On the development history of double-sided grinder
Do you know the history of the development of double end grinders. In the 1830 s, in order to adapt to the processing of hardened parts such as clocks, bicycles, sewing machines and firearms, the United Kingdom, Germany and the United States developed double-end grinders using natural abrasive wheels. These double-end grinders are made by adding grinding heads to off-the-shelf machine tools such as lathes and planers at the time. They are simple in structure, low in rigidity, and prone to vibration during grinding. Operators are required to have high skills to grind out precision workpieces.
The excircle double-end grinding machine produced by the American company exhibited at the Paris Expo in 1876 is a machine with the basic characteristics of modern double-end grinding machines. Its workpiece head frame and tailstock are installed on a reciprocating worktable. The box-shaped bed improves the rigidity of the machine tool and is equipped with internal grinding accessories. In 1883, the company made the grinding head mounted on the column, the worktable for reciprocating planar double-end grinding machine.
Around 1900, the development of artificial abrasives and the use of hydraulic transmission have greatly promoted the development of double-end grinders. With the development of modern industry, especially the automobile industry, various types of double-end grinders have come out one after another. For example, at the beginning of the 20th century, successively developed the processing of cylinder block of the planetary inner circle double-end grinding machine, crankshaft double-end grinding machine, camshaft double-end grinding machine and magnetic suction cup piston ring double-end grinding machine. The active measurement device was applied to the double end face grinder in 1908.
Around 1920, double-end grinding machines, double-end grinding machines, roll double-end grinding machines, guide rail double-end grinding machines, honing machines and ultra-finishing machines were successively made and used. In the 1950 s, high-precision cylindrical double-end grinding machines capable of mirror grinding were presented. In the late 1960 s, high-speed double-end grinding machines with grinding wheel linear speed of 60~80 m/s and double-end grinding machines with large cutting depth and slow feed grinding plane grinding were presented.
