This machine tool is a single axis CNC semi-automatic internal cylindrical grinder, mainly used for grinding the inner holes of workpieces with a diameter of less than 50 millimeters.
The machine tool bed is made of cast iron casting, with a compact structure, good stability, and strong rigidity.
The machine tool is a semi-automatic cycle, and the grinding feed rate, grinding speed, and dressing speed are automatically converted.
The setting and adjustment of machine tool parameters adopt a touch screen form, which enables human-machine dialogue and intuitive and convenient operation.
The feed of the machine tool is driven by a Mitsubishi servo motor from Japan through a coupling to move the ball screw. The guide rail adopts a cross shaped roller steel guide rail, which has high precision and good rigidity.
The hydraulic part of the reciprocating motion of the workbench is automatically controlled by PLC.
The clamping of machine tool workpieces is available for users to choose from various fixtures such as three jaw chucks, pneumatic fixtures, hydraulic fixtures, and film fixtures.
The grinding wheel shaft adopts a high-speed electric spindle, controlled by a static frequency converter, to achieve stepless speed regulation.
