the parts i want to use are:
hiwin HG 20mm rails
hiwin 20mm preloaded balscrews
mcg ID-33004 brush servo ( 4 times ) 1.2 Nm const
gecko 320, grex, mach4
nsk astro psa 35 spindle 6mm max.
fixed supported bearings ( ballscrew )
gortite bellows
fogbuster cooler
the weight off the base is 190 kg. and moving parts, Z-axle is 30kg. xy is 55kg.
The basic calculations are made with the simulation program and are nice,
in all the cases of force on the machine the displacement is exceptable.
rapids with 4000N thrustforce no more than 0.01mm displacemend.
The holes for bolts etc. are made at the end en will decrease the stiffnes ofcourse, hope it will be exceptable ( do think So) |
