The Hydromat Epic R/T HS 16 indexing chuck rotary transfer machine produces precision metalcutting for cast parts, near-net shapes, profiled stock and standard bars. Available in 16- and 12-station models, the unit is fully integrated into the Hydromat machine program.
Each cutting station has its own CNC control system integrated into the tool spindle unit for a plug-and-play control architecture. The unit employs a linear scale for position feedback creating a true closed-loop CNC system, and the fixture compensation feature adds an additional level of accuracy by applying individual offsets for each fixture, the company says. The system has a feedback resolution of 1 µm.
The machine is said to utilize hydraulically actuated, self-centering two- or three-jaw chucks, or custom clamp fixtures, to provide precise part positioning for complex multi-axis machining. The chucks are positioned on the indexing table in a satellite arrangement and are indexed hydraulically. Indexing is free-programmable and can be arranged so that no cycle time is lost. Variable clamping pressure can be provided to critical chucks at certain stations.
