The reconditioning of cylinder heads, and valve
seats in particular, is becoming an increasingly
important aspect of internal combustion engine
overhaul work.
The fiel of cylinder head and
block reconditioning there has been a growing
tendency in recent years to switch from grinding with
abrasive sectors to milling, using special CBN and
PCD round inserts that are able to work at higher
cutting speeds and without coolants.
This kind of system reduces machining times
considerably, whilst at the same time guaranteeing a
high-grade surface finish (roughness).
In the design and construction of this product,
BERCO, as always, has paid great attention to the
quality of the materials and components used, with
particular reference to the very sturdy cast iron
frame and the worktable and head movement
mechanisms with their high-precision recirculating
ball screws, which, thanks also to the special drives,
powered by direct current motors, allow extremely
precise worktable/workpiece feed speed setting and
milling cutter positioning.
In order to cater for varying user needs, BERCO has made two machine versions, the “1000” and the “1300”:
-
SM 1000 M - SM 1300 M (manual versions)
- SM 1000 A - SM 1300 A (automatic versions)
