Common problems in the production process of diamond resin grinding wheels

Many quality problems may occur during the production process of diamond resin grinding wheels, as the production of diamond resin grinding wheels belongs to the multidisciplinary classification of composite materials, resulting in complex and complex causes. Today, what I want to explain to you is one aspect of the reason.

The production of diamond resin grinding wheels is an industrial product with strong craftsmanship, and there are many problems in processes such as mixing, forming, hardening, and processing.

(1) Mixing process: The key to mixing is uniformity, and the formed material should achieve: uniform distribution of all components, maintaining looseness, but not significant powder leakage. It is necessary to ensure uniform spreading and excellent forming function.

(2) Forming process: Currently, most of the domestic rotary paving organizations are used, but due to the limitations of the rotary paving organization, there are many production enterprises where employees do not operate properly, the mixture is unevenly distributed, and the position and static balance are out of tolerance.

(3) Hardening process: This is a key production process, and there are two factors that can easily cause quality problems. One is the large temperature difference in the curing oven or firing kiln; The second is the improper method of loading the furnace. The temperature difference between the hardening furnace and kiln is too large, causing the hardening of the diamond resin grinding wheel to deviate from the set hardening standard (hardening curve), resulting in insufficient assurance of the curing (hardening) quality of the grinding wheel.

(4) Processing process (mainly large diameter and high thickness diamond resin grinding wheel): Diamond resin grinding wheel, especially large diameter and high thickness, may require strict scale service of grinding wheels to be processed after hardening to ensure the geometric scale and shape of the grinding wheel are in service.

(5) Produce formulas and process parameters mechanically.

Of course, in addition to the production process issues mentioned above, there are also issues with equipment and tooling.

(1) Equipment issue: The production equipment is an important material condition for the production of grinding wheels. Some enterprises lack equipment, such as a lack of good mixing machines or a small tonnage specification of hydraulic presses; At the same time, equipment protection and maintenance are poor, and product quality is not easily guaranteed.

(2) Tooling issue: Some small-scale diamond resin grinding wheel enterprises have weak tooling management and do not have outstanding storage facilities, resulting in disorderly stacking and stacking at the production site.

Inspection equipment issues:

(1) Raw material inspection, process inspection, and factory inspection are important aspects of effective inspection and control for diamond resin grinding wheel production enterprises. However, there are few production enterprises that achieve standard and standardized management. The primary issues include incomplete guidelines, failure to execute functions, lax management, lack of control of inspection equipment, and poor professional quality of inspection personnel.

(2) Incomplete setup of inspection equipment

The inspection equipment is incomplete, and there are three major pieces of inspection equipment for diamond resin grinding wheels: rotary strength testing machines; Sandblasting hardness machine - resin slicing and grinding on the outside; Static balancer (for diamond grinding wheels, dynamic balancer is also required), and other equipment should include thin grinding wheel end face, radial runout tester, inner diameter gauge, vernier caliper, grinding wheel cutting function testing machine, etc.
