SE 1020 Numeric service

SE 1020 Numeric service is provided for the CNC universal center lathe originally manufactured by TOS / TRENS Trenčín, designed for heavy‑duty machining of rotational components with a maximum swing diameter of up to 1020 mm. The SE 1020 NUMERIC is intended for technologically demanding applications where rigidity, machining stability and long‑term accuracy when working with large workpieces are essential.

Although production of the SE 1020 NUMERIC has been discontinued, we continue to provide complete service, spare parts supply, technical support and modernization options to ensure safe and reliable long‑term operation under current manufacturing conditions.

Characteristics of the SE 1020 NUMERIC Lathe

The SE 1020 NUMERIC belongs to the category of CNC universal center lathes and is designed for machining bar stock, forgings and cut material. By combining turning operations with drilling and milling capabilities, it enables production of geometrically complex and dimensionally demanding workpieces within a single working area.

The machine is widely used for specialized turning operations in the gas, oil and water management industries, where extremely high demands are placed on accuracy, safety and operational reliability.

Machine Design and Heavy‑Duty Machining Capability

The SE 1020 NUMERIC is designed with a strong emphasis on long‑term rigidity and stability for heavy‑duty machining. Key machine components are stress‑relieved by annealing, ensuring permanent geometric stability and consistent accuracy throughout the machine’s service life.

A spindle headstock with a two‑stage gearbox enables efficient machining of large‑diameter workpieces while maintaining sufficient torque. Automatic gear shifting directly within CNC cycles improves operator comfort and overall operational efficiency.

Accuracy, Measuring Systems and Operational Reliability

The machine is equipped with direct spindle position measurement, ensuring high machining accuracy even during eccentric machining of large diameters. The use of bearings with lifetime grease lubrication contributes to low operating costs and high long‑term reliability.

Thanks to its robust construction and well‑engineered technical design, the SE 1020 NUMERIC is suitable for continuous operation in demanding industrial environments.

Operation, Safety and Configuration Flexibility

The SE 1020 NUMERIC is an ideal solution for users transitioning from a conventional universal lathe to a CNC‑controlled machine. It offers comfortable operation, intuitive controls and a high level of operator safety.

The machine is equipped with protective enclosures featuring reinforced safety zones. A wide range of configuration options allows precise adaptation to technological requirements, including:

hydraulic workpiece clamping,
hydraulically operated tailstock,
driven tools,
tilting C‑axis,
wide range of turning lengths,
extensive selection of steadies and clamping plates.

SE 1020 Numeric Service and Spare Parts

Even though the SE 1020 NUMERIC is no longer in production, we provide comprehensive SE 1020 Numeric service, including:

service of mechanical, electrical and CNC components,
supply of SE 1020 NUMERIC spare parts,
repair and overhaul of headstocks, gearboxes and drive systems,
service of measuring systems and sensors,
fault diagnostics and technical audits,
preventive and scheduled maintenance.

If original components are no longer available, we propose technically equivalent replacement solutions that preserve machining accuracy, operational safety and machine lifetime.
