Applications of BGL600 A5 Spiral Bevel Gear Lapping Machine
BGL600 A5 Spiral Bevel Gear Lapping Machine is designed to lap at high speed and precisely the spiral bevel and hypoid gear pairs of diameters up to 600mm, and modify properly the distortions of the gears after the heat treatment. The surface texture after lapping is up to 0.8 and higher, and the positions and sizes of the tooth contact patterns are improved. The gear pairs drive smoothly with low noise, and their load capacity is increased. This machine is suitable for the modifications of gears used on the rear axles after heat treatment for the heavy-duty, medium-sized and light-duty trucks.
Main Characteristics of BGL600 A5 Spiral Bevel Gear Lapping Machine
The pinion spindle is the driving spindle, which makes the H (X) movements and the V (Y) movements along the column. The gear spindle is the driven spindle and makes the G (Z) movements. All the V, H and G movements are performed through the precision ball screws driven by servo motors along the linear guideways. Motor spindles are adopted for both the pinion and gear. The speed of such spindles is up to 3000rpm with smooth transmission, high precision and low noise level, thus prolonging the service life of the machine.
A SIEMENS 840D CNC control system is equipped on the machine to perform the simultaneous 3-axis movements, automatic adjustments of the mounting distance, automatic tooth setting and backlash compensation, and the recognitions of burs and collisions. 2～50Nm toque load can be applied through the high-speed and great torque spindle. Thanks to the direct-driving spindle design of the horizontal arrangement, the machine can sustain the dynamic stability at high speed. A high-pressure pneumatic membrane pump is used to spray the lapping compound of 5kg/cm2 pressure on the meshing point at a high speed. The machine is characterized by the shorter lapping time, increased productivity, ultra-high controllable speed at different points. The machine operation is more convenient because of swiveling control panel and more humane man-machine interface. The machine enclosure is nice and safe, and the automatic telescopic safeguard door facilitates the loading and unloading of the workpiece.

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.
