Horizontal Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Horizontal machining occurs on a horizontal machining center (HMC), which employs a spindle that is parallel to the ground floor. With a horizontally oriented spindle, tools stick out of the side of the tool holder and cut across the side of a workpiece, encouraging chips to fall away from the table. Horizontal machining centers also allow for two-pallet changer integration to facilitate unattended operation and reduce part cycle times.
While FORTUNE PACIFIC horizontal machining centers range in size and capacity, we design each one with quality, reliability, ease of operation and safety in mind. Furthermore, thanks to our Production-On-Demand manufacturing philosophy, all of FORTUNE PACIFIC horizontal machining centers incorporate the latest, most advanced milling technology for boosting productivity and growing your business.
Whether your application calls for heavy-duty or high-speed machining of big or small parts in a high- or low-production environment, FORTUNE PACIFIC offer the widest range of horizontal machining centers in the industry to ensure you have the best solution for your needs with the lowest cost of ownership.
The Twin Pallet Horizontal Machining Center is said to be designed to help job shops step into higher levels of production, such as a 24/7 duty cycle to maximize productivity. FORTUNE PACIFIC says the machining center offers a rigid boxway construction, accuracy, consistent repeatability, standard simultaneous fourth-axis machining and a range of cutting power.
Using a digital control for faster program execution speeds, Twin Pallet Horizontal Machining Center produces a smoother surface finish when contouring at high spindle speeds.
Twin Pallet Horizontal Machining Center with automatic pallet changer are designed for higher efficiency and reliability. With a horizontally oriented spindle, the tool cuts the workpiece on its side. This allows for the chips to fall away from the work table. HMC’s are also designed to be more rigid and with larger tool storage capacities. This design allows for increased repeatability and overall versatility. Horizontal Machining Centers without pallet changers are also available if you are just looking for a more rigid solution over a vertical machining center.
Twin Pallet Horizontal Machining Center Series with automatic pallet changer combine proven machine design with advance technology in control and manufacturing. Reliability and performance make this series a favorite among demanding job shops and in-house productions alike. The heavy cutting spindle and rigid machine structure enable higher machining efficiency with better finish and longer tool life – resulting in greater productivity and profitability all around.

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.
