The PAMA ALC 127 NC fixed-column boring machine is a versatile, high-precision machine tool, highly regarded for machining large components. This model features a 127 mm diameter spindle with an ISO 50 connection, offering variable speeds between 2 and 1250 rpm thanks to a 4-speed gearbox. The 20 kW motor provides sufficient power for demanding machining operations, while the 3600 Nm torque allows for drilling and boring operations even on resistant materials.

The PAMA ALC 127 NC machine has a Z-axis spindle travel of 810 mm, a 300 mm axial spindle excursion, and a 1600 mm vertical head travel (Y-axis). Additionally, the table offers dual-axis movement, with a transverse (X-axis) travel of 2000 mm and a longitudinal (W-axis) travel of approximately 1272 mm, ideal for high-precision machining of large components. The table can support up to 36,000 kg, making it suitable for heavy industries, such as the aerospace and automotive sectors.

This boring machine, equipped with an ECS 2301 numerical control, allows for the automation of many operations, ensuring precision and speed in production processes. Rapid feed rates on the X, Y, and W axes reach 5000 mm/min, while feed rates on the Z spindle reach up to 3000 mm/min, significantly improving operating efficiency.

Accessories that can be combined with this boring machine include rotary tables for complex machining, special tools for boring and milling, and advanced measuring systems for checking dimensional tolerances. To achieve optimal operating parameters, the reference mathematical formulas include the calculation of the cutting speed (V = πDN/1000) and the power required based on the material being machined.

In terms of materials, the PAMA ALC 127 NC is ideal for machining steel, cast iron, and hard metal alloys, but can also be adapted to softer materials such as aluminum. Maintenance is essential to ensure the machine's longevity. In addition to regularly lubricating moving parts and checking gearbox oil levels, it's important to periodically check the linearity of the axes and the spindle's accuracy.

Buying a used machine like this, like the PAMA ALC 127 NC, can be very advantageous. PAMA machines are renowned for their robustness and longevity, so a used model can offer similar performance to a new one at a lower cost, making it an excellent choice for companies looking to save money without compromising on workmanship
