sample item.

[ihavenofish]

im going to be making an "example" item on my nm-070 (sieg kx1) mill over the weekend and filming it. the intent its to give a good representation of how the machine performs. theres very few videos of these machines, and the few that there are are not really representative of the machines abilities - novakon's own nm135 demo for example.

ill be using a small block of steel (1-7/8" x 6" x 7/8") for this, and will be making a shape that will have straight lines, perpendicular lines, circles, curves, paralell diagonal lines and a flat top and bottom. things that can be mesured after its made to check accuracy, finish, etc.

the plan is then to get it tested on the nm135 and nm200 and make the gcode and setups available.

so this is all well and good, but i had an idea. rather than make a pointless bunch of cuts, i think i should make the file some sort of object thats usefull on all the mills. something for example that a nm135 owner would want, and can run the code to both test their machine, and also get a useful part.

i dont really have any idea what would be a good item though off the top of my head. i thought of things like clamps, but they are much too simplistic for the test/video. likewise i had thought of a spindle clamp for a dremel or proxxon, but it couldnt be universal to all the machines and would need a much bigger steel or aluminium bar to make.

any bright ideas?

Make a spindle flood coolant block for the 135. The idea behind the block is to cool the spindle and allow for much more convenient coolant distribution to the tool. Generally the shape of the block is the shape of the bottom of the head where the spindle exits. Of course there is a hole in the middle where the spindle resides.
Design the part so that coolant could be pumped in from the sump, through the coolant block where it would collect heat from the spindle, and out through a number of lockline that surround the perimeter of the block.

Confused yet?

not confused... but uh.. i get the feeling thats not gonna be 1.875" x 6".



that and it should work with all 3 novakon machines. i dont have an nm135

How bout' a simple touch off block, which could house a cheap dial indicator.

Just a thought....

Hello

how about a T nut slot cleaner

i was going to do an electronic touch block for use with mach. its going to be made form round stock though and done with a turning operation in the spindle. ill probably release the code for that and a video too, but it wont be for a little while.

as for a t slot cleaner... every machine has a different size is one issue.. the second is.. i dont know what that is! is it just a shape that you cram through the slot to knock out chips?

im looking at the thinks i personally need for some upcoming jobs, and they are mostly clamps, riser blocks, and such.

i do have to make some modification parts for the machine, but they are too specific for this example. im porbably gonna video everything i make though.

for this weekend however, all i have is 1/4" end mill, a fly cutter and a small block of steel.
