Turnkey Continuous CNC Polishing Machine for Aluminum Die Castings

A rotary four-station cell built for aluminum alloy die castings — gates, flash and mold lines removed, surfaces ground and mirror-finished, all in one continuous cycle. Load the part, press start, take out the finished piece.

• 4 stations, 1 cycle — deburring → grinding → polishing → finish, no re-fixturing
• Ra 0.1 µm repeatable finish on die-cast aluminum (AN-oxide ready)
• 15-45 s cycle per part, continuous indexing, no idle time
• 1 operator, up to 3 machines — labor cost cut by 60-70%

A four-station CNC cell compresses the whole multi-process chain into one machine — with force control that protects soft aluminum from over-polishing.

Four processes completed in a single setup: The rotary table indexes in 90° increments, eliminating the need to unload or re-clamp the workpiece — delivering both superior precision and faster cycle times.

Continuous processing: Operations occur simultaneously across stations; equipment utilization approaches 100%, eliminating idle time caused by sequential processing.

Quick-change fixtures & program library: Changeovers between different aluminum casting models take less than 15 minutes — ideal for high-mix, low-volume production in the automotive parts and hardware sectors.

Force control to prevent over-polishing: Real-time adjustment of contact pressure and spindle speed for soft aluminum prevents edge rounding, surface discoloration, and deformation of thin-walled sections.

One operator, multiple machines: Operators handle only loading and unloading; the output of a single rotary table machine matches that of an assembly line staffed by 3-4 manual polishers.
