[toneV8]

I want to build 2200mm x 1600mm x 350mm working area approximately 86'' x 63'' x 14'' cnc router. I plabne to buy supported linear rails and anti blacklash ballscrews from linearmotionbearings2008 Chai. Machine will be made from steel tube 130x100x10mm, 100x100x8mm and 80x80x6mm.
Is ballscrews and nuts C7 from linearmotionbearings2008 really anti blacklash.
What diameter and lead 5mm or 10mm is best for this size machine and electronics.

Is this electronics from kelinginc good for this size machine or to find something else.

I change my mind not tu buy from linearmotionbearings2008. I decide to buy Hiwin HG 25-R rails and HGW 25-HC-ZO-H super heavy duty blocks. Are they good to use for all 3 axis.

Rails:
HG 25-R 2x2600mm
HG 25-R 2x2000mm
HG 25-R 2x700mm

HGW 25-HC-ZO-H 12 bloks

HIWIN makes some really nice stuff, though I never used it....

Hiwin changes the part number slightly when you go from the basic linear bearing through to the highest accuracy ones. This has a big difference in price tag, and may or may not be noticeable on your machine. In general, you are probably no worse off, but low-end Hiwin is not the necessarily the same as THK or NSK.

Hiwin goods just come.

[Khalid]

Very Nice decision on THK..What is the price of the rails and blocks?

[toneV8]

It is not THK it is Hiwin.

Price 1200€.

[toneV8]

Is it good idea to use A4 grade 18/8 ( 316 S16 ) stainless steel hex socket cap screws for rails.

Can someone suggest what kaind type Hiwin ballscrews to use, there are so many.

Thanks

I got prices for Hiwin ball screwss:
dia 20mm lead 5mm 930mm long with nut and end machined ball screwss peeled 630€
dia 25mm lead 10mm 930mm long with nut and end machined ball screwss peeled 670€
Hiwin end supports 370€ fixed and 95€ floated
It will cost me fortune for all 3axis.
Hiwin rolled cost much less 20-5 1000mm 30€, nut 75€ but accuracy gradeIT7 ball screwss 0,052mm and nut 0,02mm ( oversize balls ).
My question is: how good IT7 grade is for machining wood, plastic, aluminium, when machine work couple hours engraving, cutting something, what dimension will part have. Is with IT7 backlash will be to big.
For end supports I plane to buy chinese end supports BK and BF and replace bearings with SKF bearings.
