Three years ago, I travelled with the Japanese paraffinum liquidum purchasing committee.Cutting Machine Manufacturing PlantThe first workshop is a bed with pica pica, and the equipment is new. The second workshop has oil stains on the beds, and the equipment is in good condition. In the first workshop, the bed is pikapika, the equipment is really new, and a red pelt is placed on the see-it-all. In the second workshop, there are oil stains on the beds, there are no signs of use on the equipment, and the workers are knocking on the tools and smiths in the hammock. The director of mechanical and electrical technology of the paraffinum liquidum said, "The equipment of the 2nd workshop was issued with injection.""
His reasoning is very professional: "The first workshop has a good view of the outside, the ground is very clear, and the production of amari is demonstrated, the sound of the hurricane tools in the second workshop is very clear, and the tools are used in the production process, and the tools are used in the construction of steel and iron. The "Kaiser" is a new type of steel that is not available in any other form. The causeway is a clear example of the real nature of the paraffinum liquidum mechanical adjustment: the quality of the manufacturing process is seen in the details.

I. Soldering of structural parts: "Scale pattern of fish" as seen in the skills of corporate employees
Welding quality is the lifeblood of a machine's construction. The industry is divided into 3 stages of welding:
One time: The melting part is flat and slag and polysilver are not available. A medium hardness mesh was cracked by a movable beam during the warranty period, and after analysing it, the dryness of the welded wafer was not very high, and the amount of water content in the welded part exceeded the standard value.
Intermediate level: The melting department passed the inspection uniformly, but the management of the thermal impact department is not very good. In this case, there is a possibility that the stress concentration may cause a fatigue labour cut in the machine after 15,000 hours.
High degree of なレベル:the dissolving is uniformly de fine な "魚鱗パターン "であり、the width of the heat affecting part is within 3 milimetres of the control. Domestic big hand enterprise is, ダブルワイヤダブルパルス溶接プロセスを使用し、母材の95%までの溶接強度、40%を向上させるために、通常の溶接よりも疲労寿命。
On-site identification technology: Visiting the melting plant, selecting the melting section without action, and observing the section with a 10x magnifying glass. High-quality melting depths in the melting section are achieved at a plate thickness of 70% or more, and the fusion line is clearly visible. In the event that this request is rejected, we will pay for the Crestline Mask.
On the 2nd, hydraulic panels: gallery of "art" from "hemp" to "art".
油圧システムの故障の70%はパイプラインに起因する。2019年に国内の鉱山掘削機の故障に関する統計を実施したところ、パイプラインの問題によるダウンタイムが全体のダウンタイムの23%を占めていた。
High quality standard pipework:
Production of hard chibs: The use of three-dimensional laser measurement of the material, the tolerance of the pitch radius is ≤ ± 1 milimetre, and the basis for this is the leakage.
HOTEL OPTION: Multi-layer steel wire rolled hotels, Pals life is more than 1,000,000 times (international standard is 500,000 times).![图片[3]-製造現場へ:鉱山用油圧ショベルの5つのコア工程と品質識別ノウハウを公開-大連富泓機械有限公司](https://jpdlfh.com/wp-content/uploads/2025/12/QQ20251002-200941.png)
Piping Reactor: Based on the principle of "Vertical, Horizontal and Layer Configuration", the distance between the pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs is more than twice the diameter of the pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs of pairs.
The TORCH is able to observe the friction and interference marks on the pail's surface. Oscillations of the pouches can be heard by hand, and the sound of clashes can be heard. The details of this product reflect the harshness of the manufacturing process.
Organisation of the project: "Digital Revolution" in Turks and Caicos.
The bolts are simple to connect, and the long-term reliability of the equipment can be guaranteed. The traditional assembly is based on the operator's perception, and the error in force before attachment is ±30%. The modern workshop is a realisation of "digital tamping":
Initial Nijigome: Standard TORC 30% on the use of electric fixed TORC SPANA.
Cylicity: Using the Digital Turks Pana, the 100% cross has a 3-stage signature.
