Juaristi AP 110

The Juaristi AP 110 machines wind turbine components at the largest scale: nacelle housings (typically 3–5 m long, 2–3 m wide, up to 20,000 kg) requiring precision bearing bore alignment; main shaft bearing housings (600–1,000 mm bore diameters requiring ±0.010 mm roundness); gearbox planet carrier housings with multiple precision bearing bores; yaw ring support frames; and rotor hub arms. Wind turbine components are typically cast ductile iron or fabricated steel weldments — both materials Juaristi's boring machines handle routinely. The energy sector's growth in wind power manufacturing has made this one of Juaristi's primary application segments.

Without a rotary table, accessing multiple faces of a large workpiece (>3 m diameter) requires manual repositioning of the workpiece on the floor plate using overhead cranes and precision measuring equipment. The column X-axis travels along the floor to position over each bore location. Between bore operations on different workpiece faces, the shop uses precision square and level measurement to locate the next reference datum and reposition the workpiece. Manual repositioning on large boring machines is standard practice in shipbuilding and energy sector job shops — the rotary table is a productivity enhancement for smaller workpieces that can fit on the table, not a requirement for all applications.

Custom-configured AP 110 machines have typical delivery times of 12–18 months from order confirmation and deposit receipt. Juaristi builds each machine to order — the specific column travel length, table configuration, spindle power, and control options are determined at order time. The long delivery time reflects the machine's size (major casting lead times are 3–6 months), precision machining of the machine components, and assembly/testing at the Mondragón factory. Buyers should plan projects with 18-month machine procurement timelines. Rush configurations may be available at premium pricing if factory capacity allows.

The AP 110 with 45 kW spindle motor delivers maximum torque at the spindle at low RPM — approximately 1,500–2,500 Nm depending on the gearbox ratio used. For large-diameter boring (300–500 mm diameter in cast iron) at 50–100 RPM, this torque provides the force required for single-point boring bars at aggressive feeds (0.2–0.5 mm/rev). The machine's wide speed range (4–2,500 RPM) covers everything from slow large-diameter boring to high-speed small-diameter drilling and milling at faster speeds.

Yes. The AP 110 has full XY contouring capability — face milling with shell mill or indexable insert face mills up to 400–500 mm diameter is standard. The spindle's 45 kW power provides adequate material removal for face milling large surfaces on cast iron and steel workpieces. Common face milling applications include: flange faces for sealing surfaces; split-line faces on large housings; bearing housing face faces; and general surface preparation before precision boring. Face milling on a boring machine is generally less productive per unit area than on a dedicated milling machine, but enables completing both boring and face milling operations in one setup for large workpieces that cannot be transferred between machines.
