Suzhou Lunqiu Mechanical Equipment obtained a patent for drilling and processing equipment for automobile parts, reducing stress damage to components
Are you also in a state of hesitation, should you spend hundreds of thousands or even millions to purchase a large-scale parts processing equipment? If you buy it back, you will worry that the order quantity is not enough; if you don't buy it, you will worry that you will miss this rare opportunity.
For small and medium-sized machining factories in Suzhou and the Yangtze River Delta region, competition has become fierce in 2026. The requirements put forward by customers are fast delivery and stable quality, but the price conditions are still lower. In such an environment, every equipment investment must be carefully calculated. A patent recently announced by the State Intellectual Property Office accurately meets this pain point. This patent, called "a drilling and processing equipment for automobile parts," was filed in April 2025. It originated from a technology promotion service company in Suzhou that had been established for nearly ten years. Its design ideas may help you figure out an investment account.
Three hidden costs of traditional drilling equipment
Many smaller shops still use older drill presses today to machine automotive parts. For this particular type of equipment, the impact of the rig's downward motion during drilling operations is considerable. After being put into continuous use for a long time, the probability of fatigue and deformation of the screw and guide components is relatively high. According to feedback from a processing plant in Nantong, Jiangsu on investment in large-scale parts processing equipment , an older piece of equipment they owned had to replace the screw rod every six months; and every time maintenance work was carried out, the equipment had to stop running for two days, which directly resulted in a total order loss of nearly 10,000 yuan.
What's even more troublesome is that this impact will have an impact on drilling accuracy. When the drill bit is in contact with the surface of the workpiece, if the force control is not good, it can easily cause the hole position to shift or the exit to produce burrs. For automotive parts that require higher precision, such as engine mounts or suspension components, this means an increase in scrap rates. There is a parts factory in Taizhou, Zhejiang. Its data shows that when using traditional equipment to process certain types of parts, the scrap rate was once as high as 5%.
The maintenance cost of traditional equipment is difficult to estimate. Once the core components are damaged, the repair cost is high, and parts may need to be waited for. For processing plants, equipment shutdown means money is lost. These invisible costs often far exceed the money saved when buying the equipment.
What are the technical highlights of the new patent?
Modifying the structure is a unique operation performed on this newly released patented device. It abandons the cumbersome hydraulic and pneumatic systems and uses a set of positive and negative screw holders to control the drilling rig's downward movement. Specifically speaking , when the screw rod rotates, the two slide blocks above will drive the wedge block to move toward the middle. This wedge-shaped rotating block will push the wedge-shaped seat on the lifting base, thereby allowing the drilling rig to descend smoothly.
The whole process is a purely mechanical linkage state. How exactly are they linked? It is the lifting motor that drives the screw rod, which in turn drives the holder, and the holder then pushes the drilling rig. What are the benefits of this design? The advantage is that the downward pressure is applied gradually when drilling, not as a sudden impact. What exactly happens when a drill comes into contact with the surface of a car part? The force will be more even and the impact will be smaller.
In addition, a return spring and a first guide column are also designed on the device. When drilling is completed, the spring can help the drilling rig return quickly to prepare for the next operation. This structure is simple and reliable. Compared with equipment that relies on sensors and hydraulic systems, it has fewer failure points and is more convenient for maintenance.
Practical benefits to small and medium-sized processing plants
The most direct benefit of using this device is to reduce the frequency of maintenance. Because the downward impact of the drilling rig is dispersed by the slope of the wedge block, the instantaneous stress on the screw and guide components is greatly reduced. For a shop that drills hundreds or thousands of holes every day, this means savings on repairs several times a year.
The second benefit is to improve the processing accuracy. The drilling rig moves down smoothly and it is less likely for the drill bit to "gnaw" the workpiece. This is extremely critical for processing automobile parts that require a hole diameter accuracy within plus or minus two wires. As the accuracy is improved, the scrap rate can be reduced. According to a factory in Suzhou, it is estimated that for every one percentage point reduction in the scrap rate, an additional five to six thousand yuan can be earned per month.
