Our Processing Capability
Company has Welding workshop, Scraping workshop, Rough processing workshop, No.1 Finishing workshop, No.2 Finishing workshop, Precision Grinding workshop, Assembly workshop.
Sand blasting machine, Lathe，Milling machine, Planing machine, Drilling machine, Grinding machine, Boring lathe, Wire cutting machine, Gear hobbing machine, precision CNC machine tool, CNC machine center,ect. Totally more than 70 sets.
We produce 95% spare parts of screw cold heading machine,steel ball cold forming machine, and screw auto packing machine.To ensure the controllable of parts quality, and then from the technology to the process, from processing to testing, dynamic control, quality inspection and follow-up is carried out, to ensure that the each process of parts production is strictly up to the design and manufacturing standards.
Aging Treatment
Aging treatment, we place the raw materials outdoors to let them be wind and rain, rusty, look dirty, because we do not have a warehouse to store raw materials? Don't pay attention to the quality of raw materials? The answer is no, of course!
We place the raw materials outdoors, relying on the strength of nature, after months to years of wind, sunshine, rain and seasonal temperature changes, causing repeated temperature stress to the component. After the vibration aging, the dynamic stress and the residual stress of the work-piece are eliminated, so as to prevent the deformation and cracking of the work-piece, and to stabilize the size and geometric precision of the work-piece.
Welding and Scraping
Welding workshop: welding base of machines, welding parts, etc.
Scraping workshop: it is difficult to achieve the best result if only using surface grinder and guideway grinder.
Manual scraping is a necessary processing technology for high-grade machine tool, cast iron flat plate and precision measuring equipment.
Scratch: The first function of scratch is to be aesthetics, the second is the function of accumulating lubricating oil. Common patterns are: twill pattern, swallow pattern and fish scale pattern and so on.
Rough processing
Rough processing workshop: rough processing of blank parts and components after aging treatment is carried out first.
Defects of the blank, such as sand holes and air holes and insufficient machining allowance, can be found in time.
It is easy to repair or decide to scrap in time, so as to avoid waste of working hours and costs after continuous processing.
Semi-finishing and Finishing
Finishing workshop 1, 2: CNC precision machine tools, machining center, are used for fine turning, fine planing, fine milling, fine drilling, fine boring, fine filing, etc of rough and semi-rough parts.
Machining precision is 1% mm, tolerance grade is above IT5, surface roughness Ra is below 0.1μm.
Precision grinder workshop: semi-finishing and finishing precision is up to IT8-5 or higher, the surface roughness of precision grinding is Ra0.16-0.04μm.
Assembly
Assembly workshop: two engineers, 2 masters with more than 30 years of assembly experience.
5 masters with more than 15 years of assembly experience.
8 teams.
Alternate work of two eight-hour shifts each day.
