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

The machine stands out due to its robust construction made from high-quality GJL 300 cast iron. Steel flat guideways combined with INA-SCHAEFFLER RUS roller linear bearings provide maximum rigidity, superior stability, and consistently high precision throughout the entire service life of the machine.

The spindle headstock is centrally positioned within the portal column and features a combination of slideways and preloaded linear guides for optimal stability and dynamic performance.
