The Cincom L20 performance and operability have been greatly improved and the machine has evolved to become environmentally friendly.
The Cincom L20 (Type VIII/X/XII‑B5/XII‑ATC) supports Ø20 mm bars (upgradable to Ø25 mm) with machining lengths up to ~200 mm in GB mode. It features a main spindle rated at 10,000 rpm (3.7–5.5 kW) and a back spindle also at 10,000 rpm (1.5–3.7 kW).
Tooling capacity ranges from 38 to 45 tools depending on the configuration, with gang rotary tools up to 6,000 rpm and back rotary tools up to 7,500 rpm. Feed rates reach 32 m/min, with the Y2 axis at 8 m/min. The machine consumes approximately 8.3 kVA (average ~4.5 kVA), and weighs around 2,680–2,900 kg. Measuring ~2,222 × 1,625 × 1,835 mm, it includes B- and Y2-axes, an optional ATC, and LFV chip control. Ideal for high-mix, small-batch jobs in India’s automotive and electronics sectors, it is supported by Citizen’s Bangalore service center for demos, training, and process optimization.
