Punches for Camshafts

Punch machining

Punches are used to imprint a shape on a final part. By the very nature of the process, punches suffer significant levels of wear and so materials of extremely high hardness are needed.

In this case we machined the punch for a camshaft on the long-lasting Makino V33i. We cut 58 HRC steel and achieved the following:
 
  • Surface quality: Ra=25.62 nm
  • Geometric tolerance: ±0.003 mm

V33i

The V33i vertical machining centre incorporates a number of features specifically designed to increase precision and maintain it for the long periods of time typical of most die and mould applications. With X- and Z-axes on the spindle and Y-axis under the table, the machine construction provides superior performance in a compact package. Designed with no overhangs or unsupported areas, the V33i delivers outstanding accuracy over the full range of the machine. The guideways are integral to the machine castings to provide superior stiffness, rigidity and precision.
