Advantages
- Maximum versatility at low operating costs
- Ergonomic design and excellent visibility of the workarea
- Easy access to working area
- Easy loading/unloading of heavy parts
- Simplified maintenance
- Environmental sustainability
Tools
- High-stiffness universal milling head(power up to 33 kW)
- T-frame morphology: transversal moving column with no ram
- Moving columns along transversal axis ensures constant geometric accuracy and removal capacity in the entire work area
- Sliding on large-size re-circulating roller guide-ways to grant high stiffness and acceleration
- Tool cooling and chip conveyor tanks integrated in Xand Y axes basements
Configurations:
- Thora T is equipped with a moving table
- Thora RT is equipped with an integrated rotary table moving along X axis:
- is driven by motors through a precision rack and double-pinion transmission system, with electronic backlash recovery
- It is available with the following dimensions: 1.000 Х1000, 1.000 x 1.250, 1.250 x 1.250 mm
- Both Thora versions are available in two configurations:
- “basic”, conceived for mechanical applications with universal head and maximum working speed of 24 m/min
- “speed” with continuous 5-axis head, maximum working speed of 45 m/min and top dynamic performance
Thora, included in Sachman’s commercial range of products, meets the machining requirements of:
