飯島精機 List of Products and Services

We have received many inquiries regarding the manufacturing of laminated motor cores, where customers express a desire to handle everything in-house from adhesive lamination to wire cutting, but find that adhesive lamination requires technical expertise that makes it difficult for them to manage internally, leading them to seek suppliers for laminated materials. The block material made from laminated electrical steel sheets has been used internally for some time, but in response to the aforementioned needs, we developed the "Motor Core Block." We believe that our adhesive technology for laminated cores possesses unique know-how that cannot be replicated by other companies, and we have gained strong trust from major manufacturers, especially regarding the prototyping of laminated cores. The sizes of the Motor Core Blocks can accommodate a wide range, from 50mm x 50mm, 75mm x 75mm, 100mm x 100mm to 300mm x 300mm. The adhesive height for the Motor Core Blocks can be adjusted from 5mm to 80mm, allowing for the production of high adhesive laminated blocks. Additionally, we offer a limited selection of materials, specifically 35A300 (0.35t) and 50A470 (0.5t), which are frequently requested by our customers.

This is a round shim for FA equipment. The material is SUS304, and high-precision wire cutting is performed on the holes and outer circumference where there are tolerances. This round shim was processed by sandwiching multiple stacked blanks with thicker steel material, reducing vibration during processing caused by cutting fluid injection. Additionally, since there were tolerances on both the holes and the outer circumference, the holes were processed in four stages to enhance finishing accuracy. Two starting holes were set on the outer circumference, and cutting was done in four stages by dividing it into two parts. After that, the excess was trimmed, and the part with a negative tolerance at the center was corrected with a file. Our company supports the procurement of various materials, not only general steel and SUS but also from amorphous products to special alloys, and we provide one-stop service from prototype processing of custom shims to mass production. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices.

This is a large round shim for power transmission devices. The material is A1100, and it has a total of 14 holes processed. This round shim was processed by sandwiching multiple stacked blank materials with thicker steel, reducing vibration during processing caused by the injection of cutting fluid. Additionally, all dimensions are within general tolerances, and it was processed with a single cut around the entire circumference. However, since having only one starting hole on the outer circumference can cause the workpiece to move during processing, we have created two or more starting holes for processing. In wire cutting of aluminum products, if the wire breaks during the process, a film may form on the cut surface, making it impossible to resume processing. Therefore, we take measures such as lowering processing conditions to prevent wire breakage. Our company is capable of sourcing a variety of materials, not only common steel and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Moreover, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices.

This is a custom shim (spacer) for power transmission devices. It is made from phosphor bronze (C5191) material, punched out using press processing. The thickness precision requirement for this custom shim is ±0.01mm, and the customer has also requested a flatness of 0.02mm for both the front and back surfaces. In cases like these, it is difficult to guarantee precision with the material alone, so we perform double-sided grinding after press processing. The custom shims we receive requests for often require such high precision as they are precision press products. Additionally, we do not limit ourselves to just phosphor bronze; we also accommodate double-sided grinding for brass, yellow brass (C2680, C2801), and copper (C1100). We handle a wide range of materials, from general iron and SUS to amorphous products and special alloys, providing one-stop solutions from prototype processing to mass production for custom shims.

This is a motor core for vehicles. The material is SECC, and it has been processed using wire cutting. This motor core is a prototype cut piece for confirming the shape. Normally, motor cores are processed using electromagnetic steel sheets such as 20A1500, but this time, there was a request from the customer to quickly touch and verify the shape. Therefore, we have manufactured it using wire cutting with SECC material to ensure a short delivery time. Our company is capable of sourcing a variety of materials, not only standard iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing to mass production of custom motor cores. Additionally, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices. As a result, we also propose cost reduction from the design stage based on past processing data. If you are having trouble with the design and manufacturing of custom motor cores, please feel free to contact our custom shim manufacturing center.

This is a stator core (φ250×0.2mm). The material is 20A1500, and it is a product used for vehicles. This stator core is relatively large at φ250mm, and if processed by wire cutting, it would incur enormous costs in terms of both time and money. Therefore, our company manufactured it by creating a prototype mold and performing punching through press processing. Due to the narrowness and high number of teeth, high precision in the processing and assembly of the press mold components is required. However, at our custom shim manufacturing center, we were able to produce a clean finish with almost no burrs using precision press processing with molds that have good assembly accuracy. Our company is capable of sourcing a variety of materials, not only common iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing to mass production of custom motor cores and stator cores. Additionally, based on the data accumulated in our unique production management system, we offer products to customers at reasonable prices.

• DC Motor

This is a motor core (φ110×0.2mm). The material is 35A440, and it is primarily used as a component for power transmission devices. For this core, we processed it by sandwiching multiple stacked blank materials with thicker iron to reduce vibration during processing caused by the injection of cutting fluid. The processing steps were carried out in the order of "outer circumference rough machining → hole rough machining → outer circumference finishing → hole finishing." Additionally, for motor cores of this shape, having only one start hole on the outer circumference would cause the workpiece to move during processing, so we created two or more start holes for machining. Our company is capable of sourcing a wide range of materials, from general iron and SUS to amorphous products and special alloys, and we provide one-stop support from prototype processing of custom shims to mass production. Furthermore, based on the data accumulated in our unique production management system, we offer products to customers at appropriate prices. Therefore, we also propose cost reduction from the design stage based on past processing data. If you are facing challenges with the design and manufacturing of custom motor cores or precision press parts, please feel free to contact our custom shim manufacturing center.

This is a laminated core for stepping motors. It was manufactured by laminating electromagnetic steel sheets with a thickness of 0.2t using round dowel rivets. Unlike the common thicknesses of 0.35t or 0.5t for laminated core steel sheets, the 0.2t round dowel rivet lamination requires a very high precision press mold. However, our company designs and manufactures the press molds for laminated core production in-house, and we have numerous achievements and know-how regarding the prototype processing of laminated cores, so we can handle the production of laminated cores with such high precision without any issues. We are capable of sourcing a variety of materials, not only general iron and SUS but also from amorphous products to special alloys, and we provide one-stop support from prototype processing of custom shims to mass production.
