  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

    Set screws for aluminum plate

    After using a nice sharp chisel to get them flush with the table, he would have loads of Christmas trees to give away. Although, they sound like a good idea really.

    If you need any higher level CAD work....

    Thanks for letting us know. Have several projects coming up in the next couple of months, some of which, will need outsourcing. Automation cells in particular. PTP should be completed mid February, early march for design approval. These cells will be piercing, drilling, tapping units. Would be...

    Where to buy Parting Blade in Victoria?

    With only 5% cobalt.. That price is much more than I would pay as well, even if they through in free shipping. I think amazon would be your best bet as well, with 8% cobalt for less $$.

    Tips/Techniques Coolant, the overlooked tool

    Ok, I will have a looksee for a 4 flute straight helical endmill without coating. What grade carbide endmill would you suggest ? Nano, ultrafine or submicron, or would it matter, as long as I'm using coolant ? I like to see a .02-.025 chip load in 6000 series AL - on a manual miller...

    Tips/Techniques Coolant, the overlooked tool

    Sounds good. I will try your best solution in Aluminum. What type or uncoated carbide endmills are you using? How many flutes? Helical ? Variable flute?

    Tips/Techniques Coolant, the overlooked tool

    This is where advanced coatings along with Exocarb come into the equation. I've left machine's running finishing toolpaths in 3D overnight. Hardened A2/ D2 with a 2flute 1/2 ball nose. Using a .012 stepover with a uniform .02 stock over the surface with air. No polishing required afterwards...

    I suppose, they are much more advanced in the machining world?

    Tips/Techniques Coolant, the overlooked tool

    We don't have any issues with heat build up when using carbide with air on the mills. With a good speed, feed and chip load, the heat is in the chip, not the tool or workpiece. If you are generating too much heat, the problem isn't with your tooling.

    Tips/Techniques Coolant, the overlooked tool

    Looks to me like they used a 6 flute endmill on the first go, then, used a 4 flute vari-mill endmill to pull it off. Not a good test IMO, but hey, its on you tube so coolant is the way to go. I will stick to milling with good coatings and air, all day long....
