Medium and large parts are no longer difficult to process, DONGS machine tools provide heavy cutting force
As the manufacturing industry rapidly moves towards high-end, customized, and complex parts, the processing problems of medium and large parts are gradually emerging. Shafts, flanges, and pipes weigh hundreds of kilograms or even tons, with high processing requirements, complex procedures, and heavy cutting loads, make many traditional machine tools daunting.
Faced with this common problem in the industry, Shandong DONGS CNC Equipment Co., Ltd. (DONGS CNC) took advantage of the situation and took "heavy cutting, strong rigidity, and high stability" as its core positioning to create a series of medium and large horizontal turning centers and vertical lathe solutions, successfully breaking the bottleneck of large-scale processing and bringing customers unprecedented production efficiency and quality assurance.
一、The "three mountains" of medium and large parts processing
The parts are heavy, long and complex, and traditional equipment is not able to bear the load
Large-sized shafts or flanges often exceed the processing stroke and load capacity of general-purpose lathes, and workpieces are prone to vibration, deformation, and insufficient rigidity during processing.
The spindle torque is tight during heavy cutting, and the tool life is short
Medium and large blanks usually require large cutting depth and strong feed. Conventional machine tool spindles are difficult to output stable torque, which easily causes tool jamming and tool jumping, and the efficiency is extremely low.
It is difficult to complete all processes in one clamping, and processing errors accumulate
During multiple transfers and joint operations of multiple devices, the clamping error and alignment accuracy will be continuously magnified, seriously affecting the final dimensional accuracy and coaxiality.
二、DONGS Solution: Everything starts with “cutting”
DONGS is well aware that the real processing of medium and large parts must be based on "cutting smoothly", guaranteed by "cutting steadily", and aimed at "cutting quickly". Based on this, the company focuses on building a series of medium and large CNC machine tools with heavy-duty cutting capabilities to meet the rigid demand for large-scale processing in many industries.
1. High rigidity integrated structure design
The machine bed is made of high-strength cast iron in one step, the guide rail structure is widened and thickened, and the layout is optimized through finite element analysis, so that the whole machine maintains excellent vibration resistance during heavy-load cutting.
2. High torque spindle system, stable and strong power output
The core spindle is equipped with a high-power servo motor and imported bearing components, which supports low-speed and high-torque output. It can still operate stably under high-load and high-feed scenarios, and is particularly suitable for rough turning processes of thick-walled flanges and solid shafts.
3. Supporting tailstock, tool rest and hydraulic clamp
For structures such as long shafts and heavy pipes, DONGS can be equipped with high-rigidity tailstock, heavy-duty follower rest and customized hydraulic chuck to achieve all-round support and automatic positioning, ensuring the stability and repeatability of the workpiece during processing.
4. Multi-process composite processing function integration
In addition to the turning spindle, it also supports power turrets and end tool modules, which can easily integrate turning, drilling, milling, tapping and other processes, and complete complex processes in one clamping, significantly improving processing efficiency.
三、Customer feedback
A heavy-duty machining company in Europe had frequent problems with large shaft parts skipping and severe surface vibration due to insufficient spindle torque and rigidity. After introducing the DONGS medium and large horizontal turning center, the equipment easily achieved heavy cutting with a single 12mm cutting depth with its strong cutting force and stable structure, improving machining efficiency by 45% and extending tool life by nearly double.
The customer commented: "In the past, we could only 'machine slowly' and did not dare to cut. Now we can do rough machining directly in one go. It is not only fast but also accurate. DONGS machine tools are truly capable of handling large parts.
四、Large-scale processing is not only about "big", but also about "stable" and "accurate"
Many people think that large parts processing is just about "making the machine bigger", but this is far from the case. The real challenge is:
How to prevent large-size workpieces from deforming during machining?
How to control thermal drift during long processing?
How to maintain processing stability under high torque output?
Every device of DONGS machine tools embodies "stable, accurate and strong" in the details: from the turret locking force, to the spindle cooling system, to the chip removal efficiency and electronic control logic, all aspects are optimized around heavy-load conditions, just to allow customers to "dare to heavy-cut, be able to heavy-cut, and cut well" at the processing site.
Medium and large parts are no longer synonymous with "high difficulty". As long as the equipment is selected correctly and the configuration is in place, heavy-duty cutting can still be efficient and accurate. DONGS has proved that CNC machine tools that can truly handle large workpieces must have strong core capabilities and a solid manufacturing foundation.
At a time when industrial manufacturing is accelerating towards high-quality development, DONGS's medium and large CNC equipment is becoming the key fulcrum for more and more customers to move towards efficient, intelligent and systematic manufacturing. Facing the future, DONGS will continue to take "heavy-load working condition solution expert" as its goal and continuously push the boundaries of "large-scale processing".
