Subheadings
Products classified under HTS 8466.93.60
Cast Iron Machine Base for CNC Lathe
A cast iron base component for CNC lathes under heading 8458, cleaned and machined solely to remove casting fins, gates, sprues, and risers for precise location in finishing machinery. It serves as the foundational support structure ensuring stability during metal turning operations. This part is not advanced beyond basic preparation and falls under HTS 8466.93.60 due to its specific processing limitations.
Cast Iron Bed Frame for Horizontal Boring Machine
Rough cast iron bed frame for horizontal boring machines (heading 8459), processed only by cleaning and minimal machining to eliminate sprues and enable fixture placement. Provides rigid support for the worktable and spindle during large hole boring operations. Limited processing keeps it under HTS 8466.93.60 for cast-iron parts.
Cast Iron Column Support for Vertical Machining Center
Cast iron column for vertical machining centers (heading 8460), featuring only cleaning and machining to remove risers and fins for subsequent finishing operations. Supports vertical spindle movement with required rigidity for precision milling. Meets HTS 8466.93.60 criteria as unprepared cast-iron machine part.
Cast Iron Spindle Housing for Drilling Machine
Rough cast iron housing for drilling machine spindles (heading 8456), cleaned with minimal machining only at casting defects and location points. Encases precision spindle components during radial drilling operations on large workpieces. Classifies under HTS 8466.93.60 due to limited preparation stage.
Cast Iron Worktable Mounting Base for Milling Machine
Cast iron base for securing worktables on milling machines (heading 8460), featuring cleaning and machining limited to sprue removal and fixture locators. Provides stable mounting platform for workpiece manipulation during multi-axis milling. HTS 8466.93.60 applies to this semi-finished casting.
Cast Iron Gearbox Mounting Bracket for Lathe
Rough cast iron bracket for mounting gearboxes on engine lathes (heading 8458), cleaned and machined only to remove gates and provide basic location holes. Ensures alignment of speed change mechanisms during turning operations. Limited processing qualifies for HTS 8466.93.60.
Cast Iron Headstock Casting for Boring Mill
Semi-finished cast iron headstock for boring mills (heading 8459), with cleaning and minimal machining restricted to riser removal and positioning features. Houses spindle and feed mechanisms for deep hole boring in large castings. Classifies as HTS 8466.93.60 rough part.
