Easson ES-14B Constant Speed Lathe 3 Axis Digital Readout System

Product Introduction

The Easson ES-14B Constant Speed Lathe Digital Readout System is a professional LCD DRO designed specifically for precision lathe machining applications.

Unlike traditional digital readouts that only display axis position, the ES-14B integrates spindle speed control, linear surface cutting speed monitoring, and encoder feedback, allowing the operator to maintain optimal machining conditions during turning operations.

The system supports constant surface speed (CSS) control, enabling the spindle speed to automatically adjust according to the workpiece diameter during machining. This ensures that the cutting speed remains constant, improving surface finish quality and tool life.

The ES-14B DRO outputs a 0–10V control signal to the spindle inverter, allowing direct regulation of spindle rotational speed for both automatic and manual control modes.

With its intelligent lathe-specific functions such as Z-axis summing, tool offset memory, and radius/diameter display switching, the ES-14B significantly improves machining efficiency and reduces operator errors.

Designed for industrial environments, the DRO system complies with international EMC standards, ensuring reliable operation in machine tool workshops.

Key Features

Constant Surface Speed Control (CSS)

The ES-14B digital readout system automatically adjusts spindle speed based on the current X-axis diameter to maintain a constant cutting speed during turning operations.

This feature improves:

• machining efficiency

• cutting stability

• tool life

• surface finish quality

Major Function Keys & Buttons

Automatic and Manual RPM Control

The DRO provides two spindle control modes:

AUTO RPM Mode

The spindle speed is automatically controlled according to the preset linear surface cutting speed.

MANUAL RPM Mode

The spindle speed is controlled using the DRO’s speed adjustment knob.

This flexible control system allows operators to choose the most suitable operating mode depending on the machining task.

0–10V Spindle Inverter Control

The ES-14B outputs a 0-10V analog control signal directly to the spindle inverter, enabling precise electronic control of spindle speed.

This allows seamless integration with modern lathe drive systems.

Linear Surface Cutting Speed Display

The DRO directly displays the linear cutting speed (m/min) during machining, enabling operators to monitor cutting conditions in real time.

Z and Z1 Axis Summing Function

For large lathes equipped with two longitudinal scales, the ES-14B supports axis summing, allowing the Z and Z1 axis readings to be combined and displayed as a single value.

This improves tool positioning accuracy.

Applications

The ES-14B Constant Speed DRO system is widely used in:

• precision lathe machining

• metal cutting workshops

• mold manufacturing

• automotive component machining

• aerospace component turning

• general mechanical manufacturing
