What has been the biggest concern for engine users?
Xichao Conway 4DW Five Long-term Oil Change Upgrade Products Are Coming Soon
For the user, the pros and cons of the engine are crucial. It is not only the decisive factor of the transportation efficiency, but also affects the transportation cost and economic efficiency.
As a veteran engine company, Xichai has started early oil change research and has led the industry in technical level. It has a strategic vision to transplant the Aowei captain oil change technology to the 4DW-E5 platform of light vehicles. In order to enhance the differentiated advantages of 4DW-E5 products, the 4DW-E5 long oil change model was formally developed to upgrade from the current user maintenance of 10,000 kilometers to the maintenance interval of 40,000 kilometers, and has been put into mass production through comprehensive testing.
Conway "core" upgrade fuel-efficient "star" model! Conway 4DW five-chang oil upgrade products will be on the market debut, which for many OEM partners, distributors and customers, is a major good news!
So, let us take a look at Conway 4DW's five long oil change products "core" upgrade manifested in what aspects?
First of all, there are three “more†upgrades for the 4DW long-term oil change structure: a better body structure, a stronger oil cooler and a larger oil pan. The three “more†improve the performance and reliability of the diesel engine by increasing the cooling capacity.
Second, 4DW's five long oil change filters and oil upgrades. High-efficiency oil filter significantly improves the filtration accuracy and capacity, improves the service life of the oil and the reliability of the diesel engine. At the same time, 4DW's five-long oil change heat test is factory-manufactured and filled with good oil, and the supply is based on the CJ-4 grade and The above engine oil has the characteristics of low ash and low pour point. It can take into account the low-temperature start-up, and the excellent oil performance significantly improves the performance index of the diesel engine.
Once again, 4DW's five long oil change cleanliness upgrades can effectively improve diesel engine production quality and product performance and reliability, mainly reflected in three aspects: First, Xichai's “lean production†concept has increased cleanliness Reliability provides the prerequisites for high reliability and high quality diesel engine production. Second, Xichai has perfect cleanliness standards. The cleanliness of many parts is higher than the industry standard. Third, Xichai has mature cleanliness. The system uses the cleanliness degree of Aowei's platform components to mature and improve the model. It quickly and effectively conducts cleanliness improvement work in the four dimensions of procurement, distribution, assembly, and market tracking. This is an inherent advantage that other engine companies do not have.
4DW's five long oil change products adopt high-pressure common rail system + intake throttle valve + EGR + DOC + DPF post-processing technology route, the technology is applied maturely, the supporting verification is sufficient, and the urea for refueling vehicles brought by the SCR route is avoided. The problem is that users use more peace of mind.
4DW’s five-long oil change product has been completely upgraded with a “coreâ€. It has inherited the captain’s oil change technology and ensured long oil change intervals. The normal maintenance cycle has been upgraded from the original 10,000 km to the present. The longest can reach 40,000 kilometers. In other words, for every 4 oil changes in the competing products, Xican only changed once, which saved 3 oil change times and drastically reduced the use of oil! Users not only improved attendance, but also saved maintenance costs. Conway 4DW five long oil change engine, every 40,000 kilometers can save money, filter, working hours, nearly 800 yuan! Save money is the user earned money! It is a money-saving tool!

Xichai Kangwei 4DW long oil change "core" upgrade, let Xichai once again walk in the forefront of the industry!
In general, computer numerical control milling machine (CNC) machining is a deductive manufacturing technique that programs 3-axis linkage, complex to 5-axis linkage, drives milling cutters to remove layers from solid blocks called blanks to produce finished parts. CNC milling is one of the main types of CNC Machining, which uses cutting tools that rotate at a speed of several thousand to tens of thousands of revolutions per minute (RPM) to precisely remove materials to obtain parts with complex surfaces. In addition to milling, CNC machining is also equipped with drills, boring tools, thread cutters and other tools to complete different part features at once. CNC machining produces parts based on a computer-aided design (CAD) model that is sent to a CNC machine through computer-aided manufacturing (CAM) software.
CNC Machining centers developed from CNC milling machines. The biggest difference compare to CNC milling machines is that the machining center has the ability to automatically exchange machining tools, by installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in a single clamping device to achieve a variety of machining functions.

