Recently at the CNC BBQ in Melbourne I spoke to a few people there about some of my projects. But none have really been posted.
So here they are. Mainly a machine called RPM.
It is a router that 2 mates are building. Rod M and Rod P.
So that's where the RPM comes from.
So we sat down and looked at what parts we had and how it was going to be built.
Out came the linear actuators, linear rail, high speed spindles, driver boards, Alloy plate, Steppers and Ballscrews that we just had sitting around.
First the design. Rod M builds him machines with strength and precision, so we looked at the machines he has built and the addition that we wanted from those machines.
The usual things:
*Designed to covers ballscrews from dust and swarf
*Ease of clamping jobs of all types
*Easy to clean after jobs
*Type of spindle to use
*Ease of machine manufacture with maxium rigitity
It has a cutting envelope of 300 by 210 by 120
Which is an A4 size sheet. Perfect.
First photo is the base frame which is made from 100 by 10 flat and 40 by 6 angle.
Second has the table sitting on the frame. It has grub screws next to each mounting screw so that we can dial the table to the Z axis. Push pull fixing.
Third photo is the Y and Z axis which are actuators and they are ready to mount to the gantry sides.
Enough rambling here are some photo's
