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.

<Features of Aluminum Centerless Grinding Materials> 1) High precision throughout the entire length of long materials (can also accommodate JISB0401 h5 class) 2) High bending accuracy; exceptional correction technology reduces material bending (4μm/100mm) 3) Ideal for spindle-moving CNC lathes (Peeterman), contributing to improved part accuracy, yield, and process reduction. <Advantages of Adoption> 1) Reduced variation in outer diameter dimensions; eliminates the need for stratified work on materials before processing (no need to separate into tolerance plus and minus), allowing for direct processing. 2) Improved yield; due to good material accuracy, the yield improves for parts that require higher precision. 3) Reduction in inspection processes; stable accuracy significantly enhances process capability, allowing for sampling inspection instead of 100% inspection.

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

Centerless grinding is a processing method used for machining cylindrical materials. It is called "centerless" because grinding is performed by passing the workpiece between two rotating grinding wheels without fixing it at the center. It is characterized by superior dimensional accuracy, surface roughness, and roundness compared to drawn materials. 【Adoption Example】 A6061B-T8: φ6.5～φ14×2500mm Outer Diameter Tolerance: +0 -0.006 Bending Tolerance: 4μm/100mm or less Surface Roughness: 3.2S or less Application: Automotive transmission parts

Aluminum centerless grinding (polishing) materials that meet customer needs.

The aluminum centerless grinding (polishing) materials from Hashinaga Metal Co., Ltd. feature characteristics that meet customer needs for centerless materials, such as "excellent dimensional accuracy over the entire length of long materials," "superior bending precision," "materials with no variation between lots," "excellent surface finish," and "stable quality and supply system." Issues with aluminum centerless grinding (polishing) include "prone to spiral scratches," "residual effects of material bending," "low mass production capability due to slow grinding (polishing) speed," "frequent clogging of grinding (polishing) magnets," and "susceptibility to thermal effects, making it difficult to achieve dimensional accuracy," but we have resolved all of these issues.

This is a processing method devised for machining cylindrical materials.

Centerless grinding (polishing) is a processing method devised for machining cylindrical materials. It is an excellent method that achieves high rigidity, high efficiency, and high precision processing without the need for center support, as the material is extensively supported by two rotating magnets and a fixed support blade in between. At Hashinaga Metal Co., Ltd., we specialize in processing long materials through sulfide grinding (polishing). Regarding bending, there are two-dimensional and three-dimensional bends, and general rod materials typically exhibit a combination of both two-dimensional and three-dimensional bends. For more details, please contact us or refer to our catalog.

We provide a combination of various materials and plating functions.

Kyonaga Metal's plated materials are offered by combining various materials with plating functions. For many years, they have been adopted in the automotive and electronic component industries. Depending on the quantity, material, and size, it is also possible to slit the product width after wide plating. Partial or single-sided plating can be accommodated using jigs and masking methods. We can also handle composite processing such as primary plating → pressing → secondary plating. For more details, please contact us or refer to our catalog.

It is a long material in the form of a rod or tube processed by drawing using a non-standard die.

Special-shaped extruded materials refer to long materials such as bars (bars/rods) or pipes that have been processed through drawing (pulling) using special-shaped dies. Compared to extrusion processing, they are characterized by high dimensional accuracy. Various cross-sectional shapes can be achieved depending on the shape of the die (mold). The materials used include aluminum, copper alloys, and various non-ferrous metal materials. Typically, products are finished from round bars through machining, but with special-shaped extruded materials, they are pre-processed into shapes closer to the final product, allowing for various cost advantages.
