Catalog - DIXI4 - Micro Machining Carbide Tools
It is called Micro Machining when a tool having inferior to 1 mm is involved, and manufacture micro tools requires discipline, experience, and ultra modern machining facilities enable the fabrication of these accurate and efficient micro cutting tools using the micrograin carbide size of which range below 0.5 to 1 micron absolutely necessary.
Tungsten carbide tools from 0.08 mm are manufactured and used in production.
Below 1 mm diameter, h6 tolerances for drills and h10 tolerances for end mills is unacceptable as it is too large, so our tolerances are 0/-0.004 mm for our drills and 0/-0.01 mm for our end mills. For special tools closer tolerances +0.001/-0.001 mm (+/- 1 micron) could be respected.
Drilling
For good chip removal in micro drilling, a surface finish of Ra 0.05 mm in the flute and Ra 0.015 mm on the cutting edges is absolutely necessary.
Our carbide drill start with 0.08 mm diameter for right hand and left hand cutting, straight or reinforced shanks are available.
The degressive helix drills guarantee to produce drilling depth of 10 x the cutting diameter and mainly used for horizontal drilling operations.
Boring and Micro Boring
The boring tools developed to enable to machine through and blind holes. Both solid carbide and those with hardened steel shank boring bars have been designed to give maximum rigidity and performance, enabling a considerable number of regrinds, offering long life and economical use.
Starting from diameter 0.5 mm up to 25 mm micro boring usually used on both lathes and jig boring machines to perform a constant profile even a particular cases such as deep holes and interrupted cuts.
High Performance Carbide Slitting Saws
The most important of these slitting cutters are keeping the symmetry, the surface quality of the flancs and the thickness tolerance to keep the dimension run-outs.
The solid carbide slitting saws supplied in coarse pitch, fine pitch, heller pitch, extra fine pitch and teeth according to DIN 1840 Bw.
The thickness starting from 0.12 mm up to 5.00 mm and the diameter from 15 - 20 - 25 - 30 - 40 - 50 - 63 - 80 - 100 - 125 - 160 mm.
We also could serve the solid tungsten carbide circular blades.
Thread Mills
The thread mills have been conceived for internal and/or external threading, enable threading in different sizes where only the pitch is maintained, manufactured with 2, 3, or 4 teeth depending on the diameter.
It is then possible to obtain with only one tool a standard thread, a fine thread as well as tolerances according to the user's requirement. And the application on CNC machining centres by helical interpolation operation.
For tapered threading, the programming is different to a cylindrical one since the tool must also describe a spiral along the taper. To obtain such a figure, a CNC machine able to move simultaneously 3 axes is necessary.
Micro Milling
DIXI 7032 - Ball end mill for Dies & Mould, general and micro machining
These cutters are used on machines allowing contouring operations where various surfaces can be produced. The manufacture of dies and punches need such tool since the pocket and moulds will be machined by means of displacement in the three dimensions. High speed milling operations (HSC) can also be achieved with this kind of end mill.

To calculate the width of cut (ae) use the formula 0.04 x D1, for the depth of cut (ap) all of the radius can be employed, with feed fz = 0.01 x D1 and the cutting speed = 25 to 110 m/min for conventional milling and cutting speed = 130 up to 700 m/min for high speed milling (HSC).
In order having any difficulties using the solid carbide, you could check on Trouble Shooting and for selecting cutting speed and feed rates on high speed milling (HSC), should be used our Cutting condition on HSC.
