Product
The machine design for use in automative industry ,precision component manufacturing.
SMK304 CNC Internal Thread Grinder
-Grinding for Internal Thread and circular INQUIRY● The grinding machine is professional to processing in ball nut of Internal thread, cylindrical and ending surface for once clamping.
●T type mineral casting frame get better in vibrating and heat distortion.
●The diamond dressing wheel install on Z axis, and let grinding wheel dressing amount can be compensated automatically
●A axis motor let internal grinding wheel to swing angle +-25° by automatic program.
Machine tool structure diagram |
T type granite base stand,keep high precision and small expansion |
A axis motor let internal grinding wheel to swing angle +-25° by automatic program. |
Internal thread grinding wheel is motor spindle , speed 500-24000rpm. |
When using diamond wheel to dressing grinding wheel ,X axis and Z axis will interpolation dressing together. |
