Sandvik Coromant Quick Change for CNC Lathes - Manual (Page 6)

1. Reduced batch change over time using tooling kits
Quicker tool changing
- External turning (5 to 10 mins)
this increases when using shank tools with high pressure
coolant.
- Internal turning (5 to 15 mins)
with boring bars it takes longer time than a shank tool with
center height and internal coolant setting.
- Driven tool holders (5 to 20 mins)
standard driven tools are either ER collets or face milling.
ER has a limited tool diameter allowing only end milling
(max dia 25 with ER40). This means either low productivity
or 2 separate driven units are needed which increases the
setting time and investment.
Key benefits -
Quick change versus shank and conventional ER
driven units
Increase machine utilization –
