三栄エンヂニアリング List of Products and Services

Our vertical axis circular table surface grinder, the "GSR Series," is equipped with a highly user-friendly touch panel control interface. 【Excellent Operability Supporting High Performance】 The front-focused control panel, which excels in operability, along with our proprietary software, allows for easy adjustment of grinding conditions directly on the touch panel. It offers excellent workability with extensive front operation space, making it easy to change grinding wheels and remove workpieces. 【Speedy Operations】 With the ability to automatically control table rotation and set rough grinding (1-25 rpm) and fine grinding (1-25 rpm) as needed, high-precision grinding is achievable. A knee switch for table movement that allows for hands-free operation is also included for convenience. *For more details, please contact us directly.

• Vacuum Equipment

Our vertical axis circular table surface grinding machine, the "GSR Series," is equipped with a vacuum system for securing the workpiece during grinding. 【Vacuum System】 It consists of a combination of a vacuum pump, vacuum tank, vacuum solenoid valve, positive pressure solenoid valve, and check valve, among others. 【Ideal for Grinding Non-Magnetic Materials】 The workpiece is secured by vacuum during the grinding process. The grinding fluid that is drawn in during the grinding of the workpiece accumulates in the vacuum tank, and after grinding is completed, the grinding fluid stored in the vacuum tank is returned to the grinding fluid tank using positive pressure, while simultaneously lifting the workpiece off the vacuum chuck for removal. This mechanism eliminates the need for fixtures to hold the workpiece, allowing for the grinding of non-magnetic materials. *For more details, please contact us directly.

• Vacuum Equipment

The "KRT-110 model" is a machine that performs a complete overhaul modification and NC retrofit of the KRT series owned by customers. By moving the reference surface of the anchor stone head, it is possible to increase the rigidity of the machine. By changing to ball screws and AC servos, accurate and stable cutting can be achieved, and by combining it with our developed NC fixed-length device, work efficiency is dramatically improved. The KRT series transforms into a uniquely different machine by merging with our technology. 【Features】 ■ Increased rigidity through the movement of the reference surface of the anchor stone head ■ Efficient use of diamond and CBN anchor stones ■ Achieves accurate and stable cutting ■ Combination with a DC braking system reduces the deceleration time of the anchor stone motor *For more details, please refer to the PDF document or feel free to contact us.

The "MPG-1775 model" is a slicing machine that ensures high rigidity by adding reinforcements to the appropriate areas of thick steel plates and welded structures. The Z-axis, which significantly affects machining accuracy, features a more rigid cast structure with minimal resonance and aging changes. To accommodate multi-stone processing, a spindle with a longer distance between bearings has been adopted. The fully enclosed cover prevents cutting chips and other debris from scattering outside. 【Features】 ■ Reinforcements added to the appropriate areas of thick steel plates and welded structures to ensure high rigidity ■ Properly weighted spindle head prevents lifting during groove grinding ■ Spindle with pressure-controlled labyrinth structure prevents sludge intrusion during groove grinding ■ Utilizes hardened and polished overhang-less rectangular sliding surfaces ■ Fully enclosed cover *For more details, please refer to the PDF document or feel free to contact us.
