much less expensive drill press models on the marked, by enhancing and adding the suggested features, this would greatly enhance the products USP.
We are working on some improvements to the tapping feature on the drill press and will be releasing them later this year after thorough testing. We have already made some improvements to the tapping feature as well as many other features in our firmware updates, so make sure to stay up to date with the latest firmware from our website:
