Description

Technical Field

[0001] The utility model belongs to the technical field of marble processing, and particularly relates to an extended guide wheel for marble cutting. Background Art

[0002] Marble, originally a white limestone with black markings found in Dali, Yunnan Province, is known for its striking polish. It's primarily used to shape various shapes and slabs for building walls, floors, platforms, and columns. It's also often used in monumental structures like monuments, towers, and statues. Marble can also be carved into practical artworks like arts and crafts, stationery, lamps, and utensils. Marble processing requires cutting, often done with a cutting machine. Guide wheels are a key component of these machines.

[0003] Existing extended guide wheels for marble cutting typically use glue to attach the guide wheel's end cap to the shaft's connecting barrel. This fixing method is prone to misalignment over time, causing the guide wheel to disassemble. It also makes it difficult to replace guide wheels of different sizes based on user cutting needs. Therefore, we needed to upgrade and modify the existing technology. Utility Model Content
