Motor Shaft Straightening Machine

SKS20 Motor Shaft Automatic Straightening Machine

The SKS20 motor shaft straightening machine is an automated and precise straightening equipment specially designed for motor rotor shafts and output shafts. Its core advantages are as follows:
  1. Automated operation: Equipped with optional automatic loading and unloading + NG sorting mechanism to realize unmanned continuous production;
  2. Precise control: Servo motor loading + 3 straightening points + 5 measuring points, with a straightness error of ≤±0.01mm;
  3. Material adaptation: Arc indenter avoids surface crushing, and the 100-160℃ heat-resistant design supports high-temperature alloy shafts;
  4. Intelligent integration: Reserved MES interface, which can be connected to the smart factory system to realize data traceability and production capacity monitoring;
  5. Safety compliance: CE certification + safety light curtain + emergency button + safety relay to ensure operational safety;
  6. High efficiency and cost reduction: Replaces manual straightening, improves efficiency by more than 300%, and saves 50% of labor costs.

The SKS20 motor shaft straightening machine is specially designed for the production scenarios of automotive motors, industrial motors, new energy electric vehicle motors, and household appliance motors. It accurately addresses the pain points of “low efficiency in manual straightening, large fluctuations in precision, and high rejection rates”. Whether you need to upgrade an old production line to replace manual labor, reduce costs and increase efficiency in large batches, achieve rapid delivery in small batches, or perform precise straightening of high-temperature motor shafts, you can find a matching solution.

 

Workpiece Literacy: Applications, Key Difficulties, Common Materials

The motor shaft is a core component of the motor, responsible for transmitting torque and supporting the rotor. Its bending deformation will lead to large vibration of the rotor during operation, excessive noise, and abnormal wear of the bearing, directly affecting the performance and service life of the motor. Common materials include carbon steel (45#), alloy steel (40Cr), stainless steel (304), aluminum alloy (6061), etc. Bending deformation is prone to occur during processing/transportation/maintenance, and manual straightening is difficult to ensure consistency.

 

Scenario Grouping Solution

Scenario 1: Upgrading of old production lines / Localization replacement (manual to automatic)

Pain points: Manual straightening relies on experience, with an efficiency of only 500 pieces/day, a scrap rate of 15%, and labor costs accounting for 20%.
Solution: SKS20 + automatic loading and unloading + NG sorting mechanism. It adopts double-sided center clamping + servo motor loading, with 3 straightening points + 5 measuring points (including 2 benchmarks) to achieve full-dimensional detection; the arc indenter avoids surface crushing, and the 100-160℃ heat-resistant design supports hot straightening.
Benefits: Efficiency increased to 2000 pieces/day (3 times), scrap rate reduced to 3%, labor cost saved by more than 50%, and compliance with CE certification for safety.

Scenario 2: Cost reduction and efficiency improvement for mass-produced motor shafts

Pain points: In mass production, manual straightening is slow, unable to meet order delivery, and scrap losses are high.
Solution: SKS20 automated continuous operation system. Optional high-speed automatic loading and unloading mechanism, MES interface connected to the smart factory system to realize data traceability and production capacity monitoring; tool life extended by 30%, straightening cycle shortened to 15 seconds/piece.
Benefits: Unit cost reduced by 18%, delivery cycle shortened by 40%, production capacity increased to 3000 pieces/day (mass production scenario).

Scenario 3: Precise correction of high-temperature motor shafts

Pain points: The hot deformation of high-temperature alloy motor shafts (such as new energy motors) is difficult to control, and the accuracy of manual straightening is insufficient.
Solution: SKS20 heat-resistant components + servo precise loading. The equipment supports 100-160℃ hot straightening, measuring points feed back straightness data in real time, and the error is controlled within 0.01mm; the arc indenter is adapted to the characteristics of high-temperature materials to avoid secondary deformation.
Benefits: 100% straightness compliance rate, 40% reduction in motor operation vibration, and 25% extension of bearing life.
