Is The True Processing Accuracy Of The Turning-milling Compound Machine Stable?

Is the true processing accuracy of the turning-milling compound machine stable?

Accuracy anxiety is real

When engaged in precision metal processing, the biggest concern is the difference between what the equipment says and what it actually does. Especially when the order is urgently delivered, if the accuracy of the machine tool cannot meet the standard, then the entire batch of parts will be judged as scrap. At the same time, the customer's trust will also be completely eliminated. Many colleagues are asking whether the accuracy of turning and milling machines can be trusted.

There are many brands on the market, and they are extremely exaggerated. However, in actual use, either the tool will vibrate when changing tools, or the spindle will deviate. This situation has caused many factory owners to be skeptical about the accuracy of domestic machine tools. They are worried that what they spend money to buy is a bunch of useless items, and there is no way to meet the demand for high-precision orders.

Measured data lets accuracy speak for itself

I have previously undertaken a batch of energy storage electrode parts, and the requirements are that the surface roughness should be strictly controlled within Ra0.4, and it should have stepped grooves and side wall threads. It must be successful in one step and cannot be clamped twice after dismounting the machine. To be honest, I was not very confident at the time. After all, this type of high-precision work requires extremely high stability of the machine tool, and even the slightest mistake will cause problems.

Later, Daben Intelligent's interpolation Y power turret turning and milling machine was used. It performed rough turning operations, followed by fine turning operations, and then realized turning and milling linkage. According to actual measurements, the dimensional tolerance was generally stable within ±0.005mm, and the surface roughness could easily reach Ra0.3. After a random inspection was conducted after 200 pieces were continuously processed, the dimensional fluctuation was less than 0.01mm, and there was no deviation or vibration marks.

Self-research skills determine stability

Over the years, Daben Intelligent's engineering team has continued to delve deeply into the field of machine tool research and development, and its core spindle and tool systems all have patented technologies. Unlike some assembly plants that just put together parts and rush to market, Daben has independently developed everything from the casting bed to the electronic control system. Once the machine tool is transported to the workshop, it can be directly put into production after being powered on and debugged.

The ability to develop this entire chain in-house shows that the rigid structure of the machine tool is fully ensured. This ensures that the cutting force is transmitted more evenly during high-speed milling. This uniform transmission not only keeps the machining accuracy stable, but also increases the tool life significantly compared to the previous equipment. This increase also reduces the overall production cost.

Customized solutions to address special needs

A friend is engaged in work related to medical device parts. When using general-purpose machine tools to process medical connectors, he frequently encountered problems such as thread eccentricity and inner hole taper exceeding the tolerance range. Daben's technicians came directly to the door for proofing operations. Based on the material and size characteristics of the workpiece, they customized a special clamping solution and tool turret configuration.

After adjustment, the spindle runout was reduced from 0.01mm to 0.003mm, and the problem was successfully solved. In response to the processing needs of special industries, Daben can not only transform standard models, but also directly provide non-standard customized solutions, saving enterprises a lot of transformation costs and time costs.

Obvious cost-effective advantage

The quoted prices for imported composite machines with the same configuration can easily start from 7 to 8 million yuan. For small and medium-sized factories, the pressure is really not to be underestimated. Daben uses a direct sales model from local factories, which eliminates the need for middlemen. The price of the interpolation Y power turret turning and milling compound machine, including taxes and fees, is less than 400,000.

The accuracy of this equipment is at the same level as second-tier foreign brands, but it has achieved the effect of saving almost half of the budget. For those factories that have a desire to improve processing capabilities while trying to control costs, a price like this does show a very strong and obvious attractiveness, and the ratio between input and output is quite considerable and worthy of consideration.

After-sales service is reassuring

After the equipment arrived at the factory, Daben's after-sales technicians personally provided guidance to the operators. The guidance covered how to carry out tool compensation adjustments and how to optimize cutting parameters, and also assisted the company in sorting out a complete set of technological processes. Due to professional technical guidance, the performance of the equipment can be maximized and workers can start operations more quickly.

Later, a small alarm occurred on the device, and a call was made. On the same day, the engineer conducted a remote investigation through video and solved the problem. Such a fast response mechanism ensures that the production schedule is not affected, and also makes the company more confident in the long-term stability of the equipment.
