Process Equipment
Annealing Furnace
Our annealing furnace uses fully automated computer programs to monitor furnace temperature with periodic checks and adjustments. The purpose of annealing heat treatment is to restore the properties of the metal reduced by cold working, increasing its softness, ductility, and toughness.It also releases internal residual stress and generates specific microstructures, improving subsequent machinability.
We offer annealing heat treatment services for various aluminum alloy grades, customized to the customer's subsequent processing requirements.
The annealing process for work-hardened aluminum alloy products goes through three stages:
Recovery, recrystallization, and grain growth.
▲Work Hardening: Aluminum alloy products undergo cold working, and as the amount of deformation increases, changes occur in the crystal structure of the material. Increased dislocation density due to deformed and elongated grains enhances the strength and hardness of the product, while its ductility decreases and its plasticity reduces. This phenomenon is known as work hardening or strain hardening.。
▲Stress Relief: To meet further processing requirements, greater external forces must be applied, increasing the risk of product failure.

Hone
Honing Machine
Honing is a precision technique for aluminum alloy tubing pieces, mainly to improve the smoothness of holes after drilling and internal circular grinding. The honing tool consists of a set of abrasive strips made of alumina or silicon carbide, commonly called "oil stones." These oil stones are embedded in a rotating spindle, and through specific speed and pressure, they create parallel intersecting patterns on the surface of the hole. The honing process can be controlled by using different types and sizes of abrasives, adjusting pressure, and speed.
Honing aims to improve machining precision, including size accuracy, roundness, cylindricity, and surface roughness. It ensures stable machining precision and produces a unique cross-hatched pattern on the product surface, enhancing lubrication.
Compared to internal diameter grinding, honing uses lower rotational speeds and smaller cutting amounts, avoiding harm and internal stresses on the product surface. Honing offers high precision, stability, shorter processing time, and longer tool life.

Grinds, polishes, or trims the product surface. It generally employs grinding wheels or sandstone disks for cutting or grinding, achieving desired shape, dimensions, and surface precision.
The machining action of a grinding machine is known as grinding. It uses grinding tools to remove excess material from the workpiece to achieve the desired shape, dimensions, and machined surface. The sharpening of cutting tools and the precise manufacturing of mechanical parts all rely on grinding work. Grinding is also a part of precision machining.

Grind
Centerless Grinding Machine
Centerless grinding is a type of cylindrical grinding, used to grind cylindrical products. This machine is special in that products aren't fixed in the center but are processed by the rotation and advancement of the grinding wheel. One advantage of centerless grinding is high efficiency and precision, suitable for mass production and automated lines.
Anvil specializes in manufacturing aluminum alloy tubular (hollow) products. Due to the thinner tube walls, considerable skill and conditions are required to maintain dimensions and "improve surface roughness" during grinding. Our centerless grinding services focus on technician operation and the use of high-quality grinding wheel consumables imported from Japan, providing reliable centerless grinding services for aluminum alloy tubing pieces based on your process needs.

Polish
Polishing Machine
Anvil Industries has internal and external tube polishers, offering professional aluminum alloy tubing polishing services to ensure high-quality surface and corrosion resistance. Before undergoing hard anodizing, products must be checked for defects or scratches. If scratches exist and the product undergoes hard anodizing, it will make the marks more prominent and increase the risk of fracture.
To reduce scratches and improve surface roughness, we offer an additional mirror-like polishing process for aluminum alloy tubing pieces after grinding and before hard anodizing. This not only enhances surface roughness but also makes it easier to spot any surface defects, ensuring the quality of anodized tubing pieces. Tubing pieces that have undergone anodizing cannot be reworked; hence, grinding and polishing is an important step before coloration.

Hard
Rockwell Hardness Tester
Anvil uses Rockwell hardness testers imported from Japan, which are applied to test all metal materials and are one of the most broadly used hardness standards. They can test various scales such as HRC, HRB, and HRA and are widely used for hardness testing on various metal components, molds, and heat treatments. These testers can also evaluate material strength, incoming material inspection, and metal hardening capabilities.
Rough

Metallography Testing Procedure (For Aluminum Alloys)
1.Cutting
▲Select the sampling location and inspection surface, taking into account the characteristics and processing methods of the sample, and the selected area must be representative.
2.Mounting
▲If the sample size is too small or the shape is irregular, it needs to be mounted or held with fixtures.
3.Coarse Grinding -> Fine Grinding
▲The purpose of coarse grinding is to flatten the sample and shape it appropriately.
▲The purpose of fine grinding is to eliminate the deeper scratches left by coarse grinding, preparing for polishing.
4.Polishing -> Etching
▲The aim of polishing is to remove fine grinding marks or scratches, resulting in a bright, scratch-free mirror surface.
▲To observe the sample's structure under a microscope, metallographic etching is required.
5.Metalloscopy
▲Observe the "grain size" of the material; grain size has a direct correlation with the material's mechanical properties. Quantitative analysis of grain size can provide an accurate evaluation basis. The number of grains per unit area in metallography is related to the grain size, which has a decisive impact on the metal's tensile strength, material hardness, and ductility.
