Juaristi TS3

The Juaristi TS3 is a table-type horizontal boring and milling machine positioned as the mid-range workhorse of the Juaristi boring mill lineup. With a 130 mm (5.1 in) spindle diameter and X/Y/Z travels of 2,000 x 1,600 x 1,250 mm, the TS3 covers the sweet spot for medium-sized boring work in mold bases, machine tool components, gearbox housings, and general heavy mechanical parts. It shares the same Basque Country manufacturing heritage and hand-scraped construction as the larger TX and MX series, but in a more compact and cost-effective package.

The TS3 spindle runs at up to 3,500 rpm with 30 kW (40 hp) of continuous power, making it notably quicker on lighter cuts and finishing passes than the larger TX3S. The W-axis quill extends 600 mm, which handles most medium-depth boring operations without the need to reposition the headstock. Tooling uses BT50 or ISO 50 shanks through an automatic tool changer with 40 to 80 tool capacity. The integrated rotary table provides 360-degree CNC indexing, enabling four-sided machining of cubic workpieces in a single setup.

Built on a one-piece Meehanite cast iron bed with hand-scraped box guideways, the TS3 delivers the vibration damping and long-term accuracy that Juaristi machines are known for in European production shops. The guideways use turcite-lined surfaces on hardened and ground ways, and all axes read position through Heidenhain glass scales. The standard control is a Heidenhain TNC 640, with Siemens 840D SL as an option. Thermal compensation through the control helps maintain bore position accuracy during long production runs.

New Juaristi TS3 machines price in the $350,000 to $550,000 range depending on table configuration and options. This positions the TS3 below the TX3S in both size and cost, making it accessible to a broader range of shops. The machine competes with Doosan DBC series, TOS Varnsdorf WHN series, and Femco BMC boring mills. Used TS3 machines from the 2008-2018 vintage appear occasionally in the $150,000-$300,000 range.
