On Stand 310 in Hall 19, Mu-Tools will show the type Mu-HS1 single spindle and Mu-HS2 double spindle machines that have been developed to perform high precision honing operations.
The honing range starts at 0.6mm diameter up to 80mm with honing lengths up to 210mm, depending on the shape of the workpiece. All types of Mu-Tools honing tools can be used on these machines. The QR codes on the packaging boxes can be scanned and the detailed honing tool information can be transferred directly to the program. The machine software can analyse the data of each tool and display the state of wear of the tools at any time, indicating the number of parts machined per honing tool. The chassis of the Mu-HS1 and Mu-HS2 machines is identical and allows the machine type to be configured very quickly. In addition, reinforced elements have been integrated to connect an automatic workpiece loading system.
The spindle has been developed by BBN Mécanique, a specialist in high precision spindles and the maximum speed is 8000rpm with a torque of 11.4Nm. The expansion system is integrated into the spindle and controlled by a micrometric screw system. Specific sensors are connected to the expansion motors as well as to the spindle motor. They allow the recovery of data on torque, heat and current to analyse the cutting forces between the tool and the material as accurately as possible.
The honing movement is carried out by a table coupled to a linear motor, allowing a 350mm stroke and a honing stroke of 210mm. Depending on the geometric defect in the workpiece bore, it is possible to set several honing strokes at different positions in the same program. The workpiece clamping systems can be mechanical or pneumatic.
