PAMA Speedram 2 vs PAMA Speedram 3
PAMA vs PAMA · CNC Boring Machines
Summary
The PAMA Speedram 2 and PAMA Speedram 3 are configurable boring machines from PAMA, both on the Siemens SINUMERIK 840D sl. The Speedram 3 is the larger model: X travel of 4,000 - 16,000+ mm against 3,000 - 10,000 mm, Y travel of 3,000 - 5,000 mm against 2,500 mm (98.4 in), and floor-plate loads of 100,000+ kg against up to 60,000 kg.
The Speedram 3 also has the stronger spindle, 50 kW (67 HP) against 37 kW (50 HP), and 80-160 tools against 60-120. The Speedram 2 is faster, at 5 - 3,000 RPM against 4 - 2,500 RPM, and lists tighter positioning: +/-0.008 mm per 1,000 mm against +/-0.010 mm per 1,000 mm.

Advantages
PAMA Speedram 2
- 3,000 RPM top spindle speed against 2,500 RPM
- +/-0.008 mm per 1,000 mm positioning against +/-0.010 mm per 1,000 mm
- Machine weight of 75 T against 80,000 - 200,000+ kg
PAMA Speedram 3
- X travel of 4,000 - 16,000+ mm against 3,000 - 10,000 mm
- Y travel of 3,000 - 5,000 mm against 2,500 mm (98.4 in)
- 50 kW (67 HP) spindle against 37 kW (50 HP)
- 100,000+ kg on floor plates against up to 60,000 kg
Verdict
The PAMA Speedram 3 is for the largest work: gas and steam turbine casings, marine engine blocks, rolling mill housings and mining equipment that need X travel beyond 10,000 mm or more than 60,000 kg on floor plates. The PAMA Speedram 2 suits energy, mining and job-shop castings within its configurable range, where its 3,000 RPM spindle and tighter positioning favor finishing.
