ALM relying on the University of Manchester,specializes in screw thread technology and processes the world's leading technology in terms of grinding wheel dressing,thread grinding,thread cold extrusion,thread tool manufacturing,and thread transmission,which has laid the foundation for the quality of ALM linear motion products.
ALM is one of the world's three hard-rolled cold rolling screw rod technology holders.Unique manufacturer in nut smooth grinding technology,heartless grinding screw technology,super smooth screw technology,screw self-centering and heel knife grinding technology.In addition,with reasonable design and rigorous process control,ALM lead screws fit nicely,run smoothly,left and right motion softness consistent,dynamic smoothness is good,lead screw assemblies transmission efficiency is higher,torque is smaller,motor load is smaller.Both cold rolling and grinding manufacturing technology are available to provide the corresponding products according to customers' requirements.
ALM produces lead screws as per the ball screw processing requirement.Different from most other lead screw manufacturers,ALM cold rolling lead screws is made by a model with a single rolling wheel.ALM lead screw accuracy can be C5.Lead screw hardness can be HRC70,When the lead nuts rotate on screws,no deformed and wiggling nor stuck phenomenon.With ALM unique rare earth alloy nuts,lead screw service life increased by at least 3 times.
