Ok, I've taken the plunge. I'm finally entering the world of CNC.
I decided a while back if I was going to do this, I was going to do it properly, so I hired an engineer to design me a CNC suited for one purpose only, building guitars.
Long story short, I gave the engineer the specs of Dougs machine telling him "This guy knows what he's doing" and then the engineer pumped out some specs. I passed them along to Doug who (thankyou) has offered some valuable advice and then the specs were revised to the following:
X-Travel 1700mm.
Y-Travel 1000mm.
Z-Travel 200mm
These might actually be a fair bit larger on the finished machine.
Aluminium & steel construction.
Maximum recommended cutting tool capacity Ø12.7mm.
Fitted with (miniumum) 425oz-in stepper motors on each axes.
X-Axis:
Dual Rack & Pinion Drive System.
30mm linear bearings running on supported precision ground hardened shafts.
Stepper motor pinion drives spring loaded to minimize backlash with rack.
Y-Axis:
Rack & Pinion Drive System.
25mm linear bearings running on supported precision ground hardened shafts.
Stepper motor pinion drive spring loaded to minimize backlash with rack.
Z-Axis:
16mm x 5mm pitch ballscrew leadscrew.
20mm linear bearings running on supported precisions ground hardened shafts.
Stepper Motor mounted to leadscrew with self-aligning coupling.
Controller:
Fitted with Bipolar Stepper Motor Drivers.
48VDC power supply.
Breakout board with IC buffer & 25pin parallel port interface.
Fitted in enclosure with cooling fan.
25pin serial cable for connection between the control box and your computer.
Output relay for switching of Spindle.
Travel over-run limit switch inputs.
Automatic Tool Change (ATC) System:
2.2kW Water Cooled Spindle with ATC.
6 x Collet Chuck Tool holders.
1 x Tool Rack with 6 tool forks.
Includes spindle mount, water cooling system, pneumatic valving system, VFD setup & cabling.
Aluminium T-slot Table, (using 160x40 profile T-slot Extrusion):
The machine will also have a remote hand controller and a dust extraction hood.
Long story short, this thing is costing me an arm and a leg, enough that I've had to take out a bank loan using my house as security and I have no idea what the hell I'm doing, so I reckon you guys are my "call a friend" at the moment!
It'll be next year till the machine is built and delivered, but I wanted you guys to be the first to know.
Cheers
