△ Small-Vibration Test of the Template Machine (using Zhongweixing Template Machine Control System)
Today, let’s talk about the issue of mechanical vibration in template machines.
To meet the ever-increasing demands for process precision, garment template machines currently on the market tend to replace stepper motors with servo motors. In terms of the transmission system, the materials used for the feed belts or lead screws vary, leading to differences in actual machining performance. Moreover, excessive vibration during operation can result in:
01. Uneven stitch lines affect processing quality.
02. Prone to wire breakage, thereby reducing processing efficiency.
03. Generates significant noise
04. Affects the accuracy of needle insertion.
05. Affecting the machine's service life
To reduce mechanical vibrations, our first thought was to lower the operating speed of the equipment and employ reasonable acceleration and deceleration control for each needle’s start and stop. During the machining process—and especially at the corners at the beginning and end—by using smooth acceleration and deceleration and coordinating with the spindle rotation, we can effectively minimize vibrations while ensuring excellent performance in the resulting pinhole patterns.
In addition, the control system employs an S-shaped acceleration and deceleration profile to minimize vibrations caused by inertia.
Through years of in-depth research into template sewing technology, Shenzhen Zhongweixing has developed a garment template machine control system that is renowned for its stability and efficiency. Its S-curve acceleration and deceleration function ensures smooth changes in operating speed, thereby optimizing motor performance, reducing impact, and significantly enhancing both the quality and efficiency of template machine sewing.

Mechanical conditions
Brand: Zhong Weixing
X-axis: Servo, 400W, ball screw
Y-axis: Servo, 750W, ball screw
Due to limitations in experimental conditions, the X-axis—whose impact on the experimental results was relatively minor—was changed to be driven by a belt. During the experiment, data were collected from the middle section of the machine. Data collection began when the machine started processing the graphic pattern, and the peak values recorded during the processing time were used as the standard. The specific data are as follows.
| Spindle speed Revolutions per minute |
Empty travel speed mm/minute |
X-axis movement Distance mm |
Y-axis travel distance mm |
Stitch length mm |
decibel Maximum value |
| 1000 | 40000 | 538.6 | 608.9 | 2.5mm | 65.5 |
| 2000 | 40000 | 538.6 | 608.9 | 2.5mm | 65.2 |
| 2600 | 40000 | 538.6 | 608.9 | 2.5mm | 65.8 |
Summary
By analyzing the measured noise decibels, we found that the vibration level of Zhongweixing Electric Control is less affected by speed. When the machine operates at medium to high speeds, Zhongweixing Electric Control exhibits a significant advantage in terms of vibration.
Based on the measured data above, do you now have a new understanding of the Zhongweixing template machine system?
