Double disc grinding machine is mainly used for grinding two opposite planes of the workpiece, with high processing efficiency, high dimensional accuracy and high degree of automation, and is widely used in the automotive, hydraulic, gauging, sharpening, bearing, precision ceramic and other industries with typical processed part types.

Matching dressing grinding wheel
The dressing wheels are used for dressing diamond and CBN wheels. According to the different particle size, accuracy of the diamond and CBN grinding disc to choose the dressing wheel, making dressing easier and more time saving.

What is double disc grinding?
Double disc end face grinding technology is a must to find an efficient grinding solution to meet various requirements of the workpieces. A wide range of grinding tasks and a large variety of work, which require more precision and flexibility of grinding itself. The face grinding especially double face grinding is necessary.

Double disc grinding(DDG), also called double face grinding, is a highly efficient method of removing equal stock from opposing faces of a part, normally symmetrical stock removal. The Double Disc Grinding process will also produce the highest level of Flatness and Parallelism on opposing surfaces.

Generally, Double Disc Grinding is used for high productivity however production rates can vary greatly from over 40,000 parts per hour to just a few parts per hour depending on the disc grinders tooling configuration, part size, material, and stock removal.
