The inspection results are displayed directly on the screen, while OK/NG products can be automatically classified according to the production requirements. As a result, the machine helps shorten inspection time, reduce manual operations, and improve the stability of quality control in mass production. In the following article, let's explore in detail the structure and operating principle of the Shaft Diameter and Thickness Measuring Machine with CNC VINA.

What is a shaft diameter and thickness measuring machine?

The shaft diameter and thickness measuring machine is an automatic measuring and inspection system used to inspect the dimensional parameters of shaft-, tube-, and similarly shaped components. The machine can measure the outer diameter, wall thickness, and other related dimensions according to the technical requirements of each product. It is commonly used in production lines that require fast and continuous dimensional inspection while minimizing dependence on manual measurement operations.

Instead of using manual measuring methods such as calipers, micrometers, or other mechanical measuring instruments, the automatic measuring machine uses sensors and dedicated measuring units to determine product dimensions. Products are conveyed to the inspection position by a conveyor or workpiece feeding mechanism and are then accurately positioned before measurement. This process ensures that products are inspected under the same sequence and measurement conditions, making the system suitable for quality control requirements in mass production.

• Laser marking unit (Optional): Marks required information on the product.
• Diameter measuring unit: Uses a non-contact Keyence laser measuring device to provide accurate measurements according to the product requirements.
• Thickness measuring unit: Uses a Mitutoyo measuring device, with measurement data digitally stored on the computer.
• Control and display unit: Includes a PC, keyboard, touchscreen HMI, LCD display, and other related components.

The shaft diameter and thickness measuring machine is operated and performs measurements fully automatically. The movements of the workpiece are recorded by a high-precision AI-based control system. The system automatically operates, rotates, and measures the workpiece, calculates the measurement results, and displays them to the operator.

Instructions for operating and using the shaft diameter and thickness measuring machine

The shaft diameter and thickness measuring machine is designed to automate the dimensional inspection and quality control process. To ensure stable operation, high measurement accuracy, and a long service life of the equipment, operators need to understand the operating procedure as well as the important precautions during use.

Operating instructions for the shaft diameter and thickness measuring machine

The shaft diameter and thickness measuring machine operates through an automatic process that combines a conveyor, sensors, transfer mechanisms, and measuring units to inspect product dimensions while classifying products as acceptable (OK) or unacceptable (NG). The following procedure describes the machine's operating sequence, from placing the product on the conveyor to completing the inspection and removing the product.

• Step 1: The operator places the product at the beginning of the conveyor.
• Step 2: The sensor detects and checks the incoming product.
• Step 3: The sensor detects the presence of the product at the laser marking position. The laser marking machine then starts marking the product.
• Step 4: After marking is completed, the conveyor moves the product to the diameter measurement position, where the sensor checks the product.
• Step 5: The transfer mechanism moves the product into the diameter measuring unit for measurement. Products that meet the requirements are returned to the conveyor, while NG products are placed into the NG product box.
• Step 6: The conveyor moves the product to the thickness measurement position, where the sensor checks the product.
• Step 7: The transfer mechanism moves the product into the product rotation and reorientation unit. This unit changes the position of the measured product and brings the next product into the measurement position. Products that meet the requirements are returned to the conveyor, while NG products are placed into the NG product box.
• Step 8: The product moves to the end of the conveyor. The sensor checks the product, and the operator removes it from the machine.
• Step 9: The cycle is repeated.

Thus, the shaft diameter and thickness measuring machine helps automate the inspection process, ensuring fast and accurate product quality control.

Key features of the automatic measuring machine manufactured by CNC VINA

Designed specifically for dimensional inspection, the shaft diameter and thickness measuring machine automates multiple processes, from positioning and measurement to product classification. The control system and measuring equipment are integrated into a synchronized system, providing fast inspection speeds, stable measurement results, and suitability for quality control requirements in production.

• The machine continuously performs the processes of moving products to the inspection position, positioning, measuring the diameter, measuring the thickness, and classifying the results. The operator mainly loads the products and removes them after the inspection cycle is completed, helping reduce manual operation time.
• Products are conveyed to the measuring positions by the conveyor and transfer mechanism according to a pre-programmed sequence. The measuring head performs dimensional inspections quickly, helping shorten the inspection time for each product and making the machine suitable for production lines requiring continuous inspection.
• Products are moved to the measuring position and accurately positioned before inspection. The measuring head is designed according to the characteristics of each workpiece, ensuring stable measurement and minimizing the effects of positional deviations during inspection.
• The system integrates a transfer unit and a product rotation and reorientation mechanism. After completing a measurement, the mechanism moves the inspected product out of the inspection position and brings the next product into position, allowing continuous inspection without requiring manual product orientation.
• After measurement, the system automatically processes the results according to the preset parameters and limits. Products that meet the requirements (OK) are returned to the conveyor, while products that do not meet the requirements (NG) are separated and placed into the NG product box, helping prevent confusion between OK and NG products.
• Sensors are installed at multiple positions on the machine to detect the presence of products and confirm their positions. The sensor system controls the operating sequence of the conveyor, transfer mechanism, and measuring units, while helping prevent the machine from performing an incorrect cycle when the product is not in the correct position.
• The touchscreen HMI is used to control and monitor the machine's operation. The operator can easily monitor the equipment status, perform control operations, and set the necessary parameters through an intuitive and convenient interface.
• The inspection results for diameter, thickness, and other related parameters are displayed on the LCD screen. Direct display of the results allows the operator to easily monitor measurement data, identify NG products, and control the operating status of the system.
