Dynomax’s Dynogrind spindle series is designed for robotic grinding of abrasive materials such as glass, ceramic, composite and forged materials for the aerospace, automotive, renewable energy and robotics industries. The spindles employ the company’s Dynoguard technology, which is designed to protect against abrasive environments. The sealing system increases spindle life and reduces the frequency of replacing machine housings commonly destroyed by the abrasive spray, the company says.
With a maximum speed of 18,000 rpm, the spindle series is designed for a variety of applications. The HSE070-812289 model weighs 33 lbs (15 kg) and provides 8.5 hp at S1 duty and 12,000 rpm. The spindle generates 3.8 foot-pounds of torque.
The spindles are equipped with a complete abrasive grinding package. The standard HSK tool-change system enables quick tool change to increase productivity and accuracy, especially at higher speeds, the company says. An optional automatic system is suited for closed-cell machining and further reduces the time required for tool changes. The custom tool adapter increases accuracy when a high-precision tolerance is required. The tool adapter also changes grinding disks quickly and can spin in both directions to increase versatility.
The industry standard power management/interconnect system provides complete protection from the slurry, dust, water and other invasive materials present during abrasive grinding applications, the company says.
