STEM AUTO CUTTING AND CHAMFERING

JD-03C Auto Chamfering Machine for Bicycle Front Fork Steerer Tubes

• Combines tube cutting and chamfering in one setup
• Reduces processing time and part handling steps
• Improves consistency of tube length, chamfer angle, and surface appearance
• Helps reduce human error in manual or semi-manual operations
• Supports stable front fork steerer tube preparation process

Processing Advantages

1. Single-Cycle Cutting and Chamfering

• Performs cutting and chamfering in one clamping cycle
• Reduces workstation transitions
• Improves overall production efficiency

2. Improved Dimensional Stability

• Keeps steerer tube length and chamfer consistent
• Improves visual quality of tube ends
• Reduces variation between operators

3. Better Line Efficiency

• Optimizes operator utilization
• Increases production line capacity
• Reduces idle handling time

4. Reduced Damage Risk

• Minimizes tube deformation from repeated handling
• Reduces surface scratches during transfer
• Improves overall part protection

5. Easier Process Integration

• Fits into upstream and downstream production steps
• Supports forming, threading, and welding preparation
• Creates smoother production flow

Applications and Scope of Use

1. Bicycle Front Fork Steerer Tube Processing

• City and urban bike forks
• MTB and off-road bike forks
• E-bike and pedal-assist bike forks
• Supports common steel and alloy tube sizes

2. Multi-Diameter Tube Compatibility

• Supports common bicycle production tube sizes
