The KOYO HD7 is a large surface grinding machine designed for precision grinding tasks. This model features dual grinding units, each equipped with substantial grinding wheels measuring 760 mm in diameter and 90 mm in width, with a bore size of 25 mm. The grinding wheels operate at a no-load speed of 740 revolutions per minute and can achieve a maximum peripheral speed of 1765 meters per minute, making them suitable for handling sizable workpieces. The maximum grinding range is approximately 250 mm in diameter by 80 mm in width, accommodating a variety of surface grinding applications.
The machine is CNC-controlled, utilizing a Mitsubishi computer system, which allows for precise and programmable grinding operations. The control panel is mounted on the right side and features a touchscreen display along with multiple labeled buttons and switches such as POWER, COOLANT ON/OFF, START, STOP, RESET, EMERGENCY STOP, and EXECUTE, facilitating user-friendly operation and control. Additional instrumentation includes two analog ammeters labeled L.G.W and R.G.W, providing monitoring of grinding wheel currents.
Built with operator convenience in mind, the machine includes a step platform on the left side to allow easy access to the working area. Protective green covers shield the grinding wheel spindles, and various adjustment knobs and levers are situated near the grinding units for fine-tuning the grinding process. The machine’s exterior shows no visible signs of damage or rust, and the components appear clean and well-maintained. Visible piping and wiring are neatly arranged on the machine’s body.
This surface grinder is suitable for industrial environments requiring robust and accurate grinding capabilities. Please note that while the machine appears to be in good condition, no information about recent testing or overhaul status is provided beyond the indication that overhaul has been finished.
