Abrasive Flow Machining is a surface finishing process that is
used extensively since a long time in the Extrusion Industry.
It is
used for Polishing new Dies and for Reconditioning of used
Dies.
Abrasive Flow Machining uses a viscous, abrasive-laden Media that is
flowed, under pressure, back and forth through a Die in a Machine
Tool. The Die is often clamped directly between the two Media
cylinders in the machine but sometimes Adaptor Plates are used also.
Micro Technica® Technologies specializes in various Surface
Finishing Technologies for polishing, deburring and edge-contouring.
We developed MicroStream® Process, also called Advanced Abrasive
Flow machining (AAFM) and their expertise has been used in
applications for Surface finishing, deburring and polishing in
medical, automotive, hydraulic, textile, die and mould industries.
An Extrusion company can have more than 1000 dies in their Die-shop;
all of them unique. In order to polishing dies some companies use
the “old” form of Surface finishing Machining but this lacks process
control. Because it is not possible to regulate the Abrasive Media
flow-speed accurately some Dies which are polished using this method
have excessive
edge-radii or insufficient polishing of the Bearing. This leads to
manual intervention, which is undesirable.
The MicroStream® Surface finishing Machining with the IPC system is
a Polishing Tool which gives 100% repeatability with the best
result, by utilising optimum Media flow speed for each Die
polishing.
