Video: “Three-Stack” Turret Lathe with ATC
This turret lathe features an automatic toolchanger to increase flexibility for job shops that encounter a variety of different part types.
There are various B-axis turn-mill machines that have automatic toolchangers (ATCs) to tend their milling heads. Hwacheon now offers its C1 series CNC lathes with Y-axis motion and an ATC that tends its “three-stack” turret. In addition to tool stations that can be used to perform operations on either the main or subspindle, the turret has six stations with Capto toolholder interfaces to accommodate automatic tool change-out, like on a B-axis turn-mill, VMC or HMC (see video above). This offers increased flexibility to job shops that encounter a diverse array of workpieces and small batch sizes.
As demonstrated at this Cincinnati-area shop, machines that both mill and turn shine brightest when workpieces are massive.
While aluminum molds are commonly used to create prototypes or to serve as stopgap bridge tooling, they are starting to receive greater attention for production work. This shop’s approach to creating aluminum molds in one day to three weeks is the same for each of these situations.
The additional rotary milling axis on these machines allows them to complete many types of complex parts in a single setup, but these machines have gained a reputation for being difficult to program. Today’s CAM software, however, eases the programming challenge significantly.
