Horn USA's W&F Linear Unit Quick-Change System Improves Tool Change Repeatability
IMTS Spark: The W&F linear unit with coolant management from Horn USA is a user-friendly quick-change system that can be combined with W&F Micro quick-change holders and existing standard holders.
The W&F linear unit with coolant management from Horn USA is a user-friendly quick-change system that can be combined with W&F Micro quick-change holders and existing standard holders. In addition, toolholders without through-coolant ports can be used. Mechanical stops and coolant tubes allow the machine operator quickly and precisely to set up or exchange tools with ease, the company says.
The machine-specific units accept high-pressure coolant without external high-pressure coolant lines for individual tooling positions that handle more than 1,000 psi. The use of high-pressure coolant helps prevent problems associated with stringy chips, improving chip management.
Mechanical stops on the linear unit help to reduce operator error when exchanging tools. Each stop can be adjusted individually and locks into place to meet the requirements of machining applications. These stops establish accurate, repeatable points to work with.
With the addition of W&F Micro quick-change tooling, the operator can assemble the removable head and insert outside the machine, in preparation of the next tool change, during productive machining time. The connection is extremely stable, precise, and repeats within 3 microns when exchanging worn tooling.
Hummingbird takes on machining work that is too small for most shops to handle. In fact, Hummingbird tries not to handle it either. To accurately machine the tiniest parts, this shop relies on processes that are as hands-off as possible.
Horn USA has developed quick-change tooling systems to drastically reduce set-up and toolchange times for Swiss-type lathes, including those with through coolant.
A seemingly small amount of runout can still be too large for the tool. Reduce this runout, and tool life or productivity may dramatically increase.
