Are you performing everything from cutting and grinding to chamfering and deburring with a single NC machine (such as machining)? By dividing the process into two steps—NC machining and deburring/chamfering—you may improve production efficiency. The reason is that deburring and chamfering on an NC machine takes "too much time." At Koyama Seisakusho, we offer deburring and chamfering machines that can contribute to improving work efficiency and production efficiency. ■ Currently accepting test processing ■ * You can check the finish by conducting test processing! * For more details, please refer to the catalog or feel free to contact us.

We will introduce a machining case using the Koyama chamfering machine. Sprockets, used for transmitting large amounts of power, are found in parts for motorcycles and construction machinery. Since gears are used for various applications, there is a wide variety of products ranging from standard to special items. The teeth of sprockets are narrow, making the methods for chamfering and deburring challenging. Koyama's irregular shape copying machining can accommodate the tooth shapes of such sprockets. We can perform simultaneous machining on both sides of a Φ110 sprocket in just 20 seconds. [Case Study] ■ Sprocket ■ Φ110 outer diameter simultaneous machining on both sides ■ Machining time: 20 seconds ■ 2-axis machining For more details, please refer to our catalog or feel free to contact us.
