Swiss-Type Lathe Enables Work with Larger Parts
Hanwha Machinery’s XD42 is a larger-capacity Swiss-type machine designed to enable operators to produce larger-diameter Swiss parts.
Hanwha Machinery’s XD42 is a larger-capacity Swiss-type machine designed to enable operators to produce larger-diameter Swiss parts. The 42-mm (1.653") machine with guide bushing offers an alternative for producing some parts that are too large for a standard Swiss-type lathe, especially in the automotive industry, according to the company. According to the company, the XD42 is an efficient model for setting tools a short distance from the center of the headstock.
The bearings and toggles on the main and subspindles contribute to a stable machine structure along with strong chucking force via a large hydraulic cylinder as well as the machine bed’s highly rigid single-piece casting.
The machine is said to provide cost-effective parts production for heavy milling and cutting. The horizontal gang-type design offers a stable base and easy chip removal. Cross and back tools are available with ER20M as an option and a powerful motor (cross drill: 2.2 kW, 8 Nm; back drill: 1 kW, 3 Nm). The off-center drill next to the subspindle is powered by gears rather than belts.
The machine provides the option of a bar lifting unit for the automatic loading and replenishing of heavy barstock. Two anti-vibration units that are designed for the V block (hybrid static block) to guide the barstock efficiently. Other options include specialized tools, a chip conveyor and a larger coolant tank.
Turning hardened materials to grinding-like accuracies takes the right combination of part, machine and process parameters.
UNCC researchers introduce modulation into the tool path. Chip breaking was the goal, but higher metal removal rate is an intriguing secondary effect.
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.
