USER FRIENDLY OPERATION SYSTEM
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.
RIGID MACHINE BASE
■ 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.
WORK TABLE
■ 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.
CROSS-SLIDER DESIGN
■ 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 axis and Z axis equip with high enclosed linear scales as standard accessories, for controlling positioning accuracy and finish quality.
FLEXIBLE FEED DESIGN
■ X- A 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.
ANGULAR TYPE WHEEL HEAD CONSTRUCTION
■ 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.
WORKHEAD AND TAILSTOCK
■ 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.
DIAMOND TOOL HOLDER
( tailstock mounted type)
■ Standard dressing device is mounted on tailstock
■ Diverse dressing device is available, adaptable to the requirements of the component
