I initially designed my DIY CNC router with 1605 1500mm ball screws. These were inexpensive foreign made rolled C7. No complaints.
Now I want more ipm/speed so I started looking for similar inexpensive 1610 ball screws. The 10 mm pitch screws are 60-150% more expensive for the same class 5mm pitch screw.:tired:
Why is there such a difference in price?
