Horizontal gap-bed lathe machine, Heavy-Duty Lathe, Swing dia. 940mm, Different turning length 750-10000mm, Spindle bore 110mm - details see: https://www.machineto.com/al-940b-horizontal-gap-bed-lathe-machine-universal-lathe-10128078

Gap-bed Lathe Machine

These gap bed lathes are suitable mainly for turning internal and external cylindrical, conical and other swing surfaces as well as various metric, inch module and diametric pitch threads. They can also be used for broaching oil grooves and keyways.

Features:

1. The side wall of bed is constructed with double-rib plates, and the shape of internal ribs is of box type and bevel ribs combination.

2. On apron, there is a device operated by a single lever, used for rapid traverse of the carriage.

Spindle’s braking and rotating direction change is controllled by hydraulic system, or by hand operation according to your choice.

3. The saddle guideway is glued by “TSF” soft belt wear resisting materials.

4. We can equip the lathe with automatic feeding mechanism.

The top slid can be used independently for turning short cone, or in combination with longitudinal feeding turing long taper surface.
