Meets micro mill and drill manufacturers spindle speed requirements for many applications where small hole drilling and light milling are required.
Fully tool changeable spindles for transfer from the machine magazine to the main spindle without the need to connect the air supply.
All spindles are guaranteed to be less than 1um T.I.R, in spindle taper allowing for excellent surface finish and extended tool life.
True High Speed Machining can be achieved with the high speed and accuracy of the HPS250 / 500.
Constant cooling and lubrication of the spindle and motor ensures minimal thermal growth, which promotes extremely high accuracy and long bearing life.
The motor and spindle are built as a single unit to minimize length and weight for usage on a wide variety of machines. Spindle and motor constructed of precision ground SUS-416.
Gearless operation eliminates heat and vibration affording high RPM for micro milling and micro drilling of all materials. Helps extend spindle bearing and cutting tool life.
Our air line kit provides atomized air and oil to cool, lubricate and purge the spindle and motor for extended machining operations that is typical for high speed machining. Unused lubrication oil is returned to the reservoir.
Machines main spindle is used only to hold the HPS Spindle, providing longer main spindle life. Running a machine spindle at the machines maximum rpm for extended periods of time will severely affect the machines spindle longevity.
Positioning Block ( Optional )
We provide the positioning block to mate the HPS spindle with the machine. Several designs are available depending on the machine manufacturer and machine model and year of manufacture.
