Doudle-sidelapping Machine

Main Application：

This polishing machine is suitable for single-side polishing of large high-precision workpieces and mass production of small workpieces.

Examples include materials such as aluminum alloys, stainless steel, tungsten steel, light guide plates, ceramics, silicon wafers, sapphire, valve plates, and diamond drill bits for oil drilling (covering both metal and non-metal materials).

Working Principle and Features：

Gantry Structure: Adopts a gantry structure, featuring more scientific stability and a long service life.

AC Variable-Frequency Motor Drive: Driven by an AC variable-frequency motor, it enables soft start and soft stop, ensuring stable and reliable operation.

Four-Stage Pressure for Lapping: The lapping machine adopts a four-stage pressure operation process, namely light pressure, medium pressure, heavy pressure, and finishing pressure.

Button-Type Operation & Variable-Frequency Speed Regulation: This series of lapping machines uses button-type operation and variable-frequency speed regulation. The motor speed and running time can be directly input on the control panel.

Independent Slow-Descending Cylinder for Upper Plate: The upper plate is equipped with an independent slow-descending cylinder, which not only effectively prevents the breakage of thin and brittle workpieces but also allows independent pressure control.

Precise Control via Electronic Preset Counter: By using an electronic preset counter, the number of lapping cycles and requirements can be accurately controlled.

Lapping Plate Finishing with Trimming Machine: The lapping plate can be finished using a trimming machine. The trimming machine adopts a hydraulic suspension guide rail for front-and-back reciprocating movement, and cooperates with a diamond trimming tool to perform precise finishing on the lapping plate, ensuring the lapping plate achieves high-precision flatness.

Large-Size Drive Shaft Design: The drive shaft adopts a large-size design, which enhances the shaft rigidity and thereby eliminates vibration caused by insufficient rigidity.

Independent Drive for Upper/Lower Lapping Plates and Sun Gear: The upper lapping plate, lower lapping plate, and sun gear are all equipped with independent drive devices, allowing separate speed regulation and direction adjustment.

Added Weighing System & Pressure Control Functions: Equipped with a weighing system, linear pressure control function, and real-time pressure monitoring function.
