Product Description
adopting advanced CNC system to precisely control the rotational speed of the grinding wheel axis, the feed amount and the movement of the workpiece table, to achieve micron-level control of the parameters of internal threads (e.g., pitch, centre diameter, tooth angle, etc.), to ensure that the machined threaded parts can meet the stringent requirements of precision.
with automatic programming and compensation functions, it can adapt to the batch processing needs of many complex internal threads, greatly improving production efficiency. Meanwhile, some models are equipped with automatic loading and unloading device and online inspection system, which realises unmanned continuous production process and reduces labour cost and scrap rate.
these grinding machines can handle internal thread grinding of various steel, cast iron, non-ferrous metals and other difficult-to-machine materials, and are suitable for high-precision internal thread parts manufacturing in aerospace, automobile manufacturing, precision machinery, hydraulic components and other fields. The strong rigidity of the machine structure and good vibration damping, together with the stable servo drive system and advanced cooling and lubrication system, ensure the stability of machining accuracy and the service life of the equipment under long-time operation.
