8mm Metric Lead Screw / ACME

This 8mm Metric Lead Screw / ACME has an accuracy of 0.05-0.10mm or better. Leadscrew machines are designed to be accurate, strong and reliable. Leadscrew transmission requires little ongoing maintenance, with nut-blocks often having a functional life of longer than 3 years if the machine is taken care of.

All of our Leadscrews are ACME thread TR8x8(P2), in basic terms, this means one revolution of the leadscrew will make a nut-block travel four times further than a standard threaded rod which is only a single start.

Furthermore, this precision trapezoidal (metric) lead screws pitch and diameter are a perfect combination of high torque and speed.

8mm Metric Lead Screw / ACME is the standard for the OpenBuilds' style CNC Machines. Equipped with a large diameter that helps eliminate whipping and a high pitch that allows quick moves at 8mm per revolution.  It's a great power transmission choice for your next build.

Note:

Trapezoidal threads are defined as follows by ISO standards:

• Tr8x8

Where Tr designates a trapezoidal thread, 8 is the nominal diameter in millimetres, and 8 is the pitch in millimetres. When there is no suffix it is a single start thread. If there is a suffix then the value after the multiplication sign is the lead and the value in the parentheses is the pitch. For example:

• Tr8x8(P2)

Denotes 4 starts (as the lead divided by the pitch is 4), 8mm diameter, 8mm lead and 2mm pitch.
