CYLINDRICAL GRINDERINTRODUCTION
TOPKING Cylindrical Grinder – T series is suitable for step grinding. The X and Z axes are driven by NC servo motors with ball screws. Eliminate the complicated program editing of traditional CNC control systems. The T-Series is equipped with a high-performance control system with GUI. Provide the most convenient operating environment for the operator.| CAPABILITY
Swivel Over Table: Ø270mm
Distance Between Center: 300 mm
Max. Grinding Dia.: Ø250 mm
Grinding Wheel: Ø355 x 50 x Ø127 mm
MACHINE FEATURE
HIGH PERFORMANCE GRAPHICAL USER INTERFACE
■ TOPKING's latest graphic dialogue operation interface provides the operator with the most convenient, simplest and safest operating environment.
■ Different from the previous program editing, the numerical programming setting can automatically execute the grinding cycle, dressing cycle, correction and other commands.
■ It can memorize the coordinates of mechanical origin, grinding, dressing, compensation with one key.
■ Various grinding and dressing methods can be selected according to the needs of the work.
RIGID MACHINE BASE
■ The structure of the machine is different from the previous lightweight design concept; it greatly strengthens the structural rigidity of the machine body and parts. In pursuit of more stability, it adopts a thicker and stronger sliding seat mechanism, the slideway 1V 1 flat structure, and a lubrication system designed by the principle of static pressure, providing the best precision and stability when grinding.
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.
