CCLC-T1512 Fully servo-driven pull-up internal broaching machine

The fully servo pull-up internal broaching machine CCLC-T1512 is specially designed for automobile manufacturing, parts processing, and mechanical transmission system enterprises. It accurately addresses three core pain points: slow mold change in processing multiple types of parts, the need for automation upgrades with limited budgets, and difficulty in meeting high-precision requirements. Whether you are engaged in “small-batch and multi-variety production”, “automation transformation of old production lines” or “high-precision batch delivery”, you can find a matching solution.

Workpiece Literacy

• Application: Wheel hubs (load-bearing for automobile chassis) and flanges (connections in transmission systems) are core auto parts. The precision of their inner holes directly affects vehicle stability and service life.

• Key difficulties: Frequent mold changes are required for switching between multiple varieties (traditional equipment requires ≥20 minutes for mold change), the surface roughness of inner holes must be ≤1.6μm, the tolerance is ±0.005mm, and manual processing has low efficiency and a high rejection rate (≥10%).

Pain Points: Need to process 4 different specifications of wheel hubs/flanges, slow manual mold change, labor cost accounting for 35%, and limited budget preventing the purchase of multiple equipment.
Process Package:

• Equipment: CCLC-T1512 full servo pull-up internal broaching machine
• Procedures: Automatic loading and unloading → rapid mold change (≤5 minutes) → servo broaching → online dimension inspection → finished product output
• Parameter Range: Broaching speed 5-20m/min, repeat positioning accuracy ±0.005mm, mold change time <5 minutes
• Quality Control: Built-in online laser detection system to real-time monitor inner hole size/surface roughness; servo drive precisely controls broaching force to avoid part deformation.
• Expected Results: 80% improvement in mold change efficiency, 30% reduction in labor costs, scrap rate reduced to 2%, single equipment replacing 3 traditional semi-automatic broaching machines

Scene 2: Automation Upgrade of Old Production Lines

Pain Points: Traditional broaching machines rely on manual operation, with low efficiency (daily output ≤50 pieces), large precision fluctuations, and high labor intensity for workers.

Process Package:

• Equipment Adaptation: Directly replace semi-automatic broaching machines in old production lines without re-layout of the workshop.
• Core Upgrades: Added automatic loading and unloading unit + rapid mold change mechanism + digital twin monitoring system.
• Results: Daily output increased to 150 pieces (+200%), precision stability improved by 90%, number of workers reduced by 2/3

Scene 3: High-Precision Batch Delivery

Process Package:

• Key Technologies: Five-axis linkage servo control + cemented carbide broach (coated) + online residual stress detection.
• Parameters: Broaching force stably controlled at 120-150kN, surface roughness Ra≤0.8μm, tolerance ±0.003mm.
• Results: Scrap rate reduced to 1%, customer return rate 0, batch delivery cycle shortened by 25%

Cost/Efficiency Comparison Table

Case

A domestic automobile parts factory (with an annual output of 100,000 sets of wheel hubs) used this equipment, reducing the mold change time from 25 minutes to 4 minutes, saving 120,000 yuan in labor costs per month, lowering the scrap rate from 12% to 1.8%, and recovering the equipment investment within 3 months.
