Digital encoder and readout improves
lock output
A digital encoder and readout system has helped a leading UK designer and manufacturer of household and commercial security products to improve production of its new range of multi-point locks.
ERA Products, one of the UK's leading designers and manufacturers of household and commercial security products, has improved production of its new range of multi-point locks with the help of Newall Measurement Systems's Spherosyn digital encoder and SA 100 readout system Using a purpose-built manufacturing cell employing the latest CNC technology to ensure maximum flexibility and the highest levels of precision, ERA began production of the new range of locks at its manufacturing plant in Willenhall, West Midlands in 2001

'Ball' technology to feature in DROs
Reinforcing its reputation for innovation, Newall Measurement Systems will be unveiling several major new developments in linear encoder and readout technology at MACH 2002.
Digital encoders and DROs designed to reduce costs
Several major new developments in linear encoder and readout technology are aimed at reducing costs for machine tool builders and systems integrators.
However, to continue ERA's ongoing policy of product development, Scott Bailey, Production Engineer at the Willenhall plant, identified potential opportunities to improve the production process and increase accuracy.
Further examinations revealed that holes designed to accommodate screws which keep the front bar and drive bar of the multi-point lock in place, were occasionally minutely out of line.
Although measuring only fractions of a millimetre, these discrepancies provided the company with the opportunity to refine its production process even further and minimise any future maintenance requirements.

Digital linear encoder is 'on the ball'
Featuring a novel 'ball' technology, this digital encoder is competitively priced against glass- scale encoders and significantly reduces fitting time and dramatically increases efficiency levels.
DRO designed to increase machine efficiency
Offering OEMs, retrofitters and end users unbeatable value for money, a compact, easy-to-use, single-axis digital readout system is specifically designed to increase productivity.
Bailey double-checked the manufacturing process but found no discrepancies between the technical drawings prepared by ERA's engineering design team and the data input to the new manufacturing cell.
After further investigation, the issue was traced to the method employed to measure the accuracy of the punching.
"Once the bars had been punched, the holes were checked for positional accuracy against a fixed steel rule.
Human error was a factor and a more accurate and reliable method of measurement was required," says Bailey.
ERA contacted Newall Measurement Systems, whose Spherosyn digital encoder has been proven to help engineering companies cut costs and increase productivity in a wide range of applications.
Guaranteed for life and featuring Newall's unique 'ball' technology, the Spherosyn Digital is more robust and less expensive than glass-scale encoders, making it the ideal measuring device for machining operations.
In addition to being highly accurate, the Spherosyn Digital is IP67 rated and is extremely tolerant to shock and vibration; a particularly salient attribute given ERA's demanding production schedule.
Newall also supplied a compact SA100 single-axis digital readout system with a five-year warranty.
The SA100 features scale factoring, linear compensation, axis resolution, head fail detection, plus standard inch/metric and reference functions.
The Spherosyn Digital encoder and readout were fixed to a platform next to the machining cell, enabling accurate measurement of the distance between the holes and easy reference to the designs.
"With the help of Newall's technology, we are able to achieve previously unattainable levels of measuring accuracy," explains Bailey. Request a free brochure from Newall Measurement Systems ...
