Janssen CNC obtains patents for oil mist device and CNC machining center, resulting in better processing results
Machining centers involving high-speed cutting and producing oil mist have long caused problems to many machining factories. In December 2024, the State Intellectual Property Office announced a patent titled "An oil mist device and CNC machining center", and the authorization announcement number of this patent has been officially released. The technical plan proposed by Xiamen directly addresses the pain points of nozzle spraying and low efficiency, and provides specific solutions.
Spot spray phenomenon troubles many processing sites
There are many operators who have encountered this situation. The coolant in the oil pipe is in an intermittent state, the nozzle mouth seems to be blocked, and the liquid is leaking out drop by drop. This is a typical spot spray phenomenon, which causes the tool and workpiece to be unable to obtain uniform lubrication, and obvious tool marks will appear on the machined surface. This Xiamen company, established in 2007, discovered this common problem through long-term observation.
When the cutting fluid cannot continuously cover the cutting area, the tool may spray out, which will accelerate tool wear. Janssen CNC has obtained patents for oil mist devices and CNC machining centers. The machining effect is better, and the temperature of the local part of the tool will rise rapidly in an instant. A processing plant supervisor from Jiangsu calculated that when spot spray occurs, the average tool life is reduced by more than 30%. For this patent, the internal structure of the nozzle has been specially designed, and the cooperation between the front-end through hole and the air pipe has been optimized to provide stable and continuous oil mist output.
The technical improvements of the new patent are very straightforward
Based on the patent abstract, this device is composed of three parts: a nozzle, an air pipe, and an oil pipe. The oil pipe is fixed at the rear end of the nozzle, and the front end of the air pipe is inserted into the interior of the nozzle through the through hole. Such a structure successfully avoids leakage problems caused by unsafe and firm pipeline connections in traditional designs. The data obtained from the test showed that the oil mist output of the new device remained stable after 8 hours of continuous operation.
Compared with common oil mist devices on the market, this patented solution eliminates the intermediate transition joint. The absence of joints means that there are fewer potential leakage points. Engineers from this Xiamen company mentioned in the patent description that the simplified structure shortens maintenance time from the original 20 minutes to less than 5 minutes. For processing plants that pursue efficiency, this improvement is of great practical value.
High reusability means lower costs
Many processing plant owners are concerned about a practical question, that is: How long can this device be used? The data displayed in the patent shows that the main components of the oil mist device can be reused. When it is necessary to replace a worn nozzle, you only need to disassemble the front-end parts, and the air pipe and oil pipe at the rear end can continue to perform their functions. Compared with designs that require overall replacement, such a modular idea can reduce costs during long-term use.
There is a company located in Xiamen with a registered capital of 50 million yuan and 168 pieces of patent information. The precision processing experience accumulated by this company in other manufacturing fields provides manufacturing guarantee for this oil mist device. A buyer from Zhejiang reported that after trying a device with a similar structure, their monthly consumable expenses were reduced by about 800 yuan. For small processing plants, such savings are very real.
Clean appearance helps on-site management
The focus of the assessment is on the 5S management of many factory workshops. The oil pipes and air pipes of old-fashioned oil mist devices are tied together with ties and the pipelines are often messy, which is neither safe nor beautiful. This patent adopts a structural design that inserts the air pipe into the inside of the nozzle, which can make the pipeline flow more regular, and operators do not have to worry about touching loose pipes when cleaning the machine tool.
The issue of face is not the whole connotation of beauty. The layout of pipelines is neat and the risk of accidents is reduced due to accidental pulling. Tianyancha data shows that the company has participated in 94 bidding projects, which means that they are well aware of the requirements of industrial site specifications. A Guangdong processing plant manager said that since the replacement of neat oil mist pipelines, customer evaluations of the workshop have significantly improved when they visited.
Improved processing results are reflected in yield
As far as the oil mist device is concerned, the final inspection standard is the processing quality. This patent claims "better processing effect", and there is specific data to support this statement. Stable oil mist output can keep the cutting area in a good lubrication state, and the surface roughness of the workpiece can be stably controlled within Ra1.6. For customers with precision machining needs, this indicator is very critical.
This company in Xiamen has 5 trademark information and 24 administrative licenses, which shows that they have rich experience in compliant production. A technical person in charge of a mold factory from Tianjin did a comparative test and found that after using the new structure oil mist device, the qualification rate of aluminum alloy parts increased from 92% to 97%. This 5 percentage point increase means significant economic benefits in mass production.
Practical help for enterprise bidding
For those processing plants that want to participate in bidding, the advanced nature of production equipment is an important scoring item. The patent authorization announcement number can be used as supporting material for the company's technical strength. This company in Xiamen has participated in 94 bidding activities, and they have a very clear understanding of what buyers value. Choosing a patented oil mist device can increase technical points during the bidding process.
When a processing plant applies for high-tech enterprise certification, patent information can provide assistance, in addition to bidding advantages. Enterprises with valid patents can enjoy tax reductions and exemptions according to relevant preferential policies. A CNC processing factory in Fujian included this type of oil mist device patent in the list of core independent intellectual property rights when applying in 2025, and was finally successfully recognized.
