ALM ground screw threads are manufactured by an abrasive process that typically occurs in a horizontal setup,the material blank rotates on a long axis between two machining centers,while extremely hard abrasive cutters that are designed to cut a few threads at a time,carve out the threads from the cut blanks.

ALM provides custom service,ball screws can be manufactured according to customer requirements.
With up to 90% efficiency,ALM 16mm ground ball screws are widely used in applications requiring high precision and repeatability,such as:robotics,CNC machines and 3D printers.
The 20mm ground ball screw has high precision and low noise,and is durable.This ball screw can withstand higher loads and has wide application in industrial automation.
ALM's advanced processing technology enables the 25mm ground ball screw to have high durability,high precision and higher load.The ground ball screw is widely used,such as:CNC router,laser cutting machine,and packing machine.
32mm ball screw can maintain long service life by using advanced processing technology.The ball screw has the characteristics of high precision,high stiffness and high speed.Widely used in large automation equipment.
Diameter 40mm ground ball screw has high stiffness and can be designed with large lead to achieve high speed operation.It is suitable for machine tools and other large automation equipment.
Diameter 50mm ground ball screw has the characteristics of high rigidity and high durability.The ball screw can maintain high efficiency with low wear,and can withstand high and ultra-high loads.
Diameter 63mm ground ball screw is a kind of heavy load ball screw that can withstand large axial loads.The ball screw has the characteristics of long service life and low noise.
80mm ground ball screw has the characteristics of high rigidity,high strength,strong resistance to bending,and high reliability.It can bear heavy load and super heavy load.
Diameter 100mm ground ball screws have increased load capacity by maximizing the diameter of balls in relation to the lead,increasing the number of valid load balls and optimizing the shape of ball groove.
ALM high load 120mm ground ball screws have maximized the ball diameter and increased the number of valid load balls for a design that can withstand a super heavy load.
