Servo motor for processing machine of weldless method for square steel pipe columns.
CMS Series
Explanation of the non-welded joint method and labor-saving technology at construction sites. Servo motors that can be considered for the drive shafts of joint and steel pipe factory processing equipment.
In steel frame construction, the connection of square steel pipe columns has traditionally relied on "on-site welding" performed by skilled workers. However, a severe shortage of welders, delays in construction schedules due to weather, and the risks of discrepancies during high-altitude work have become significant challenges in the construction industry. As a solution, the "on-site non-welding joint method," represented by column couplers, is gaining popularity. By eliminating arc welding work on-site and replacing it with mechanical connections using bolts, consistent construction quality can be ensured regardless of weather conditions and without the need for specialized skills. Safety is also improved since no open flames are used, and significant reductions in construction time are expected. However, to facilitate smooth non-welding connections on-site, it is essential to perform highly precise dimensional processing (cutting, drilling, etc.) on joint components and steel materials during the factory production stage. The "AC Servo Motor (CMS Series)" that we handle is a motor that can be considered as a driving axis for precision processing machines and automation lines for construction steel materials, fundamentally supporting such non-welding methods.

basic information
■ Technical Points of Square Steel Pipe Columns and Non-Welded Joint Method - Shortened Construction Period and Safety: By eliminating the use of fire on-site, the burden of safety management is reduced, allowing for planned construction that is not dependent on weather conditions. - Prefabrication and Processing Accuracy: To ensure accurate coupling and bolting on-site without discrepancies, strict requirements for hole drilling precision in millimeters, as well as the perpendicularity and flatness of components, must be met during primary processing in the factory. ■ Structural Features of AC Servo Motors for Steel Processing Equipment (CMS Series) - High-Precision Positioning Control: Utilizing feedback from encoders, it can be applied to the accurate feeding mechanism (positioning) of long and heavy steel pipe columns and joint components. - Rigidity and Responsiveness: It can be incorporated into the design of automated equipment that supplies stable torque even against large load fluctuations occurring during cutting and drilling processes. - We conduct domestic inspections for prototypes and small lots before delivery.
