Working principle:
1. The grinding machine is a precision grinding and polishing equipment, the grinding and polishing materials are placed on the grinding disc, the grinding disc rotates against the clock, the correction wheel drives the workpiece to rotate, the gravity pressure on the workpiece, the workpiece and the grinding disc for relative running friction, to achieve the purpose of grinding and polishing.
2. The dressing mechanism of the grinding disc adopts the hydraulic suspension guide rail to move back and forth, and the diamond trimming knife trims the grinding surface of the grinding disc precisely to obtain the ideal plane effect.
Special points:
1. Usually, the traditional way of polishing plate is to use electroplate wheel to trim, which is not ideal. The error will be tens of microns or even hundreds of microns, through the dressing machine, grinding disc flatness can reach ±0.002mm. The flatness of the workpiece after processing can reach ±0.0005mm (φ50mm).
2. A series of grinding machine parts are pressurized by pressing the weight block.

FAQs
Q1: Which machine is most applicable for my product?
A: It usually depends on 5 requirements and parameters of your product: flatness, roughness, thickness, dimension, productivity:
1. If better flatness and roughness were required, you might need both lapping and polishing machine.
2. If to thin the product in a big margin, such as 500μm, you might need a thinner machine for extra.
3. If the productivity were excessive, you might need larger machine or to expand production line.
Additionally, we can confirm the production line as we make samples for you.
Q2: Does Ponda charge for making samples?
A: No, it's free to make samples.
Q3: Is Ponda trader or manufacturer?
A: We are manufacturer, certified National High-Tech Enterprise.
Q4: How long does it take machine to deliver?
A: Approximately 15 days to deliver. If the machine are out of stock, we need 15 days more to manufacture.
Q5: Does Ponda provide oversea setup and after-sale service?
A: Yes, we provide oversea service and online tutorial.
Q6: How many type of machine does Ponda manufacture?
A: We have 21 major series of machines, 5 different types run in different principles, more than 15 types of plates, 100 types of slurries.
