Making of Ko-ken products  TEST AND LABORATORY  TESTLABOR  TEST AU LABORATOIRE Ko-ken uses a variety of test equipment. Strength is measured by the Static Load Test Machine that can measure torque load up to 5,000Nm. Durability is measured by the Cyclic Test Machine and corrosion resistance testing is done by the Salt Spray Test Machine. The test results are used to improve our standard products and assist with new product design and development. Wir verfügen über die verschiedensten Testgeräte: -Die Festigkeitseigenschaften der Werkzeuge werden mit einer statischen...

 FORGING  SCHMIEDEN  FORGEAGE  TURNING  DREHEN  TOURNASAGE The Forming machines are used for the forging process. These machines can produce mass quantities of sockets and parts with high accuracy that ordinary drop forging machines can not achieve. However, ordinary forging machines are also used for small production runs. The forged steel is turned into required shapes and dimensions. The MC (Machining Center) operates with extraordinary speed and precision. The article number, size, logo, production number, and MADE IN JAPAN are marked on the products after the turning process has...

Making of Ko-ken products  HEAT TREATMENT  HÄRTEN  DURETE  INSPECTION  MESSEN UND PRÜFEN  CONTRÔLE To make the tools stronger and more durable, proper heat treatment is critically important. The temperature and the time of the heat treatment are strictly regulated by a very accurate control device. Our products are periodically checked at each production process by inspection devices. Highly accurate 3-D measuring instruments are used to inspect and confirm dimensions. Um die optimale Stabilität und Festigkeit der Werkzeuge zu erreichen ist der Härtungsprozess der Werkzeuge von...

Technical Features of Ko-ken Tools Technische Besonderheiten der Ko-ken Werkzeugen Particularités techniques des outils Ko-ken FLAT DRIVE® Das Flat Drive Design sorgt für die optimale Kraftübertragung zwischen den Flächen des Steckschlüssels und der Schraube. Dies erlaubt eine Übertragung von höheren Drehmomenten. Das Flat Drive System findet ebenfalls bei allen Antriebsvierkanten sowie bei 6-kant und 12-kant Profilen Verwendung. Flat Drive is designed to guarantee a flat surface contact between the socket and the bolt/nut. The Flat contact reduces wear and allows to transmit a higher...

Technical Features of Ko-ken Tools Technische Besonderheiten der Ko-ken Werkzeugen Particularités techniques des outils Ko-ken SOCKETS STECKSCHLÜSSEL DOUILLES SURFACE DRIVE Surface drive sockets are designed to retain contact with the flat sides of the nut in order to transmit higher torque and reduce nut wear. These sockets are ideal for using on polished nuts, aluminum nuts and nuts with worn out points. Das Profil unserer Surface-Drive Steckschlüssel greift die Schraube an deren Flächen. Dies sichert eine höhere Kraftübertragung und verhindert ein Durchrutschen des Steckschlüssels. Diese...

Technical Features of Ko-ken Tools Technische Besonderheiten der Ko-ken Werkzeugen Particularités techniques des outils Ko-ken S.O.D.H-System® Two dogs are located in the ratchet body so that the dogs and springs are held securely in place, allowing the reversing lever and dog to switch smoothly. The torque load on the gear is transmitted vertically to the dog, and in turn, down the ratchet handle. This mechanism locks gears tightly in place while torque is being applied, thus avoiding any gear slippage. Die zwei Sperrklinken sind fest im Knarrenkörper verankert, die Federn sind dadurch...
