The multi-edged tool systems offer the advantage that the cutting edges can be changed directly on-site by the customer with one (HPR400) or four (HPR400 plus) cutting edges, and thanks to precisely manufactured insert seats, ensure the highest precision. The focus of current developments is on three new solutions, all aimed at further increasing the productivity of companies and sustainably reducing costs.
Innovative single-shot solution for finishing with high dimensions
In machining situations with high dimensions in finishing, the combination tool with ISO pre-cutting stage and HPR400 system is particularly attractive. It allows for drilling with dimensions of up to 6 mm in a single operation. The ISO cutting part handles the main cutting, while the HPR400 system performs the finishing. For the customer, this means the shortest cycle times. Additionally, the setup effort is eliminated as the cutting edges do not need to be adjusted on the complete tool.
New concept HPR400 plus for flat grooves
The HPR400 plus series has been specifically developed for the machining of flat grooves. The indexable cutting inserts have been explicitly designed for holes with special bottom contours (flat machining or flat groove). The new tool concept with two usable cutting edges improves the cost-effectiveness. Despite the flat groove, the tool and cutting edge are stable and reliable in machining. Applications can be found in almost all swivel bearings and bearing holes where clearance at the bottom of the hole must be ensured.
HPR400 with PKD cutting edges for machining stator housings: Innovative solutions for e-mobility
The HPR400 system is also suitable for the finishing of the stator bore in electric motors. As there is now an increased demand for motors in higher quantities for vehicles in the mid-range segment, the demand for productive solutions is rising.
In contrast to the cutting edges of a fine boring tool, the HPR400 tools with PKD cutting edges do not require adjustment. The machining speeds are significantly higher due to the increased number of cutting edges compared to a fine boring tool. The technology allows for a higher output with less effort, thereby increasing productivity.
Flexible, economical, sustainable, and technologically up to date
With the further developments of the HPR400 and HPR400 plus systems for specific applications, MAPAL emphasizes its commitment to providing customers in the automotive or fluid technology sectors with future-proof solutions for a variety of demanding machining tasks – flexible, economical, sustainable, and technologically up to date.
