开槽器
开槽器 (Kāicǎoqì), commonly translated as slotting cutter or slot drill, is a type of cutting tool used to create slots, grooves, and recesses in materials. It is a fundamental tool in machining, woodworking, and metalworking.
Material:
- High-Speed Steel (HSS): Commonly used for general-purpose slotting, offering a balance of cost and performance. Suitable for lower alloy steels, non-ferrous metals, and softer materials.
- Carbide: Provides higher hardness, wear resistance, and cutting speeds. Ideal for harder materials like stainless steel, cast iron, and abrasive alloys. Carbide cutters are more expensive but offer longer tool life and improved accuracy.
- Cobalt HSS: Offers improved heat resistance and wear resistance compared to standard HSS, making them suitable for machining tougher alloys and higher-temperature applications.
- Solid Carbide: Offers the highest performance and is often used for precision applications.
Purpose:
The primary purpose of a slotting cutter is to remove material to form a specific shape – typically a slot or groove – in a workpiece. This is crucial for creating keyways, mortises, t-slots, and other features required for assembly, functionality, or aesthetic purposes.
Function:
Slotting cutters function by rotating at high speed while being fed into the workpiece. The cutting edges remove material, creating the desired slot or groove. The geometry of the cutter – including the number of flutes, flute angle, and overall diameter – dictates the chip formation, cutting efficiency, and surface finish.
Usage Scenarios:
- Metalworking: Creating keyways for shafts and hubs, machining t-slots for fixtures, forming grooves for O-rings and seals, and creating recesses for bearings.
- Woodworking: Cutting mortises for joinery, creating dadoes for shelves, forming grooves for paneling, and creating t-slots for workholding.
- Plastic Machining: Cutting slots and grooves in plastic components for various applications.
- Milling: Often used in milling machines to create complex slot features.
Common Types:
- Side Milling Cutter: The cutting edges are located on the side of the cutter. Used for creating slots and grooves with a specific width.
- End Milling Cutter: Features cutting edges on both the side and end. Can be used for both slotting and profiling.
- Slitting Saw: A thin, disc-shaped cutter designed for creating narrow slots.
- Keyway Cutter: Specifically designed for cutting keyways in shafts and hubs. Often features a tapered shank for precise alignment.
- T-Slot Cutter: Features a specific geometry to create t-shaped slots for workholding.
- Form Cutter: Designed to create specific shapes, such as dovetails or other complex profiles.
- Single-End & Double-End Cutters: Refers to the number of cutting ends on the tool. Double-end cutters offer increased efficiency but require more careful setup.
Key Parameters:
- Diameter: The overall diameter of the cutter.
- Cutting Diameter: The diameter of the cutting edges.
- Flute Length: The length of the cutting flutes.
- Number of Flutes: Affects chip evacuation and cutting efficiency.
- Flute Angle: Influences chip formation and cutting force.
- Shank Type: Typically cylindrical, Morse taper, or straight shank.
- Helix Angle: Affects cutting force and chip evacuation.
- Material Grade: Determines the cutter’s suitability for different materials.
