NUMOBAMS Warranty
180 Days warranty time for "control board" after you received our lathe machine.
Send the broken control board back to us in 180 days can change a new control board.
The warranty time since from the day you received machine.
We guarantee the overall working accuracy of the machine, but not the precision of every individual component. All our machines are pre-adjusted and calibrated for high-precision operation upon delivery. Therefore, to verify accuracy, please do not disassemble the machine. Instead, perform an actual cutting test and evaluate the result. Please note that we cannot be held responsible for any accuracy issues arising from unauthorized disassembly. Thank you for your understanding.
Why you need a Machine with DRO?
No matter normal lathe machine or CNC lathe machine, there is movement error on pallet, which we called as "0 movement". On normal lathe machine, it shows as when you turn the handle wheel at the first circle, the pallet would not move,so that you cannot know the accuracy movement distance of pallet by read the handle wheel scale number. There need be a distance between gear and lead screw to move smooth,the bigger the distance is, the error is bigger and pallet move much smooth. The smaller the distance is, the error is smaller and pallet move hardly. So that an accuracy DRO set can help us know the accurate movement distance, if you want make an accuracy working piece and thread, a machine with DRO set is the best choice.
