The ablation hap-pens on the outer track of the circular beam path, similar to a mechanical mill. It also enables an inclination of the laser beam to the sample surface by

The Micro Mill is a very rigid and precise machine that uses some of the most advanced techniques compared to its competitors. The Y-axis and Z-axis are supported on 2 1/2 inch square steel tubing to provide a very solid feel. The leadscrews are all 1/2-20 unlike a lot of machines of similar size that use 1/4 inch leadscrews.

must have enough clearance to minimize heat build -up. Triple chip blades 2.5 -3.5 teeth per inch are suggested. We have good results with .035" thick x 1" wide blades. Generally, fewer teeth per inch than metals require will help reduce heat build-up. We suggest 3 teeth per inch at a band saw speed of 2500 ft per minute as a starting point.
