FRONT FORK STEM CUTTING, CHAMFERING AND THREAING

• Completes cutting, inner/outer chamfering and external threading in one station
• Reduces the need for multiple machines and repeated handling
• Suitable for city bikes, MTBs and e-bikes with stable volume demand
• Helps maintain consistency across steerer tube processing
• Multi-functional high speed cutting machine setup improves overall production efficiency and cycle stability

One Machine for Cutting, Chamfering and Threading

1. High Speed Cutting and Consistent Tube Length

• Cuts full-length steerer tubes to required dimensions
• Keeps length variation under tighter control
• Reduces repeated clamping and unclamping
• Supports more stable upstream-to-downstream flow
• Multi-functional high speed cutting machine enables faster cycle time while maintaining dimensional accuracy

2. Inner and Outer Chamfering

• Prepares tube edges for threading and assembly
• Reduces burr formation on both inner and outer edges
• Lowers risk of stress concentration on tube ends
• Helps downstream threading and fitting run smoothly
• Integrated with multi-functionalhigh speed cutting machine to keep edge finishing consistent

3. External Threading in the Same Cycle

• Aligns thread position with cut length in one setup
• Reduces misalignment between length and thread location
• Lowers rework caused by damaged or uneven threads
• Simplifies process timing with fewer stations involved

FAQ – JD-05A Front Fork Steerer Machine

1. Difference Between JD-05A and Standard Threading Machines

• Standard machines only handle threading
• JD-05A combines cutting, chamfering and threading in one cycle
• Reduces number of machines and handling steps
• Helps maintain alignment between length and thread position
• Multi-functional high speed cutting machine improves process integration compared to single-function machines

2. Reduction of Manual Errors

• Processes all steps in a single clamping cycle
• Reduces need for manual repositioning
• Keeps length, chamfer and thread alignment consistent
• Lowers operator-dependent variation
• Multi-functional high speed cutting machine helps standardize production quality across shifts
