In terms of precision detection, it clarifies the detection methods and tolerance ranges of various precision indicators of planers, such as geometric accuracy, positioning accuracy, and repeated positioning accuracy.
For example, for the geometric accuracy detection of planers, the standard specifies how to detect the flatness, straightness, verticality of the planer’s work surface, and other geometric accuracy items, and gives the corresponding tolerance values ​​to ensure that the geometric accuracy of the planer meets the requirements, thereby ensuring the geometric shape accuracy of the processed parts.
ISO 7571:1986 “Woodworking Machine Tools Planer Terminology and Acceptance Conditions”
Mainly applicable to woodworking planers, it specifies the terminology and precision requirements of woodworking planers, and provides a unified technical basis for the design, manufacture, inspection and acceptance of planers. This standard is equivalent to GB/T 13569-2008 in my country, which promotes the standardization and international development of the woodworking planer industry.
The standard specifies the geometric accuracy inspection items and tolerances of woodworking planers, such as the flatness of the worktable, the axial and radial runout of the planer shaft, etc., to ensure that the woodworking planer can meet the precision requirements of wood processing.
ISO 3070-4:1998 “Test conditions for horizontal spindle boring and milling machines – Precision test – Part 4: Planers with movable columns”
Mainly focuses on the precision test of drilling and milling machines using horizontal spindles, of which the fourth part is specifically for the precision test of horizontal flat-bed planers with movable columns. The test content includes machine layout and layout accuracy, measurement system and analysis method, operating stability, environmental conditions, repeatability and reproducibility, etc.
For example, the standard requires that during the test, the operation of the machine tool must remain stable to avoid vibration and abnormal noise that interfere with the measurement results. At the same time, multiple tests are specified to evaluate the repeatability and reproducibility of the machine tool to ensure the accuracy and reliability of the test results, thereby comprehensively evaluating the precision performance of the planer.

Main items of planer precision detection
Geometric precision detection
Flatness of the worktable: By placing a marble ruler or flat plate on the worktable, and using a level or other measuring tools to detect the flatness error of the worktable at different positions, ensure the flatness of the worktable, and provide stable support for the processing of the workpiece.
Straightness of the guide rail: Use measuring tools such as laser interferometers or levels to detect the straightness error of the planer guide rail in the horizontal and vertical planes. The straightness of the guide rail directly affects the motion trajectory of the planer, and then affects the straightness and surface roughness of the processed parts.
Verticality of the tool holder: Use a square or laser measuring tool to detect the verticality error of the tool holder relative to the worktable. The verticality of the tool holder is crucial to ensure the verticality and shape accuracy of the processed parts. For example, when processing step surfaces or grooves, the verticality of the tool holder will affect the verticality and parallelism of the processed surface.
Positioning accuracy detection
Longitudinal and lateral positioning accuracy of the worktable: Use measuring instruments such as laser interferometers or grating rulers to detect the positioning accuracy of the worktable when it moves longitudinally and transversely. The positioning accuracy of the workbench determines the position accuracy of the processed parts. For example, when processing multiple holes or slots, the positioning accuracy of the workbench will affect the distance accuracy and position accuracy between the holes or slots.
Vertical lifting positioning accuracy of the tool holder: By measuring the positioning accuracy of the tool holder when it moves in the vertical direction, ensure that the tool holder can accurately reach the set processing position, improve processing accuracy and consistency, and reduce processing errors.
Repeat positioning accuracy detection
Repeat positioning accuracy of the workbench and tool holder: Let the workbench or tool holder move to the same set position multiple times, use the measuring tool to detect the deviation between the actual arrival position and the set position each time, and calculate its repeat positioning accuracy. Repeat positioning accuracy reflects the ability of the planer’s moving parts to return to the same position after multiple moves, which is of great significance for ensuring the consistency and repeatability of parts when processing batch parts.
Methods and processes for planer accuracy detection
Preparation before detection
Equipment inspection: Conduct a comprehensive inspection of the planer, including power supply, air source, hydraulic system, lubrication system, etc., to ensure the normal operation of the equipment and no hidden troubles. At the same time, check whether the instruments and tools required for detection are complete and intact, and calibrate and adjust them to ensure the accuracy of the measurement results.
Working environment control: Place the planer in an environment that meets the standard requirements, such as temperature, humidity, cleanliness, etc. Generally speaking, the temperature of the testing environment should be controlled at around 20℃, and the humidity should be kept between 40% and 60%. Avoid direct sunlight and strong wind interference to reduce the impact of environmental factors on the test results.
Preparation of workpieces and tools: Select appropriate workpieces and tools according to the test items and requirements. The workpiece should be representative and able to reflect the processing accuracy of the planer; the tool should meet the relevant standard requirements, with sharp edges, no wear and damage.
Testing process
Geometric accuracy detection: According to the geometric accuracy detection items and methods mentioned above, use the corresponding measuring tools to detect the various geometric accuracy indicators of the planer, and record the measurement data. During the detection process, the steps and methods specified in the standard should be strictly followed to ensure the accuracy and repeatability of the measurement results.
Positioning accuracy and repeat positioning accuracy detection: Use laser interferometers, grating rulers and other measuring instruments to detect the positioning accuracy and repeat positioning accuracy of the workbench and tool holder. When testing positioning accuracy, multiple measurements should be performed at different positions and speeds, and the average value should be taken as the final measurement result; when testing repeated positioning accuracy, multiple repeated measurements should be performed, and statistical quantities such as standard deviation or range should be calculated to evaluate its repeated positioning accuracy.
Processing and analysis of test results
Data processing: The large amount of data obtained during the test process is sorted and analyzed, and the statistical quantities such as the average value, standard deviation, maximum error, minimum error, etc. of various accuracy indicators are calculated, and compared with the tolerance range specified in the relevant standards.
Result evaluation: According to the data processing results, the accuracy of the planer is evaluated. If all accuracy indicators are within the standard tolerance range, it means that the accuracy of the planer is good and can meet the processing requirements; if some accuracy indicators exceed the tolerance range, the planer needs to be adjusted and repaired to find out the problem and take corresponding measures to solve it.
