Custom Motorized Curved Rail Systems

For transporting light payloads we can design and manufacture custom curved rail systems.  These are cost effective for Original Equipment Manufacturer's (OEMs) that make a series of idential machines or instruments.

These products are typically found in Scanning and Imaging Systems such as Medical Imaging instruments or Industrial Inspection systems.
Why use this type of product?  Lightweight, less complicated, and space saving over a conventional multiaxis system.

Application Details

Customer needed to slowly move an imaging camera acrossed the surface of an airfoil while gathering data for inspection analysis.

We designed and manufactured a curved guide system to the required (customer provided) motion profile.  The rail, made of aluminum material, required extensive machining to achieve a very lightweight product.

Complete assembly weight is about 0.5 kg (~ 1.0 lb).

Motor and Drive System

The carriage is driven back and forth along the curved rail motion path via a Nema 17 size stepper motor.

An Arcus Single Axis standalone USB Controller plus Driver, ACD-SDE, is used for drive and control.

Carriage plate is connected to the rail via three cam roller bearings.  A polymer tire (yellow color in photos) installed over each bearing enables smooth quiet movement.

The motor is convienently offset a short distance from the center of the carriage allowing the customer a large surface area (see blue arrow in the front view photo) for attaching their camera mechanism.

A camera, sensor, or other type of payload can easily be mounted to the carriage.
