Production track cuts assembly time, saves costs

Innovative, modular, carriage and rail production system can be used by assembly, process and manufacturing companies to reduce costs and increase productivity.
THK, one of the world's leading manufacturers of linear motion technology, has launched a completely new and innovative carriage and rail production system, that can be used by assembly, process and manufacturing companies to reduce costs and increase productivity.
The new system is called the HMG Multi-motion Guide and essentially comprises a series of modular track or rail sections with the latest specification THK linear motion guide technology.
Track sections are available in a wide range of lengths, widths and straight and curved formats, enabling almost any configuration of production track to be constructed, with single or multiple carriages or blocks being used to move and position workpieces allowing variable capacity.
Unlike traditional production track equipment, the HMG system uses purpose designed linear motion components to ensure that each carriage moves consistently and accurately regardless of the set-up of the rail.
This eliminates potential variations in tolerances between different sections of track and ensures a smooth, almost friction-less motion, with positional accuracy of within +/-0.1mm.
Typical track configurations are circular, U-shaped, L-shaped or S-shaped.
In each case, it is possible to make considerable savings in design and construction time and cost.
For example, a conventional rectangular production track typically incorporates a turntable at each corner to re-align pallets or workpieces; using the HMG system the turntable units can be replaced with a simple curved section of track, allowing the linear motion carriages to move in a continuous path.
Similarly, several rails can be mounted in parallel, while heavier loads can be accommodated by using multiple rails or carriages.
The linear motion guides are robust, high performance units and are capable of being loaded in radial, reverse-radial and lateral directions, with a maximum static load rating of 66.7kN on a single carriage.
They are low maintenance and have a long operating life; a range of options including scraper seals is also available.
