Swiss-Type Tool System Requires 30 Seconds for Changeover
Arno Werkzeuge USA’s Auto Fast Change (AFC) tool system is designed to provide faster setups and to reduce the downtime with in-process tool changes in Swiss-type machining operations. The AFC system is a two-piece, universal toolholder mounted inside the machine. A separate quick-change toolholder slides into the end of the stationary block and is locked into place by two screws. The AFC is said to take 30 sec. to change.
The tool system also eliminates the need for external plumbing to facilitate cooling. The issues created by excess chips and debris mixed in with coolant inside the machine are minimized as well, according to the company. The AFC is designed with built-in through-coolant capabilities. In total, there are five inlets for porting the coolant on the AFC toolholder block that operators can use to direct coolant flow.
Companies concerned about strict quality requirements regularly check toolholder tapers for wear or inaccuracy because these conditions can jeopardize the results of a critical operation. However, a shop can check tapers quickly and reliably with air gages. These devices can be used effectively without special operator training. For measuring taper in a production environment, few other methods can match the speed and performance of air, as multiple-circuit air jets can be placed in very small taper gages.
Angle heads can enable a three-axis machine tool to be more versatile. That said, this shop explains that there’s more to getting started using them than simply loading them into a machine’s spindle.
The book on hydraulic toolholders is that they are fussy to set, fragile to operate and expensive to buy. So why do many shops choose them over other holders that seem less demanding? This Chicago mold builder has good reasons for its choice.
