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.
Scope of application:
This equipment is mainly used for thinning of silicon wafer, gallium arsenide, silicon carbide ceramics, zirconia ceramics, sapphire and other substrate materials.
Vertical cutting grinding.

Equipment structure:
The equipment is mainly composed of frame, air spindle, porous ceramic suction cup (suitable for various types of tension rings), vacuum spindle deceleration motor, static pressure air suspension electric spindle, diamond grinding wheel,
Screw guide module, full closed loop servo control system, cutting fluid circulation system, etc.

Equipment characteristics
1. The vacuum spindle is made of 603 stainless steel material, which is not easily affected by thermal expansion and leads to the precision of grinding size, and the bearing is made of AFK brand.
2. Vacuum suction cups are divided into microporous ceramic suction cups and special stainless steel gas slots, which can be selected according to product requirements.
3. The vacuum spindle is driven by precision reducer and servo motor.
4. The rotor of the static pressure gas suspension spindle adopts zirconia ceramic, which completely avoids the heat transmitted from the motor to cause the gas film gap to be too large after the expansion of the air float rotor and reduces the rigidity of the spindle. The equipment using the spindle has high precision and good stability.
5. Screw guide module adopts high precision and high preloading type.
6. Full closed-loop grating control system: In order to ensure the servo motor to the precision of the grinding wheel feed monitoring and repair, with the cooperation of this system, the product processing accuracy can be within 0.002mm.
7. Grinding fluid circulation system: The grinding fluid in the production process continues to cool the workpiece, grinding wheel and electric spindle through the circulation system, and the grinding fluid can also improve the self-sharpness of the grinding wheel.
8. Note: The equipment can be optional contact online detection system, online size measurement system using Marposs and other brands of contact online measuring instrument, the resolution can reach 0.1um, the actual control size accuracy can reach 0.5um.

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.
