What are the differences in working principles between servo tightening machines and ordinary tightening machines? In the field of industrial automation assembly, tightening machines are key equipment, and their technological evolution directly reflects the manufacturing industry’s pursuit of precision and efficiency. This article will deeply analyze the differences in working principles between servo tightening machines and ordinary tightening machines, compare their performance characteristics, and discuss their respective application scenarios.

1. Working Principle:
The servo tightening machine uses a servo motor as its core power unit, achieving precise control of angle and torque by receiving pulse signals. Its closed-loop control system consists of three parts:
2. Technological Advantages
1. Working Principle:
Ordinary tightening machines (such as pneumatic tightening machines) rely on cylinders or ordinary motors for drive, and limit the maximum torque through mechanical structures. Their control logic is an open-loop system, lacking a real-time feedback mechanism, and their accuracy is significantly affected by fluctuations in air pressure and voltage.
2. Performance Characteristics
| Comparison Dimensions | Servo tightening machine | Ordinary tightening machine |
|---|---|---|
| Control precision | ±2% | ±5% or more |
| Feedback mechanism | Closed-loop control (sensors + algorithm) | Open-loop control (no feedback) |
| Multi-axis collaboration | Supports 36-axis synchronization | Single-axis independent operation |
| Data Records | Full process traceability | No data logging function |
| Applicable Scenarios | Automotive engines, aerospace, and electronics assembly | Furniture manufacturing, general industrial assembly |
1. Servo tightening machine
2. Ordinary tightening machine

Servo tightening machines, through closed-loop control and multi-axis collaborative technology, have redefined the precision boundaries of tightening operations, becoming the preferred solution in high-end manufacturing fields such as automotive, electronics, and aerospace. Meanwhile, conventional tightening machines, with their cost advantage, still hold a place in budget-sensitive scenarios. With the advancement of industrial intelligence, technological iterations of servo tightening machines (such as AI predictive maintenance and digital twin integration) will further solidify their core position in the field of precision assembly.

As a well-known domestic supplier of industrial intelligent tightening equipment, SUDONG Intelligent has been invited to participate in the exhibition and will make a stunning appearance at booth 6355 in Hall S6, showcasing the company’s independently developed new technologies, products, and concepts in intelligentization, automation, and digitalization in recent years to industry professionals.

Founded in 2007, Sudo Intelligent Tightening Technology Co., Ltd. has always remained true to its original aspiration and forged ahead. It mainly engages in the production, manufacturing, and sales of brushless electric screwdrivers, torque testers, and related supporting products. It has always adhered to the combination of independent research and development and technological innovation, continuously breaking through the technical barriers in the industry. It broke the long-term monopoly of foreign fastening brands and created a Chinese brand of “fastening tools”. With digitalization, intelligence, and integration, it continues to lead the Chinese industry to the world.

High-quality development of the manufacturing industry is of paramount importance to high-quality economic development. Building a modern socialist country and strengthening the real economy are both inseparable from the manufacturing sector. This exhibition focuses on intelligent manufacturing equipment and technologies, showcasing the latest achievements in the equipment manufacturing industry in recent years. It covers advanced products and technologies in intelligent manufacturing, automation, and digital factories, as well as complete factory automation production solutions. Intelligent industrial upgrading has become an irreversible trend.
As a key component of electronics manufacturing enterprises, electric screwdrivers are undergoing a new round of intelligent upgrades, playing an increasingly important role in industrial manufacturing, especially in the automotive industry. Against this backdrop, SUDONG’s brushless servo intelligent torque sensor series and brushless clutch-type torque converter series, among other products, have gained widespread popularity among users in the automotive tightening shaft, new energy, and rail transportation sectors due to their superior performance.
Quick-acting brushless clutch with fixed torque series
The Quick-Motion Brushless Clutch Torque Series features a built-in contactless switch, eliminating the need to replace consumables and boasting an exceptionally long service life. It integrates a new intelligent counter to effectively manage yield rates. The brushless motor delivers stable torque output, is easy to operate, and provides extended screwdriver life. Infrared intelligent clamps and LED indicator lights allow users to visually assess screw tightening, making it an excellent industrial-grade tightening tool for electronics professionals.

Speed-Motion Brushless Servo Intelligent Torque Sensor Series
The brushless servo intelligent torque sensor series allows for free programming of the tightening and assembly process. Within its performance parameter range, torque, speed, waiting time, and rotation direction can be freely set and adjusted according to different tightening process requirements, achieving precise tightening.

Precise control is achieved throughout each tightening process via built-in torque and angle sensors, with all critical tightening parameters recorded in real time. Servo control technology ensures torque accuracy within ±3% of the standard deviation for millions of tightening assemblies. Built-in current and angle measurements enable precise control and monitoring of each tightening process, recording all critical parameters and ensuring maximum precision.
Under normal operating conditions, the brushless servo intelligent torque sensor achieves a Cmk ≥ 1.67 (torque setting tolerance ±10%), conforming to ISO 5393 and Six Sigma principles. A Cmk value of 1.67 means a failure rate of only 0.6 times per million screws, resulting in a pass rate of 99.99994%. Furthermore, the use of a brushless motor, coupled with the SD-PF5015 or SD-PF5030 controller, ensures flexibility and reliability in the tightening process, helping manufacturing enterprises achieve true precision and intelligent control.
Despite foreign technological blockades and a shortage of domestic talent, China’s path to industrial intelligence remains long and arduous. However, thanks to strong national support and the fervent anticipation of countless Chinese people, more patriotic enterprises are emerging, undeterred by difficulties and dedicated to the research and development of intelligent equipment, creating a bright and new future for China’s industrial intelligence. Sudo Intelligent hopes to contribute to the significant transformation from “Made in China” to “Intelligent Manufacturing in China” with its small intelligent electric screwdriver.
