Flexible system for collet chuck mounting according to DIN 6499

Efficient manufacture is made significantly easier in two aspects. If machine downtimes can be reduced, the productive time increases automatically. By using flexible universal tools, the tool inventory can also be reduced, and costs saved as a result. heimatec developed the flexible heimatec.u-tec® tool change system for this purpose, which has become established in the market in recent years, and allows machining companies to utilize different adapters for a wide variety of machining tasks.

The driven heimatec.u-tec® tools are designed with a collect chuck mount according to DIN 6499, which allows the user to use the driven tools without additional tool adapters.

As an option, different changer inserts with standard tool change inserts such as Weldon, Kombidorn, collect chuck mounts (including extended) or customer-specific tool change inserts can be used in the heimatec.u-tec® tools. With the heimatec.u-tec® system, a cylindrical polygon is positioned in the tool spindles behind the collect chuck cone. This design enables huge force transfer during the machining process. The goal of the engineers was to find an optimum, where on one hand load steps are avoided, but on the other hand high force transmission is possible.

The tools fitted with u-tec® are supplied with a conventional clamping nut. This must be removed before inserting the tool change inserts. The u-tec® tool change inserts also have a cylindrical polygon after the collet chuck cone, and are supplied as a unit with an integrated clamping nut. The tool change inserts can therefore be inserted directly into the standard u-tec® tool.

When doing so, slight turning of the polygon of the tool change insert allows it to locate the tool spindle polygon.

There is no chance of incorrect operation, because the clamping nut of the tool change inserts can only be screwed in after the polygons are located correctly. Finally, the clamping nut is tightened in the tool spindle with the appropriate torque for the size.

The special feature of the heimatec u-tec® change system is the significant improvement of the torque transmission while at the same time the strength and stiffness of the complete tool system is increased. The short mounting length is another special feature of u-tec®. The associated short design length ensures exceptionally stable clamping of the cutting tool with low cantilever forces, leading to excellent machining results and a long service life of the cutters.

The preference for BMT tools with the u-tec® System are the driven tools with a so-called combined bearing, fitted with tapered roller and spindle bearings. Tapered bearings are able to transmit extremely high radial and axial forces. This bearing combination reduces the total heat generation compared with tools only fitted with tapered bearings. The service life is also substantially improved compared with tools which only have spindle bearings.

Easy-quick HT allows tool changes in seconds

The company has developed the easy-quick HT series specially for fast changes in the area of driven and static tools. This means different tool change inserts with market-standard tool mounts can be preset outside the tool machine and when required, can be simply, safely and quickly installed by the machine operator with one hand. The machine downtimes are reduced significantly with the help of the easy-quick HT. The base tools remain in the machine, so that little effort is required to install the preset tool change inserts.

Every easy-quick HT fast tool change insert is fitted with a locating pin, which prevents incorrect handling of the tool change inserts. The design of the system provides high stiffness with the largest possible force transfer and highest precision. In addition, the overall tooling costs are reduced thanks to the multiple and flexible use of the easy-quick base tools. Custom tool mounts can also be implemented cost-effectively.

New standard and special tools for Capto® mounts

Coromant Capto® is an internationally popular modular fast change tool system, which can be used in all machine types. The special advantage is the substantial reduction of the setup and change times, whilst retaining high tool flexibility. With the heimatec.Capto™, heimatec is extending its range of modular fast change tool systems. As well as a wide range of standard tools with Capto® mounts, the heimatec.Capto™ programme also offers a multitude of specific tool mounts with machine-optimized designs.

The modular heimatec.Capto™ fast change system has a compact design with short projection lengths, which allows high cutting speeds to be achieved with the greatest possible tool flexibility. For users of tools with Capto® mounts, the heimatec.Capto™ fast change tool system offers a wide range of benefits, such as the easiest possible handling and fast tool changes, high flexibility due to extensive modular design, as well as precise cooling with internal coolant supply.

The heimatec.Capto™ quick-change system is available for Capto sizes C3, C4, C5, C6, C8 and C10.
