Main Applications of RTM500 C3 Bevel Gear Rolling Test Machine
RTM500 C3 CNC Bevel Gear Rolling Test Machine is designed to test gear pairs of right-angle straight bevel gears, spiral bevel gears and hypoid gears of work diameters up to 500mm in terms of tooth contact pattern, running noise and engaging backlash and also important basis for readjusting the parameters for the gear generating machines.
Features of RTM500 C3 Bevel Gear Rolling Test Machine
1. The driving headstock is driven by a servo motor and a high precision ball lead screw. Automatic feeding can be realized, the pre-set backlash can be kept repeatedly and the tooth can be set automatically.
2. The driving spindle adopts frequency variable speed regulation, ranging from 700~2000rpm, and the rotation direction of the spindle can be changed automatically.
3. The driven headstock adopts a suspended frame structure, increasing the structural rigidity and ensuring the stability of the engaging position of the gears to be checked.
4. The driven spindle adopts the loading made of electro-hydraulic proportion control. Automatic pre-set loading with a display function can be realized.
5. The machine is equipped with SIEMENS 828D CNC control system.
6. The machine is equipped with a sealed electrical cabinet, in which a thermo exchanger or an air conditioner may be adopted (optional).
7．The hydraulic pump station is located at the side of machine.

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.
