Stone grinding device in particular for skis

Grinding devices are known in which the ski |

between a rigid but axially oscillating stone '

sanding roller and a manually adjustable feed roller *
is ground from the tip.

This arrangement has the disadvantage * that the ski because of its
Shape when grinding the tip at the transition to the tread
performs a pivoting movement.

When combined with other automatic machining processes, such movements of the workpiece are very disadvantageous, because a simultaneity before machining operations in this swivel range cannot be carried out.

Furthermore, with the known stone grinding machines, P

Stone removal mechanisms provided, this is required ■

since at the reversal points of the oscillation there is no removal on the |

Stone takes place * ί

In the case of the innovation described below, the |

Stone grinding roller by swiveling the respective I.

Shape of the ski, further it is through the storage combination - |

8 Grinding pin bearings and axial bearings for the oscillation - ) possible with little technical effort, under intermediate |

circuit el. control the oscillation reversal positions, I

to steer towards the current ski width. Thereby j

can do without complicated stone removal mechanisms \

will.

In order to achieve an optically good micrograph, one is required

stable mounting of the rocker required =

In Ainet cantilevered hollow axle (2) Met is axially slidable and in the grindstone (1) is mounted by the intermediary of a spindle (S) pivotably mounted a rocker (9), in that the grinding wheel drive can be disposed outside the wet area *

A very stable pivot point bearing can be achieved by counter-bearing (longitudinal u * rotary bearing) of the oscillating rod (3) create for the rocker (9) (10) attached) so that the overall mechanism approximated is indifferently pivotable * or by displacement the balance weight (10) generates a torque that of resetting the sanding unit to its starting position, as well as generating the grinding pressure *

This arrangement makes it possible to precisely set the oscillation end positions by means of 2 easily adjustable limit switches to be coordinated with the outer edges of the ski, which means that the pulling mechanism can be omitted as the whetstone over the entire length Width is in use.
