MAPAL – Miniaturised Clamping Chucks

Thanks to additive manufacturing, MAPAL now offers hydraulic chucks in miniature format with HSK E25 connection, for example for the direct clamping of tools with a diameter of 3 mm. These meet all the demands on chucks for the miniature sector with respect to radial run-out accuracy, balancing value, cooling lubricant supply and handling.

In order to guarantee perfect radial run-out accuracy, innovative clamping chamber systems are integrated into the new chucks that fit tightly against the shank of the tool. They are fitted with dirt grooves as protection against micro-soiling. The demanded balancing value is ensured thanks to the internal balancing geometries and supporting structures that also aid the optimisation of weight and strength. The miniature chucks allow homogeneous acceleration and deceleration of the whole tool system of chuck and tool for less loading of the spindle.

The innovative manufacturing method has also enabled the chucks for the miniature sector to be equipped with decentralised coolant outlets. These outlets are designed using parameters such as coolant pressure, setting dimension and spindle speed so that they deliver the cooling lubricant precisely to the cutting edge. In the best case, a metered total-loss lubrication system is achieved that eliminates the need for subsequent cleaning of the parts.

The new miniature chucks from MAPAL allow quick and simple clamping of the tool. Neither training courses nor high setup costs or expensive peripherals are required for implementation of the chucks.

The new small hydraulic chucks also offer new possibilities for the clamping of workpieces. For example, for the clamping of artificial hip joint balls. Specially formed clamping chambers inside the chuck and a special outside geometry ensure that the balls are very precisely and at the same time gently clamped. Particularly in medical technology, topics such as reproducible precision are taking on enormous importance – and this is ensured during machining thanks to the new chucks.

Horn Thread Cutting Tools from M1 to M2.5

DCG thread milling cutters for M1 to M2.5

Thread Production in hard-to-cut materials

Horn presents new developments in the DCG thread milling system. Suitable for producing threads from M1 to M2.5 (metric ISO threads DIN 13–20), the tools extend the possible applications of the DCG series for the reliable milling of threads. They have extremely sharp cutting edges and are suitable for universal use thanks to their coating. The solid carbide milling cutters are available as standard up to a thread length of 2 x D. They demonstrate their special capabilities and efficiency when machining steels, stainless steels, cast iron, non-ferrous metals and in particular hard-to-cut materials used in the medical technology sector, for example.

DCG solid carbide milling cutters have been proving themselves in the production of threads sized from M3 to M12 for many years. As the single-row milling cutters can be used for different pitches, a high degree of flexibility is guaranteed.
