Technical parameters of WGM200 CNC Worm Wheel Gear Grinding Machine
Applications of WGM200 CNC Worm Wheel Gear Grinding Machine
WGM200 CNC Worm Wheel Gear Grinding Machine is a high efficiency and precision machine with good universality, which is used to grind standard or modified involute gears. WGM200 is suitable for grinding of precision, small and medium module (0.5-2mm) and size (tip diameter ≤200mm) spur and helical gears in batch production in industries of aircraft, automobile, machine tool, motor bicycle, electric tool and transmissions devices.
Features of WGM200 CNC Worm Wheel Gear Grinding Machine
1. WGM200 employs CNC synchronous drive. A worm grinding wheel meshes with gear teeth (workpiece) to achieve continuous generating grinding, which gains the machine high precision and efficiency.
2. High precision CNC synchronous drive makes grinding wheel rotary axis, workpiece rotary axis, workpiece radial feed axis, workpiece tangential feed axis and workpiece axial movement axis can simultaneously grind, which can accomplish the action of indexing drive, axial differential, tangential differential and longitudinal modification.
3. Continuous shift grinding: when workpiece tangential feed axis and workpiece rotary axis are simultaneously moving, they keep continuous shift state. Since contact between grinding wheel and workpiece always keeps new dressed surface during grinding, deep cutting grinding is guaranteed, which improves grinding efficiency.
4. Profile and longitudinal modification: profile modification is finished with special diamond rollers; longitudinal modification is realized by CNC controlled simultaneous workpiece radial feed axis and workpiece axial feed axis moving, thereby, all kinds of longitudinal profile may be obtained.
5. High speed synchronous drive: the speed of grinding wheel is 2400 rpm (common grinding wheel) being 2.6 times as that of the similar machine, and the speed of workpiece spindle reaches 120 rpm, which increases continuous generating speed to further improve grinding efficiency.
6. Direct generating gear by grinding: high rigidity structure and suitable grinding wheel for small module (m≤0.8) gear, gear blank can directly be ground into gear, which simplifies process and saves production cost.
7. High quality accessories: CNC system employs French NUM1060; servo system employs German SIEMENS. Grating measuring system, roller bearing, ballscrew, linear guideway and hydraulic elements are all from famous manufacturers, thus ensuring high precision and reliability.
8. WGM200 also adopts large flow cooling device, electrostatic fog collector and oil temperature controller.

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.
