Tempered and Polished Steel Rods
High Precision: Ensures consistent and accurate tolerances for superior quality and performance.
Smooth Surface: Provides a smooth and glossy surface finish, enhancing both the product's appearance and functionality.
Substantial Material Savings: With tight tolerances and a polished surface, material waste is minimized. Compared to traditional lathe machining, which consumes more raw materials, this process offers significant savings in both materials and time—particularly valuable when dealing with large quantities of material, leading to notable reductions in overall material costs.
Reduced Processing Time and Equipment Costs: The high precision and excellent surface quality enable direct use in secondary operations such as spraying, sanding, bending, and drilling. This eliminates the need for extensive machining time and reduces the costs associated with additional processing machinery, further optimizing production efficiency and cost savings.
Products Introduction
Tempered and polished steel rod is a metal disk or bar after spheroidal annealing, drawing, straightening, chamfering, cutting, tempering, polishing and a series of processing technology made of precision, straightness, roundness, strength and so on to meet the corresponding requirements of the bar, is the production of high-precision shafts, rods, turned parts, standard parts and other mechanical transmission components required for the important materials.
Generally according to the end use and the production of parts on the precision grinding rod size accuracy, surface quality, straightness, mechanical properties of the material and other requirements to determine the required metal material and processing technology.
Features
1. High precision: ensure accurate and uniform tolerances.
2. Smooth surface: the surface is smooth and bright.
3. Material substantial savings: small tolerances, bright surface, so that the loss of raw materials is minimal, relative to the use of traditional lathe machining cutting materials consumed, the savings in materials and time is very considerable, especially when the amount of material, material cost savings is more significant.
4. Processing time and processing machinery savings: due to accurate precision, good surface condition, can be used directly, such as spraying, sanding, bending, drilling, eliminating the need for a large number of machining time and save the cost of configuring processing machinery.
Classifications
According to the material, the tempered and polished bar can be divided into carbon steel and stainless steel, copper and related alloys, pure titanium and titanium alloy, other metals and alloys and so on.
