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.
