SCT275/120/160/380 Flat-bed CNC Double Head Lathe

Double-sided simultaneous machining in one setup delivers far higher concentricity than conventional single-head lathes.
Minimal deformation for slender shafts, perfectly suited for rod and pipe parts.
Low vibration and lasting accuracy, ideal for mass assembly line production.
Easy commissioning and fast workpiece replacement, reducing overall production costs.

PRODUCT INTRODUCTION 

Introduction

The flat-bed lathe is one of the most traditional and widely used metal-cutting machine tools. Its bed features a horizontal guideway layout, offering a simple yet robust structure that provides excellent rigidity and stability. This machine is designed for turning a wide variety of rotational parts, including external and internal cylindrical surfaces, end faces, grooves, chamfers, and both metric and inch threads. It is extensively used in general engineering workshops, automotive parts manufacturing, mold making, and equipment maintenance.

The flat-bed design offers strong load‑bearing capacity and high stability, making it particularly suitable for processing long shafts, large disc‑type components, and heavy workpieces. The bed is constructed from a one‑piece high‑strength cast iron, with guideways that are induction‑hardened and precision‑ground for outstanding wear resistance and long‑term accuracy retention. The spindle system is rigid and offers a broad speed range to adapt to different materials and cutting conditions.


Features

High Rigidity and Load Capacity – The integral cast iron bed with wide guideways provides a stable foundation for heavy‑duty cutting and large workpiece machining.

Wide Range of Operations – Capable of turning cylindrical and tapered surfaces, facing, grooving, boring, drilling, and cutting various thread types, offering excellent versatility.

Easy Operation and Maintenance – Controls are logically arranged for intuitive use; the guideways are highly wear‑resistant, requiring minimal maintenance over extended service life.

Stable and Reliable Accuracy – Precision‑ground, induction‑hardened guideways combined with high‑quality spindle bearings ensure consistent accuracy over long periods.

Flexible Configuration – Optional accessories such as digital readouts, hydraulic chucks, steady rests, and follow rests are available to meet diverse processing requirements.
