Attached to the toolhead
is the toolholding section.
It still features the same interchangeable toolhead
and quick-change shell plates.
This can be prevented using a factory-wide modular system with a special driven toolhead purchased for a previous application on another machine.
Because there is no modular base adapter loading, only one spare unit for each different driven toolhead is needed for all machines.
Modular driven toolheads have a neutral interface and are interchangeable to nearly any machine by using machine specific modular base adapters [ILLUSTRATION FOR FIGURE 2 OMITTED].
The actual tool change is simply a matter of unlocking a stud pin, something like a set screw, pulling the entire quick-change toolhead
off, and inserting the new preset tooling in 15 sec or less.
Next is the classic Sunray machine, Figure 4, in which both the work spindle and the toolhead
rotate to produce the Sunray pattern.
Some of the CNC machines they were using had robotic tool changers, and the factory has computer-tracked tools and toolheads
for inventory control.
Most modern presses have interchangeable toolheads
, and with other dies on a spare head it only takes minutes to change calibers.
In a chapter called "Watch Out For the Toolheads
," Seddon cautions managers not to be too dependent on the tools of TPS, reminding the reader that Ohno felt the approach was intuitive once the fundamental concepts were understood.
Italian firm Scaglia, which makes the toolheads
