Overall Machine Structure Features

The machine body is made of HT300 cast iron and undergoes secondary annealing to completely eliminate casting stress and internal stress generated during rough machining. This ensures structural rigidity and stability, meets the requirements of heavy - duty cutting, and guarantees long - term non - deformation performance. The spindle system (including all key components) is imported from professional manufacturers in Taiwan and is reinforced. It uses P4 - grade spindle bearings from world - renowned brands and high - quality lubricating grease. After assembly in a constant - temperature environment, the entire spindle system undergoes computerized dynamic balancing and running - in tests to ensure long service life and high reliability. The ball screws for the three - axis drive are all imported, and both ends of the screws are equipped with imported P4 - grade universal ball screw bearings. All three - axis ball screws are pre - tensioned to ensure strong transmission rigidity and stable precision. Key parts are precisely scraped (lapped) according to the advanced standards of tool factories in Taiwan, Japan, and Germany to ensure the geometric accuracy of all mating and sliding surfaces, thus guaranteeing the machine's accuracy requirements and service life. Through a comprehensive quality inspection process, combined with advanced equipment such as automatic optical collimators, laser interferometers, ball bar testers, and online dynamic balancing instruments, as well as a 72 - hour running - in test before delivery, each machine is ensured to meet the designed performance and functionality requirements upon leaving the factory.

X - Axis Design Features

The guide rails use high - rigidity and high - precision roller linear guides from internationally renowned manufacturers, combining excellent performance for heavy cutting and high - speed precision.

The X - axis is designed with a two - rail or three - rail structure, paired with densely arranged sliders to form a stable support structure, ensuring optimal rigidity and flatness, and effectively improving the load - bearing capacity of the workbench and the dynamic horizontal accuracy of the workpiece.

Y - Axis Design Features

Key parts are precisely scraped (lapped) according to the advanced standards of tool factories in Taiwan, Japan, and Germany to ensure the geometric accuracy of all mating and sliding surfaces, guaranteeing the machine's accuracy and service life.

It uses the same high - quality transmission system as the whole machine: imported ball screws with P4 - grade bearings and pre - tensioning, combined with constant - temperature assembly and dynamic balancing tests, to ensure transmission rigidity and precision stability.
