Overview

The PAMA Speedram 3 is the heavy-duty flagship of PAMA's Speedram floor-type horizontal boring mill line, featuring a 150 mm (5.9 inch) spindle diameter and the power to tackle the most demanding large-workpiece machining applications. Where the Speedram 2 handles medium to large work, the Speedram 3 is built for the truly heavy stuff — power generation turbine casings weighing 40+ tons, mining equipment frames, large marine diesel engine blocks, and steel mill roll housings that require precise boring across spans of several meters.

The 150 mm spindle with 50 kW of power and a speed range of 4 to 2,500 RPM delivers enormous torque at the low end for heavy boring with large-diameter bars, while the upper speed range supports face milling with indexable cutters. The quill extends 1,000 mm, providing the deep reach needed to bore through thick-walled castings and access internal features without repositioning the workpiece. The automatic facing head option handles diameters up to 1,600 mm for large flange faces and bore counterbores.

Like the Speedram 2, the Speedram 3 features PAMA's signature hydrostatic guideways on all linear axes. At this machine's scale, the hydrostatic system's advantages become even more pronounced — moving a column assembly weighing several tons with sub-micron smoothness and zero stick-slip is simply not achievable with conventional guideway technologies. The pressurized oil film also provides inherent damping that absorbs vibration during heavy interrupted cuts on rough castings, producing better surface finishes than the machine's size might suggest.

PAMA configures the Speedram 3 with X-axis travel from 4,000 to 16,000 mm or more, with the floor plate system extending as far as the customer's facility allows. Y-axis travel ranges from 3,000 to 5,000 mm, and Z-axis column travel from 2,000 to 4,000 mm. The Siemens SINUMERIK 840D sl control manages up to 6 simultaneous axes, and PAMA's proprietary boring cycle software optimizes feeds and speeds for the specific boring bar and workpiece combination. Workpiece weights on floor plates can reach 100,000 kg or more, making this a machine for the heaviest work in industrial manufacturing.

Strengths & Limitations

Strengths

150 mm spindle with 50 kW power handles the heaviest boring operations in the largest industrial castings and weldments
Hydrostatic guideways on all axes provide unmatched positioning smoothness and vibration damping at this machine scale
1,000 mm quill travel enables deep boring through thick-walled castings without workpiece repositioning
X-axis scalable to 16,000 mm or more accommodates the largest components in power generation and marine industries
100,000+ kg workpiece capacity on floor plates handles the heaviest castings in industrial manufacturing
PAMA's nearly century-long specialization in horizontal boring mills ensures mature, proven machine design

Limitations

Price range of $1.5-5M+ makes this machine accessible only to the largest manufacturers and specialized heavy machining shops
Massive footprint and weight require purpose-built facilities with heavy-duty foundations and high overhead cranes
Hydrostatic systems require continuous hydraulic power and specialized maintenance knowledge
Lead times of 18-24 months are typical due to the custom nature of each machine configuration
PAMA service outside Europe requires planning — emergency response in remote locations may be slow

Best For

Power generation manufacturers machining large gas and steam turbine casings, generator frames, and valve housings Marine engine builders boring large diesel engine blocks and structural castings Steel and rolling mill equipment manufacturers machining roll housings, mill stands, and heavy structural frames Mining equipment manufacturers boring dragline, shovel, and crusher components weighing tens of tons Large shipyard machine shops handling propulsion system housings, rudder stocks, and structural castings Nuclear and petrochemical industry manufacturers machining large pressure vessel components and valve bodies

Frequently Asked Questions

01 What does a PAMA Speedram 3 cost?

PAMA Speedram 3 machines price from $1,500,000 to over $5,000,000 depending on travel configuration, floor plate layout, and automation options. A basic configuration starts around $1.5M, while large fully equipped installations with extended travel and automatic tool/head changers can exceed $5M.

02 How does the Speedram 3 compare to the Speedram 2?

The Speedram 3 steps up from the Speedram 2 with a 150 mm spindle (vs 130 mm), 50 kW power (vs 37 kW), 1,000 mm quill travel (vs 800 mm), and larger travel ranges. The Speedram 3 is for the heaviest work that exceeds the Speedram 2's capacity, at a correspondingly higher price.

03 What kind of foundation does the Speedram 3 require?

The Speedram 3 requires a purpose-engineered reinforced concrete foundation designed for the specific machine and floor plate configuration. Foundation depths of 600-1,200 mm with heavy reinforcement are typical. PAMA provides detailed foundation specifications and often coordinates with the customer's civil engineering team.

04 Can the Speedram 3 perform milling operations?

Yes. Despite being classified as a boring mill, the Speedram 3's spindle speed range up to 2,500 RPM and 50 kW power make it capable of heavy face milling with large indexable cutters. The automatic facing head expands milling capability to 1,600 mm diameter. It is a boring-milling machine in practice.

05 How long does installation take?

Installation of a Speedram 3 typically takes 3-6 months from delivery to production, including foundation preparation, machine assembly, alignment, and commissioning. PAMA sends their own installation team for the critical alignment and commissioning phases.