CNC milling accuracy
CNC milling centers and high-Precision Machining centers. Ordinary machining center, resolution of 1μm, maximum feed speed of 15 ~ 25m / min, positioning accuracy of about 0μm. High-precision machining center, resolution of 0.1μm, maximum feed speed of 15 ~ 100m / min, positioning accuracy of about 2μm. Between 2 and 10 μm, with a ± 5 μm more, can be called precision grade. FCE equipped with different grade and different size CNC milling center. Take in to account into both economic and quality in parallel.
CNC Finishing surface treatment
Post-processing is the final step in the CNC machining process. In a quick guide, we offer a lot of surface treatments to complete your final parts and get them to meet strict specific requirements. It should be noted that in CNC machining, post-processing is in optional, as the quality of the machined parts is already very high.
Anodized
The anodizing process allows the part to obtain excellent corrosion resistance, increasing the hardness and wear resistance of the surface. Anodizing is also the most common pre-painting treatment, which can help the painted surface to obtain good adhesion. We typically apply two types of anodizing in our production: Type II, corrosion resistant; Type III is thicker, adding a layer of wear resistance. Both anodizing processes can achieve a variety of color effects.
Polishing
Grinding polish, it offers the fastest turnaround parts and does not require post-processing. The surface finish of the grinding part is equivalent to 125 um in Ra, and the requirements can be increased to 63, 32 or 16 um Ra. Minor tool marks may still be visible on the last part.
Powder coatings
Powder Coating is thermoplastic powder spraying directly on the processed part. The sprayed parts are then baked in an oven to form a durable, abrasion- and corrosion-resistant plastic coating. In the powder coating process, its color, brightness, surface roughness can be customized.
Shot blasting
Shot peening is the high-speed spraying of beads of different hardnesses and sizes onto the surface of the part. To get different textures and brightness of the surface. Since the surface has been hit by similar forging beads, the hardness and wear resistance of the surface have also been enhanced.
Design of CNC machining
CNC machining is a universal machining process, especially parts that can be cut and machined can be achieved through CNC, from simple shape shapes to complex curved structures. However, as with every manufacturing technique, CNC machining has some design limitations. We break them down as follows to ensure that your products are optimally designed to better fit the CNC machining process.
General Tolerance
When designing parts, the size of each part is different according to the application environment, working conditions, etc., and the requirements for the machining accuracy of the workpiece are also different. Although CNC machining can achieve very high machining accuracy, we should also be aware that demanding machining accuracy and accuracy (strict product tolerances) usually mean Longer production times and higher costs. If a specific tolerance is not specified in the product design, we recommend choosing at the following levels.

The highest precision of our equipment is 0.001, and the recommended most precise machining requirements do not exceed +/-0.005mm
Interior angle
All internal vertical edges of our products need to have rounded corners instead of right angles. This is because the tools used in CNC milling are cylindrical, which means they cannot produce inner right-angled edges. The fillet required by this process is called the inner corner fillet. When designing parts, the larger the inner corner fillet, the more efficient the production process. Because of the larger fillets, larger diameter milling cutters can be used to increase milling speed, and fewer swaps can be made to improve accuracy.
Undercut
Undercut cannot be machined with standard milling cutters, so the use of retract slots for parts should be avoided when designing CNC machined parts. In particular, for non-standard inner contour shapes, customized machining tools are required, which will greatly increase processing time and costs. Secondly, if undercut can not be avoided, due to the limited length of cnc tools, the undercut can not be too deep. If they are too deep or the location is difficult to reach, they will not be able to be produced because the CNC tool cannot reach the machining location.
Chamber wall thickness
CNC machining requires your part design to meet minimum wall thickness requirements. In general, it is recommended to choose the thickest possible and avoid very thin or characteristic walls. This is because CNC tools processing thin-walled parts will cause vibration deformation, which may cause interruptions or damage, and the size is out of specification. The standard minimum wall thickness for CNC machined metals is 0.030" (0.76 mm) and for plastics is 0.060" (1.5 mm).
Thread
When designing parts, it is useful to choose the largest possible thread size because smaller taps have a higher risk of breaking during production. If possible, avoid using deep hole threads as they lead to higher production costs, especially when custom tools are required.
Metal
In principle, materials with high hardness are easier to process because better processing accuracy can be obtained, but they are limited by the hardness of processing tools, so the hardness of the generally recommended parts is 8 ~ 60HRC, and for metal materials, the hardness is greater than stainless steel Followed by cast iron, followed by copper, and finally aluminum, while the processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. Fast production time.
Polymer
Although CNC can process thermoplastics, the material properties of polymers still have many difficulties for CNC processing. First, due to poor thermal conductivity, many thermoplastics melt or bend when in contact with CNC milling machines or drill bits. Secondly, the processing of plastics, because the hardness is low, the size accuracy caused by the knife during product clamping and processing is not high. For those parts that do not have special requirements for the strength and hardness of the metal, thermoplastics can provide a cheaper alternative.
Cost optimization of machined products
Simplify product design
Simplifying product design while taking into account functionality usually saves production time and reduces production costs. Because the manufacture of complex structures and surfaces often requires complex longer passes, more layering to obtain the same fine contour quality. This means higher production costs.
Reduce cutter changes
Using the same milling machine machining features, larger and same internal fillets, can reduce the number of tools used to reduce machining time. For example, if a workpiece needs a 10mm end face milling cutter to process some features, it also needs a spherical milling cutter to process a curved surface, and a 2mm milling cutter to process a fine groove, which will require repeated tool changes and reduce the machining efficiency
Proper material selection
The choice of raw material for machining can have a significant impact on production time and costs for CNC machining. If possible, choose a material with good processability, such as brass or aluminum. For those applications that do not require metal hardness and strength, CNC machining of engineering plastics like PMMA and ABS also helps to reduce costs because the material blank is cheaper, and the processing efficiency is higher.
Tolerance and wall thickness
Higher tolerances and thinner wall thicknesses also increase THE CORRESPONDING CNC machining costs, as it takes time to achieve higher precision cutting. If your product or component can accept a larger size range, choose a lower tolerance to reduce production time and costs. The same is true for wall thickness: a larger wall thickness margin should be chosen.
Choice of surface treatment
Surface treatment is often the final stage of the CNC machining process, which can also affect the cost of your entire project. Choosing less surface treatment for your part or product can lead to better time and cost efficiency. FCE can recommend to you how to optimize the surface treatment to balance the conflict between cost and quality according to your final needs.
