Highly Dynamic XY Linear Motor Scanning Stage, Introduced by PI
The L-731 magnetic linear drive ensures high velocity and acceleration.
Motion and precision positioning systems expert PI (Physik Instrumente) L.P. introduces a new compact metrology XY stage - the L-731. The magnetic linear direct drive ensures high velocity and acceleration, ideal for inspection and microscopy.
With a travel range of 205mm square and solid velocity to 100mm/sec, the L-731 delivers high accuracy and smooth motion. Precision crossed roller bearings with anti-creep cage assist guarantee superior guiding accuracy (1.5µm straightness for loads up to 20kg).
An integrated optical reference encoder and limit switch provide further positioning control and accuracy for this compact stage with 5nm resolution. DC servo motor versions are available on request.
Standard and Custom
PI has in-house engineered solutions with over 4 decades of experience working with customers to provide products that meet application demands, and can quickly modify existing product designs or provide a fully customized OEM part to fit the exact requirements of the application.
Applications of the L-731
Fields of applications include automation, semiconductor applications, photonics, bio-nano-technology, metrology, microscopy, micro-manipulation, including cleanroom applications.

T.J. Davies' Retention Knobs
Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
