Features
FORTUNE PACIFIC UVM50 UVM50A Single-column Universal Combo Horizontal & Vertical Knee type swivel cutter head Elevator Ram-Type Milling Machine has reasonable construction and superior machining functions such as drilling, boring, milling of plane, inclined plane and slot, and such functions available by use of the corresponding attachments.
Classification & Definition of the Milling Machine tool, what is milling?
FORTUNE PACIFIC Vertical Milling Machine
The milling machine in which the spindle axis is perpendicular to the table is called vertical milling machine.
Knee-Type Milling Machine
The milling machine which has a knee like projection at the middle is called knee-type milling machine. It is characterised by a vertical adjustable work table resting on a saddle supported by a knee.
Ram-Type Milling Machine
A milling machine which has a ram on the top of the column is called ram type milling machine. Generally ram is used in vertical milling machine. It can be moved on the column in transverse direction (i.e. in and out when operated from the knee side).
Horizontal and Vertical Mills
FORTUNE PACIFIC Combo Horizontal and Vertical Mills offer both the capabilities of a Vertical Mill and a Horizontal Mill in one design. Changing the setup from one operation to the other is quick and simple. These mills are equipped with hard-chromed dovetail ways or hardened and ground box ways for superior wear resistance and separate motors drive the vertical spindle and horizontal spindle.
Elevator milling machine
There are universal, horizontal and vertical, etc., mainly used for processing small and medium-sized parts, the most widely used.
Single-column milling machine and single-arm milling machine
The former horizontal milling head can be moved along the column guide rail, and the table can be fed longitudinally; the latter vertical milling head can be moved horizontally along the cantilever rail, and the cantilever can also be adjusted along the column rail. Both are used to machine large parts.
Swivel cutter head ram-type milling machine
The cutter head containing the milling machine spindle is attached to the ram. The cutter head can be swiveled from a vertical spindle position to a horizontal spindle position or can be fixed at any desired angular position between vertical and horizontal. The saddle and knee are hand driven for vertical and cross feed adjustment while the worktable can be either hand or power driven at the operator's choice.

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.
