The "353RNRQ" is a balancing machine specifically designed for propeller shafts. Propeller shafts are composed of multiple parts and operate at high rotational speeds, which can cause deflection; therefore, it is necessary to measure the balancing speed close to the actual vibration conditions of the machine. It is also possible to equip a correction device based on customer requests. 【Features】 ■ Specifically for propeller shafts ■ Correction device can be equipped based on customer requests ■ Equipped with the microprocessor measurement unit "MMi-902P" *For more details, please refer to the external link or feel free to contact us.

The "821/823LAMC" is a final balancing machine developed to flexibly accommodate the balancing of crankshafts within the production line. It can measure, correct, and check all automatically with a small installation footprint, allowing for free design of the production line layout. In the correction station, new technology has significantly reduced the clamping force, eliminating the need for a hydraulic system. 【Features】 <821LAMC> ■ Adopts friction drive ■ Mainly used in production lines for inline 3-cylinder and 4-cylinder crankshafts <823LAMC> ■ Adopts hook drive ■ Suitable for production lines of V6 cylinder crankshafts *For more details, please refer to the PDF document or feel free to contact us.

The "823LAMM" is a mass centering machine that achieves both the maintenance of specified weight with counterweights and balancing. By measuring the mass center of the crankshaft and processing around the mass center, this balance is realized. It is compatible with inline 3-cylinder and 4-cylinder crankshafts, and switching between them can be done easily. Additionally, we also introduce the final balancing machine "821/823LAMC." 【Features】 ■ Full cover on the processing section reduces the scattering of chips during cutting ■ Use of a main loader allows for flexible arrangement of each component ■ Machining of reference surfaces can be added as an option *For more details, please download the PDF or contact us.

The "010 LADT" is a fully automatic balancing machine designed specifically for small turbochargers for automobiles. It consists of an inbound/outbound section, an unbalance measurement section, and a milling correction section, with the workpieces being automatically transported to each station by a two-arm in-machine loader. Additionally, we also introduce the turbocharger-specific "010/020 MMBT" and the high-speed turbocharger core assembly "110 MMST." 【Structure】 ■ Inbound/Outbound ■ Marking Station ■ Measurement Station ■ Correction Station *For more details, please download the PDF or contact us.

The balancing machine is used to reduce the vibrations of rotating bodies and performs balance measurement and correction for all existing rotating bodies. By achieving balance, it offers benefits such as improved product performance and extended lifespan. Additionally, a precisely balanced rotor can achieve stress-free high-speed rotation, making it possible to reduce environmental impact. Vertical balancing machines are primarily suitable for disc-shaped rotors that do not have an axis and are more efficient to work with in a vertical position. They are designed with a focus on safety and efficiency, and can accommodate both operator work and inline automatic operation. They are provided according to customer specifications through a selection flowchart. 【Features】 ■ Balance measurement is possible with a variety of functions. ■ It is possible to verify the inner diameter tolerances on the drawing and select a fixing method that corresponds to the achievable unbalance amount. ■ Measurement results and setting data for each rotor can be extracted to a USB memory stick for verification on a computer. *Custom orders will be made according to your requested specifications, so please feel free to consult with us. *For more details, please download the catalog or feel free to contact us.

The balancing machine is used to reduce vibrations of rotating bodies and performs balance measurement and correction for all existing rotating bodies. By achieving balance, there are benefits such as improved product performance and increased longevity. Additionally, a precisely balanced rotor can achieve stress-free high-speed rotation, thereby reducing environmental impact. In the horizontal balancing machine, rotors are measured individually, with a hard type for large rotors (approximately 1kg and above) and a soft type for small, high-speed rotating or assembly rotors. You can select based on a flowchart tailored to your application. **Features of the Hard Type:** - Measurement is possible simply by inputting the dimensions of the rotor with permanent scale calibration. No adjustment work is required for each workpiece. - Flexible expansion is possible, covering a wide range of weights by combining two different types. **Features of the Soft Type:** - No special foundation is necessary. It can be installed on floors two levels or higher. - Measurements are conducted at speeds higher than the resonance frequency, allowing for a higher upper limit of rotational speed, and angle errors do not occur due to rotor-dependent calibration. *For more details, please download the catalog or feel free to contact us.*
