Telescopic covers cope with high speeds
Transmission system for telescopic steel covers satisfies the market's demands for high speed performance and acceleration for the latest machine tools.
The P E I Group of Calderara di Reno (Bologna), Italy, one of Europe's leaders in the design and manufacture of machine tool protective covers, is exhibiting its new Synchroline transmission system for telescopic steel covers for high speed at the EMO Hannover 2005 international machine tool trade show This product is the ideal solution for satisfying the market's demands for high speed performance and acceleration of the new machine tools

Synchroline is a synchronised movement system for telescopic steel cover boxes.
Transmission of the opening and closing motion is separate and independent, and is achieved by using a double series of high-resistance belts and roller bearings used as idler rollers that generate a simultaneous and progressive movement of all the boxes by connecting them in an alternating manner.
By eliminating the feed of boxes by mechanical contact, Synchroline generates an even, regular movement of the telescopic steel cover while reducing noise and vibrations during the entire travel, thus ensuring better machining precision at the machine tool.

If only we had CNC on our heavy machines
On visits to heavy engineering and power station maintenance shops, the production engineers there have often said: "If only we had CNC.... Acu-Rite now offers free feasibility studies to fit CNC.
Reliability of the product is ensured by its simplicity of design and construction that eliminates the use of complicated mechanisms subject to wear and rust (like, for example, pantographs), while also making any necessary maintenance simple to perform.
The new telescopic steel cover project, for which a patent application has been filed, makes it possible to build covers having different shapes upon the customer's specific request owing to its flexibility.
In fact, it does not matter how many boxes are used with the system, so it can be applied on all telescopic steel cover box depths and for any width, factors that have always been restrictive in solutions using pantographs.
Synchroline for telescopic steel covers for high speed is a compact solution that takes up little room.
Its use - even in the case of large sizes - does not call for increased mass of the telescopic steel cover, as instead occurs when using pantographs that, owing to their bulk and weight, are the cause of a considerable increase of the moving mass.
The tests that the Bologna company carried out reveal a high speed that reaches up to 150m/min.
for an acceleration of more than 3G.
Synchroline is a more highly advanced system than the solution using pantographs characterised by rigid transmission systems, where the opening and closing movement is always engaged and live.
In the system using pantographs, all of the forces generated in moving the boxes are discharged onto the single connection pins, and their wear and the increase of their respective slacks place the structure at a risk of breaking.
* About the P.E.I.
Group - every year the P E I Group (with 160 employees and three manufacturing plants in Italy having a total indoor surface area of 16,000m2) invests 4% of its turnover in research and development.
Its goal is to offer the market high technology products by optimising its manufacturing processes.
The investment in this new system also falls within the expansion project of S P E R, a company belonging to the P E I Group located in Solarolo Rainerio (Cremona), which is specialised in manufacturing thermic-welded and glued flat covers, sewn round bellows and telescopic steel covers.
Active in foreign markets for more than ten years, the group's exports in 2004 hit 25% of its turnover.
Germany in particular made it possible for the group to reach this figure, as it generated 50% of the group's total exports.
With its goal of strengthening its presence internationally, in 2005 the P E I Group signed a trade agreement in Spain with Exclusivas Rein, a company that has been specialised in the distribution of components for machine tool for the past 26 years, with a strong presence in the territory and well-established experience.
The Spanish market currently absorbs 7% of the Bologna company's export quota, and the number of P E I Group products sold in Spain in 2004 increased 40% over the previous year.
This operation is added to the 1995 opening in Germany of the P E I branch, located in Ismaning, which turns the opportunities coming from the markets of Germany, the Czech Republic, Slovakia and Slovenia to good account.
The Bologna group also distributes its products through trade agreements in France, Belgium, Switzerland, Sweden, several Eastern European countries, Turkey and Taiwan.
'P E I technology' products are found on the American market thanks to an agreement with the company M.P.C.
- Milwaukee Protective Covers - of Milwaukee, Wisconsin, which has subsequently been acquired by American giant A and A Manufacturing Company, a leader in the United States in the manufacture of machine tool protective covers.
It obtained the know-how and machinery for manufacturing thermic-welded covers, roll-up covers and telescopic covers from the Bologna group.
The Bologna group consists of P E I, located in Calderara di Reno (Bologna); Zanini, located in Zola Predosa (Bologna), which manufactures light steel structural work; and S P E R, manufacturer of thermic-welded and glued covers, sewn round bellows and telescopic steel covers, located in Solarolo Rainerio (Cremona).
