The brand new die sinkers present improved machining accuracy, velocity and high quality, from roughing and semi-finishing by means of to ending, on account of a spread of recent applied sciences together with the most recent EDM controls and electrical discharge circuits.

As well as, the machines profit from a extremely inflexible construction, with temperature sensors put in all through the machine physique, to minimise the impact of temperature modifications throughout excessive velocity machining.

Massive, easy-to-operate,19-inch contact panels come as customary, whereas the LN Skilled Synthetic Intelligence program ensures perfect machining situations always, enabling the AL40G and AL60G to be operated optimally by each newbies and consultants alike.

Ease of entry is offered by the three-sided, automated, vertical drop machining tank, which allows the incorporation of all kinds of automation applied sciences.

Superior machine design plus linear motors

These machines are geared up on the XYZ axes with Sodick’s high-output linear motors, offering wonderful machining efficiency and sustaining excessive accuracy over lengthy intervals of time. The linear motors are pushed by the newly developed SP energy provide which allows extremely correct positioning and likewise doubles servo responsiveness in comparison with standard know-how.

The extraordinarily inflexible machine construction was optimally designed utilizing state-of-the-art CAE evaluation know-how, whereas the incorporation of a brand new precision correction perform, “TH COM”, minimises the impact of temperature modifications throughout the machine, decreasing the quantity of thermal displacement by 50 % in comparison with a traditional machine.

Linear bounce and ceramic slider

The brand new AL40G/AL60G collection is provided with Sodick’s independently developed light-weight, excessive rigidity ceramic sliders with low thermal displacement for the slide portion of the primary spindle linear motor. The mixed impact of this along with the excessive velocity, dynamically responsive linear motor ends in enormously improved straightness and a clean drive, considerably contributing to elevated velocity and the secure machining of deep ribs. The high-speed bounce successfully discharges machined ideas, decreasing irregular arcs and the machining form defects attributed to secondary discharge, thus enormously decreasing the machining time.

Secure electrical discharge system “SGF4”

The incorporation of Sodick’s “SGF4” superior electrical discharge management know-how through which an “arc by no means happens”, enormously improves die-sinking efficiency, rising velocity, decreasing electrode put on and enabling an intensive vary of machined floor qualities from satin to reflect surfaces to be obtained, by optimising the slicing applied sciences routinely.

Optimised, excessive velocity, excessive precision machining is achieved by the mixture of built-in applied sciences together with; discharge state detection, discharge pulse management and dynamically responsive linear motor know-how.

New SP energy provide improves machining efficiency

The brand new SP energy provide greater than doubles motor management response velocity, whereas the standard and velocity {of electrical} discharge machining general have benefited from the event of recent controls and circuits, together with: as much as 50 % extra slicing voltage on tough slicing (TMM4 circuit), elevated semi-finishing velocity (TPC4 management) and improved high quality and velocity of the ending minimize by means of correct pulse management (BSN4 circuit).


In response to the rising demand for automated methods, the brand new AL40G/AL60G collection has been designed to help a wide range of automation options. The brand new fashions incorporate a three-sided automated vertical drop machining tank and suspended operation panel, in order that automation know-how, from a easy automated software changer to a full-scale robotic automation system, will be put in.

Synthetic Intelligence and extra

Extra advantages of the brand new collection embrace Sodick’s “LN Skilled AI,” which provides a variety of relevant slicing patterns to go well with varied machining necessities. For every machining sample, optimum machining situations and axis motions can be found and NC applications are routinely generated by the AI database.

Software program, included as customary, allows the SP energy provide unit to immediately and precisely import 3D strong mannequin information, so positioning data will be enter from the machining instruction by merely clicking the mouse on the strong mannequin displayed on the operation display screen, stopping human errors and enormously rising operational effectivity.

Data from the AL40G/AL60G slicing applied sciences database is appropriate with the brand new machines, to which the AL-G collection provides an additional new know-how database with new generator options (not appropriate with earlier fashions).

Eco, vitality saving, safety and security

One of many prime issues within the design of the AL40G / AL60G was the event of an energy-saving, recycle/reuse, people-friendly, waste discount and upkeep free eco-friendly machine software — in-line with Sodick’s international coverage of working to constantly enhance its environmental impression ,which is central to the corporate’s improvement imaginative and prescient.
