  CMM Calibration for 2-Dimensional Motion TablesA Key to High-Quality Precision Positioning In precision manufacturing, rotary positioning tables are extensively used in machine tools, automation equipment, and precision machining processes. The accuracy of a two-dimensional (2D) motion table significantly impacts overall production quality and repeatability.Traditionally, the industry relies heavily on laser measurement systems for calibration. However, in specific high-precision applications, Coordinate Measuring Machines (CMM) offer a more detailed and visual inspection method.  What is a CMM, and why use it? A CMM (Coordinate Measuring Machine) uses contact probes or optical sensors to measure the geometric shape and dimensions of a component. It accurately captures X, Y, and Z coordinate data, effectively measuring flatness, parallelism, hole positioning, depth differences, and other critical geometric features.  Why do we use CMM in addition to laser inspection？ Laser inspection provides rapid and non-contact measurements suitable for quickly detecting overall contour deviations. However, when it comes to pinpointing subtle deviations in specific positions during 2D rotational movement, especially in parallelism or perpendicularity, laser methods alone may not provide sufficient detail.In these cases, the CMM offers another highly effective solution. With its touch probe system, it precisely measures individual coordinate points, capturing detailed data that laser methods might overlook, enabling comprehensive verification of accuracy throughout table movement. Herbao Machinery’s Rotary Table CMM Calibration Procedure Step 1: Equipment Setup and Establishing Reference PointsThe rotary positioning table is firmly mounted on the CMM’s measuring table. Reference points are established to ensure consistent and accurate subsequent measurements.Step 2: Probe Positioning and Initial CalibrationA highly precise measuring probe locates and records the established reference points on the table’s surface, generating an accurate baseline data model.Step 3: Sequential Angle MeasurementThe table is incrementally rotated, typically by 15 degrees per step. After each rotation, the probe measures again, comparing the targeted angle against actual measurement data to verify rotational positioning accuracy.Step 4: Real-time Data AnalysisMeasurement data is instantly relayed to the computer, where software analyzes precision, ensuring parameters such as flatness, perpendicularity, and concentricity remain within permissible tolerances.Step 5: Comprehensive Data ReportingUpon completing all angle measurements, the CMM generates a detailed inspection report, which serves as a key reference for quality control and analysis, ensuring that the rotary positioning tables consistently meet the highest standards.  Real-World Applications The accuracy of two-dimensional motion tables is critical in industries such as high-precision component manufacturing, PCB drilling, semiconductor packaging, and medical device production. For instance, automated alignment and bonding systems operating without stringent calibration may result in slight inaccuracies, significantly increasing production line defect rates.  Conclusion  The introduction of CMM measurement technology not only enhances the reliability of rotary positioning tables but has become a crucial verification method in the precision machining industry. Herbao Machinery employs this technology to effectively ensure equipment quality, providing industry users with increasingly precise and stable solutions.Video Demonstration  Herbao Machinery continues to pursue technological innovation, providing customers with professional and reliable solutions.For technical inquiries or further information, please contact us! https://www.herbao.com.tw/en/hot_515084.html Knowledge Sharing #7 - Rotary Positioning Table Calibration: CMM as an Alternative to Laser Inspection 2025-05-16 2026-05-16

Home Information Knowledge Sharing Issue #2 High-Precision, High-Inertia, High-Rigidity Rotary Transmission Methods [2024-06-13]

An Overview of Transmission Methods in Rotary Mechanisms

Currently, the transmission methods for rotary mechanisms include hypoid gears, worm gears, helical gears, direct drive motors, roller gears, harmonic reducers, etc., each with its own advantages and disadvantages.

Hypoid Gears

Hypoid gears are gears with an offset axis added to a spiral bevel gear. Compared to spiral bevel gears, hypoid gears can achieve a high reduction ratio and high strength, with relatively low noise.

 

Hypoid gears are typically used in applications requiring high precision and smooth transmission, such as precision machinery, high-speed transmission systems, and precision instruments. The special gear design effectively reduces tooth surface pressure and gear tooth wear, enhancing the service life and reliability of the transmission system.

Hypoid gears are designed to be lightweight and compact, without being constrained by space limitations. The use of high-strength materials ensures stability and reliability in high-pressure, high-load environments. These gears operate smoothly with low noise, have relatively low production costs, and are highly efficient. They are widely used in automotive and truck differentials, as well as in machine tools.

 

Application Example

Hypoid Gear Digital Control Rotary Positioning Table

The Digital Control Rotary Positioning Table uses hypoid gears as the transmission method to achieve high precision, high rigidity, and high inertia, enabling five-axis linkage surface process motion modules.

Hypoid Gear Digital Control Rotary Positioning Table can be used in optical inspection, automated multi-station applications, lathe applications, grinding applications, robotic arms, automotive industry applications, machining applications, honing machines, etc.

 

Helical Gears

Helical gears consist of two or more gears with teeth arranged at an angle, typically between 10° and 45°. The angled design allows for smoother operation, as the gear teeth engage gradually, reducing impact and noise during meshing.

Helical gears are commonly used in mechanical systems requiring high precision and smooth motion, such as vehicle transmissions, machine tool drive systems, and industrial robots.

 

Worm Gears

Worm gears consist of a helical worm and a matching worm wheel. They can be used for position positioning devices and rotational tables in machinery, as well as power transmission devices. Common applications include high-ratio reducers, machine tool rotational positioning, handling positioning machines, and elevator hoists, or for changing the direction of power.

The worm gear transmission system operates through sliding contact. A single pair of gears can achieve a high reduction ratio, is integrally formed with high strength, produces low noise, and has self-locking capability.

 

▼ Comparison Chart of Various Gear Characteristics

 Worm gears made in Japan use carbon steel and alloy steel for the worm shaft, which are relatively hard. To prevent surface abrasion, the worm wheel uses softer materials such as phosphor bronze and aluminum bronze.

 

Direct Drive Motors

Direct drive motors are motor systems directly connected to the load, without using a transmission system (such as a reducer or drive belt). They can directly convert motion into torque, offering advantages such as high precision, high speed, high torque density, and low noise.

Roller Gear Cam

The roller gear cam is used to convert rotational motion into linear motion. It consists of gears with raised teeth and rollers. The gear surface usually has a specific shape, such as an arc, ellipse, or other, depending on the required motion path. The rollers are small cylindrical elements that can roll on the gear surface.

Harmonic Reducers

Harmonic reducers achieve reduction effects using harmonic gear principles. They consist of three main components: the input shaft, harmonic generator, and output shaft. The input shaft drives the harmonic generator to produce harmonic motion, which is then transmitted to the output shaft, achieving the reduction effect.
