PAMA Speedram 1000

In a table-type boring mill, the workpiece is mounted on a CNC-controlled table that moves in X (longitudinal) while the spindle moves in Y (vertical). In a floor-type machine like the PAMA Speedram, the workpiece is fixed to a large floor plate and the column traverses in Z (longitudinal), the headstock moves in Y (vertical), and the ram extends in X (horizontal) to reach the work zone. Floor-type machines handle parts too large or heavy to mount on a conventional table — often from 5,000 kg up to several hundred tons for the largest applications.

The W-axis is the spindle ram extension — a quill that extends from the headstock to increase the spindle's reach without moving the column. The Speedram 1000's 750 mm W-axis travel allows the spindle to reach into deep bores or access recessed surfaces without repositioning the column. It is used for boring deep holes, reaching into pockets, and for operations where column movement would be impractical or cause excessive vibration at extension.

The optional CNC facing head replaces the standard spindle attachment and adds a U-axis — a radially adjustable cutting tool that rotates with the spindle face. This enables turning, facing, and grooving operations on large circular features (turbine casing flanges, bearing bores, gasketed faces) without moving the workpiece to a lathe. The U-axis is programmed via the Siemens 840D sl control. Face diameters up to several meters can be turned and faced on the machine in a single setup with the workpiece.

The Speedram 1000 uses a 100 mm spindle; the Speedram 1500 uses a 150 mm diameter spindle with proportionally higher torque (typically 20,000+ Nm) and spindle power (50–75 kW). The Speedram 1500 targets the heaviest applications — nuclear component machining, large ship engine components, and the largest turbine and compressor casings. The Speedram 1000 covers the bulk of aerospace, energy, and heavy engineering applications at a lower investment. Choose based on maximum spindle diameter and torque required for your heaviest roughing operations.

PAMA provides detailed foundation and floor plate specifications for each machine configuration. Typically, the Speedram 1000 requires a machined cast iron or welded steel floor plate with precision-ground T-slot surfaces, embedded anchor bolts, and a concrete foundation of sufficient depth and reinforcement to support the machine weight plus workpiece. Floor plate levelness must be within 0.02 mm/m. A foundation survey and engineering package from PAMA is typically included in the machine purchase — budgets for 6–12 weeks of foundation preparation.
