浜井産業 Product Lineup

We would like to introduce the "Hob Machine" handled by Hamai Sangyo Co., Ltd. For high-precision gear processing, gear grinding is usually performed after gear cutting. However, our hob machine can finish small module gears, which are difficult to grind, to a precision comparable to that of grinding. It is active in a wide range of fields related to small gear processing, including wristwatches, power tools, fishing gear, stepping motors, and electrode processing for gear molds. We boast a shipping record of approximately 7,000 units to date. 【Product Lineup】 ■ N80: Pursuing high precision and high performance ■ N60: High production performance ■ N40: Compact and quality-focused ■ GN150: Pursuing high precision and high performance *For more details, please refer to the PDF document or feel free to contact us.

• Flat/Shaped/Vertical Cutting Machine

The "DS Series" is a double-sided milling machine that has a proven track record and reliability as a long-lasting and stable mass production machine. It features a heavy base casting and sliding surfaces that utilize a smooth sliding surface. The powerful spindle driven by gears enables heavy cutting and high precision. It is capable of machining difficult materials, including die steel and hardened steel. 【Features】 ■ The sliding surfaces of each axis are made of high-rigidity rectangular slides ■ Achieves stable precision with a long lifespan ■ Capable of high-precision right-angle machining ■ The gantry clamp can be easily rotated ■ NC device uses FANUC *For more details, please refer to the PDF materials or feel free to contact us.

• Milling machine

The "HLG-9" is a precision double-sided grinding machine that allows for easy processing of materials such as stainless steel, resin, and ceramics without clamping. By adjusting the load control on both sides, it grinds the material to achieve a flat surface, addressing issues of flatness (warping and waviness). Regardless of where the individual workpiece thickness is measured, it will finish to the same thickness. Additionally, we offer several fixed-size measuring devices that correspond to thickness tolerance. 【Features】 ■ Reliable parallelism and flatness ■ Stable dimensional accuracy ■ Strong performance with non-ferrous metals ■ Amazing processing speed ■ Choice of reference plates *For more details, please refer to the PDF document or feel free to contact us.

• Grinding Machine

We handle "Precision Single-Sided Lapping and Polishing Discs." The single-sided lapping disc, developed using the technology of double-sided lapping discs, adopts radial fluid bearings in the thrust direction as well. This has brought the rotation of the base plate even closer to the ideal. Not only does it reduce vibration, but it also improves the rotation stability and load capacity of the base plate, achieving high stability in single-ring processing. It can handle a wide range of processing conditions, from high-hardness materials to those with strong cleavability. 【Features】 ■ Fluid bearings are standard equipment on all models (HAMAI original) ■ Easy maintenance of the flatness of the base plate ■ High-precision processing of various materials through a rich selection of options *For more details, please refer to the PDF document or feel free to contact us.

• Wafer processing/polishing equipment

The N80 is a CNC horizontal hobber designed to accommodate long workpieces, with a maximum mounting length of 350mm. By adopting a hydraulic system for the bob arbor and rest section, hob replacement is made easy. The tailstock is servo-driven, making setup even easier. It enables high-speed machining through dry processing and allows for heat-treated material processing using both dry and wet methods. 【Features】 ■ Maximum mounting length of 350mm to accommodate long workpieces ■ Hydraulic system for the bob arbor and rest section facilitates easy hob replacement ■ Servo-driven tailstock makes setup even easier ■ High-speed machining possible with dry processing ■ Heat-treated material processing possible with both dry and wet methods *For more details, please refer to the PDF document or feel free to contact us.
