Specialists in the supply of new and re-engineered power presses, coil handling equipment and minting machines, MM Power Press required a cost-effective motor and drive combination capable of providing an accurate and high-speed system for feeding galvanised plaster bead into a Haulick Roos power press.
The power press was supplied by MM Power Press to the Tamworth manufacturing operation of construction giant Simpson Strong-Tie, for the production of thin coat bead which is used by builders to create neat and even wall edges.
After considering servo feed systems from a number of manufacturers, MM Power Press opted for a system devised and supplied by Goodwin Electronics, a company whose motion control expertise MM Power Press has called upon for a number of previous projects.

With EDM wire cutting, especially with the Agie cut Evolution and Agie tron Innovation machines, Christian Dunkel ocquired a decisive competitive advantage in jig and fixture manufacture.
MM Power Press Managing Director, Michael Meagher, explained, "We knew from experience that Goodwin Electronics provide workable, reliable and affordable solutions to a variety of demanding motion control challenges.
In this particular instance, Goodwin developed a high performance system which suited our needs perfectly at a significantly lower cost than solutions offered by other companies we approached.
The level of technical support and customer service provided by Goodwin also contributed to our confidence in the company's ability to follow the project through successfully".
Working closely with staff from MM Power Press, Goodwin Electronics developed a high performance servo feed system based around the class-leading Sigma II Series AC servo drive from Yaskawa.
The resulting system is a high-speed, low maintenance precision feed whose combination of performance, versatility and reliability has won the overwhelming support of machine operators at Simpson Strong-Tie.
The Sigma II's combination of motor and drive work together to feed the Haulick Roos power press with 50mm lengths of bead at a rate of 380 lengths per minute (maximum rate is 800 x 50mm lengths per minute).
The system incorporates a steel reinforced nylon belt drive with a pair of 2:1 ratio gears and delivers an impressive repeatability level of +/-0.05mm.
Compact and fully enclosed, the system requires minimal maintenance to ensure that the productivity of the power press is not compromised, an important factor considering the machine's round-the-clock operation.
Another important feature of the Sigma II system is the range of advantages inherent in the use of CNC servo feeds.
The system's user-friendly software was developed by Goodwin specifically for this application and allows for the simple and speedy programming of pitch lengths (progression), together with velocity, acceleration and deceleration.
The system also includes an S-curve facility which helps to eliminate slippage and overshoot, contributing to the trouble-free overall operation of the power press.
A 'job memory' function helps to minimise the potential for operator error by enabling the rapid switch between pre-programmed tasks whose set-up details are stored within the drive's memory.
A speed programmable forward and reverse jog function contributes to a further simplification of the machine's set-up.
MM Power Press' Electrical Engineer, Chris Bentley, explained, "The system's software has been developed for a combination of versatility and ease-of-use, incorporating a number of features which help to simplify programming and streamline the machine's operation while dramatically reducing both set-up times and the risk of operator error".
In a final endorsement of Goodwin Electronics' expertise and its contribution to the success of the power press supplied by MM Power Press Service, Simpson Strong-Tie Line Supervisor, Brian Davey, explained, "Every aspect of the feed system's design and configuration helps ensure that the power press is simple to operate and receives a high-speed and consistent supply of bead.
This enables us to maximise the machine's productivity and manufacture class-leading components on whose quality our customers can always rely".
