Large CNC Machining Capabilities

Our largest machining center features XYZ travel of 50m x 8m x 7m while our largest vertical lathe machine features a maximum swing of 22m and 6.65m Z-axis travel capacity. We have 209 sets of heavy duty CNC machining tools, including horizontal boring mills and vertical mills with multiple axes of high-resolution machining motion. Built-in rotary tables allow us to machine complex workpieces in a single setup. Our manufacturing staff is exceptionally proficient in designing custom fixtures that improve the machining process and allow us to achieve a high degree of precision and speed.

Our Equipment List

Industry Focus

Our heavy component machining is frequently used in industries where vehicles, equipment, and machinery tend to be larger than those in typical applications. This approach is used to manufacture parts for a variety of industrial equipment across many industries, such as:
Construction: Excavators, trucks, cranes, bulldozers, pile drivers
Mining: Trucks, tractors, loaders, etc.
Agriculture: Tractors, plows, balers, etc.
Aerospace: Turbines, aircraft, satellites, etc.
Power generation: Gas and wind turbines,etc.
Industrial: various tube sheets and baffle plates, flanges, gears, etc.

Quality Assurance

One of the essential workhorses for product verification is our Coordinate Measuring Machine(CMM). We use it every day to qualify rapid prototypes and machined parts that have complex geometries with tight tolerances.

At Present, we have two ZEISS CMMs-MMZ G large bridge CMM and ACCURA II bridge CMM, and one laser tracker Leica AT901. 

Our quality assurance program is focused on providing confidence that quality requirements will be fulfilled, both by our internal staff and through our clients’ expectations.
