Stone Machine

[ramsbury]

Well folks.
I have decided to Build a Stone profiling machine.
After looking at hundreds of machines online and at stone fairs and shows decided they are Either too small for what I can afford. so expect to build a machine to the same size of commercial machine for the same price as a smaller machine.

Reason to increase production.

Began last weekend
Buying the Steel..

Machine Dimensions are:

2700mm long 2440 x axis.
1350mm wide 1220 Y axis.
1500mm high. 450 Z Axis.

Steel box section rectangular 120mm x 60mm x 5mm..

Nema 34 1600oz pair on X to drive two R&P and on Y to drive a single ballscrew Undecided what size,, on Z probably 820oz simply to have the guts to drive a 3kw motor with a diamond profile finger into stone with Cuts at 10mm deep Max per pass, without dropping steps.
commercial hexagonal rails and profiled rollers on x because of stone dust and water
still looking for a supplier.

THK rails for Y and Z

mainly based on a 3 axis Stone saw But with a spindle cutter instead of a Disk.
the Table is my design which will take 500kg without too much deflection.

the maths works out at 0.45mm deflection at 3 metres unattached so should be able to achieve .04 at least after welding legs on.


Cut the steel two days ago.
Ground the ends and started welding today.
