The electronic beam welding machine from Germany's SST (Steigerwald) company is a device capable of stably irradiating high-voltage electron beams of up to 150KV. With irradiation at high voltage, it can achieve narrow and deep penetration while minimizing deformation due to heat input. Additionally, because the beam is stable, the spike depth on the workpiece is also consistent and reliable. Furthermore, with multi-beam technology, it can perform "preheating," "main welding," and "cosmetic welding" simultaneously with a single beam. It is suitable for welding many metals, including aluminum, copper, and dissimilar metal joints. *For more details, please refer to the PDF document or feel free to contact us.*

Rough surface processing (laser roughening) is equipment that performs rough surface processing inside engine bores using lasers. This is done to enhance the adhesion between the base material and the thermal spray material. By creating a special profile shape on the inner surface of the bore with a laser, it not only generates a higher adhesion compared to conventional mechanical roughening but also allows for a shallower depth of the roughening profile. This not only reduces the cycle time for thermal spraying but also significantly decreases the amount of thermal spray material used. 【Features】 ■ By configuring the equipment in a two-axis structure, simultaneous processing of #1 bore and #3 bore, as well as #2 bore and #4 bore, is possible.

The MEBW60 series is an electron beam processing machine specialized in extremely fine machining. It excels in processing materials that are difficult to work with using laser machining. Welding: It achieves high-precision welding with a welding width of less than 1mm, such as 200μm. Depending on the conditions, welding with a width of 50μm is also possible. The output is 60KV with a maximum of 33mA. Drilling: It can create extremely small holes of less than 50μm in metal due to localized strong energy. Depending on the conditions, drilling holes of 10μm is also possible. Metal surface processing: It is also capable of surface structure formation, hardening, engraving, and polishing.

ALFING GmbH in Germany has long been a leading manufacturer in the market for production equipment for connecting rods. Many manufacturing technologies, such as cracked connecting rods, were first mass-produced using ALFING machines. This technology is also applied to other components, such as crankshaft bearing caps or disc cams. **Features** Cracking of Connecting Rods A fracture initiation surface is created on the inner surface of the large end of the integrally formed connecting rod using laser light or machining, and it fractures under impact load. During reassembly, the fracture surfaces are aligned and tightened. Since shear loads are borne across the entire large fracture surface, the strength is significantly increased compared to the conventional reamer bolt method. Moreover, the need for high-precision finishing of bolt holes is eliminated, allowing the process to be consolidated to less than two-thirds, achieving significant cost reductions. Cracking of Bearing Caps Five bearing caps, integrally cast as a whole block, are simultaneously fractured. The cracking process is similar to that of connecting rods, resulting in significant strength improvements and cost reductions.
