VTM Series (4 Axis Vertical)
VTM series is the optimally reconfigured version of popular THM series of Thread milling machines. It is ergonomic for machining and optimal chip removal which results in improved surface finish of single and twin material feed screws in cylindrical and conical profile.
Salient Features of VTM Series Thread Milling SPMs
- 4 servo (3 linear + rotary) axes with vertical milling spindle setup.
- FG260 grade Cast iron bed with 4 guide ways. X axis slide is designed with unique & functional step bed with adequate base width to support the vertical structure.
- Vertical spindle design ensures optimum chip removal. Low working height of machine Base enabling direct view of the cutting process to reduce operator fatigue and improve productivity.
- Vertical milling spindle with BT50 taper and hydraulic tool clamping for easy change.
- Machine is designed with coolant tank integrated in the bed
- Custom screens for Screw cutting programs with graphical representation.
- All other features of THM Neo series are carried over ……
