Problems solved by technology

While this method may be used satisfactorily for certain (e.g., small diameter) grinding wheels, the additional weight and associated metal plate 24 is suitable for large grinding wheels, e.g., up to 44 inches (112 cm) in diameter and weighing up to 300 lbs (136 kg). cost tends to be constrained

example 1

[0050] Glass-reinforced polyester coupons (Type 5300 and 5600 plate molding compounds from Zehrco Plastics, Inc., Ashtabula OH, USA) were fabricated into rods with a cross-section of 1 / 2 inch by 1 / 2 inches (nominal 12mm x 12mm), and were evaluated before and after firing at approximately 160°C for 10 hours to evaluate thermal stability and mechanical properties.

[0051] The mechanical strength is tested by measuring the yield strength of a sample of the material before and after firing. use 4204 (Instron Corporation, Canton, Massachusetts) electromechanical test system, to test the yield strength, the system is equipped with a span of 2 inches (5cm) Three-point bending fixture and a free-moving roller running at a feed rate of 0.5 inches (1.3 cm) per minute. As shown in Table II below, the material was found to substantially exceed the required strength of 40 megapascals (MPa), while also exceeding the optional strength of 100 MPa.

[0078] Two-component glass-reinforced polyester specimens (Premi- 1203-30, 30% glass-filled polyester, Premix, Inc., North Kingsville Ohio) is processed into rods with a cross-section of 1 / 2 inch by 1 / 2 inch (nominal 12mm by 12mm), And yield strength and tensile strength were tested essentially as described in Example 1.

[0079] As shown in Table VI below, both compositions were found to substantially exceed the required minimum and optional yield strengths of 40 and 100 MPa, respectively.

[0089] Glass-reinforced polyester specimens produced by Polyply Composition, Inc. of Grand Haven MI were processed into rods with a cross-section of 1 / 2 inch by 1 / 2 inch (nominal 12 mm by 12 mm) and rolled in Yield and tensile strengths were tested essentially as described in Example 1 before and after firing to about 160°C.

[0090] The test results shown in Tables IX-XI below indicate that these specimens met the required minimum yield strength of 40 megapascals (MPa) and the required minimum tensile strength of 500 lbs (2224 Newtons). The fired specimens failed to meet the optional optional yield strength level of 100 MPa.

Abstract

A bonded abrasive grinding wheel is provided with a bonded abrasive disc including abrasive grain disposed within a bond matrix, and a mounting plate integrally fastened to the disc. In various embodiments, the mounting plate has a plurality of non-metallic first threaded fastener portions disposed in a predetermined pattern therein, and is fabricated from a composition including a polymetric material. The non-metallic first threaded fastener portions are each configured for respective engagement with a plurality of second threaded fastener portions disposed along a face plate of a grinding machine.

Description

technical field [0001] The present invention relates to grinding wheels, and more particularly, to disc grinding wheels having an integral mounting plate to facilitate mounting to a surface sander faceplate. Background technique [0002] Grinding wheels (that is, grinding wheels) are widely used in traditional grinding machines and handheld angle grinders. When the grinding wheel is used on these machines, the grinding wheel is fixed at its center and rotates at high speed while the grinding wheel is pressed against the workpiece (ie, the workpiece). The grinding surface of the grinding wheel grinds away the surface of the workpiece by the combined cutting action of the grinding particles of the grinding wheel. [0003] Grinding wheels are used for both rough and fine grinding operations. Rough grinding is used to achieve rapid stock removal without particular regard to surface finish and burning heat. Examples of rough grinding include rapid removal of impurities from bi...
