Why Ponda?
Ponda has profound experience of lapping, polishing and thinning. We heretofore supplied more than 60, 000 lapping process solutions and appliances over the industries of machinery, electronic, aerospace, aviation, automotive, atomic energy, optics; the substances of metal, wafer substrate, ceramics, glass, industrial sapphire, plastics, and any other composites.
Main purpose:
This grinder is suitable for single plane grinding and polishing of high-precision large workpieces and mass production of small workpieces. For example: sapphire, optical glass, aluminum alloy, stainless steel, light guide plate, ceramic, valve plate, diamond drill bit for oil drilling, etc
Working principle and characteristics
equipment
Working principle:
1. This grinder is a precision grinding equipment, where the product being ground is placed on a grinding disc. The grinding disc rotates counterclockwise and the workpiece rotates on its own. The workpiece is pressurized by gravity and subjected to relative rotational friction with the grinding disc to achieve the grinding purpose.
2. The disc repair machine adopts an oil pressure suspension guide rail, which is combined with a diamond trimming knife to perform precise trimming on the grinding disc, resulting in a precise flatness of the grinding disc.

Equipment features of high-precision grinding machine (with water-cooled surface grinding machine):
1. The flatness of the grinding disc can reach ± 0.002mm; The flatness of the workpiece with a diameter of 50mm can reach 1/4 wavelength after processing.
2. The workpiece of this grinder can be pressurized using a weight block, and the pressure can be adjusted;
3. The series grinding machine adopts PLC program control, with a touch screen operation panel. The number of revolutions, timing, and grinding time of the grinding plate can be directly input on the touch screen, and the speed can be adjusted, making it easy to operate
4. The grinding disc adopts a water-cooled circulation system, which can control the temperature at a low temperature state with an error of ± 1 ºC, solving the problem of heat generated during the grinding process and causing deformation of the workpiece.
The gravity actuator cylinder has a protective locking function (i.e., it can maintain its original state when power is cut off)
5. The equipment is equipped with three workstations (including three sets of weighing and self-locking systems), which can simultaneously perform polishing and grinding processing of three sets of products.
6. Grinding fluid (or coolant) circulation filling system

FAQ
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.
