CCLC Full Servo Screw Broaching Machine

Are you troubled by the low precision, slow efficiency, and high maintenance costs of hydraulic spiral broaching machines? The CCLC-0508-LXSF/2 full-servo spiral broaching machine is tailor-made for the processing of one-way clutch spiral internal splines, bringing 5 core values: ① Servo drive precisely controls the spiral angle/broaching speed, improving the tooth profile accuracy to ±0.01mm; ② Dual-station parallel processing directly increases productivity by 30%; ③ Automated processes (automatic tool lifting/feeding/chip cleaning) reduce manual intervention and lower labor costs by 50%; ④ Imported components such as German INA guide rails and Japanese Yaskawa servos double the service life of the equipment; ⑤ Fully sealed sheet metal design prevents cutting fluid leakage, complying with EU environmental standards. Whether you are an auto parts manufacturer or an agricultural machinery equipment supplier, this broaching machine can help you solve production bottlenecks and achieve cost reduction and profit increase.

Workpiece Literacy: Key Information on One-Way Clutch Spiral Components

The one-way clutch (overrunning clutch) is a core component of automotive starters and agricultural machinery engines. Its spiral internal spline is responsible for transmitting torque and preventing reverse rotation, directly affecting the reliability of the entire machine. Common processing materials include 45 steel, 20CrMnTi alloy steel, and high-temperature alloys (for extreme working conditions). The geometric characteristics are: complex tooth profile (helix angle adjustable from 0-30°), high matching accuracy requirements (tooth side clearance ≤ 0.02mm), and surface roughness Ra ≤ 1.6μm. Common risks in processing include: tooth profile deviation leading to jamming, thermal deformation affecting dimensional stability, residual iron filings damaging the workpiece surface, and poor consistency in mass production.

Overview of the Process Flow: Closed-Loop Control from Blank to Finished Product

The CCLC servo broaching machine adopts a full-process closed-loop design of “blank preprocessing → double-station rough broaching → finish broaching forming → automatic surface cleaning → online inspection → finished product output”, with precise control integrated into each link:

1. Blank preprocessing: Remove the oxide scale from forgings/castings to ensure the contact surface of the broach is flat;
2. Double-station rough broaching: Custom broaches are matched with a servo rotation system to quickly remove the allowance (broaching speed 8-12m/min);
3. Finish broaching forming: High-precision broaches + real-time online measurement, adjust the helix angle (0-30°) and broaching pressure to ensure tooth profile accuracy;
4. Automatic surface cleaning: Built-in high-pressure air guns automatically clean iron chips to avoid residual damage to workpieces;
5. Online inspection: Keyence sensors collect dimensional data in real-time, and automatically alarm when out of tolerance;
6. Finished product output: The door opens automatically, and the workpiece falls into the material box, waiting for the next cycle.
