High Precision Flat Lapping Mould Machine

Equipment Use:

High precision surface lapping machine is suitable for single surface lapping and polishing of high precision large mould and mass production of small mould. For example: plastic mold, mold steel, stainless steel plate, seal valve sheet, oil drilling with diamond drill bit.

Working Principle:

1. This equipment is a precision polishing equipment, which is ground and put on the lapping plate by throwing the mold. The lapping plate rotates against the clock, the correction wheel drives the mold to rotate, the pressure cylinder puts pressure on the mold, and the mold and the lapping plate make relative running friction to achieve the purpose of lapping and polishing.

2. Lapping disc dressing mechanism adopts oil pressure suspension guide rail reciprocating back and forth, diamond shaving knife for lapping disc lapping surface precision dressing, get ideal plane effect.

Equipment Features:

1. The flatness of lapping disc can reach ±0.0002mm; The workpiece with a diameter of 50mm can reach 1/4 wavelength after processing.

2. This series of polishing machine products lapping pressure mode is: pressure block pressure or cylinder pressure, the pressure is adjustable;

3. This series of polishing machine adopts button control or PLC process near control system, the speed is adjustable, easy to operate.

4. The lapping disc adopts water cooling circulation system, the temperature can be controlled in the low temperature state, the error of ±1℃ to solve the problem of heat generated in the process of lapping workpiece deformation.

Equipment Specifications:

The company’s main equipment: flat lapping machine, flat polishing machine, double-sided lapping machine, mirror polishing machine, wire drawing machine, edge sweeping machine, etc.

The company's main consumables: lapping discs, brush wheels, brush discs, blanket discs, polishing leather, polishing belts, sponge sand, scouring pads, etc.

Fixtures and accessories, powder metallurgy molded parts, etc.

The best way to use surface lapper:

1. Mechanical clamping method

Using the flat-nose pliers in the attachment of the surface grinder to suck the thin piece work piece by the magnetic workbench, the flat-nose pliers have a certain height, so the magnetic force on the jaws is small. Use the method of gradually reducing the feed rate to grind one flat surface of the thin workpiece and then remove it. At this time, put the ground surface on the magnetic table, and then grind the other surface of the thin workpiece, and repeat the grinding several times. , The flatness of the two planes meets the requirements.

2. Clamping method of cushion elastic gasket

The first brand of surface grinder analyzes the elastic clamping mechanism when grinding the above-mentioned thin workpieces on a surface grinder, so that the thin workpieces can be positioned and clamped in a free state. A layer of 0.5mm thick rubber is placed between the workpiece and the magnetic worktable. When the workpiece is subjected to magnetic attraction, the rubber is compressed and the elastic deformation becomes smaller, so that the flat surface of the workpiece can be ground. Repeated grinding several times can meet the requirements of machining accuracy.

3. Use temporary measures to strengthen the rigidity of the thin workpiece

Using epoxy resin bonding agent, the sheet workpiece is glued to a flat plate in a free state. The plate is placed on the magnetic chuck together with the sheet. After the flat surface of one end of the sheet is smoothed, the sheet workpiece is removed from the flat plate, and the flat side is placed on the magnetic chuck, and the other end of the sheet workpiece is ground. Since the epoxy resin has fluidity before hardening, it can fill the gap between the thin workpiece and the flat plate. When the epoxy resin is hardened, the workpiece and the plate are bonded together to form a whole, thereby greatly enhancing the rigidity of the workpiece. Under the magnetic attraction, the thin workpiece will not be clamped and deformed, which creates conditions for grinding a flat surface. Thick grease can also be used instead of epoxy resin to fill the gap between the sheet workpiece and the magnetic chuck to enhance the rigidity of the workpiece, and good results can also be obtained.
