Steel calibrated hexagons are high-precision metal products widely used in various industries. Their distinguishing feature is extremely precise dimensions and geometric correctness of the cross-section. But why is precision so important? And how is it achieved in the manufacturing process? Let’s delve deeper.
The precision of dimensions of calibrated hexagons is the result of a complex technological process and the use of modern equipment. The high precision of these products ensures their wide application in various industries. By choosing calibrated hexagons, you can be assured of the quality and reliability of the finished products.
Why is precision of dimensions so important?
- Creation of precise parts. In machine engineering, instrumentation, and other sectors requiring high precision, calibrated hexagons are the basis for manufacturing parts. Even slight deviations from the specified dimensions can lead to the emergence of play and gaps, negatively affecting the operation of mechanisms.
- Increased strength of structures. Precise geometry promotes even load distribution across the entire cross-section of the part, enhancing its strength and reliability.
- Reduction of material waste. Using calibrated hexagons significantly reduces production waste, as there is no need for additional machining to achieve the required dimensions.
- Shortening production time. Precise dimensions allow for a reduction in the time required for assembly and setup of equipment, ultimately leading to lower production costs.
- Quality assurance of the finished product. The use of calibrated hexagons is one of the factors ensuring the high quality and durability of the finished product.
How is dimensional precision achieved in the manufacturing process?
The manufacturing process of calibrated hexagons includes several stages, each aimed at achieving maximum precision:
- Selection of raw material. High-quality alloyed or carbon steel with a homogeneous structure is used for the production of calibrated hexagons.
- Hot rolling. In the first stage, the workpiece undergoes hot rolling, giving it a rough hexagonal shape.
- Cold rolling. The next stage is cold rolling, which allows for more precise dimensions and improved surface quality.
- Calibration. The final stage is calibration. The rolled material is passed through special gauges that provide it with its final shape and precise dimensions.
What calibration methods are used?
- Mechanical calibration. Carried out using calibrating rolls that press the workpiece to the specified profile.
- Hydraulic calibration. High liquid pressure is used to deform the workpiece.
- Electrochemical calibration. Based on the electrochemical dissolution of metal from the anode (the workpiece) and its deposition on the cathode (the gauge).
Quality Control
At every stage of production, thorough quality control is conducted. Modern measuring instruments are used to determine the dimensions and geometric parameters of the finished products with high precision.
Factors Affecting the Dimensional Accuracy of Steel Calibrated Hexagons:
- The quality of raw materials is a fundamental factor determining the accuracy of the final product. It is critically important to use steel with an exact chemical composition that meets established standards. The material should have a homogeneous structure throughout, free of internal defects such as voids, cracks, or non-metallic inclusions.
- The accuracy and technical condition of the production equipment directly influence the quality of the final product. All machines and calibration equipment used must be in optimal technical condition, undergo regular maintenance and adjustments. Particular attention is paid to the accuracy of calibration and the adjustment of measuring instruments, which must provide reliable readings.
- Thermal treatment is a critical stage in the production of calibrated hexagons, requiring strict adherence to technological parameters. It is necessary to maintain the specified heating temperature and holding time accurately, ensuring uniform heating of the product throughout its volume. Special attention is given to the cooling process, which must occur evenly to prevent deformation and internal stresses.
