Additive manufacturing enables optimised cooling during reaming

Fixed multi-bladed reamers are the means of choice when high cutting values and short machining times are required. Until now, the limitations of conventional manufacturing processes prevented the delivery of coolant to all of the cutting edges on the reamer. The positioning of the coolant outlet, i.e. the bores for the cooling channels was always a compromise.

Now, the application of additive manufacturing has enabled MAPAL to succeed in optimally designing the coolant supply and the shape of the coolant outlet for reaming. The advantages of the new manufacturing process can also be used in the area of fine machining of bores. Thanks to special cooling lubricant outlets, the newly designed multi-bladed reamers of the MonoReam series now deliver the coolant exactly to the cutting edge. This ensures optimum chip removal and optimal cooling as well as efficient lubrication of the cutting edge and the arc land chamfer. This in turn leads to less abrasive wear of the arc land chamfer, better chip removal and optimised machining results.

All reamers of the three MonoReam series are now presented with the new additively manufactured tool heads generating optimised cooling and lubrication – even when using minimum quantity lubrication methods. The MonoReam reamers are available in fixed (600), expandable (700) and adjustable (800) versions. The three series are interchangeable. Available as straight, left-hand fluted and short or long versions, the new reamers are suitable for through holes or blind bores and can be designed with suitable cutting materials, coatings and cutting leads depending on the material to be machined. This ensures that the optimum tool is available for every requirement.
