CNC boring mill SPEEDRAM HP series

horizontalfloorfor large workpieces

Overview
PAMA Speedram HP boring and milling machines combine maximum damping, high rigidity and elevated spindle speed with controlled thermal compensation to deliver precision on medium and large components where horizontal machining is preferable.

Type
Floor type horizontal boring and milling machine.

Design features
PAMA Speedram HP units adopt preloaded hydrostatic guides on the X and Y axes to maximize rigidity and vibration damping. The ram is guided inside the headstock by hydrostatic pads and is fitted with a boring bar using Direct Drive transmission. Both ram and boring bar incorporate feedback systems to compensate for thermal elongation, ensuring sustained precision and local vibration damping.

Customisation and configuration

• Wide range of standard or custom attachment heads
• Various milling and turning table options
• Multiple tool magazines and magazines for tools and attachment heads

Control systems
The range can be supplied with CNC controls from Siemens, Heidenhain or Fanuc.
