Ensuring Accuracy by Containing Coolant

One of the details that has been improved on a new cylindrical grinder is a casting design that isolates coolant from affecting the structure of the machine.

The word “coolant” is deceptive. Coolant in machining is a heat-transfer device. While the fluid cools the cut by transporting heat away from the work zone, it carries that heat to wherever the coolant then lands.

Toyoda says it engineered its new GE4-i cylindrical grinder in part with attention to the thermal effects that might come from heat transfer via coolant. The machine is seen here at this year’s IMTS, where it debuted. The company says the machine’s redesigned casting contributes to thermal stability by capturing and channeling the coolant that falls from the workzone in order to isolate it from the structure of the machine.

Another feature of the GE4-i is an icon-driven and user-friendly control interface, which is valuable in part as manufacturers adapt to the difficulty of finding skilled labor in grinding. More on that here.

  • Vertical Grinding Has Advantages

    In vertical grinding, the workpiece is held upright in a rotary chuck with the grinding spindle overhead. This configuration can improve roundness, facilitate single-setup processing and prolong the life of the machine. Loading and unloading may gets easier, too. Workpieces with relatively large diameters and short lengths benefit the most from vertical grinding.
