Description

A cutting tool for cutting arc edges

technical field

The present invention relates to a connector, in particular to a cutting tool for cutting arc edges.

Background technique

Panel furniture plywood (plywood) is often used to make furniture that needs to be bent and deformed; the performance of blockboard is sometimes affected by the material of the board core; particleboard (also known as particle board, bagasse board) is loose in material and is only used for low-end furniture. The most cost-effective and most commonly used is medium density fiberboard (MDF). Common finishing materials for panel furniture are veneer (commonly known as veneer), wood grain paper (commonly known as stickers), PVC plywood, polyester lacquer (commonly known as baking varnish), etc.

Common man-made boards include Hexiang board, plywood, blockboard, particleboard, MDF, etc. The combination of panel furniture is usually connected by various metal hardware, which is convenient for transportation. Because the base material breaks the original physical structure of wood, when the temperature and humidity change greatly, the deformation of wood-based panels is much better than that of solid wood. The quality is more stable than that of solid wood furniture.

Common finishing materials for panel furniture are veneer, melamine impregnated paper, wood grain paper, PVC plywood, polyester lacquer, etc. The latter four finishes are typically used for low- and mid-range furniture, while natural veneer finishes are used for high-end products. Panel furniture is furniture made of medium density fiberboard or particleboard with surface veneer and other processes. A large part of this kind of furniture is wood grain simulation furniture. The veneers of some panel furniture sold on the market are becoming more and more realistic, with good gloss and feel, and the products with fine craftsmanship are also very expensive. Due to the use of solid wood veneer, the natural veneer veneer is more difficult to maintain, and the wear resistance of the veneer, high temperature resistance and water resistance, is much worse than that of the melamine veneer.

In the production process, for the sake of the aesthetics or practicality of the furniture, it is usually necessary to perform arc edge processing on the panels of the furniture. However, in the process of processing, in order to ensure the precision of the chips, a special fixture is usually required to ensure the cutting amount. The fixture is not only large, but also In addition, the cost is high, and the corners of the plate cannot be cut accurately.
