Professional Lead Screw Manufacturer and Supplier

As a specialized manufacturer and provider of lead screws,we offer a wide range of custom lead screw and nut solutions for the medical,packaging,semiconductor,aerospace and other industries.The leadscrew products we produce include: trapezoidal screw,ACME thread lead screws, triangular thread lead screws,bi-directional lead screws,high speed sliding lead screws and round threaded lead screws,diameter ranging from 2mm-120mm.All leadscrews and nuts are ROHS and CE compliant.

Types of Lead Screws

Lead Screw Thread Types

Trapezoidal Thread(30°):For transmission and position adjustment,widely used in the mechanical industry.
Metric Thread (60°):The most common form of thread used for fastening and precision transmission.
ACME Thread (29°):Inch threads can also be used for fastening connections,but not for high accuracy.
Knuckle Thread:With the same arc thread as ball screw,the transmission is smoother.
Gothic Thread:Gothic double arc thread,offering the advantages of ball screw,is similar a new kind of lead screw.
Self-Reversing Thread:A screw that makes the slide block nut reciprocate without changing the rotation direction of the spindle.

Features of Lead Screw Thread Forming Ways

Thread rolling
The cold working that threads receive during the rolling process strengthens them in tension,shear and fatigue.A rolled thread will increase the thread strength by a minimum of 30% verses a cut thread.
Thread grinding
Thread grinding is done on a grinding machine using specially dressed grinding wheels matching the shape of the threads.The process is usually used to produce accurate threads or threads in hardened materials.
Thread cutting
It is a traditional way of thread forming.Threads are cut with the (CNC)lathe for accuracy and for versatility.Both inch and metric screw threads can be cut using the(CNC)lathe.Compared to thread rolling,cutting process is used when full thread depth is required,when the quantity is small,when the blank is not very accurate,when threading up to a shoulder is required,when threading a tapered thread,or when the material is brittle.
