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.
ProductsW

Scope of application:
Widely used in LED sapphire substrate, all kinds of ceramic products, quartz wafers, silicon wafers, germanium wafers, molybdenum wafers, silicon carbide, lithium tantalate and other materials single-side polishing.



Equipment principle:
The polishing machine is a precision polishing equipment, the polished product is placed on the polishing disc, the polishing disc rotates against the clock, the workpiece rotates itself, the workpiece is pressed by the cylinder pressure, and the workpiece is relative rotating friction with the polishing disc to achieve the purpose of polishing.

 

Configuration and Advantages:
1. Automatic circulation liquid supply system is adopted.
2, the workpiece pressure using cylinder pressure, the pressure is adjustable; The cylinder has the function of preventing air loss to ensure personal and equipment safety.
3, using PLC+ touch screen control system, the rotation speed of the disc, air pressure and timing can be directly input on the control panel.
4, the equipment is set up a station (including a set of cylinder pressure), can be polishing 1 group of products at the same time.
5, with water cooling system, can cool the polishing liquid.
6, with the disc surface temperature measurement system, can be real-time temperature measurement of the disc surface, convenient temperature control, effectively prevent the temperature of the product caused by excessive damage.
7. The surface of the polished workpiece has the characteristics of high brightness, no scratch, no material grain, no pitting, no collapsing edge, etc.

APPLICATION

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.
