Sodick’s linear motors have a considerably higher dynamic performance than ball screw drives. The table and the motor constitute one unit – without any intermediate components as with recirculating ball screws, belts, pulleys or gears. All Sodick’s linear motors are developed and manufactured in-house. This has led to special arrangements of magnets, coils, and controllers to minimise, for example, cogging and torque ripple. This smooth drive system exhibits an exceptionally high dynamic responsiveness ideal for machine tools.

Sodick offers the possibility to fit additional axes as a factory option. Customers can choose from either Sodick’s own developed Rotary Table as an additional single A or B axis or a JauchSchmider Rotary Table as multiple axes for indexing or simultaneous contouring.

All Sodick machines operate with the control technology Sodick Motion Control (SMC) developed specifically for the linear drives from Sodick. The external features include maximum and logical ease of use. The internal SMC functions on the basis of a 64-bit multifunctional open system. The SMC directly monitors and automatically readjusts the linear motors - without any of the delays previously caused by the gap detector.

Ceramic has an extremely limited thermal displacement, and is a material indispensable for super precision machining. Sodick has a range of technologies to manufacture high-rigidity ceramics machine structural parts and hydrostatic ceramics bearing that make high-precision positioning possible. Sodick's self-manufactured ceramics provide electrical insulation essential in handling materials for electrical machines, in addition to such characteristics as being hard, light, and resistant to heat and wear.

Compared with conventional EDMs, the Sodick Die Sinker Range can reduce the average energy consumption by up to 60%. The newly developed power unit “LP” series efficiently supplies discharge energy and linear motor control current through the resistor free circuit. It has also become possible to save a great amount of total electric consumption as a result of a thorough review of peripheral devices.

Electrical Discharge Machining (or EDM) is a machining method used to machine any conductive materials including hard metals which are difficult to machine with traditional techniques. EDM can cut small or odd-shaped angles, intricate contours or cavities in pre-hardened steel without the need for heat treatment to soften and re-harden them.

In wire electrical discharge machining (WEDM), or wire-cut EDM, a thin single-strand metal wire is fed through the work piece, typically occurring while submerged in a tank of dielectric fluid. This process is used to cut plates and to make punches, tools, and dies from any conductive material, including hard metals, that are too difficult to machine with other methods.
