摘要： It is an object of the present invention to provide a wheel shaft supporting apparatus for a grinding machine achieving easy assembling and disassembling of a grinding wheel supported by a pair of wheel shafts and increasing centering accuracy of both wheel shafts and stiffness in combined wheel shaft. A pair of hydrostatic radial bearing devices 42, 43 is mounted on right and left side surface of a front portion of a wheel slide 34 in order to support rotatably wheel shafts 45, 52 respectively. A thrust bearing device 45 mounted in either one of wheel shafts 45, 52 supports the either one wheel shaft 45 or 52 in a thrust direction. A shaft coupling mechanism 60 is installed in wheel shafts 45, 52 in order to assemble and disassemble wheel shafts 45, 52. A taper cylindrical portion 61 is projected from either one of wheel shafts 45, 52 and fitted tightly with a taper inside opening 65 formed in remaining of wheel shafts 45, 52. A vertical end surface 52t, 49t or Fb extending from a base of the taper cylindrical portion 61 is fitted tightly with an another vertical end surface 45t, 52t or 45t of the remaining wheel shaft 45 or 52. Wheel shafts 45, 52 are tightly fitted by two surface fitting of a taper surface fitting and a vertical surface fitting.

摘要： Disclosed is a cylindrical grinding machine of the type that a workpiece support device composed of a work head and a foot stock is mounted on a forward upper portion of a bed while a wheel head unit composed of a slide base and a wheel head is mounted on a rear upper portion of the bed. A coolant collecting vent which takes a rectangular shape as viewed from above vertically extends in the bed and opens to the upper surface of the bed to cover an area that extends from under the workpiece on the workpiece support device to under the forward portion of the wheel head unit. A horizontal vent is provided in the bed to open to the rear surface of the bed and to communicate with the collecting vent. A coolant supply device is inserted at a part thereof into the horizontal vent from the rear surface of the bed to extend an inlet opening into the collecting vent. In one embodiment, the slide base is mounted to straddle over the collecting vent and is guided at both ends thereof on the bed to be movable back and forth, and the wheel head is guided to be movable on the slide base in a right-left direction. In another embodiment, the part of the coolant supply device inserted into the horizontal vent is constituted as a discharge duct, from which a mist discharge duct branches upwardly to be connected to a mist collecting device. Airflow blocking means is provided for permitting the coolant to flow through but for blocking airflow from an outlet port of the discharge duct toward the mist discharge duct.

摘要： A grinding head guiding apparatus is disclosed. The grinding head is driven by the linear motor which is constituted of a coil attached on an underside surface of the grinding head and a magnet attached on an upside surface. Horizontal guiding members are fixed on the base, and the grinding head is guided to the horizontal guide members. Then, a height of a portion opposing the coil and the magnet is approximately same as a height of the horizontal guide members guiding the grinding head. Besides, temporary supporting members are attached on the base so as to avoid sticking the coil to the magnet, when the coil is detached from the grinding head. Further, the grinding head has ribs therein, which define an approximately trapezoid-shaped space disposed a center of the grinding head and triangle-shaped spaces disposed both side of the trapezoid-shaped space.
