straight type G.W. | X series


plunge grinding


The X series CNC cylindrical grinding machine integrates advanced design and innovative features, offering efficient, precise, and flexible machining solutions. This grinder can meet various processing needs and ensure high-quality results for small or large components.

The X-axis and Z-axis of the X series CNC cylindrical grinding machine adopt a cross-slide design, effectively reducing the footprint and axial travel, saving production space. The high-rigidity machine body and the heavy-duty spindle and tailstock significantly increase the component load capacity.

The high rigidity machine body ensures stability during grinding, providing high-quality machining results. The operating system is equipped with a high-performance CNC control system and a built-in graphical user interface (GUI), making setup easy and enabling users to operate with ease. The grinding applications are extensive, offering customers the most suitable machining solutions.

The built-in advanced CNC control system is equipped with GUI. The operator can divide the complex component into several grinding processes through the guidance of the graphic, and simplify the process editing of grinding, and dressing in a numerical way. No complicated programming (G code, M code) is required, and the most convenient operating environment is provided.


■ High rigidity machine base made of Meehanite cast iron through annealing and aging treatment.
■ Slideway though high-frequency hardening and precision grinding process. Machine base with stable material and strengthen construction for deformation-free and outstanding wear resistance. 
■ The machine’s structure is different from the light weight design philosophy in the past; it substantially consolidates the rigidity of body and parts structure, takes being more stable as the appeal, and adopts thick and solid sliding seat mechanism, slide way 1 V 1 flat structure providing the best precision and stability of moving when doing grinding.

■ The work table is permanently bolted to the machine. The cross slide design is adopted to reduce the travels. It can improve working speed and precision stability.
■ X axis and Z axis are design as cross-slider to reduce machine space. 
■ Two axes cover by enclosed telescopic covers. To protect the transmission structure and prevent contamination from grinding debris and coolant.

The X-35 series adopts a high-rigidity hard rail structure design, ensuring continuous maintenance of outstanding precision and stable machining quality under high load processing. Paired with large-diameter grade ball screws, it further enhances the load capacity, enabling the machine to perform exceptionally well in machining heavy components. This optimized design guarantees smooth movement of the grinding wheel axis and worktable, reducing vibrations during the machining process and ensuring superior machining quality.


■ Bearing type of G.W. spindle adopts precision bearings, which has a long service life and is relatively easy to replace, repair and maintain.
■ The G.W. spindle is made of high-quality alloy steel SNCM-220, which has undergone multiple treatments such as normalization, quenching and tempering, carburizing heat treatment, and cryogenic treatment. Afterwards, precision grinding and mirror treatment are carried out, and the surface hardness reaches above HRC62°. Guarantee no deformation, wear resistance, high precision forever.


■ The workhead and tailstock are specially designed for heavy component, with strong structural rigidity, which increases the overall load capacity.
■ The workhead is driven by a servo motor with step-less variable speed change.
■ Hydraulic tailstock (opt.) with support for easy operation.
■ Both the workhead and the tailstock are designed with flat air pressure design, which is easy to move, reduces friction and increase using life.
■ The cooling system is installed in the center to prevent the contact surface of the center hole from being heated and deformed.



■ Dressing device is fixed on the side of the swivelling working table. It can reduce the error caused by re-calibrating the dressing position due to the adjustment of the angle of the work table, and improves efficiency.
■ Diversified diamond tool holder types can be selected according to the workpiece requirements.
