Sigma spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Sigma spindles and motor spindles — an Italian manufacturer of 3, 5 and 6-axis vertical machining centres, part of the international FFG group, designed for machining large workpieces.
Sigma, Italian manufacturer of vertical machining centres since 1950
TLDR: Sigma S.p.A. (Piacenza, Italy, active since 1950, FFG group) designs 3, 5 and 6-axis vertical machining centres intended for machining large workpieces, with Heidenhain, Siemens or Fanuc CNC controls depending on the configuration.
Active on the market since 1950, Sigma S.p.A. joined the international FFG group, which today manufactures and assembles the machine range in its plants in Piacenza, Italy. The manufacturer offers 3, 5 and 6-axis vertical machining centres suited to machining large workpieces, with a choice of Heidenhain, Siemens or Fanuc CNC controls according to customer requirements. The range spans compact configurations, such as the ZENITH series, up to more complete centres designed for general engineering and the machining of large prismatic parts.
A range of mechanical spindles and motor spindles for production
TLDR: Sigma machining centres are fitted with mechanical spindles and motor spindles with an ISO 40 interface, with rotation speeds of up to 18,000 rpm for power ratings in the region of 7.5 kW on standard configurations.
Sigma vertical machining centres integrate mechanical spindles and motor spindles with an ISO 40 interface, sized for industrial production use on medium to large workpieces. Depending on the model and configuration, the rotation speed can reach up to 18,000 rpm, for power ratings typically in the region of 7.5 kW on standard configurations. These spindles, combined with the various available CNC controls (Heidenhain, Siemens, Fanuc), offer good versatility in a general engineering workshop.
