Description
This nut block has been designed specifically for the CNC hobbyist in
mind, to provide a low cost solution for providing linear motion when
coupled with a standard M10 screw thread and stepper motor.
This particular item comprises of a delrin anti-backlash nut block with
a standard M10 1.5 mm pitch.
This pitch is ideal for small hobby CNC machines, where large speeds
are not required, as the fine pitch provides good precision whilst
requiring minimal force from a stepper motor, and thus is suitable for
direct drive with small stepper motors. Due to the high
resolution (0.0075 mm per full step on a standard 1.8 degree motor)
vibration is negligible and a simple drive can be used without
micro-stepping, thus further reducing cost.
The anti-backlash delrin nut is manufactured from grade A delrin
(acetal-homopolymer B) supplied from a reputable European manufacturer.
This material is extremely hard wearing, and normally does not require
lubrication. A pre-set screw adjustment removes any backlash, and due
to its mechanical properties there is minimum friction and wear.
For best performance the screw thread should be polished stainless
steel, in order to minimize friction and wear.
The form of the nut is as a rectangular block with 2 mounting holes,
and as such can be directly attached to the moving base, without need
for brackets or additional items.
