The "KN-421" is a mass-production type of combined grinding machine for simultaneous internal and external grinding, developed and manufactured by consolidating pioneering technology along with the experience and accumulated know-how gained from thousands of products used in the industry. Traditionally, internal grinding and external grinding were processed on separate grinding machines, but now, simultaneous grinding in a single machine has achieved high precision, high efficiency, and labor-saving in the mass production process. 【Features】 ■ High rigidity structure enables high precision and high efficiency by performing combined grinding of internal and external surfaces with one chucking. ■ Since both internal and external grinding are performed by the grinding wheel side, the loading and unloading positions of the workpiece remain constant. ■ The workpiece chucking method is of the shoe magnet type. ■ Capable of mass production of workpieces. *For more details, please download the PDF or contact us.

The "KN-113B" is an internal grinding machine designed for the automation of mass-produced workpieces. With its unique powerful magnetic chuck, it supports the workpiece with a shoe and rotates it based on the right angle surface that has been ground on the outer diameter and end face. It is particularly suitable for internal grinding of components such as pairing, bushes, and collars, and is an ideal processing method for ensuring the concentricity of the outer diameter relative to the inner diameter. 【Features】 ■ The loading method can be selected from options such as T-type loaders, carrier methods according to the shape of the workpiece, single-arm methods, and flow-type methods, allowing for a reduction in idle time. ■ Direct dimensional gauges are also available, similar to the 113A type. *For more details, please download the PDF or contact us.

The "KN-314" is a special dedicated external grinding machine designed for grinding the outer diameter of tripoint rollers based on high-precision grinding technology developed over many years with external diameter grinders. In addition to grinding true circles and spherical surfaces, it achieves elliptical processing through our unique NC program grinding, accommodating a variety of external surface grinding needs. 【Features】 ■ Shockless high-speed rotation and high-speed vertical drive reduce transport time ■ Ensures automatic transport of workpieces by connecting with IN and OUT roller chutes ■ Equipped with our unique 120° divided indexing mechanism and positioning devices for each axis (ensuring accurate positioning and grinding of the three axes of the workpiece) ■ Adoption of high-rigidity bearings through the combination of cylindrical rollers and angular bearings, etc. *For more details, please download the PDF or contact us.

The "KN-532/533" is a fully automatic super finishing machine for ball bearings that can form an automatic line by connecting with pre-processing and post-processing machines and chutes. Thanks to the lightweight design of the swinging part, it has a structure that minimizes vibration even when the grinding wheel swings at high speed. Additionally, the machine's overall width is 1 meter, making it space-saving compared to conventional machines. 【Features】 - By using an indexing drive for the carrier drive, it achieves high-speed and reliable loading. - Mist lubrication allows for high-speed rotation of the spindle. - Setup changes and oiling can be performed from the front of the machine. - The number of processing axes is 2 axes with 1 carrier and 4 stations. *For more details, please download the PDF or contact us.

The "KN-312A/B" is an external grinding machine that enables precise and accurate feed cutting due to the adoption of large ball screws directly connected to AC servo motors for both the feed cutting mechanism and the dressing feed. It significantly reduces maintenance time. Additionally, the cutting position and cutting speed are displayed on the CRT, allowing anyone to operate it easily. 【Features】 - Minimum cutting amount and cutting speed can be set in units of 0.5 microns - Spindle cutting method: Achieves balanced and stable machining accuracy - Hydrostatic grinding wheel spindle: Minimizes spindle runout and extends bearing life indefinitely - A hydraulic tank unit with an accumulator and oil cooler is included as standard - An automatic balancing system can be installed as an option, eliminating tedious balancing tasks and unnecessary time *For more details, please download the PDF or contact us.
