Machine Category and Positioning
The M1420 is a universal external cylindrical grinding machine. The machine category code “M” stands for grinding machine, “1” represents the external cylindrical grinder group, “4” indicates the universal external cylindrical grinder type, and “20” denotes a maximum grinding diameter of 200 mm.
Structure and Design
The machine features a compact structure with a rigid bed design. It adopts a box-type bed to enhance rigidity, ensuring stability and precision during the grinding process. The wheelhead uses a sleeve-type static bearing design and is equipped with an independent oil tank and separate lubrication system, which improve grinding accuracy and extend equipment service life.
Grinding Capability
Suitable for grinding internal and external cylindrical and conical surfaces of shaft-type parts. It meets the needs of single-piece, small-batch, and mass production in the mechanical manufacturing industry.
Drive and Control
Equipped with hydraulic drive and electrical control systems, the machine is easy to operate and offers high grinding efficiency. The workpiece, grinding wheel, oil pump, and cooling pump are each driven by independent motors, ensuring system stability and ease of maintenance.
Application Range
Ideal for machining cylindrical and conical external surfaces, widely used for precision grinding in industries such as machinery manufacturing, automotive, and bearings.
