New release 5-2021: The HELITRONIC MICRO tool grinding machine produces and sharpens rotationally symmetrical tools and production parts with smaller diameters. It grinds tools from a diameter of 0.1 mm in production and in re-sharpening operation from a diameter of 3 mm. The maximum diameter is 12.7 mm, the tool length is now up to 220 mm and the piece weight is up to 12 kg.

Tried pcb drilling at 15v it done good.1mm, 0.8mm and 0.3mm drill they provide(no 0.7mm drill). 0.3mm is waste it get easily broken. Low quality plastic case.

Grinding wheel dressing. The dressing of the grinding wheel is usually divided into two processes: shaping and sharpening. Shaping is to change the macro shape of the grinding wheel to make the grinding wheel reach the required geometric shape and dimensional accuracy, and to make the tip of the abrasive particles finely crushed to form a sharp sharp edge.

The general manufacturing processes of micro-drill with planar drill point are shown in Fig. 3. Step 1: Cut a round rod to an appropriate length.Step 2: By the way of centerless grinding, grind the round rod to be in the diameter size of the shank of micro-drill.Step 3: Grind the round rod to be a drilling part with drill rod and shank.In order to decrease friction between auxiliary flank and ...
