MK2840 Vertical CNC Internal And Face Grinder

The machine tool adopts the technical plan by using plane emery wheel grinding bore and end face in sequence. With small inclined angle between wheel axis line and Z axis feeding direction, grinding end face adopts plane concave emery wheel, emery wheel end face and grinding surface is realized by line contact, which can improve emery wheel grinding and cooling as well as improve end face grinding quality.

The machine tool is suitable for finish grinding large disc type parts, especially for mass production of high precision parts, such as automobile gears machining, the bore grinding roughness can reach Ra0.4m, end face grinding roughness can reach Ra0.8m. While by the

Operation of semi loop control limit stroke grinding, the grinding size control accuracy can reach grade 6-7. The machine can be applied to external grinding of disc type parts as well.
