Specialized machine for reaming/milling arcs

Hinge:

The term "hinge" in industrial processing has two main interpretations, referring to...Precision hole machining toolsas well asFurniture hardware accessories.

If you are looking for specific drilling machine functions, please confirm whether you mean "automated drilling equipment with reaming capabilities" or "specialized machine for machining curved parts".

Milling arc:

In machining, "arc milling" refers to...Milling circular or curved contoursThe process is different from drilling (single-point downward). Arc milling uses the side or end cutting edge of the milling cutter to cut precise arc or irregular shapes on the workpiece through the linkage displacement of the tool on the X, Y, and Z axes.

1. Machining tools: Reamer/Drill-Reamer

In precision machining, a "hinge" usually refers to a hinge that possesses...Dual function of drilling and reamingThe compound cutting tool is commonly known as a "drill reamer" or "flat-bottomed drill reamer". 

• Function integrationTraditional processes require drilling holes first, and then replacing them with a reamer for finishing; the "reamer" design allows drilling and high-precision hole wall finishing to be completed in one feed stroke.
• Rounded corner designSome high-end reamers (such as rounded corner reamers) have a special cutting tip curvature design that can reduce machining stress and improve the surface finish of the hole bottom or corner.

2. Furniture Hardware: Arc Hinge

In the fields of interior design and hardware, "hinge" often refers to...Hinges with an arc-shaped design. 

• Application scenariosIt is often used for glass doors, shower rooms, wine cabinets, or curved cabinet doors.
• FeaturesThe design incorporates curved glass or corner structures, and commonly features 90-degree or 180-degree opening specifications. Some models also have a clamp-type design that does not require drilling. 

Main methods of arc milling

• Circular interpolation:
  This is the core function of a CNC milling machine: by controlling system commands (such as G02 clockwise and G03 counterclockwise), the machine tool moves two coordinate axes synchronously to outline a perfect arc path on the plane.
• Circular Ramping:
  While the tool moves in an arc, it is also slowly fed axially (Z-axis). This method is commonly used in...Enlarged holeAlternatively, creating larger circular grooves in solid materials can effectively reduce cutting resistance and improve chip removal.
• Profile milling:
  Arc-shaped machining is used to process the outer edge or inner cavity of a workpiece, and is often used to produce surgical instruments, aerospace parts or molds with complex curves.
