The EZ-1250 high-frequency spindle was developed specifically for the requirements of the optics industry. It offers exceptional rotational accuracy and is suitable for all high-precision machining and finishing operations. The robust spindle is equipped with a pneumatic release unit that enables an automated tool change. The release unit and spindle are operated with a supply pressure of 5 bar. Due to the almost friction-free air bearing, heat generation is very low, yet the spindle is provided with connections for spindle cooling. With constant cooling and a suitable drive unit, the spindle can be operated at speeds of up to 80,000 rpm. The design of the spindle nose allows for long service life with minimal maintenance. Further versions of the tool holder and other collet sizes are available on request. Applications: Superfinishing, glass milling, wafer sawing, grinding of optical lenses and displays for cell phones & tablets, micro-machining of optical and medical products. In general: For applications with high demands on dynamics and precision.
