Rosa spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Rosa spindles and motor spindles. Rosa is an Italian manufacturer of surface grinders founded in 1964, now part of Rosa GrindTech together with the Favretto brand.
Rosa, an Italian builder of surface grinders
TLDR: Rosa Ermando S.p.A. (Rescaldina, near Milan, founded in 1964 by engineer Ermando Rosa) builds surface grinders. It took over Favretto in 2017 and brought both brands together under Rosa GrindTech.
Rosa Ermando S.p.A. is based in Rescaldina, in the province of Milan, and was founded in 1964 by engineer Ermando Rosa. In 2017 it took over Favretto S.r.l., another historic brand of surface grinders, and the GrindTech project was born from bringing the two companies' know-how together.
The ranges include single-column grinders, from 600 × 300 × 330 mm to 7,600 × 1,100 × 1,000 mm, and gantry grinders, from 1,700 × 1,550 × 800 mm to 8,500 × 2,500 × 1,175 mm. The Iron, Steel, Silver and Rotor series are widely found on the used market.
Wheel spindles from 5.5 to 22 kW
TLDR: The Rosa catalogue gives wheel spindle ratings from 5.5 kW (Iron 6.3) to 15 or 22 kW (Steel, Silver, Rotor), with wheels from 350 to 450 mm in diameter.
According to the manufacturer's catalogue, the Iron 6.3 series uses a 5.5 kW (S6) Rosa spindle with a Ø350 × 25-50 × Ø127 mm wheel. The Iron 08.6 to 18.6 move up to 11 kW (S6) with a Ø400 wheel. The Steel and Silver series go up to 15 kW, 22 kW on request, with a Ø400 to Ø450 mm wheel. The Rotor series, with a rotary table, offers 11 kW on the smaller models and 15 to 22 kW on the larger ones. The catalogue specifies neither the bearings nor the cooling method: we confirm them in our quote.
Not to be confused: Rosa and Rosilio are two different companies.
