Advanced Digital Readout System for Milling Machines and Lathes

The Magnescale LH70 is a high-performance digital readout (DRO) system designed for milling machines, lathes, drilling machines and general-purpose machine tools. Available in 1, 2 and 3-axis configurations, the LH70 combines intuitive operation with advanced machining functions, delivering improved productivity, reduced setup times and enhanced machining accuracy.

Designed to work seamlessly with Magnescale’s renowned magnetic scale systems, the LH70 provides exceptional reliability in harsh workshop environments where oil, coolant, dirt, vibration and shock can affect conventional measuring systems.

Possible successor to LH31A, LH52 or LH51 displays

Key features

Advanced Milling & Lathe Functions – The LH70 includes dedicated functions for both milling and turning applications, helping operators perform complex machining operations quickly and accurately.
Available in 1, 2 or 3 Axis Versions – Choose from single, dual or three-axis displays to suit your machine tool and application requirements.
High-Visibility LED Display – Bright 7-digit LED displays provide clear position information and excellent visibility on the shop floor.
Machine Error Compensation – Linear compensation functionality helps improve measurement accuracy by compensating for machine positioning errors.
Data Storage Protection – Displayed values and system settings are retained even after power interruption, minimising setup time and preventing loss of important information.
Reference Point Detection – Automatically detects scale reference points for reliable machine positioning and repeatable operation.
Programmable Machining Functions – Supports programmed machining operations with storage for up to 850 program steps

Benefits of the Magnescale LH70

Improves machining efficiency and operator productivity.
Reduces setup times through programmable functions and datum storage.
Increases machining accuracy and repeatability.
Resistant to oil, dirt, vibration and workshop contamination when used with Magnescale scales.
Simple integration with Magnescale SR138R (GB-ER), SJ700A and PL20C measuring systems.
Suitable for both retrofit and new machine installations. (This suitability follows from the LH70 being a counter compatible with multiple Magnescale scale systems; the sources do not explicitly discuss retrofit projects.)

Milling Machine Functions

The LH70 provides several dedicated machining functions for milling applications:

Bolt Hole Circle – Displays coordinates for equally spaced holes around a specified pitch circle diameter, simplifying circular hole patterns.

Line Hole Function – Calculates coordinates for equally spaced holes along a straight line.

Simple Radius Cutting – Provides coordinate calculations to assist with radius machining operations.

Multiple Datum Points – Store and recall multiple reference positions for faster setup and repeatability. The LH70 supports up to 10 datum points.

Lathe Functions

For turning applications, the LH70 includes dedicated lathe functionality designed to simplify common machining tasks and improve efficiency. Tool coordinate management and addition functions are available when the lathe mode is selected.

Compatible Magnescale Measuring Systems

The LH70 is compatible with:

Magnescale SR138R (GB-ER) precision magnetic scales.
Magnescale SJ700A magnetic scales.
Magnescale PL20C reader heads used with SL110 and SL130 magnetic tape systems.
