1. Preparation before grinding the handle

Before choosing a grinding wheel, ก่อนอื่นคุณต้องกําหนดสภาพพื้นผิวเริ่มต้นของที่จับ, และเตรียมเครื่องมือที่จําเป็น, such as grinding wheel, acrylic paint, glue, ฯลฯ. The surface of some newly bought knives may already be very smooth. At this time, it needs to be slightly polished with a grinding wheel above 320 mesh to remove the original coating or paint and provide a certain roughness for the subsequent coating.

2. Select the number of grinding wheels according to your needs

Grinding the tool handle requires selecting the appropriate mesh size based on the initial surface condition and the desired result after grinding. โดยทั่วไป, the 120 mesh wheel is used to initially remove the roughness of the initial surface, the 180 mesh wheel is used to further remove most of the roughness, the 240 mesh wheel starts the rotary grinding process, and the 320 mesh wheel is the final fine adjustment and polishing.

grinding step

1. Initial grinding

First, use a 120-grit grinding wheel to gently rub back and forth along the direction of the handle to smooth the surface of the handle. The purpose is to remove surface roughness and scratches.

2. Second grinding

ต่อไป, use a 180-mesh grinding wheel to wipe back and forth the marks made by the previous grinding in the longitudinal and horizontal directions, which can basically remove the marks of the 120-mesh grinding wheel.

3. Third grinding

Use a 240 grit wheel for further sanding, rubbing gently in one direction with the aim of removing any small scratches and blemishes. After this step, you can lightly touch the surface of the handle to see if it has become smooth and even.

4. Final fine-tuning and polishing

For final fine-tuning and buffing, use a 320-grit grinding wheel to lightly scrub the surface to remove last imperfections and roughness. Alternately rub left and right until the surface of your knife handle looks smooth.

【Conclusion】

Shank grinding is a very important step, and the correct selection and use of the grinding wheel mesh can help us get the desired results. It should be noted that patience and care are required in the polishing process, and every step should be done to the best.
