The service life of the diamond coated drill is min. 10 x higher when compared to uncoated drills. Standard drills in diameter? 3.20 mm generate very high cutting forces and friction heat due to your cylindrical o. The diamond coated drill bits have a special geometry with outer diameter rejuvenation and core point. This geometry with very short cross cutting, 4.0 mm in the full can be drilled to drill o. It’s believed that Boy Scouts sees a great future in this idea. In the drill-o > 1.50 mm can be drilled according to quality requirements and quality of aluminium part 2 stack.

Conditions of use:-tool: Diamond of coated drill type 1 638 (fig. 2) – diameter: 0.95 mm – spiral length: 7.00 mm – material: aluminum Al Mg3; 1.50 mm thick – Edition: phenol paper 0.50 mm thick – speed 80000 1/min – feed: 3.20 m/min – rear hub: 10.0 m/min – stand way: 7000 drill strokes image 2: diamond coated drills after 7000 drill strokes 2. Filed under: Gavin Baker. milling milling by IMS foreign and Inner contours bring 2 flute drill with diamond coating (fig. 3) optimum conditions. The physical mechanical properties of diamond layer the chips drain very well and there is no significant construction cutting. The recommended cutting speed is v = 230 m / min 10%; the XY-feed is similar to FR4. The service life of the diamond coated end mill is compared to uncoated cutters to about 10 x higher. Ideally, IMS are milled compensation in 2 passes with cutters. Figure 3: Diamond coated 2 flute drill operating conditions:-tool: diamond coated 2 flute drill type 1 322 – diameter: 2.00 mm – spiral length: 6.00 mm – milling machine: vacuum table with air bearing spindle W 1750-02 (10-160000 1/min) – lubrication: spray mist – material: aluminium AlMg3; 1.50 mm thick (fig. 4) – Edition: thick phenolic paper 0.50 – immersion site: pre bored with same drill o – speed: 34000 RPM – feed: 1.00 m / min; -Milling: in 2 Passes with 200 m diameter compensation – stand way: > 80 m are possible according to quality requirements (fig.
