*Explanation in the video! Grinding device Super Finisher Flat Grinding*

*Explanation in the video! Grinding device Super Finisher Flat Grinding*

For polishing various substrates and for fine burr removal in punched areas.

Super Finisher flat surface grinding allows even beginners to subtly differentiate the use of laps on the back side of the stamper original plate, and the environment is clean. The stamper back surface grinding device polishes the back side of the stamper using a lapping film. The clamping and unclamping of the workpiece is done by the operator, while roll grinding, pad grinding, brush cleaning, and air blowing are performed automatically. The various surface roughness requirements from different companies can be processed under optimal conditions by selecting the appropriate lapping tape and changing the parameters of the device. *Features* 【Stamper Back Surface Grinding Device】 - Various surface roughness requirements from different companies can be processed under optimal conditions by selecting the appropriate lapping tape and changing the parameters of the device. - The circumference of the roll grinding can be randomized with pad grinding. - Once the conditions are set, even beginners can operate it easily. 【Thin Plate Flat Surface Grinding Device】 - The film width can be selected according to the workpiece (supports two types), achieving high efficiency and low-cost processing. - Effective for polishing various substrates and removing fine burrs from punched parts. - If a sub-table is provided, external setup can be done during processing time. *For more details, please download the materials or contact us.*

Difficult-to-cut material processing case: Thin plate grinding

Difficult-to-cut material processing case: Thin plate grinding

Hastelloy (C-22) plate! The processing involves repeated surface grinding on one side.

We would like to introduce a processing case of "thin plate polishing" conducted at Aitec Co., Ltd. This case involves a Hastelloy (C-22) plate measuring 3×305×355, with a thickness tolerance of ±0.02mm and geometric tolerances for flatness and parallelism within 0.03mm. The processing was done through surface grinding, repeatedly polishing one side. Unlike conventional clamping methods, we used a different clamping technique to finish the reference surface, and then clamped the opposite side to prevent the workpiece from warping during finishing. [Case Overview] ■ Material: Hastelloy ■ Size: 3×305×355 ■ Processing Details: Surface Grinding *For more details, please refer to the PDF document or feel free to contact us.
