High-Speed 500W PCB Drilling Spindle

Model no. PCB-04860

With a rich experience of spindle motors, NK Automations provides High-frequency spindles with precision ultra-high-speed ceramic bearings for précised CNC machine applications like Sheet Cutting and PCB drilling. The spindle is small enough for light machines, but powerful enough to get the job done.

Also, it has superior quality, enhanced reliability, smooth motion and balancing stability.

The spindle structure is an ATC mechanism, and the tool collet is 3.175mm

PCB-04860 with 0.5 kw and 60,000 rpm High frequency Spindle with Ultra high speed ceramic bearings has a robust construction and is highly précised and is in accordance with set industrial standards.

Application:

Denture Forming
Glass Ceramic
CNC PCB Drilling Machine
Milling and composite routing (CFRP materials)
Glass grinding (mobile phone/tablet screens)

With a compact design at high speed, low noise, and long and stable operational life. NK Automations' spindles for CNC machines are small enough for light machines but powerful enough to get the job done. With rpm up to 60,000 rpm range, motor power as per requirement, and static runout: ≤2.0μm, the spindle is ideal for sheet cutting, PCB drilling, dentures making, mobile cover making, and other similar applications.

Other features include superior quality, enhanced reliability, smooth motion, and balancing stability. The spindles are capable of completing very complex tasks very easily.

High precision: Spindle static runout is ≤0.002mm, tapered bore runout is≤0.001mm. It has high dynamic precision and stability of spindle during machining, which can effectively ensure the stability and consistency of the work piece dimension.
High speed: The max. Speed of the spindle can reach up to 60000 rpm.
High degree of finish: The roughness of the finished surface is only Ra0.05, and the surface finish is remarkable.
Ultra long nose: Easy to solve the problems such as denture groove of traditional spindle is difficult to be machined and the cutter is vulnerable to be broken, etc.
High energy conservation and cooling: Air cooling is adopted, with the min. gas flow of 30L/min and the min. air pressure of 0.05mpa. The lower the calorific value is, the lower the cooling gas flow will be.
Ultra long service life, high stability
Air seal can prevent the dust and coolant from entering the bearing during machining, which can effectively avoid the spindle faults. The spindle is equipped with the motor temperature control sensor to monitor the spindle temperature in machining process in real time.
The high precision ceramic ball bearings can ensure long and reliable operation of the spindle.
The vibration is only 0.8mm/s. The continuous running sound is ≤68dBA, which achieves low noise machining at office level.
