The reconditioning of cylinder heads, and valve
seats in particular, is becoming an increasingly
important aspect of internal combustion engine
overhaul work.
A number of changes have been made to the new
ASV/B model, the version intended for the smallmedium
sized cylinder head range. The quill
diameter has been enlarged to increase the
machine’s rigidity and, on request, a micrometric
spindle feed device can be fitted to improve
machining precision on the valve seats.
As regards larger size diesel engines, continuous
technological evolution has led to the manufacture
of cylinder heads with four valves per cylinder as a
standard feature, with a corresponding increase in
the size of the cylinder heads themselves.
The answer to the problems related to this can be
found in the new ASV/BL valve seat boring machine.
