Engineering criteria for selecting DIXI micro-drills by workpiece material

Selecting DIXI Polytool solid carbide micro-drills depends on the physical properties of the workpiece alloy and the targeted aspect ratio.

For serial machining of watch plates and micro-electronic housings made of brass or nickel silver, DIXI 1131 R drills with reinforced DIN 1899 shanks provide maximum rigidity down to 0.1 mm diameters.

When drilling tough titanium alloys, austenitic stainless steels, or superalloys deeper than 3xD, self-centering 1345-5D-HH drills featuring Cool+ through-coolant channels are required to maintain continuous thermal control and chip clearance.

Milling hardened steels with DIXMILL variable helix solid carbide cutters

DIXMILL series DIXI 7242 and 7343 solid carbide end mills are engineered for finishing and semi-finishing mold and die steels of high hardness. The variable helix design effectively suppresses resonant chatter during high-speed 5-axis milling of steep cavity walls and deep slots.

Maintaining stable chip load per tooth combined with rigid hydraulic or shrink-fit toolholders delivers superior surface finish, reducing manual polishing cycles.

Achieving sub-micron IT5 and IT6 hole tolerances with precision reamers

DIXI 6100 solid carbide precision reamers with left-hand helix and right-hand cut ensure tight dimensional tolerances conforming to IT5 and IT6 standards with surface finish down to Ra 0.2 um.

The left-hand spiral geometry pushes chips forward ahead of the cut in through-holes, preventing scratch marks on the bore wall. Maintaining spindle runout below two microns during machine setup is essential to eliminate bell-mouthing.

High-speed composite and non-ferrous milling with PCD diamond tooling

DIXI 70600 PCD end mills and 70170 PCD engraving tools tipped with polycrystalline diamond are designed for burr-free machining of CFRP composites, silicon wafers, zirconia, and non-ferrous alloys.

Extreme diamond edge retention withstands abrasive carbon and glass fibers, completely preventing composite delamination and burr generation. High cutting speeds and sharp geometries minimize cutting forces and thermal distortion.

Synchronous thread whirling of micro-fasteners on Swiss-type lathes

DIXI 1737 full-profile thread whirling cutters and solid thread mills are designed for high-precision micro-thread generation from M0.8 on Swiss-type turning machines.

High-speed synchronized cutting produces external and internal threads on slender shafts without bending deflection, making them indispensable for surgical bone screws, dental titanium implants, and miniature watchmaking fasteners.