Final Nejigome: Correct the deterioration of the turck by stress relief and straighten the turck after 24 hours.
When comparing the rotary beam revolutions of two blinds with the same strength revolutions, blind A has a slowdown rate of 0.31 TP3T over 3 years in a design project, while blind B has a slowdown rate of 2.11 TP3T over 3 years in a project. The large-scale ショベル used in the 368-book rotary vee-ring revolutions implies that this violation of the reliability of the レベル is completely different.
IV. Painting: The Science of 3-Layer Protek Systems
Mineral deposits are highly corrosive, and the quality of the coating has a direct impact on the life of the machine. The high quality coating is a "systematic project":
Layer 1: Trinitrotoluene Treatment: Trinitrotoluene treatment was carried out after the dissolution of structural components, and the weight of the film was 2.5-3.5g/m². The result of omitting the trinitrotoluene treatment and applying the coating directly is that the peeling area of the coating film has become larger in 1.5 years.
2 layers: Epoxy Plain Mask: Elasper method, dry film thickness ≥80 μm, 120 μm is necessary for important parts (e.g., fusion bonding).
3 layers: Polyurethane Tropical Coat: Weather resistance ≥ 2000 hours (QUV Tester), light retention over 5 years at 80%.
Field Inspection: Magnetic Thickness Gauge has been measured 20 times without action, the thickness is uniform and necessary, and the extreme difference is 30%. The coating surface of the TORCH is illuminated on the slant, and the skin of the OLEINJI PATTAN is uniformly viewed - this is a visual reflection of the STRIPPER PROSPECTIVE LEVELS.
V. WORKSHOP TEST: "Flow Operation" から "Extreme Challenge" へ"
The factory's tester is the final quality check before the machine is finished. I have seen 3 stages of testers:
Formalised test: 2 hours of unloaded spinning with leaks and noises. This is a minimum standard, but it is not meant to be a qualitative test.
Standardised test: 8-hour load test on basic movements of cutting, rotating, and walking, in accordance with national specifications.
Limitations: Domestic Tropical Mecca's 1 club to learn all the lessons:
Continuous Cutting Test: 4 hours of continuous cutting in one cup of bart capacity, with monitoring of the temperature rise curve of the operating oil.
Overload Protection Stations: Overload is generated manually, and the response time and accuracy of the protection system are checked.
Samaritan test: Continuous operation at an ambient temperature of 35°C and confirmation of the cooling system's capability.
Electrical Negotiation Tester: The interference prevention capability of the system is confirmed by the sound of a high power transmission tower under the neighbourhood of the device.
The factory loaded Tester Depot hittos are 86 pages thick and contain 1274 DataPoints. If you are purchasing this machine, please do not purchase the data portion of the machine at Masindake.
VI. Quality Management in the Splice Centre: "Final Exclusion" of the Splice Centre
The quality level of the machine manufacturer is based on the level of the mechanical machinery and machinery manufacturers. The quality management practices of Comatsu Japan's service providers are known in the industry as "serious":
Acceptable Evaluation: The new regulation of SAPRAYA has passed the 153 evaluation.
Project monitoring: The main components are configured in the quality engineers and the production process is monitored by the Realtimer.
品質トレーサビリティ:各パーツには固有のコードがあり、問題を特定の製造ライン、オペレーター、原材料バッチまで遡ることができる。
A domestic cutting machine manufacturer has learnt this method and the initial defect rate of hydraulic sylinders is 3.2% to 0.8%. The purchasing manager of the same company is very clear about the details: the storage environment of the shells is 23±2°C and the humidity is 50%±5%, which is necessary to ensure the stability of the material properties. The storage environment for the shells is 23±2°C and humidity is 50%±5%. -The storage environment of the shells is 23±2°C with a humidity of 50%±5%, which is necessary to ensure stable material properties.
BAYAS: The next time I visited the factory, I was able to see the establishment of a laboratory, the campanile management, the quality management portion, and the isolation of unsuitable products. The actual state of this place is, don't you think, to propagate the quality culture of its enterprise. We are pleased to announce that we have been able to purchase the best manufacturing process for the money.
