The modular design of CNC lathe can simplify the production process, shorten the processing cycle and improve production efficiency. The rapid replacement of tools and workpieces can ensure a significant reduction in unit processing costs.
In EMOHANNOVER exhibition, CNC lathe supplier is a very important team, about 7%, accounting for about 12% of the exhibition area. In this EMOHANNOVER2007 exhibition, the participating team has not changed. German HALLEINEMCO Company is a branch of EMCOMAIERGMBH, Austria. From the point of view of Mr. DIETERKAUMANN, general manager of the company, "at present, the simplification of the production process is a hot topic of customer concern, that is, to concentrate all kinds of processes on one machine tool." This can further shorten the processing cycle in the customer's production process. Mr. KAUMANN said, "Our motto is 'Design for your benefit'. Processes that usually require several machine tools can now be completed by only one machine tool." In this regard, we can cite specific examples, such as the contour of the feed processing, deep hole drilling processing, cutting processing, hard material processing, process measurement or deburring processing.
In addition, another development trend is the increasing flexibility of production. For the batch processing of multi-size parts, the machine must be easy to clamp and debug, and can quickly adapt to the processing of other parts. Mr. KAUMANN said: "Our main goal is to minimize the downtime of the machine and improve the corresponding production efficiency." EMCO will present its main products at EMOHANNOVER2007 exhibition, from the newly developed high-performance machining center EMCOMECOF and MECMILL for general machinery production, to representative EMCOTURNE, MAXXTURN and HYPERTURN production lines, and to the newly developed CONCEPTTURN450 milling machine for training.
HUELLERHILLEGMBH is a division of MAG Industrial Automation Systems (MAGIAS), which received a batch of orders from Czech BONATRANS Group Corporation to manufacture two vertical CNC lathes for processing locomotive wheels. According to the plan, the delivery date of the machine tool should be in October 2007. In 2005, HUELLERHILLE had already delivered two similarly designed machine tools to BONATRANS, using an automated loading system. The VDM120RW type 4-axis vertical CNC lathe is equipped with a 165KW transmission system, which is converted into torque for the cutting of train wheels, and the cutting tool uses the corresponding gear, which can ensure that there are two tools on the wheel for cutting at the same time. In the pre-machining process, the maximum cutting depth can reach 12mm. The whole process is called sequential processing. The first and second clamping and debugging on the machine tool occurred one after another. In this step of processing, the turning of the wheel is automatically completed by the gantry tool loading system after the first clamping and debugging.
No work stoppage when replacing worn tools
The tools required for the two clamping and debugging processes are installed on a 4-sided rotary table. When replacing worn tools, there is no need to stop the machine because the machine is equipped with a magazine that can hold 24 tools. If necessary, the worn tool can be replaced with a new tool at the same time. During the peak period of processing, the tool in the tool magazine can also be manually loaded and unloaded by the machine tool operator.
When the new tool is installed, it is measured by the RENISHAW system and automatically corrected by the Siemens control system. All machines are equipped with a PROME-TEC interrupt control system to monitor the process. In the event of interrupted cutting or extreme tool wear, the tolerance limits of the feed power monitor are exceeded, which leads to an automatic shutdown of the feed device. Therefore, the tool can be automatically replaced in the process of picking.
FLEXTURN CNC lathe is a good example of efficient automated machine tools, the CNC lathe uses robot loading and unloading, by DR. -ing. Manufactured by ROBERTSTOPP Machine Tool Co. The CNC lathe provided by the company adopts a horizontal spindle, with a variety of designs and a small structure, which can load and unload the workpiece from the back, so it leaves a lot of space for the operator. For example, the modular structure of the machine tool includes a linear tool system, a tool rotation device, a pallet system, and additional dedicated processing units, which can be operated in a rapid cycle.
CNC CNC lathes with horizontal spindles have a variety of designs, suitable for the processing of various soft and hard materials. Manufacturers can provide various modules according to customer requirements. For example, the automation system module of the 100% control system and the special modules configured specifically for the customer's machining process. Included in the module are 4 types of headstock, 3 CNC axes of different sizes and each with a different stroke, a machine bed made of polymer concrete, automation by means of module processing and special solutions.
Considering the best processing scheme, vertical turning is the most ideal processing method for many materials. The CNC numerical control lathe provided by the company adopts vertical spindle, which is suitable for the processing of soft and hard materials. This machine tool can also be configured with corresponding automation modules according to customer requirements.
DZ45 CNC machine tool is a WEILERWERKZEUGMASCHINENGMBH series of products, its host has different models, cost-effective moderate, suitable for customer use. Its product range ranges from belt-driven 2-axis CNC lathes suitable for simple turning, to machine tools with tailstock and power tools, spindles with hollow shaft motors and machines suitable for omni-directional machining, and Y-axis configuration. All these machines are equipped with the proven Siemens 810/840D control system.
Optimal stability and dynamics during milling
The machine frame adopts a stable three-in-one structure. The bed supporting the machine is made of cast iron at 45 °. The machine is equipped with a hollow shaft motor, hydraulic device, control cabinet and liquid air cooling system. Compared with the previous models, the machine is equipped with strong and durable guide rods, has a wide guide gap, and increases the drive power of the spindle, so that it can guarantee the best stability and dynamics during the milling process.
Each spindle of the DZ45 machine tool is equipped with a safety clutch. The hydraulic tailstock and its new path measurement system are combined with the guide rod, which can move in the entire working area like the NC tailstock, and its driving force can be adjusted by programming. Its reverse axis can be used for comprehensive machining of complex workpieces. Like the spindle, its size is 42MM and the speed is 6000R/MIN.
The counter shaft has all the functions of an NC tailstock and can be used as a support or drill shank. The path measurement on the X-axis is carried out directly by the path measurement system. The quick switch tool rotating device can be installed with 12VDI30 tool station and or 16VDI25 tool station.
When asked what requirements a modern CNC lathe needs to meet, Mr. JOACHIMTOMASETTI, President of THHDREHTEILEGMBH, said: "For us, the concept of automated machine tools is the basis for equipment price competition. We need safety and continuity of processing. As a CNC lathe ordered by contract, it is also very important to meet the following conditions: simple operation, small footprint, fast clamping and debugging." Mr. THOMASSEEMANN, the ALLWEIERPRAEZISIONSTEILEGMBH's sales director, agrees with this statement. He said: "As a user, the reason for the priority and decision to purchase equipment is the processing time that can be shortened through the automation system."
