Ⅵ.Material processing

Next is the material processing link, this link mainly includes black walnut cutting, carving, grinding and painting four major processes^[13].

1.Cutting

When cutting black walnut, it is necessary to consider the moisture content and dryness of it to avoid cracks or deformation during the cutting process. In addition, the choice of cutting tools and operating skills will also affect the cutting efficiency and black walnut processing quality. The appropriate cutting method can not only improve the utilization rate and beauty of the black walnut, but also extend the service life of the product.

Preliminary Cutting

Rough Cutting: In the preliminary cutting stage, logs are cut into larger sized boards or squares. This process is usually carried out in sawmills, using large band saws or circular saws.
Debarking and Trimming: Remove the bark and rough parts of the edges to ensure a flat surface of the wood and prepare for subsequent fine cutting.

Fine Cutting

Fine Cutting: In the fine processing stage, the wood is finely cut according to the design requirements. This stage requires the use of high-precision cutting equipment such as precision circular saws, table saws or CNC routers.
Cutting Method: Choose the appropriate cutting method according to your needs, such as flat sawing, quarter sawing or miter sawing. Flat sawing can show the natural texture of the wood, while quarter sawing and miter sawing can achieve more unique texture effects

2.Carving

Black walnut carving is a kind of traditional handicraft that transforms black walnut into works of art. It transforms wood into figurative or abstract sculpture works through the sculptor's careful carving and shaping of wood. black walnut carving can be divided into two categories: three-dimensional carving and plane carving.

3.Grinding

Black walnut grinding is an important process in the black walnut processing process, it can remove burrs, stains, scratches and uneven coating on the surface of the wood, make the surface of the wood smoother and smoother, and lay a good foundation for the subsequent coating, painting or pasting work.

4.Painting

Black walnut painting is a process that protects the surface of wood and enhances its durability and aesthetics. Not only does painting protect the wood from moisture, insects, UV radiation and other environmental factors, it also enhances the appearance of the wood, making it more decorative and practical.
