 |
Bore diameters as small as 0.1mm(100μm)can be attained when machining with the Namiki diamond micro-drill. |
|
Conventional machine tools can be employed with the micro-drill. Thus, higher speed, higher precision and lower cost can be obtained than by etching, electric discharge machining, or ultrasound machining. |
|
Work can be performed on a wide variety of materials, including ruby, sapphire, glass and ceramics. |
|
Since the diamond micro-drill produces exceedingly little friction, multiple-unit, continuous drill machining can be accomplished with limited dispersion of the work material.
