In the field of mechanical manufacturing, plug gauges are used as high-precision measuring tools to measure parameters such as the aperture size of workpieces, and plug gauge grinders are key equipment to ensure the accuracy and quality of plug gauges. For those who are new to this field, it is necessary to have a comprehensive understanding of the relevant knowledge of plug gauge grinding machines. The following will explain in detail from selection points to daily maintenance skills.

1、 Selection considerations

1. Processing accuracy requirements

The precision requirements for plug gauges vary significantly in different application scenarios. If used for the detection of blade holes in aerospace engines, a grinder that can achieve micrometer or even sub micrometer machining accuracy should be selected; For the production of plug gauges for ordinary mechanical parts, nanometer level accuracy is usually sufficient to meet the requirements. High precision grinding machines are often equipped with more precise spindle systems, guide rails, and CNC systems, and the cost is relatively high, so it is necessary to plan a reasonable budget range based on the actual product accuracy.

2. Production scale adaptation

On a large-scale production line, in order to ensure efficiency, it is recommended to choose a product with high automation, multi axis linkage, and fast changeover functionPlug gauge grinderIt can process multiple plug gauges simultaneously or switch between different specifications of plug gauges in a short period of time; Small batch customized production focuses on the flexibility and universality of equipment, while manual or semi-automatic grinding machines are more suitable due to their lower purchase costs and simple operation modes. Operators can adjust parameters at any time to cope with diverse orders.

3. Process capability matching

Select grinding machines with appropriate processing capabilities based on plug gauge materials and design requirements. Hard alloy plug gauges have high hardness and require grinding with diamond grinding wheels; The rules for ceramic plugs should consider their brittle characteristics and be equipped with special protective devices and equipment for fine grinding processes to prevent problems such as edge breakage and cracks during processing that may affect the quality of the finished product.

2、 Key points of daily maintenance

1. Cleaning and maintenance

It is crucial to promptly clean the metal debris, dust, and other impurities on the grinder after daily work. First, use a specialized brush to clean the exposed parts, and then use compressed air to blow away any residue in the gaps to prevent debris from entering the transmission components and accelerating wear or causing malfunctions; Regularly remove the protective cover and thoroughly clean key internal components such as screws and nut pairs to ensure smooth and unobstructed movement.

2. Lubrication management

Good lubrication of sliding and rotating parts is the foundation for maintaining the accuracy of the grinder. Strictly follow the time intervals and lubricant requirements specified in the equipment manual to add grease. For high load operating components such as spindle bearings, high-performance grease should be used and the amount should be precisely controlled. Excessive grease can easily leak and contaminate the workpiece, while insufficient grease cannot effectively lubricate and cause heating damage.

3. Accuracy monitoring and calibration

Periodically using precision measuring instruments (such as laser interferometers) to check and verify the positioning accuracy and repeatability accuracy of the grinder. Once deviations are found to exceed the allowable range, compensation and correction should be made immediately according to the manufacturer's provided debugging process; After each replacement of the grinding wheel or tool, it is also necessary to re align the tool and perform zero point reset on the relevant coordinate axes to ensure the accuracy of subsequent machining dimensions.

4. Component inspection and replacement

Regularly inspect electrical circuits for damage and aging, and check for loose joints to prevent leakage and short circuit accidents; Pay attention to the tightness and wear condition of the belt transmission system, adjust the tension or replace the belt in a timely manner; For vulnerable parts such as filters and seals, the inspection cycle should be shortened, and deteriorated components should be replaced in a timely manner to prevent the entire equipment from being shut down for maintenance due to minor losses.

In short, mastering the correct selection method for plug gauge grinders and strictly implementing daily maintenance standards can not only improve the quality and efficiency of plug gauge manufacturing, but also extend the service life of equipment, reduce production costs for enterprises, and help them stand out in fierce market competition.
