CYLINDRICAL GRINDERINTRODUCTION
TOPKING CNC Cylindrical Grinder - OGC series is your best choice for high precision grinding work. The X-axis and Z-axis are both driven by precision ball screws and servo motors. They are equipped with a high-performance CNC control system and a built-in graphical (GUI) operation interface. The grinding is widely applied, making the operation and processing closer to the needs of users.| CAPACITY
Swivel Over Table: Ø250 mm
Distance Between Center: 300 mm
Max. Grinding Dia.: Ø250 mm
Grinding Wheel: Ø355 x 50 x Ø127 mm
MACHINE FEATURE
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
■ The machine’s structure is different from the light weight design philosophy in the past; it substantially consolidates the rigidity of machine
HYDROSTATIC LUBRICATION SYSTEM
■ The slideways of the table and the wheel head are lubricated by an advanced automatic hydrostatical lubrication system.■ The lubrication performance of the worktable and the wheelhead has been significantly enhanced, showcasing exceptional grinding smoothness. Moreover, with the optimized operational fluidity, it becomes possible to achieve higher precision in the feed rate, ensuring the accuracy of the machining process.
WHEELHEAD CONSTRUCTION
■ 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 work spindle utilizes precision-grade bearings, showcasing optimal stability.
■ The workhead is driven by a servo motor, enabling continuous and infinitely variable speed adjustments based on demand.
■The workhead features a fixed-type work spindle, enhancing accuracy and stability.
■ The tailstock lubrication adopts an oil-bath lubrication system, ensuring consistent high precision of the tailstock at all times.
■ The lubrication system is equipped with an oil gauge for convenient monitoring of oil quantity by operators.
DIAMOND TOOL HOLDER
(slider mounted type)
■ The dressing device is affixed to the Z-axis slide, minimizing errors caused by repeated dressing position calibrations due to adjustments in the worktable angle.
■ Diverse dressing device is available, adaptable to the requirements of the component.
