The Microgrind 2000XE is a fully automated 5-axis CNC Rotary Transfer Grinding Center for manufacturing micro drills, micro routers or micro endmils. This machine comes with an integrated robot loader and is equipped with a rotary transfer system, which three stations to work simultaneously. It is ideal for high volume production, with quick, simple machine setup and programming.

The Rotary Transfer System reduces cycle time by dividing the grinding process into 3 operations performed simultaneously. The control is able to manage 8 CNC axes (6 machine axes and 2 robot axes) and simultaneously interpolate 3 CNC axes. The grinding wheel shape can be calculated by using Rollomatic's FluteCalc software (optional) which provides accurate tool geometry and set-up parameters. A second control panel is located near the robot for fast and ergonomic set-up. 3 tool clamping and 2 tool support systems are integrated into the rotary transfer system.

The MicroGrind 2000XE provides the lowest cycle time obtainable for the manufacturing of endmills up to dia. 3.175mm (1/8").The CNC control is easy to operate and allows advanced features such as variable helix angle and web taper. Using the FluteCalc software (optional), the endmill flute geometry can be precisely designed by entering parameters like number of flutes, helix angle, core diameter, rake angle, land width and O.D. relief angle. A simple wheel with one or more angles can be used (with or without radius). The program then calculates the necessary parameters for wheel dressing and machine setup.

• Grinding range from Ø 0.2 - 3.175 mm
• Shank range from Ø 1.5 - 3.175 mm
• Overall blank length 30 - 50 mm
• Flute length 0 - 12 mm
• Helix angle 24 - 45°

Station 1
The two CNC axis robot loads blanks and unload finished tools. Three trays of 500 tools each, can be held of which two can be filled with blanks, giving the capacity to grind 1000 tools.

Station 2
The fluting and relieving is performed by clamping the tool shank in a V-block while guiding the fluted portion in a steady rest. The V-Shank guiding system guarantees a perfect run-out of the tool. The hydraulic movable and programmable steady rest can be used to minimize deflection allowing faster grinding feeds and better tool quality. The steady rest can be adjusted in multiple directions through micro-movements.

Station3
The shank is clamped in a high precision V guide. The programming is easy and allows all types of end-style to be made. The wheels are fine dressed and mounted on their respective spindles.
