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 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.
■ X-25 series adopts precise linear guides and ball screw design for the two-axis movement. The linear guides are designed to be wear-resistant and have low-friction properties, ensuring that the axis seat moves smoothly. The ball screw can handle high loads and has low backlash, which allows for a quick and flexible feed mode, achieving the required dimensions rapidly. This integrated combination offers a fast and responsive feed mode, delivering outstanding machining quality for small component.

■ 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 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.


 ( tailstock mounted type)

■ Standard dressing device is mounted on tailstock
■ Diverse dressing device is available, adaptable to the requirements of the component.
■ ptional: Diamond roller Dressing Device (worktable mounted type)