The third benefit is that the equipment has a longer life, its mechanical structure is simple, and it suffers less stress damage. In this way, the entire equipment can be used for seven or eight years without problems. For small factories that do not have sufficient funds, this kind of durability means that they can benefit from it for a long time after a single investment. They do not need to frequently consider the replacement of equipment . Investment in large parts processing equipment can then be used where there is greater need.
Several things you need to settle before investing
The first account is the purchase cost. The structure of patented equipment is more reasonable. However, because it is a new technology, the initial price may be slightly more expensive than that of an old-fashioned drilling machine. You need to compare the savings it brings with the additional purchase price to see how long it will take to pay back the cost. Under normal circumstances, if you can earn back the price difference within two years by saving maintenance costs and reducing the scrap rate, it is worth considering.
The second account is the cost of use. For this type of purely mechanical equipment, daily maintenance mainly involves adding lubricating oil and checking the wear of the wedge. Compared with hydraulic equipment that requires regular oil replacement and filter cleaning, the maintenance cost is lower. You can consult the manufacturer to know the replacement cycle and price of wearing parts.
The third account is related to personnel training. Is the operation of the new facilities and tools complicated? How long does it take for employees to become familiar with it? Judging from the description of the patent, its operating logic is significantly different from that of ordinary drilling machines. The key point is that it mainly relies on the motor to control and drive the screw rod according to the given rules and regulations. As long as workers receive a little more basic training and training at the corresponding stage and period, they should be able to start and join it smoothly. But if you have to hire technicians specifically to carry out programming work, then you have to calculate the cost of labor income of the people involved in such an action.
Looking at technical reliability based on corporate background
This company, established in Suzhou in 2017, is the applicant for this registered patent with a capital of 1 million yuan. It can be seen from public information that the company is mainly committed to technology promotion and application services, and already has 3 patent information. This means that it continues to invest in research and development and accumulate technology.
April 2025 is the starting time for application, and one year has passed by April 2026. During this period, the technology has most likely undergone actual testing or small-scale application. The fact that a company can obtain an authorization notice indicates that the examiner of the patent office has determined that its structure is novel and practical.
For processing plants engaged in purchasing equipment, a reliable source of technology is very important. This company has its roots in Suzhou, which happens to be surrounded by the auto parts industry gathering area. Its own design is most likely based on the actual pain points of local factories, and is not in a closed-door state. This kind of technology that is closely related to the production line is usually more realistic and has fewer problems.
Which factories are best to consider
One of them, Suzhou Lunqiu Machinery Equipment, has obtained a patent for drilling processing equipment for automobile parts, which reduces the stress damage of components. It is an outsourced processing factory that specializes in the process of drilling metal parts for automobiles. Secondly, such factories generally have stable order volumes, but they are quite sensitive to prices. Third, hundreds or even thousands of parts must be processed every day. The efficiency and quality of the drilling process directly determines profits. Fourth, the use of this kind of impact-reducing equipment can significantly reduce the scrap rate and downtime.
The factory produces precision parts, such as turbine shells and valve bodies. The processing of products such as turbine shells and valve bodies requires deep holes or high-precision holes. Traditional equipment is prone to produce burrs at the hole exit, which requires secondary processing. This drilling method can smoothly drill down, effectively reduce burrs, and even eliminate a deburring process.
It is the kind of small and micro enterprise that has tight space and tight funds. This equipment is compact and requires no additional hydraulic station or air pump. It can be used when connected to the power supply and occupies a small space. For those owners who rent a small workshop in an industrial park, this is a very real advantage.
After looking at such a complicated situation, do you think it is worthwhile for a small processing factory with only five or six workers to spend hundreds of thousands to replace this new type of drilling equipment?
