Many machining companies want to choose domestic machine tools to replace imports, but during the selection stage, they are prone to various misunderstandings: only looking at promotional sample parameters, ignoring the long-term accuracy maintenance of machine tools; Blindly pursuing high-end equipment, many functions are not actually needed in production, which raises the procurement budget; Only concerned with procurement prices, neglecting the comprehensive costs of later operation and maintenance, spare parts, and process services; Assuming that the same parameters result in the same effect of processed parts, ignoring implicit indicators such as bed rigidity, heat treatment, and factory inspection. The true measure of the quality of a machine tool depends on its actual performance during long-term mass production, rather than the theoretical parameters listed in the sample book.
When choosing a CNC lathe or milling compound, the first thing to pay attention to is the basic hardware. The material of the bed casting and the aging and stress relief process directly determine the accuracy and service life of the machine tool. The entire base and saddle of Harman Precision Machinery are made of high tension Mihanna cast iron, which is integrally formed. Multiple aging treatments are used to eliminate internal stresses during casting, and FEM finite element simulation is used to optimize the structure, reducing the risk of deformation in the later stage from the source. The core transmission components are selected from THK, NSK, and FAG international first-line accessories, and each equipment completes multi-dimensional running in and accuracy verification before leaving the factory.
Selection rejects blind stacking of configurations, distinguishing between standard and optional configurations. Automatic robotic arms and high-end systems are selected as options, and enterprises can increase or decrease according to their own workpiece needs to reduce unnecessary expenses. At the same time, it is necessary to attach importance to service capabilities. Machine tools are only carriers, and processes, debugging, and maintenance are the key to ensuring production.
After purchasing equipment, many companies encounter a lack of process support for new workpieces, resulting in slow response to fault reports and production line shutdowns. Harman Precision Machinery has a nationwide localized service network, providing pre-sales process evaluation, in sales installation training, after-sales remote diagnosis, on-site repair, regular inspections, and free process optimization. Enterprise selection should not only compare prices, but also take into account the full lifecycle costs including procurement, operation and maintenance, and downtime losses, and choose equipment with balanced hardware, process, and service capabilities.
