Works Tour
The Tsuchiura Works is an integration of advanced production technologies. Take a look at our well-developed manufacturing process.
3D-CAD (3-Dimensional Computer-aided Design System)
Our design centers use a 3-Dimensional Computer-aided Design System (3D-CAD) and share 3D-CAD data with related sections. This allows us to shorten development lead time, and also to standardize and automate parts design. In addition, the sytem enables dynamic computation of booms and arms, and simulation of drive mechanisms at the same time. This contributes to improved productivity and stable product quality.
Welding
Structural welding is carried out by highly advanced welding robots developed by HCM with welding technology that has attracted worldwide attention. HCM has supplied such welding robots to its partner companies abroad, where they are playing a major role in improving productivity and product reliability.
Assembly
This assembly line is exclusively for hydraulic excavators. It operates on a mixed-flow basis whereby excavators of various kinds, ranging from 10-ton to 40-ton models, are produced in a single production line in accordance with our customers’ needs. This assembly line incorporates various features that improve productivity and product reliability, and uses a conveyor to advance the machines through the assembly process.
Inspection and Testing
While incorporating quality measures into every production process as a matter of course, for welded areas HCM ensures the best possible quality through double and triple checks and by conducting inspections using automated ultrasonic inspection devices. In the final stages of production, each and every machine is test-operated, and only those which pass this rigorous test procedure are sent on to the painting line.
Painting
The hydraulic excavators manufactured by this division (10-ton to 40-ton models) are painted by painting robots. Hard-to-see thin panels (covers and so on) and hard-to-get-at parts are coated by special cationic electodeposition to prevent corrosion.
Kasumigaura Works
The Kasumigaura Works processes and assembles numerous machine parts. Every stage of the plant's production, from materials provision to finishing, is computer-operated and -controlled. An FMS line enables unmanned machining of a wide range of components, and a rationalized stock management system featuring unmanned guided vehicles links various kinds of numerically controlled machine tools with an automated store room. The interweaving of these systems into a synergistic whole has enabled streamlined, fully integrated production processes and greatly improved labor-saving and efficiency.
To the Global Market
To improve our capacity to meet users' diversifying needs promptly, HCM maintains a company-wide information network and production system directly linked to information provided by customers themselves.
