(Click to see larger image) Narishige's EG-400 is the best unit we offer for high-precision grinding. The EG-400 is typically used for beveling glass microcapillary microinjection needles, yielding both a sharper needle and a larger opening. It can also be used for almost any fine polishing operation.

A "whetstone" grinding disk is spun by a stabilized variable-speed motor for either fast grinding or ultra-precision polishing. The EG-400 microgrinder includes a z-axis micromanipulator, a water dripping device to provide continuous lubrication and an integral microscope to monitor the grinding process.
