The HSK-A63 option has been integrated into our previous 40T 15k inline spindle design, and this will be built on our production floor. The HSK-A63 utilizes clamping unit style B by OTT-JAKOB. The HSK-63A spindle option is currently available on the EC-400, EC-500, VC-400/SS, UMC-1000/SS, the VM-2, VM-3, and VM-6 with optional max speeds of 12,000 or 15,000 RPM
The HSK-F63 option will be purchased as a complete spindle from HSD Mechatronics. It will have a max speed of 25,000 RPM. The HSK-F63 option is only available on the GR-712 5-axis and the GM-2-5ax.
The HSK-A63 option will be purchased as a complete spindle from HSD Mechatronics. It will have a max speed of 20,000 RPM. The HSK-A63 option is only available on the VR-Series.
The HSK type toolholders are unlike other tool-holding solutions we use in that they are hollow, shorter, and have a steeper shank. The acronym HSK is translated from German as hollow taper shank. Since they are hollow and shorter, they are lighter and have the ability to perform faster tool changes. They clamp the toolholder radially and axially, contacting the toolholder with the spindle face. HSK toolholders are in general more rigid and thus reduce any noise from resonant frequencies generated within the system. This leads to reduced chatter and an overall exemplary toolholding system.
