Machine Tool Adapter Clamping Unit Improves Turning Center Utilization
The issue of long downtime for tool change in turning centers has continued to this day. From the 1960s onwards, labor-intensive manual tool change was no longer used in machining centers. Today's machining center's tool change time is only a few seconds.
The tool change time has a direct influence on the utilization of the machine tool. For all machine tools, tool change means downtime rather than production. The potential for improving production competitiveness and return on investment by shortening tool change time is still underutilized.
Most of today's turning centers are equipped with power turrets for rotating tools, and the tool change time is directly related to the production efficiency.
Fast tool change is of great benefit for all types of cutting, and machine tools with high cost are particularly noticeable at the time. If you can reduce the downtime of each tool change by a few minutes, or even stop it at all, you can add a lot of extra capacity every year.
Turning centers are often used in high-end industries to process high-tech parts in small batches, often at very high cost.
For complex parts that require more cutting steps, it is necessary to frequently replace various types of tools.
High-tech/high-volume production is very sensitive to machine downtime, and the standstill costs of production are extremely high (for example, the production of certain parts for the automotive and hydraulic industries).
Today's turning center turrets have blade adapter interface options. The interface is typically a VDI or square shank, but nowadays it is difficult to meet the need for quick tool change.
A new solution to the problem of effectively dealing with the long downtime common in many typical turning centers is to use a machine tool to adapt the clamping unit based on the concept of the Coromant Capto interface. This kind of interface application has become more and more extensive, becoming the standard or optional interface configuration of many machine tools.
Adaptation clamping unit. These clamping units are suitable for a variety of models currently on the market or being used by users, have a variety of different coupling interfaces and form factors, which make them can be easily matched with the turret, and hold various turning and rotation Tool. This makes it easier to optimize the turret in the turning center to improve cutting performance and stability, and the most important thing is to increase more effective cutting time.
The machine-adapted clamping unit for quick tool changes has a number of efficiency-enhancing features.
These safety and efficiency concerns include: high accuracy of the cutting edge, elimination of most of the measured cutting processes, reduced tool nose projection length to reduce the risk of interference, presetting ideal coolant injection direction and tool management Wait. The interface between the tool and turret (machine interface) itself also provides additional benefits for machining, such as increased stability, strength, and repeatability. The use of four bolted clamps provides good stability, but the tool change time is slightly longer than the VDI interface. However, when CoromantCapto is used for rapid tool change, it can enjoy the ideal stability and tool changeover effect at the same time.
For most European brand turning centers, the Coromant Capto Disc Interface (CDI interface) can replace the existing VDI interface. The CDI interface uses large diameter mounting holes to match the turret, which is very suitable for the power tool holder, because the drive bearing and broach mechanism inside the tool holder can be placed inside the turret, which can also shorten the protruding turret part of the tool holder. length. Regardless of the brand and model of the machine, the same clamping unit can be used uniformly throughout the entire shop.
The Coromant Capto Bolt-on Interface (CBI interface) is tailor-made for different types of turrets in Asian brand turning centers (different machine tool manufacturers like to use their own bolted form). As to whether or not the power head holder is used, it depends on the spatial structure and whether these units can be placed inside the turret.
When the need to replace a different turning tool due to a change in a production part or to replace a worn rotating tool, the benefit of using a tool quick change in the turning center is particularly significant.
The full range of cutting tools with Coromant Capto or clamped inserts embodies the latest indexable insert and cutting tool technology for efficient and stable machining. Examples include vibration-damped Silent Tools, extended CoroTurn SL systems for tool modular applications, and Turbo Bar compound tool concepts.
to sum up
In the new machine tool investment, the concept of "correct start, half of success" can produce the best results: that is to say, use the right tool at the beginning of processing. In the planning phase of the purchase of the turning center, it was determined that the turret's machine tool clamping unit reflected this concept. These clamping units can also be integrated into the turning centers currently in use on the shop floor, which will bring additional capacity potential. The facts show that any additional investment made to improve tool change can achieve faster overall returns through increased machine utilization.
