IZUMI KINZOKU's profile grinders enjoy a great deal of popularity for its reliability in extensive grinding applications and in particular among bearing industry and automobile industry. The reputed acceptance and proven performance of our grinders are substantiated by our expertise and experience developed over the past 30 years and successful shipment of 1000 units to date.
Improved dynamic rigidity of the work head feed mechanism, stabilized double arm type loading and unlording mechanism, infeed grinding and dress compensation controlled by an independent AC servo motor eliminate inferior accurcy due to thermal influence and vibration and provide excellent grinding performance with high accuracy.

CNC FEED MECHANISM
On both grinding and dressing feed, large size precision Ball Screws directly connected to AC servo motors bring precise and steady infeed travel greatly cutting down maintenance time. CRT screen displays feed position and speed enabling simple and easy operation for every person.
Feed amount and speed can be set at minimum unit of 0.5 microns to resize an optimum grinding condition easily. |

WORK HEAD INFEED SYSTEM
The Work head slide performs infeed motion while the Wheel head which is usually the largest vibration source is rigidly mounted onto the machine bed. This arrangement achieves stabilized grinding accuracy. |

HYDROSTATIC SPINDLE BEARING
Wheel spindle is supported by IZK's unique Hydrostatic bearing system which contribute to a minimum spindle runout and semi-permanent bearing life. A hydrostatic pump/tank unit with accumulator and oil coolant is provided in standard accessories. |

AUTOMATIC WHEEL BALANCING SYSTEM
An excellent and sensitive Auto-balance system is provided as an option to eliminate troublesome balancing and time loss. |

LOADING DEVICE
The most popular loading and unloading device is double arm type which is usually combined with shoe-magnet type work support. It consists of a loading arm and unloading arm driven by a simple rack-pinion mechanism giving quick, steady work movement and less maintenance. According to type and size of work pieces, some other types of loading are also adopted. |

WORK SUPPORT
For grinding ring type work pieces, We recommend shoe-magnet system. (KN-312B) In this, a strong magnet-chuck holds and rotates the work piece steadily while a pair of shoes support its outside black skin to achieve complete ground roundness and squareness. A built-in type demagnetizer is also installed. For some work pieces other than ring type. IZK designs an optimum support system such as diaphragm chuck combined with a proper loading device.(KN-312A) |
