Improvements in or relating to abrasive wheel guards

... 621,572. Supplying coolant to grinding- wheels. BALLINGER, L. J. H. May 30, 1946, No. 16478. [Class 60] A guard, for a high-speed abrasive wheel, has ducts through which cooling water passes to the wheel, the arrangement being such that a water pressure is developed against the face of the wheel. The guard comprises two portions, each of which is formed with passages d, e, through which water flows from inlet f to semi-circular passages g, h, formed on the inner faces of the guard. The passages g, h, connect with wedge-shaped radial grooves k, Fig. 4, formed on the inner faces of the guard. Due to the relation of grooves k to the direction of rotation of the wheel i water pressure is developed against the face of the wheel, thereby cooling it and forming a hydraulic support on either side of the wheel.

A grinding machine for grinding short components has a grinding enclosure 18 in which the grinding operation takes place. The grinding enclosure contains the grinding wheel, a workpiece holder and a wheel dressing station, but all other components of the machine are mounted outside the enclosure, so as to be kept out of contact with coolant and swarf. The enclosure is sealed, to an extent sufficient to prevent egress of coolant and grinding debris and has openable doors to allow loading and unloading of workpieces and mounting and removal of grinding wheels.

Coolant supply method and apparatus for grinding machine

In a coolant supply method and apparatus for a grinding machine, when an end surface of a workpiece is ground with a grinding wheel end surface (Ga,Gb) of a grinding wheel with coolant being supplied toward a grinding point (P), a first coolant flow (24) is ejected toward a first position which is on the grinding wheel end surface on an upstream side of the grinding point (P), and intercepts an air layer (28) rotating to follow the grinding wheel end surface. At the same time, a second coolant flow (25) is ejected toward a second position which is on the grinding wheel end surface and which is closer to the grinding point (P) than the first point, and clings onto the grinding wheel end surface at the second position where the follow air layer (28) has been intercepted by the first coolant flow. Thus, the coolant of a sufficient volume can be supplied to the grinding point (P) where the grinding wheel end surface grinds the end surface of the workpiece.

A PROCESS AND AN APPARATUS FOR SUPPLYING THE INTERFACE BETWEEN AN ABRASIVE TOOL AND A WORKPIECE WITH COOLING LUBRICANT

The present invention relates to a process to supply the interface zone between an abrasive tool and a work piece with cooling lubricant. This process incorporates the following steps: a) provision of an annular gap (4) around the outside contour (5) of the abrasive tool (1), said annular gap (4) extending around the major portion of the periphery of the abrasive tool (1); b) interruption of the annular gap (4) in a first area (6) in which the interface zone (3) between the abrasive tool (1) and the work piece (2) is located; c) interruption of the annular gap (4) in a second area (7) that is located in an area of the periphery of the abrasive tool (1) that is spaced apart from the first area (6); d) delivery of cooling lubricant to the second area (7). This means that the cushion of air that forms around the rotating abrasive tool is broken down, so that even a small flow of oil will be sufficient to cool and lubricate the interface between the tool and the workpiece effectively.

An arrangement for cooling a spindle bearing or bearings (3) of an abrading apparatus with rotating abrading members is disclosed, premised on arranging in the housing (2) of the abrading apparatus conduits (1) which extend from the spindle bearing chamber wall (6) of the housing (2) to the inner suction chamber wall (8) of the housing (2). Via such conduits (1), hot air may be expelled from the spindle bearing chamber (5) of the housing (2) as an overpressure (O) in front of a protruding balancer element (16) of a rotating shaft balancer (10) is discharged from a spindle bearing chamber (5) via a conduit (1) into a suction chamber (7), and cool air may be conveyed from the suction chamber (7) into the spindle bearing chamber (5) as an underpressure (U) behind the protruding balancer element (16) draws in air from the suction chamber (7) via a conduit (1) to the spindle bearing chamber (5).

Abrading device having a front exhaust

Automatically adjustable protection device for a grinding wheel

A protection device for a grinding wheel includes a containment structure having an operating opening for a grinding wheel, wherein the containment structure includes a fixed portion and a movable portion which can be moved with respect to the fixed portion by means of a motor and which can be blocked with respect to the first fixed portion by means of a magnetic blocking unit. The device further includes a sensor adapted to automatically detect the position of the movable portion, and a control means of the entire device.

Escudo protector y distribuidor del refrigerante para una rectificadora.

Escudo protector y distribuidor del refrigerante para una rectificadora. El escudo protector (3) en forma de visera báscula alrededor de un eje (10) propio para mantener una distancia (4) con la periferia (1b) de la muela (1) en la medida de su desgaste. La basculación es automática mediante medios autónomos impulsado por un vástago (9). El distribuidor (5) es desplazable e incorpora las boquillas (15) que enfocan continuamente la zona de mecanizado. Su desplazamiento se efectúa sin la utilización de medios motrices propios, mediante una carcasa (5b) móvil soporte de las boquillas que aloja un eje (11) de deslizamiento, una roldana (16) fija al escudo (3) la cual recorre una ranura corredera (17) inclinado perteneciente a la pared lateral de la carcasa (5b) soporte haciendo que ésta se desplace con el escudo (3).
