EWS Enhances BMT65 Tool Performance with New Flexible Coupling

written by Bernard Martin
​

EWS announced some significant enhancements to their BMT65 tool lineup. All BMT65 tools are now equipped with a new flexible coupling and EWS.Techline, aiming to boost performance and service life. 

The flexible coupling is designed to compensate for misalignment, allowing a maximum radial offset of 0.3 mm between the driven tool and the machine drive. Its mechanism operates similarly to the Oldham principle, with the coupling joint swiveling in one axis and sliding into the groove of the drive in the second plane. Additionally, an elastomer support ring is incorporated to reduce vibrations and noise, contributing to a more efficient and quieter operation.

EWS.TechLine in detial

EWS.TechLine is a suite of advanced technologies integrated into EWS's tooling systems to enhance performance, durability, and efficiency. This comprehensive package includes several key innovations including:

• EWS.HPC-Line -  A ceramic-based sealing technology capable of handling coolant pressures up to 70 bar at speeds up to 12,000 rpm, with unrestricted dry-running capability. 
• EWS.Polygon-Joint -  A polygonal shaft-hub connection that allows for up to 30% more torque transmission compared to traditional connections, enhancing impact and fracture resistance. 
• EWS.Butterfly-Seal -  A revolutionary sealing technology featuring a triad of front labyrinth, special sealing elastomer, and preload ring, providing maximum protection against coolant and particle ingress while reducing operating temperatures by up to 50%. 
• EWS.Coolant Management - A universal system that allows for easy adjustment of external coolant outlets, enabling individual flow adjustments with just one turn, available in both axial and radial versions.
  
  

By incorporating these technologies, EWS.TechLine aims to provide machinists with tooling solutions that offer superior performance, reliability, and ease of maintenance.
