ALM's ball screw advantages
1.High transfer efficiency
Balls with free motion in the ball screw assembly transfer the force and motion between screw and nut.This transfer mode replaces the traditional transfer mode that screw shaft and nut effect directly.Therefore the minimum rolling friction takes place of the sliding friction of traditional screw.The transfer efficiency of ALM ball screw will reach more than 90%.The drive torque of transfer unit reduces to 1/3 of sliding screw.This also greatly reduces the heat release.
2.High positioning accuracy
ALM Ball screw has low heat release,small temperature increase and with actions of pre-stretch and eliminating axial clearance in the process,which make ball screw have high positioning accuracy and repeating positioning accuracy.Positioning deviation can be 0.002mm per 300mm travel.
3.Clean and smooth,excellent surface finish
ALM Ball screw has no sticky friction.ISO management systems ensure strict performance during production and experienced talent staff combing precision machine and optimized process flow causing super quality smooth ball screw.Each ball screw will go through ultrasonic before assembly.
4.Long service life
Since the strict control of ball screw groove shapes,surface hardness and material selection,the actual life of ALM ball screw is much longer.
5.Good synchronization
Due to smooth running,axial clearance elimination and consistency in manufacturing,several sets of ball screw assembly can drive the same unit or several identical parts to obtain the good synchronization.
ALM originally established in year of 2005.From a small factory,ALM nowadays own factory 7000 square meters,109 employees.Above 8 technical engineers are with over 20 years' experience in linear motion filed.
With the products covering more than 72 countries in Europe,North America,South Asia,Middle East,Africa,Latin America and Australia,New Zealand etc.With super quality and service,ALM has been widely recognized and highly valued by its high-end and picky customers,and thus remains at the top of their vendor lists.In year of 2016,our Dr team carryied out new innovation linear motor testing.
ALM key production machines are imported,like high precision CNC grinding machine,3 axis,4 axis machining centre,internal and external grinding centre,CNC lathe.With advanced production management enables ALM obtain the quality certificate ISO9001:2008 and IATF16949.The R&D achievements over many years bring ALM more than 26 national patents.
