ACER ATB 77 CNC LATHES

Technical Description

This CNC lathe machine features a **2-axis control system** operating along the X and Z linear axes, enabling precise turning operations by controlling diameter (X-axis) and length (Z-axis) movements. It is powered by a robust **37.3 kW motor** delivering high torque and efficient cutting performance. The spindle achieves a **maximum speed of 250 RPM**, suitable for machining large and heavy workpieces requiring strong force rather than high-speed cutting. The machine accommodates a **maximum swing diameter of 77.17 inches**, allowing for the turning of substantial diameter components. Equipped with a **tailstock**, it supports longer workpieces securely from both ends during machining, improving stability and precision. Control is managed via a **CNC system**, which enables automated, programmable machining with enhanced accuracy and repeatability. Typical applications include turning of large cylindrical parts for industries such as heavy machinery or aerospace. The machine likely features precision ball screws and servo-driven axes to ensure smooth, accurate tool movement. This setup is ideal for manufacturing large, symmetrical parts with moderate complexity where high rigidity and power are required rather than ultra-high spindle speeds or multi-axis tool paths. The 2-axis CNC lathe balances power, size capacity, and control sophistication for cost-effective production of substantial workpieces with consistent quality.
