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.Product DescriptionProducts ShowPrinciples and Features of the Equipment 1. This grinding machine is a precision grinding equipment. The product to be ground is placed on the grinding disc, and the grinding disc rotates counter - clockwise while the workpiece rotates by itself. Grinding is achieved by applying pressure with gravity to press the workpiece against the grinding disc, and the relative rotation and friction between the workpiece and the grinding disc. 2. The grinder adopts oil - pressure floating guide rails and cooperates with diamond dressing tools to precisely dress the grinding disc, enabling the grinding disc to obtain a precise flatness. 3. Frequency conversion control is adopted to realize soft start, soft stop, low impact force, and reduced workpiece damage. 4. This series of grinding machines use PLC program control and touch - screen operation panel. The rotation speed of the grinding disc, timing, and grinding time can be directly input on the touch - screen, and the speed is adjustable, making operation convenient. 5. Imported reduction motors are used to ensure the stability and service life of the equipment and meet the precision requirements of the workpiece. 6. The pressure of the grinding machine's workpiece is applied by cylinder - driven tappet lifting and pressing. After grinding, the surface flatness of the workpiece can be controlled within the range of ± 0.002mm (φ200mm). 7. The workpiece disc has the function of active driving by a reduction motor, with adjustable speed, and three stations can be independently controlled. 8. The equipment is equipped with three stations, allowing simultaneous polishing and grinding of three groups of products. 9. Grinding fluid (or coolant) circulation and filling system.APPLICATIONProcessIndustry by SubstanceIndustry by ApplicabilitySinglePlateLapping& PolishingMetal And AlloyCeramicOxideCarbideGlassPlasticNature StoneSealingvalve and sealing ring(liquid, oil, gas)SemiconductorLED substrate(Al2O3, Si, SiC)wafer substrate(Si, SiC, Ge, Ge-Si, GaN, GaAs, GaAsAl, GaAsP, InSb, ZnO, AlN)PlasticPE, E/VAC, SBS, SBR, NBR, SR, BR, PRPhone Frame(flat)back platePCBadhesive, coating, circuitOptics(flat)optical lens, optical reflector, scintillator cube, holographic glass, HUD glass, screen glassRadaroxide coating plateGemstonejade, sapphire, agate, etc.Othersgraphite 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 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.
