Overview:

The AP650L Wire EDM features Sodick’s Linear Motor Technology. The AP Series is Sodick’s line of high end, high precision Wire EDM machines. The AP650L is available as an oil dielectric machine and features Sodick’s new Eco-Cut O technology. Using oil based technology, the AP250L is able to machine carbide and completely eliminate cobalt depletion. This machine offers low specific inductive capacity and a small discharge gap; this is ideal for high precision machining for high speed die applications. The carbide workpiece can be left in the work tank for long periods of time (which is ideal for a shop machining during nights or weekends).

Sodick’s AP650L flat rigid linear motor driven, high precision Wire EDM has improved cutting performance which is ideal for micro machining. The combination of the flat rigid linear motor drive system and bridge design has vast improvements in positioning and machining accuracy. It takes advantage of backlash-free precise axis movement, while minimizing the deformation of the machine structure. High levels of initial machining accuracy can be maintained for a long period of time. Sodick offers a 10-Year positioning accuracy guarantee 10-Year Positioning Accuracy Guarantee to ensure that customers can make sure of Sodick EDMs with a sense of security.

The AP650L Wire EDM features the newly developed SPW power supply unit and utilizes “Perfect Active Control” technology. It also uses 1 Gbit/sec serial communication technology featuring high-speed processing of the discharge control and motion control in a simultaneous process.

The AP Series features energy-saving designs and technologies. Compared to conventional EDMs, the Sodick Wire EDM Range can reduce average energy consumption by up to 60%.

Eco-Cut O is a newly developed technology by Sodick, and is now available on the AP650L. This technology enables the EDM to machine at incredible speeds using oil technology. Eco-Cut O allows the user to get the optimal surface finish of oil dielectric with the speeds of water dielectric – and faster. Eco-Cut O can increase machining speeds up to 12% over water dielectric and up to 25% over conventional oil dielectric. Eco-Cut O speeds up the cutting process due to the accuracy and surface finish being obtained at a faster pace requiring less cuts to be made to the part.

The new high speed, automatic, annealing wire threader improves wire straightness which increases the AWT repeatability especially at larger Z heights. During the annealing process, the wire is heated, stretched, and cut to a sharp point resulting in a smaller required wire guide clearance improving part accuracy. Since the annealing AWT can thread in the submerged mode, the worktank does not have to be drained when wire threading. The Z axis position will automatically set the dielectric fluid for the operator.

Cobalt depletion of carbide is eliminated when using oil dielectric, which is not possible with water dielectric, due to the corrosion and the electrolysis caused by water. A carbide workpiece can be left in the work tank for long periods of time (which is ideal for a shop machining during nights and weekends). With water dielectric, the workpiece has to be removed immediately when machining is completed or the water will cause corrosion. With oil, the gap between the wire and workpiece is smaller due to the lower intensity of the spark, which is ideal for precision machining for high speed die applications.

Through sensing, the temperature of each component of the machine is precisely corrected and the Thermal Commit (TH COM) function, which provides various diagnostic functions, minimizes thermal displacement due to temperature changes in the installation environment and during high-speed driving.
