The customer – Bicoma – is an Italian manufacturer of automation machinery for use specifically in the stone field – cutting marble, stone, granite etc. Bicoma has a proud history as one of the most innovative companies operating in this sector, and are globally renowned for their high-quality machinery production.

 

Their Fast 2000 dry-wire / dry-cut diamond wire cutting machines have an automatic mode that enables them to work with or without operator. The processes are controlled by a programmable logic controller that controls diamond wire breakage, lack of water, labour time, and enables cooling water dispensers and track end (end cut).

 

IMO Automazione in Italy were approached by Bicoma who was looking for a dual solution for their Fast 2000 machines, which were using a variety of components from various manufacturers. They were trying to eliminate some technical issues they had experienced with their existing drives, whilst also looking to reduce the component costs.

 

Selected for extreme working environment

After evaluating the market, two of IMO’s SD1 drives were selected. The parameters for selection were: their ability to communicate with each other; accuracy; reliability. Another major factor was their suitability for use in an extreme working environment, the exceptionally challenging and high altitude Apuane Alps. The SD1-4.2A-21 (0.75kW) single-phase variable speed drive was selected to control the linear feed of the carriage.

 

The SD1-115A-43 (55kW) variable speed drive was selected to control the cutting head speed. Using PID control, the speeds are matched to ensure the greatest efficiency of the cutting process, without breaking the cutting cable.

 

The installation of the two IMO SD1 drives not only resolved the technical issue Bicoma was experiencing with previously equipment, but dramatically reduced the individual component costs of the Fast 2000 Diamond Wire Cutting machine.

 

A company spokesperson said “We have chosen the IMO products because they symbolise the Italian mentality and the mentality of the people from “MassaCarrara”. The products are easy to program, strong and offer optimum value for money. There are many companies that manufacture drives, but it is not easy finding a friend that helps you find a total solution.”
