Detailed Explanation of High-Precision Grinding Methods for Double-Sided Surface Grinders During the grinding process, abrasive material is applied to the grinding tool, and grinding is performed using dispersed abrasive grains. In addition to sand, the abrasive mixture may also contain substances such as kerosene, machine oil, oleic acid, and stearic acid. As grinding proceeds, a layer of abrasive grains remains between the grinding tool and the workpiece, resulting in a surface roughness of Ra 0.04–0.02 μm. This method is typically used for rough machining, but the resulting surface tends to be relatively dull.
Detailed Explanation of High-Precision Grinding Methods for Double-Sided Surface Grinders
Double-sided grinding machine: a high-precision grinding process:
1. Dry grinding: During grinding, only a small amount of lubricating additive needs to be applied to the surface of the abrasive tool. The abrasive grains remain essentially fixed on the tool throughout the process, and the primary grinding mechanism is sliding abrasion. This method has relatively low productivity but can achieve high machining accuracy and very low surface roughness (Ra 0.02–0.01 μm).
2. Wet grinding: During the grinding process, abrasive material is applied to the grinding tool, and grinding is performed using dispersed abrasive grains. In addition to sand, the abrasive mixture contains substances such as kerosene, machine oil, oleic acid, and stearic acid. As a result, some abrasive grains remain between the grinding tool and the workpiece during machining, yielding a surface roughness of Ra 0.04–0.02 μm. This method is typically used for rough machining, but the resulting surface tends to be relatively dull.
3. Grind with soft abrasive grains
During the high-precision grinding process on a double-sided grinder, an abrasive coating containing chromium oxide is applied to the working surface of the grinding tool. Because the abrasive is softer than both the tool and the workpiece, it remains suspended between the workpiece and the tool during grinding. The chemical interaction between the abrasive and the workpiece surface primarily serves to form a soft oxide film; at asperity peaks, this film is readily removed by the abrasive. This approach enables the achievement of extremely fine surface roughness values (Ra 0.02–0.01 μm).
The crucial role of high-precision vibratory grinders in grinding and polishing
The operating principle of the high-precision vibratory grinder is based on the professional spiral‑turning flow and three‑dimensional motion, enabling the workpieces and the tumbling media to grind against each other. Our vibratory grinders are primarily used for surface grinding and polishing, edge deburring, chamfering, deflashing, rust prevention, rough polishing, fine polishing, mirror polishing, precision polishing, pre‑polishing, and electroplating—processes that many users have mastered. However, selecting the appropriate model of vibratory grinder can be challenging. Below, we provide a brief explanation based on the table below.
What role does a high-precision vibratory grinder play in the grinding and polishing field? Vibratory grinders can be categorized into automatic material-selection models and conventional models, so customers should choose based on their specific product requirements.
Vibratory grinders play a crucial role in grinding and polishing processes, serving applications such as bicycles, aluminum alloy die‑castings, zinc die‑castings, furniture hardware, apparel hardware, luggage and leather‑goods hardware, jewelry components, watch parts, locks, electronic components, various accessories, as well as powder metallurgy and epoxy resin products. They are also used for stamping, aluminum die‑casting, casting, and forging of materials like stainless steel sheets, iron, copper, zinc, aluminum, and aluminum‑magnesium alloys; and in fields such as deburring, edge finishing, chamfering, and parting‑line removal for cables, porcelain, jade, coral, anti‑corrosion coatings, plastics, and ceramics—areas where vibratory grinding is indispensable.
That’s all for today—no further explanation is needed. If you require high-precision grinding services, please entrust the work to our company.
