Juaristi TS 3

JUARISTI Boring and Table Type Milling Machine
Model: TS3-MG20
Year of Manufacture: 2005

Machine Overview:
The JUARISTI TS3-MG20 is a high-performance boring and table-type milling machine in a travelling column T-design, engineered for heavy-duty machining operations.

The machine stands out due to its robust construction, crafted from high-quality GJL 300 cast iron. Steel flat guides in combination with INA-SCHAEFFLER RUS re-circulating roller shoes provide maximum rigidity, superior stability, and consistently high precision throughout the entire service life of the machine.

The spindle head is centrally mounted in the column portal and features a blend of slideways and preloaded linear guides for maximum stability and dynamic performance.
