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

The PAMA ALC 127 NC machine has a spindle travel on the Z axis of 810 mm, an axial spindle travel of 300 mm and a vertical head travel of 1600 mm (Y axis). Furthermore, the table offers movements on two axes, with a transverse (X-axis) of 2000 mm and longitudinal (W-axis) of approximately 1272 mm, ideal for highly precise machining of large components. The table can support up to 36,000 kg, making it suitable for heavy industry, such as aerospace or automotive.

This boring machine, being equipped with an ECS 2301 numerical control, allows you to automate most of the operations, guaranteeing precision and speed in the production processes. Fast feeds on the

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

In terms of materials, the PAMA ALC 127 NC is ideal for processing steel, cast iron and hard metal alloys, but can also be adapted to softer materials such as aluminium. Maintenance is essential to ensure the longevity of the machine. In addition to regular lubrication of moving components and checking oil levels in the gearbox, it is important to periodically check the linearity of the axes and the precision of the spindle.

Buying a used vehicle of this type, such as the PAMA ALC 127 NC, can be very advantageous. PAMA machines are renowned for their robustness and longevity, so a used version 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 the quality of workmanship​
