LAPMASTER WOLTERS has invested into further
development of the Abrasive Flow Machining (AFM)
for Free Form Honing (FFH).
The FFH Process utilizes an abrasive evenly dispersed
in a putty-like substance. The abrasive
media has the unique ability to take the shape
of any hole geometry. This process accomplishes
precision polishing, deburring & edge radius
generation and is especially designed for work
pieces which need a uniform polished surface, regardless
of their shape. The more difficult the id
shape is, the easier it is for AFM. Common polishing
and deburring machines were always limited
when facing odd shaped holes, very small holes
and cavities or edges. Due to the various types of
media that is available, holes as small as 0.008"
(0.203 mm) can now be machined effectively. Surface
finish generation as low as 4 μ” Ra is possible
and mostly determined by the type & size of
abrasive used. Conventional or super-abrasives
can be used.
LAPMASTER WOLTERS AFM is available in two
machine models/sizes with 6 different modes/
cylinder sizes and pressure ranges. Low costs per
part, and a very cost effective clamping-retaining
tooling. Another striking feature of the AFM is the
simple and fast tooling change-over for new parts
and its menu driven programmable system. The
cycle time depends on the material hardness and
pre-AFM surface finish to be removed.
This machine is made for several industries such as
Extrusion, Castings, Tool & Die, EDM Shops, Screw
Machine Shops, Valve Manufacturers, Gear Grinding
Facilities, Hydraulic and Medical Components,
Automotive, Aerospace and many more.
