Makino V33i Graphite

New V33i Graphite machines typically price between $180,000 and $260,000 depending on configuration. Adding the 30-tool magazine, probing package, and advanced automation interfaces pushes toward the upper end. Used V33i machines from 2016-2021 trade between $90,000 and $160,000 depending on hours and condition.

The V33i ('i' for improved) features updated servo drives with better acceleration and deceleration characteristics, refined SGI.5 contouring parameters for improved surface quality, and an updated Hyper-i/Pro 6 control interface. The core mechanical platform is similar, but the dynamic performance improvements translate to measurably better electrode surface finishes and shorter cycle times on complex 3D electrode geometries.

Choose the V33i if most of your electrodes fit within the 450 x 350 mm travel envelope and you want the more compact, cost-effective option. Choose the V56i if you regularly produce medium-to-large electrodes exceeding 400 mm in any dimension, or if you need the larger table for multi-electrode setups. The V56i's larger work envelope covers a broader range of electrode sizes but costs more and consumes more floor space.

Yes, the V33i can machine copper electrodes, though it's optimized for graphite. Copper cutting produces metal chips rather than dust, so the dust extraction system isn't directly beneficial for copper work. The 30K RPM spindle and HSK-E40 taper work well with copper, but shops doing significant copper electrode volume should consider a general-purpose high-speed VMC that can handle both materials without the graphite-specific compromises.

The V33i uses a sealed enclosure that creates negative pressure inside the work zone, preventing graphite dust from escaping into the shop environment. An integrated extraction system captures dust at the source and routes it through multi-stage filtration. The system typically includes a pre-filter for large particles and a HEPA-class filter for fine graphite dust. Regular filter changes are essential — clogged filters reduce extraction efficiency and allow dust to settle on machine components.
