Considerations for Sewing Machine Assembly

Attention to detail during sewing machine assembly is crucial, as it significantly impacts the equipment's performance, whether it's the initial assembly or a major overhaul. Poorly assembled sewing machines exhibit lower accuracy, reduced performance, increased noise, heavier torque, and shorter lifespans. Conversely, with careful component selection, assembly, and precise adjustments, even certain low-precision parts can yield well-performing equipment.

During the assembly process, some aspects are often overlooked but can have a notable impact on assembly quality and need careful consideration.

◆Ensure Component Cleanliness:

Ensuring the cleanliness of sewing machine components through meticulous cleaning and washing is the foundation for achieving assembly quality and extending the machine's lifespan. This is particularly critical for parts such as bushings, bearings, oil pumps, and components with rotational and swinging fits.

Failing to clean components during the assembly of various shaft-related parts can lead to various issues. Mild consequences may include elevated bushing temperatures and excessive transmission torque, while severe cases may result in accelerated wear and serious malfunctions like "binding."

◆Follow Procedures:

For sewing machine components that undergo surface treatments such as painting or electroplating, there is often a residue layer on the assembly mating surfaces, including holes, slots, flat surfaces, and threaded holes. Therefore, before assembly, these parts must be precision-machined in accordance with technical specifications, as outlined in the manufacturing process.

Failure to adhere to the specified technical requirements during assembly can prevent the sewing machine from functioning correctly. Incorrect mutual positioning of components or mechanisms also affects the sewing machine's operational performance.
