Existing Condition of PCB Drilling Industry
PCB develops from single layer to double sides and multiple layers, and then to high density, high precision and high reliability. In this way, more and more micropores are formed on PCB board, of which 0.1-0.3mm holes account for more than 80% of the board surface. Therefore, the ultra-high-speed motorized spindle, which can drill large holes strongly and also small holes efficiently and accurately, plays an important role.
Continuous innovation, processing transformation
PCB drilling air-bearing spindle ofHaozhi Industrial, with its ultra high revolving speed and accuracy, upgradePCB drilling:
Similar air-bearing Spindle on the Market
Maximal speed (RPM)
Spindle Power (Kw)
Start and Stop Time (S)
Air Consumption (L/min)
Increase of Comprehensive Efficiency
Remark: efficiencyimprovement is based on the data obtained from comprehensive start and stoptime and high-speed process. Above data are from laboratory test.
The service life and precisionmaintenance of air-bearing spindle can be prolonged significantly owing tocontactless and “zero-wearing” characteristics. Haozhi air-bearing Spindle, adoptingbearings made of self-lubricating and wear-resistant material, high reliabilitybroach mechanism and superpower motor, can obtain “permanent life” except forabnormal use.
Ultimate Start and Stop Speed
The spindle canachieve direct acceleration to 200,000rpm from less than 4s, while accelerationof conventional spindle is 10-12s. Generally, tool is changed at every 6minutes. Therefore, more than 3% efficiency can be improved only through startand stop.
Ultrafast Small Hole Drilling Capacity
In internal testdemonstration, the efficiency is improved by more than 12% in drilling smallholes with less than 0.2mm diameter.
With as high as0.16N.m low-speed torsion and 6.35mm tool continuously processing more than10,000 holes (S20000 F0.3 R5.03*1.6mm FR4), our spindle can easily deal withall kinds of thick plates and hard plates.
DQF-250B.S as anall-round, super-high-speed air-bearing motorized spindle can achieve 250,000rpm maximum speed. With subversive technology, while meeting large holedrilling requirements, our spindle is significantly improved in small holedrilling capacity compared with the spindle with 200,000 rpm. With overallefficiency increased by more than 15%, we brings super vales to customers! Thetechnical indicators are as follows:
Maximal operation speed (RPM)
Rated power S6 (Kw)
Rated torque S6 (N.m)
Air volume of bearing (L/min)
