14 types of grinding machines [working, diagram & pdf]

Machines in which grinding wheels are fitted and grinding is done, such machines are called grinding machines. On the basis of their function, they can be divided into two parts. Ordinary grinding machines which are widely used. These are called rough or snagging grinders. The following types of grinders are included in this category

This types of grinding machines are fixed on a workbench or table. Gear or pulley is fitted in it. For rotating the big-size gears or pulley a handle is also fixed. It contains one or two grinding wheels. Edges of cutting tools can be made with this grinder. Provision can be made to operate these with power also

This types of grinding machines are operated with electric power. This is fitted on a pedestal frame separately on the ground. A grinder wheel is fitted each on both sides of the shaft of the electric motor.

Tools rests are also provided with them. These are the most widely used in the workshops. Edges of all types of cutting tools are made with these grinders. Apart from this, molded articles can also be cleaned with it

Primary Examiner-Harold D. Whitehead Attorney-N0rman Blodgett [57] ABSTRACT This invention relates to a grinding machine and, more particularly, to a system for preventing thermal damage in abrasive machining and finishing by measuring abrasive wheel dullness and providing for a renewal of the wheel surface when the dullness reaches a preselected value.

BACKGROUND OF THE INVENTION In the manufacture of certain machine parts, such as jet engine parts and anti-friction bearing raceways, a problem often arises known as thermal damage. This usually consists in loss in metallurgical properties and is generally understood to be due to heavy feed rates or force intensities. However, thermal damage can also be caused even with finish grinding forces when the grinding wheel is dull. Consequently, thermal damage is related to two important factors: force intensity and wheel dullness. It is difficult to operate an automatic grinding machine at its optimum efficiency without exceeding the permissible limits of the above factors and causing thermal damage. These and other difficulties experienced with the prior art devices have been obviated in a novel manner by the present invention.

With these and other objects in view, as will be apparent to those skilled in the art, the invention resides in the combination of parts set forth in the specification and covered by the claims appended hereto.

SUMMARY OF THE INVENTION In general, the present invention has to do with a grinding machine having a base, having a workhead mounted on the base to support a workpiece having a surface of revolution to be finished by the abrasive process, having a wheelhead also mounted on the base and having a rotatable spindle carrying an abrasive wheel, having feed apparatus to bring about relative movement between the workhead and wheelhead to introduce the wheel to the workpiece for performing a grinding operation to finish the said surface of revolution, and having means operative when wheel dullness exceeds a predetermined value to bring about renewal of the wheel surface.
