Technical parameters of RTM800 C2 Bevel Gear Rolling Test Machine
Main Applications of RTM800 C2 Bevel Gear Rolling Test Machine
RTM800 C2 CNC Bevel Gear Rolling Test Machine is a precise machine for testing quality of bevel and hypoid gears with the capacity of testing gear pairs up to 800mm in diameter. The runout, operating stability, mounting distance and tooth bearing of gear pairs can be accomplished as well as the testing results will be used as the coordinate setting data for gear cutting machines.
Features of RTM800 C2 Bevel Gear Rolling Test Machine
1. The machine is a longitudinal layout which facilitates the needs of testing big gears and easy operation. The machine base is composed of a low bed and a middle bed which are tightened together. The sliding base is mounted on the low bed while the driven headstock and swivel are on the sliding base; the column and driving headstock are mounted on the middle bed. When swiveling the swivel together with the driven headstock on sliding base, the shaft angle between two spindles can be adjusted from 45 to 180 degrees.
2. The sliding base (Z axis) and the column (X axis) are controlled by CNC control system to ensure the machine accuracy. The other operations are manually adjusted.
3. Both pinion and gear are automatically clamped on the spindle with hydraulic cylinders.
4. The loads on driving spindle are applied through electrical-hydraulic system and a mechanical lever to control the back pressure of hydraulic motor, so as to get the required brake load.
5. The sliding base and column are moving on the guide way of “V” type and being clamped through hydraulic system to ensure the structural rigidity of machine.
6. The machine is equipped with a SIEMENS 828D CNC Control System and AC digital servo system to accomplish the automatic or manual control and fault detect, as well as the tooth auto mesh function.
7. The spindle of driving headstock is driven by a dual-speed motor, rotating at 1150 or 555 rpm.

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.
