SE 320 Numeric service

SE 320 Numeric service is provided for the CNC universal center lathe originally manufactured by TOS / TRENS Trenčín, designed primarily for single-piece, small‑batch and medium‑batch production of smaller components. Thanks to its machine concept, the SE 320 NUMERIC is suitable both for conventional production and for operations where flexibility, ease of use and stable machining accuracy are required.

Although production of the SE 320 NUMERIC has been discontinued (approximately at the turn of the 1990s and early 2000s, depending on version), we continue to provide complete service, spare parts, technical support and modernization options to ensure reliable long‑term operation under current manufacturing conditions.

Characteristics of the SE 320 NUMERIC lathe

The SE 320 NUMERIC belongs to the category of CNC universal center lathes and is widely used for machining simple as well as more complex flange‑type and shaft‑type workpieces made of metal or plastic materials. Thanks to its versatility, the machine is suitable for both one‑off production and small to medium production series.

The machine is also frequently used as a training and educational lathe at secondary schools and universities with a technical focus, where it enables a smooth transition from conventional turning to CNC machining technology.

Manual and automatic CNC operation

A major advantage of the SE 320 NUMERIC is its ability to operate in two modes:

manual turning using electronic handwheels,
automatic machining in CNC cycles via the control system.

This combination is particularly beneficial in single‑piece and small‑batch production, where rapid response to changing orders is required while maintaining high productivity and machining accuracy.

Machine design and machining accuracy

The SE 320 NUMERIC is designed with an emphasis on long service life and operational stability. Key machine components are stress‑relieved by annealing, ensuring long‑term preservation of geometric accuracy throughout the machine’s lifetime.

Belt‑driven spindle transmission significantly reduces vibration transfer, contributing to excellent surface quality of machined workpieces. The use of bearings with lifetime grease lubrication results in low maintenance requirements and reduced operating costs.

Operation, installation and safety

The SE 320 NUMERIC is an ideal solution for users transitioning from a conventional manual lathe to CNC technology. It offers:

simple and comfortable operation,
clear and intuitive controls,
compact footprint suitable even for smaller workshops.

The machine is equipped with protective enclosures featuring reinforced safety zones, providing a high level of operator protection while maintaining good accessibility to the working area.

SE 320 Numeric service and spare parts

Even though the SE 320 NUMERIC is no longer in production, we provide comprehensive SE 320 Numeric service, including:

service of mechanical, electrical and CNC components,
supply of SE 320 NUMERIC spare parts (original and alternative),
spindle and drive repairs and adjustments,
CNC control system service and diagnostics,
machine inspections and technical audits,
preventive and scheduled maintenance.

If availability of original components is limited, we propose technically equivalent replacement solutions with a focus on safety, accuracy and long service life.
