NCMT has been appointed sole agent, Britain and Ireland, for the Speroni range of presetting equipment.
Speroni, headquartered in Pavia, Italy, the company boasts 5,000 installations. Its systems' highlighted differentiator is their use of aged pearlitic cast iron for the machine structure. This, it is claimed, gives the units greater stability than that of competitor machines made from granite or light alloys.
Commonality of materials and solidity of construction reduce the need for frequent recalibration, so software compensation, as offered by other manufacturers, is not required, since there is no misalignment for which to compensate.
In addition to this, Speroni's use of rigid, repeatable tool clamping in the toolsetter spindle that duplicates the machine tool location enhances accuracy and repeatability.
With this total package, the company claims a repeatability of ±0.002 mm, although according to Elrich Braendle, international product manager: "We define repeatability differently to competitors".
The core structural stability and strength also allows the company to upgrade customers' systems as their requirements progress. And the range starts with the lowest cost unit, the STP 34, a manual machine costing €8,000, while its top-of-the-range STP Esperia modified to handle a 400 kg crankshaft cutter is €400,0000, for example. The Esperia range offers up to a 1,200, 1200 operating area capacity, incidentally.
In between these two ranges is the STP Magis, launched at the last EMO show in 2007. It is a manual model featuring a camera. The machine has a standard X-axis range of 50 to 350 mm and is available in three column sizes – 400, 500 and 600 mm travel.
Ease of use is another underlined feature of its machines, the company having developed its own Pro Vision software: two hours installation and six hours' training, is the claim.
A final, and rather unusual feature, is the company's ability to supply combined presetter and heat-shrink tooling capability in the same machine, with its Ez Shrink unit. This system employs the Schunk Tribos system, and the achievement of tool length setting within ±0.005 mm is claimed. The company first introduced a system like this 10 years ago, to Boeing.
