Beneficial Modularity
Modular systems have succeeded in finding their way into the lives of many people, from LEGO construction toys to IKEA’s modular furniture.
Article by ISCAR.
In metalworking, typical examples of these systems are unit-built machines and modular fixtures. As for cutting tools, modular structures have proven their efficiency in this area as well, and various tool manufacturers have developed their own modular products that are popular with their customers. The main benefits of modularity are versatility and time savings. A modular concept facilitates the quick and easy building of an optimally customized cutting tool using an assembly of standardized elements. Hence, customers don’t have to order a costly, specialised tool and wait months for delivery. If a tool is urgently needed for immediate production, a suitable solution is close at hand.
This concept contributes to reducing warehouse stock and diminishing inventory lists that cut manufacturing costs. However, the modular tool concept is not free of disadvantages. The main disadvantage is the decrease of rigidity; an assembly of several elements is not as stiff as an integral product and the assembled structure may lose accuracy when compared to a one-piece design. When deciding on a particular tool, both advantages and disadvantages of the modular concept need to be considered. The customer is the only one that can decide which is the best tool for his needs based on production strategy, current production demands, or an immediate need for a tool. The cutting tool manufacturer should provide the customer with the means to make the correct choice and at the same time continue to develop modular products that achieve greater adaptability, rigidity, and accuracy.
A glance at ISCAR’s modular cutting tools makes it possible to showcase the design features of a product.

On High RPM
Andrei Petrilin, Technical Manager of ISCAR discusses the importance of high-speed spindle and the requirements in high-speed machining (HSM).
High-speed machining (HSM) has not only led to a significant difference between machine tools but has also brought awareness to the high-speed spindle; perhaps, the most important and central component of high-speed machine tools and a key factor for the success of HSM.
High Speed Machining
Operating a spindle with high rotation speed and gaining the optimal balance between the provided speed and torque is the main task of high spindle engineering. The spindle’s performance depends on several different factors. One of the main factors relates to the design concept of a single- or combined twin-motor bearing system, seal components, and a tool retention method.
When machining, the spindle is not in direct contact with the workpiece but interacts with it through another technological system – the cutting tool. This connection acts as a conductor and should transform the impressive capabilities of a high-speed spindle into improved machining results. Another element between the cutting tool and the spindle is the toolholder which is fitted into the spindle. The poor performance of this small assembly, the cutting tool and toolholder, may reduce the function of the spindle to zero. Therefore, HSM toughens the accuracy, reliability, and safety requirements for the assembly of the spindle extension.
High-speed rotation generates centrifugal forces. In HSM, when compared with traditional machining methods, these forces grow exponentially and turn into a significant load on a cutting tool which determines the tool’s durability. In indexable milling, high centrifugal forces may cause insert clamping screws to break, inserts to loosen and a cutter body to fail. Formed fragments can not only damage a machine and a machined part but can be very dangerous to the operator.
In such conditions, cutting tool manufacturers are compelled to consider the design and technological means necessary to ensure appropriate reliability of their products. Hence, the focus on indexable milling cutters should consider secure insert mounting and a robust body structure.
Reliable Milling
Let us start with a clamping screw, the smallest and weakest element of a whole technological system with a great impact on the system’s reliability. The same can be said about the clamping screw in relation to a high-speed indexable milling cutter. Applying dynamometric keys controls the tightening of the clamping screw. (Fig. 1). However, ensuring the torque is tightened sufficiently is not enough to reliably operate the cutter. Intelligent design is directed to minimise the dynamic load on the clamping screw.
