High precision grinding machine features:
1. Using interval automatic spray device, spray interval time can be set freely. Its working principle is that the stirring start-up grinding liquid can automatically flow through the drop pipe to the grinding disc, and the flow rate can be adjusted according to the requirements (see the specific adjustment of the drop pump manual).
2. 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. The flatness of the workpiece after processing can reach ±0.0005mm
3. The grinding machine can be pressurized by pressing the weight block, and the pressure is adjustable [Microsoft user 1];
4. The series grinding machine adopts the switch press and twist control system, and the rotation speed and timing of the grinding disc can be directly set on the control panel.
APPLICATION

Process	Industry by Substance	Industry by Applicability
Single Plate Lapping & Polishing	Metal And Alloy Ceramic Oxide Carbide Glass Plastic Nature Stone	Sealing	valve and sealing ring(liquid, oil, gas)
		Semiconductor	LED substrate(Al2O3, Si, SiC) wafer substrate(Si, SiC, Ge, Ge-Si, GaN, GaAs, GaAsAl, GaAsP, InSb, ZnO, AlN)
		Plastic	PE, E/VAC, SBS, SBR, NBR, SR, BR, PR
		Phone Frame(flat)	back plate
		PCB	adhesive, coating, circuit
		Optics(flat)	optical lens, optical reflector, scintillator cube, holographic glass, HUD glass, screen glass
		Radar	oxide coating plate
		Gemstone	jade, sapphire, agate, etc.
		Others	graphite block, gauge block, micrometer gauge, diamond, friction plate, knife, bearing, metal components, and any other precise hardware.
*NOTE: lapping can only remove slight thickness of workpiece. If need ultra thinning (≤100μm), thinner machine are needed.

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.
