三井精機工業 Product Lineup

The "J350G" is a jig grinding machine capable of continuously and automatically processing holes of different diameters with a single grinding wheel. It achieves an automatic grinding stroke (U-axis) of -3 to +50mm. Additionally, it comes standard with a full cover designed with operability in mind. By simply inputting the necessary data, it can automatically generate a differential search processing program. 【Features】 ■ Achieves a wide range of automatic grinding strokes ■ Standard full cover designed for operability ■ Compact installation space ■ Adoption of high-precision scales ■ Control panel focused on manual operation *For more details, please refer to the PDF materials or feel free to contact us.

We would like to introduce the "Jig Grinding Machine" handled by Mitsui Seiki Kogyo. The sliding surfaces of the X and Y axes are equipped with precision needle rollers on finely finished surfaces, achieving high straightness and accommodating fine feed. The lineup includes the "J3GEN," which employs a linear motor for Z-axis drive, as well as the "J300G" and "J4GDN." Additionally, the grinding head comes standard with a high-frequency motor (low-speed/high-speed), and various motors are available as options. 【Features】 ■ Achieves high geometric accuracy ■ Uses carefully selected castings ■ Hole pitch accuracy: ±1.5μm ■ Realizes high-precision hole processing ■ Automation features that support unmanned and labor-saving grinding processes *For more details, please refer to the PDF materials or feel free to contact us.

The "J750G" is a top-class jig grinding machine designed for high-precision grinding of large workpieces. In addition to being able to easily accommodate large plates, it also allows for the processing of multiple small to medium-sized workpieces. It addresses the very challenging issues of "large" and "high precision," and furthermore, it significantly expands the grinding wheel cutting stroke to broaden the possibilities for automated processing. [Features] ■ Extensive processing area ■ Achieves positioning accuracy within 2μm even with long strokes (X: 1530) ■ A rich lineup of grinding heads tailored to various applications ■ Supports the automation of high-precision grinding ■ Control panel thoroughly analyzed based on actual operations *For more details, please refer to the PDF materials or feel free to contact us.
