Knee Type Milling Machine: Precision Versatility for Industrial Manufacturing

What is a Knee Type Milling Machine?

A knee type milling machine is a fundamental machine tool distinguished by its vertically adjustable worktable mounted on a "knee" casting. This knee moves precisely up and down a fixed column via a screw mechanism, enabling accurate Z-axis positioning crucial for diverse milling operations.

Working Principle

The core principle involves a rotating milling cutter removing material from a workpiece secured to the table. The adjustable knee mechanism allows controlled vertical movement (Z-axis), while the table provides longitudinal (X-axis) and transverse (Y-axis) travel. This 3-axis control facilitates complex machining of flat, angular, and contoured surfaces.

Key Applications

  • Tool & Die Making: Precision molds, jigs, fixtures
  • Prototyping: Rapid part development
  • Maintenance Shops: Equipment repair & part fabrication
  • General Machining: Slotting, drilling, facing, keyway cutting
  • Aerospace & Automotive: Component manufacturing

Distinctive Features & Advantages

  • Vertical Adjustability: Knee movement enables quick workpiece height changes
  • Rigid Construction: Robust cast iron frame ensures stability
  • Manual & CNC Options: Traditional control or computer numerical precision
  • Turret Design (Common): Swiveling milling head for multi-angle machining
  • Wide Workpiece Compatibility: Handles various sizes and shapes

Primary Classifications

  • Vertical Knee Mill: Spindle axis perpendicular to table (most common)
  • Horizontal Knee Mill: Spindle axis parallel to table (for heavy stock removal)
  • Universal Knee Mill: Table swivels for complex angular cuts
  • Turret Mill: Head rotates on turret for flexible positioning

Main Components

  • Base & Column: Primary support structure
  • Knee: Vertically moving saddle supporting the table
  • Saddle & Table: Hold and position the workpiece (X/Y axes)
  • Milling Head: Houses spindle, motor, and quill (Z-axis)
  • Arbor/Spindle: Rotating shaft holding cutting tools
  • Controls: Manual handwheels or CNC interface

Evolution & Industry Significance

Since their development in the late 19th century, knee-and-column mills revolutionized machining. The iconic Bridgeport design (1938) popularized the turret style. While CNC machining centers dominate high-volume production, knee mills remain indispensable for flexibility, ease of use, and cost-effectiveness in job shops, schools, and repair facilities worldwide.
