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 is applied to the workpiece, and the workpiece and the grinding disc are subjected to relative running friction to achieve the purpose of grinding and polishing.
2. The disc repairing machine uses the hydraulic suspended guide rail to move back and forth, and the diamond shaving knife trims the grinding disc precisely, so that the grinding disc gets precise flatness.
The timing function is used to control the time. When processing products, the time and speed can be set in advance on the panel, and the working time will jump to the set time. The machine will automatically stop working, and the product size can be better controlled.

The grinding machine parts are pressurized by pressing the weight of the weight block, and the surface brightness of the polished workpiece is high, no scratch, no scratch, no material grain, no pitting, no collapsing edge, and high flatness. After polishing the workpiece surface roughness can reach Ra0.002;

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.
