Milling Spindles
Milling Spindles
Riya Electrodes offers ultra-precision, high-speed HES Series Milling Spindles that allow users a much larger variety of operations with existing equipment. Conventional milling machines and machining centres can now do high-speed machining, small diameter drilling and milling with extremely good surface finishes with the HES Series. It features a protection circuit to stop the motor automatically in case of overload ensuring safe and smooth operation.
- 6,000-50,000 min-1, maximum output 250 W – the HES series motor is a brushless DC motor that utilises hall elements and rare-earth magnets to realize max output 250 W in a very compact size
- Ceramic bearings – the spindle uses a double pair of ceramic bearings in the front and in the rear
- This arrangement maximises both radial and axial rigidity to insure extremely high-precision cutting
- The motor also uses ceramic bearings to maximise life expectancy
- Smooth rotation – the absence of a commutator and the use of a photo coupler sending a feedback signal of 48 pulses per revolution result in very smooth rotation with low vibration throughout the speed range
- One-piece motor and spindle construction – the motor and spindle are built as a single unit minimising size and weight and allowing usage on a very wide variety or machines
- Emergency connector – the system incorporates an emergency, breakaway connector to help prevent system damage in case the machine’s main spindle is rotated accidentally
- Excellent durability by air-cooling system – air-cooling motor uses a small volume of air (30 L/min) to prevent heat build-up and allow long continuous operation
- Best for small diameter drilling and milling – less than Ø 2 mm small diameter drilling and milling with extremely good surface finishes, using a high-speed brushless motor
- Cooling air – clean dry air is required to cool the motor and protect the spindle from contaminants, so necessary to use a filter and regulator (proper air pressure 0.2-0.3 Mpa) (use air line kit AL-0201) Large variety of tapers available – BT, NT, CAT, IT, and HSK A tapers are available
- Protection circuit – the control unit is compact and lightweight
