Product Description

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, SiC wafer, ceramics, glass, industrial sapphire, plastics, and any other composites.
Products Show
According to the process requirements of customers, the suction cups can be divided into electromagnetic suction cups and vacuum suction cups, the size of the suction cups can be customized according to customer needs, the diameter of 320-600mm.
The grinding wheel spindle adopts precision high-speed rotating electric spindle, and the driving mode is frequency conversion speed regulation. The speed can be changed according to different process requirements by the drive mode supported by the PLC control system. The speed is 3000-8000.
The grinding wheel feed mode is set in three stages, which makes it easier to set an effective thinning scheme and improve the precision and surface effect after thinning.
In the case of not changing the grinding wheel and suction cup, the workpiece with different thickness only needs to be set once to work continuously, and there is no need to set the knife every time.
The machine adopts high precision screw and guide rail components, the driving mode is servo drive, according to different materials of the workpiece and process requirements by the PLC controlled drive mode and the corresponding change of screw speed, that is, the grinding wheel feed speed, the speed is adjustable from 0.001-5mm/min, the control feed accuracy is detected by high resolution grating ruler.
This machine adopts advanced Taiwan brand PLC and touch screen, high degree of automation, man-machine dialogue, simple operation.

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.
