It has been 20 years since Sodick, a pioneer in electrical discharge machines (EDM), launched the world's first electrical discharge machines to adopt a linear motor drive system.
Since then, we have shipped a cumulative total of more than 50,000 linear motor drive machines and they are known for their superiority around the world.
The AL40G and AL60G are a new generation of precision die-sinker EDM that are a fusion of linear motor control technology accumulated over 20 years, leading-edge discharge control technology, artificial intelligence (AI), IoT platforms, and temperature control systems.
Features
3-Axis (XYZ) Linear Motor Drive System
Accurate positioning and high-speed movement
The major features of our linear motors are their high speed and high response. These are achieved because of non-contact movement without a ball screw. Conventional drive systems use ball screws to convert rotary motion into linear motion. With this method, however, mechanical conversion errors adversely affect the tracking performance of the high-speed servo. Thanks to linear movement, there are no conversion errors from rotary motion in linear motors, and direct drive achieves accurate positioning and quiet, high-speed operation.
High performance linear motors developed and manufactured by Sodick
A high-thrust linear motor developed and manufactured by Sodick allows enhanced acceleration, deceleration and immediate stop at high speed and high response. Also, backlash is eliminated, which is impossible with conventional ball screw drive systems, and accurate axis movement is maintained accurate axis movement is maintained almost permanently.
High-rigidity Structure, Easy-to-use Design
In addition to highly rigid machine structure optimally designed with the latest CAE analysis technology, we have also improved the operator workability.
Since the three-sided automatic vertical machining tank moves up and down in conjunction with the machining fluid level, the workpiece being machined is highly visible. Because of the openness when the machining tank is lowered, the workpiece status can be checked from left and right, making preparation easy for complicated jobs.
The fluid level adjustment knob, jet suction adjustment knob, and the jet and suction pressure gauge are all arranged on the front side of the machining tank, enabling efficient setup work.
Total Temperature Control Function "TH COM"
TH COM (Thermal Commit), that precisely corrects the temperature of each component of the machine through sensing and provides various diagnostic functions, is installed as standard. It flexibly responds to temperature changes in the installation environment and minimizes thermal displacement during high-speed driving.
Newly Developed "SP Power Supply" Equipped with all the Latest Machining Circuits as Standard
The latest electric discharge control and electric discharge circuits improve the machining accuracy, machining speed, and machining quality across all the EDM processes from rough machining to semi-finishing and finishing.
New Stable Electrical Discharge System "Arc-less 4"
The development of the Arc-less 4 with “absolutely no arcing” that maintains stable discharge in all machining environments has dramatically improved die-sinker EDM performance, such as even higher EDM speeds, suppression of electrode wear to the utmost limit, and achieving a wide variety of machining surface finishes from satin to mirror finish.
LN Pro AI condition advisor uses AI to always provide the optimal machining conditions
The optimal machining conditions and NC program that achieves the desired machining status (machining shape, material, area, machining depth, machining speed, surface roughness, wear, etc.) are intelligently generated based on the built-in discharge fundamentals and the machining conditions.
This allows users from beginners to experts to fully exploit the machining performance.
Predictive Maintenance Gadget AIM
AI Maintenance (AIM) monitors and automatically diagnoses each status of the machine, including the operation status, maintenance status, and machine installation environment. This boosts the machine's operation rate, reduces machining defect rates and improves traceability.
