My actual cutting parameters for aluminum sheet: Material: 1100 aluminum (I’ve cut 1mm and 2.5mm sheets) Feed: 600mm-min or 24IPM (I’ve used 800mm-min, but now I’m being conservative) End-mill: 4-flute 1.5mm carbide. I’ve used 2-flute and 3-flute; the more flutes, READ MORE
I should say the hardest step in making this part was to press the start button (I’m a chicken). This 1mm sheet was held to a mdf plate using Carnauba; that seems to work nicely. Badly I made a mistake READ MORE
Up to this point I’ve worked in the lathe and the mill without worrying too much about speed and rpm calculation, trusting in my own experience and “feeling”, as a lot of hobbyists, I guess. Tooling wearing wasn’t ever an READ MORE
Today I’ve successfully tested the spindle controller box; the DigiSpeed board seems to work nicely, without any issue. I will connect the motor overheating sensor signal to the e-stop input; I’m not sure, but a e-stop signaling seems better than READ MORE
This thing is almost ready to cut. Now I’m working on the spindle controller; just a new plastic box and integrating a DigiSpeed board. I guess the first thing I will cut will be a encoder wheel for the spindle.
It seems an agile task board may be useful even if you don’t have a team. It allows to easily visualize how much work remains and reminds you what you should do. Nice.
My cnc mill itsn’t ready yet, but I hope it will be soon so I’ve been starting to learn a bit of gcode. Meanwhile here are my homing switches. My approach here it’s very similar to the homing switches I READ MORE
Here I will share some thoughts regarding Sherline milling machines. First, Sherline mills are great machines. Almost unbeatable price/quality. Compact and lightweight. Lots of accessories and even a cnc kit. Second, these are nice machines, but not perfect. It seems READ MORE
A cover for the Sherline mill it’s a must if you wish your mill last. This is the typical “accordion” cover, a very practical solution actually: Now here’s the leather/delrin cover I actually use. Tough not pretty, a good thing READ MORE
I don’t know why but I always end doing things the hard way. Here’s some of my current work. Easy to guess what I’m trying to do.
