●Updated the precious metal information. [February 1, 2018]

Compared to extruded and drawn materials, there is less variation in outer diameter and reduced bending of the material! We have a large inventory and can accommodate short delivery times!

"Centerless grinding" is a processing method for machining cylindrical materials that does not require center support, allowing for the processing of long materials, pipes, and machined products without selecting specific processing machines. It excels in outer diameter precision, roundness, and straightness, resulting in high-precision materials. We possess a variety of inspection equipment, including bending inspection devices and micrometers, so customer-side material inspection is unnecessary. Additionally, to deliver high precision to our customers, we offer four types of packaging methods, including support packaging. *We have a rich inventory, including A7075B-T6511 and A6061B-T6 available!* 【Features】 ■ Improved yield ■ Increased production efficiency ■ Can be handled with only sampling inspections ■ Supports shortened delivery times *For more details, please refer to our catalog or feel free to contact us.*

Case study of aluminum centerless adoption by an automotive parts manufacturer.

We would like to introduce a case study of an automotive parts manufacturer that has adopted our unique technology, "Centerless Grinding." At Company T, there was variability within the outer diameter dimension tolerances, and they were struggling with material layer separation work before processing. However, since adopting "Aluminum Centerless," they no longer need to perform material layer separation work for thicker and thinner materials, and they are now able to adequately handle inspections through sampling. As a result, work efficiency has significantly improved, and the yield of the processing has remarkably enhanced.

Case study of aluminum centerless adoption by a medical manufacturer.

We will introduce a case study of a medical manufacturer that adopted our unique technology, "Centerless Grinding." Company M was forced to conduct 100% inspection due to material wobbling and lack of roundness, but the adoption of "Aluminum Centerless" significantly improved the processing yield. Additionally, being able to place a consistent order from material procurement to centerless processing is also an advantage. 【Overview】 ■ Medical Manufacturer ■ Company M Dental Medical Devices ■ <Target Parts> A6061B-T6 φ9–11 *For more details, please refer to the PDF document or feel free to contact us.

Case study of aluminum centerless adoption by an industrial machinery manufacturer.

We would like to introduce a case study of an industrial machinery manufacturer that has adopted our unique technology, "centerless grinding." At Company P, even when outsourcing centerless processing to another vendor, aluminum materials were often avoided due to the grinding wheel becoming clogged. However, Hashinaga Metal specializes in aluminum, making it easier to request services, and we received high praise for the finishing quality in terms of outer diameter, straightness, and roundness. Additionally, we have included a case study of machine parts, pins, and shafts from industrial machinery manufacturer Company S.

Is the aluminum material you are currently using really ◎? It is ideal for moving spindle CNC lathes, and its effectiveness is tremendous for parts with strict requirements for roundness and cylindricity.

Centerless grinding is a processing method for machining cylindrical materials. It is called "centerless" because grinding is performed by passing the material between two rotating grinding wheels without fixing the workpiece at the center. It is characterized by superior dimensional accuracy, surface roughness, and roundness compared to drawn materials. 【Application Example】 A2017B-T3: φ2.1～φ3.0×2500mm (2000mm) *After centerless processing Outer Diameter Tolerance: +0 -0.004 Roundness: 2μm Application: Two-wheeled vehicle carburetor parts

No need for material inspection before use or for stratification work with thicker or thinner layers! Significantly improve processing yield!

【Feedback from Medical Manufacturer M】 ■Issues: When processing the drawn material as is, the material would wobble, causing misalignment in the product's axis, which was problematic. ■Suggestion: Use centerless material. ■The need for material inspection before use and for sorting into thicker and thinner layers has been eliminated, significantly improving processing yield.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

● The production time for casting prototypes can be shortened! Since model making is not required, the production time for prototypes, which previously took about a month, can be significantly reduced. ● Model costs can be reduced! By directly creating sand molds from 3D data, there is no need for model production costs. If changes to the model are necessary, they can be addressed by modifying the 3D data. ● Similar products with different shapes and dimensions can be prototyped simultaneously! Different products, such as similar shapes or variations in dimensions, can be created in a single molding process. This allows for the verification of multiple types in a short period.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding repair methods can alter the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

Japan is among the top 10 countries in the world with frequent earthquakes. The 2020 White Paper on Land, Infrastructure, Transport and Tourism has also reported an increase in the probability of significant earthquakes occurring. For the Nankai Trough earthquake, the probability of an earthquake with a magnitude of 8 to 9 occurring within the next 30 years is estimated to be 70 to 80%. At Hotron, we recommend the introduction of seismic devices for earthquake measures in buildings and equipment. The seismic device 'HK-2' is a product that automatically performs various controls that have been pre-set when it detects strong shaking equivalent to a seismic intensity of 5 lower or higher. For example, it can automatically execute actions such as: "Open automatic doors and gates to secure evacuation routes and access for emergency vehicles" "Transmit signals to the control room and stop facility equipment" "Unlock the keys to locked lockers" "Automatically play voice guidance" ◎ For more details, please download the materials or contact us.
