Save 0.5 Yuan per Kitchen Knife with Higher Safety & Efficiency! This Yangjiang Enterprise Breaks Bottlenecks in Traditional Knife & Scissors Manufacturing
2026-04-29
At present, Yangdong District is forging ahead with industrial transformation and upgrading, and actively building a new ecosystem for smart manufacturing. As a high-tech enterprise in Yangdong, Guanghai Machinery focuses on intelligent equipment such as CNC double-sided knife grinders and flat belt sanders by leveraging digital technologies, providing solid technical and equipment support for the transformation and upgrading of the traditional knife and scissors industry.
Recently, reporters visited the company’s production and testing workshop and witnessed operators working at CNC double-sided knife grinders. After grinding parameters are entered, the system automatically drives fixtures to hold the cutlery to be processed, and the grinding wheels on both sides start synchronous grinding according to preset procedures in an efficient and streamlined workflow.
In the past with traditional hydraulic machines, workers had to closely monitor pressure gauges and make manual adjustments, resulting in poor stability and difficult operation. Today, CNC technology solidifies complex craft parameters into digital programs, enabling precise replication of key dimensions for every batch of products and achieving fundamental control over defective rates.

The upgrade from traditional hydraulic knife grinders to CNC models has greatly improved product stability and standardization.
At the flat belt sander testing station, its fully enclosed integrated design stands out. Driven by the conveyor belt, cutlery undergoes rough grinding and fine polishing in sequence, delivering high efficiency and safety. These complicated procedures once required multiple devices and joint work by several workers.
Huang Dahai introduced that traditional open polishing equipment has long been a high-risk source of workplace injuries in the knife and scissors industry, with hidden dangers including flying debris, exposed high-speed rotating parts and intensive manual operation. Their integrated design ensures operational safety through physical isolation and process optimization.

The flat belt sander eliminates workplace accidents caused by tooling in automatic polishing, greatly boosts working efficiency, and resolves common defects such as rough patterns left by rubber wheels and product rusting. The production cost of one kitchen knife can be reduced by 0.4 to 0.5 yuan compared with traditional single-sided grinding equipment.
The successful application and promotion of Guanghai Machinery’s CNC equipment series provide robust hardware support for local hardware, knife and scissors manufacturers. It helps the traditional industry shift from experience-driven production to intelligent manufacturing, and strongly underpins Yangdong District’s efforts to build a resilient, competitive modern industrial system for knives and scissors.
