Efficient straight edge grinding method for glass and round and straight edge double-edge machine system

Abstract

The invention relates to an efficient straight edge grinding method for glass and a round and straight edge double-edge machine system. The method comprises the following specific steps that two grinding forming devices are used for machining and forming bottom edges, upper chamfers and lower chamfers on the two sides of the glass in one step; the two chamfering and polishing devices are used for machining an upper chamfer and a lower chamfer on the two sides of the glass correspondingly for chamfering and polishing treatment; and the two bottom edge polishing devices are used for polishing the bottom edges on the two sides of the glass correspondingly. The polishing machine has the beneficial effects that the design is reasonable, the rotating speed of the polishing machine can be properly increased, the grinding and polishing processes are integrated and optimized, the purpose of high-speed and high-efficiency straight edge grinding is achieved, glass edge cracking is avoided, the glass machining quality is guaranteed, and the market requirement is met.

Description

technical field [0001] The invention relates to the technical field of glass grinding, in particular to a high-efficiency straight-edge grinding method for glass and a double-sided machine system for round and straight edges. Background technique [0002] For glass grinding, diamond grinding wheels are used for grinding, non-diamond polishing wheels are generally used for polishing, and non-abrasive glazing wheels are generally used for glazing. The existing glass straight-line double-edge grinding machine is generally driven by multiple motors to work with various functional grinding wheels, and the rough grinding, fine grinding, and polishing processes are performed at one time. The main types are straight-edge double-edge machines (such as patent CN201910244679.1) and round edges. Bilateral machine (eg patent CN201120151131.1): [0003] The straight-edge double-sided machine is used to process the bottom edge and the chamfering of both ends of the cut glass blank, common...

Problems solved by technology

[0007] At present, the linear speed of the grinding wheel of the above two types of models is generally low-speed grinding (that is, usually lower than 45 m / min), and the grinding efficiency and grinding quality are limited; because glass is a brittle and hard material, it is easy to chip , in order to ensure the yield rate, when the blank is generally cut, there is usually a large machining allowance, which forms an obstacle to high-efficiency and high-quality grinding; most grinding wheels use external cooling grinding (a small amount is low-efficiency internal cooling) , or partial section internal cooling), if high linear speed grinding is used, the cooling water is affected by the airflow barrier, most of which are in the atomized cooling mode, and the cooling capacity is difficult to meet high-efficiency processing; the softening temperature of glass is low, When the cooling or chip removal ability is poor, the glass is easy to soften or burn; when some special-shaped wheels are used, such as CNC machining centers, the external cooling mode is limited to the cooling of the lower half of the grinding wheel, and the cooling is also in the atomized cooling mode. , high-speed grinding is limited; due to the limitation of the performance of the edging machine, it cannot meet the production demand
