Precision Centerless Grinder with Direct-Connected Drive Motor and Compact Hydraulic System
The Precision Centerless Grinder is a high-accuracy grinding machine designed for centerless cylindrical grinding, small shaft grinding, pin grinding, sleeve grinding, roller grinding, precision round bar grinding, and batch production of cylindrical components. With a direct-connected drive motor, compact hydraulic system layout, stable grinding structure, and efficient space utilization, this machine provides reliable grinding accuracy, smooth operation, and practical performance for precision machining workshops.
The machine adopts a direct-connected drive motor structure, which reduces intermediate transmission links and helps improve adjustment accuracy and rotation accuracy. This design supports stable grinding performance, reduces mechanical transmission loss, and improves overall machining consistency during continuous production.
The hydraulic system fan and oil tank are arranged with full consideration of installation space. This compact layout makes better use of the machine structure and helps improve workshop space utilization. It is especially suitable for factories that require efficient equipment layout, stable hydraulic performance, and practical daily operation.
