SR-38 type B
THE ADVANTAGES
In comparison to its proven smaller brother the SR-20R IV, the new SR-38 type B CNC automatic lathe has an extended material capability of 38 mm. Furthermore, balance cut machining can be carried out on the tool post (X3 axis). The swivel B axis offers additional machining possibilities.
