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 moving column T-design, engineered for demanding heavy-duty machining applications.

The machine impresses with its robust construction made from high-quality GJL 300 cast iron. Steel flat guides combined with INA-SCHAEFFLER RUS recirculating roller shoes ensure maximum rigidity, highest stability, and consistently high precision throughout the entire machine lifespan.

The spindle headstock is centrally located in the portal column and features a combination of slideways and preloaded linear guides for maximum stability and dynamic performance.
