HGN(K) Series Hydraulic Guillotine Shears Introduction
HGN (K) series power squaring shear machine adopts an optimized frame designed by UG-software. The wholly welded structure shows good strength and rigidity. Stable integrated hydraulic system contributes to safe and reliable operation. This type of shearing machines allows for blades gap and shearing angle adjustment, which is a key point to get desired products.
Characteristics
1. HGN(K) series hydraulic guillotine features in a unique turret structure of three idler rollers guiding the rail. The former pre-pressing lead rail makes the turret be tightly between the upper rail and the lower rail and continually repeat reciprocating action.
2. These power squaring shear machines have the merits of integrated hydraulic system, with high quality hydraulic components and seals made by world-famous companies, so as to minimize hydraulic tubing to the least degree and ensure safe and reliable operation.
3. Hydraulic components and seals are all in the sizes conforming to ISO and DIN standards.
4. When cutting plates of different kinds and thicknesses, blades clearance can be easily adjusted through a blades gap quick adjustment device. In addition, blades gap value is shown on a dial plate.
5. Shear angle adjustment is available so that material distortions could be minimized.
6. Our hydraulic guillotines are equipped with a centralized button station, contributing to easy operation.
7. This series power squaring shear machine is also characterized with brief appearance and great shape.

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.
