High Volume Precision Turned Parts FAQ

We have answers to the most commonly asked questions regarding high volume precision turned parts.

What is Precision Screw Machining?

A Precision Screw Machine is an automated turning machine that continually makes a number of finished parts from bar stock (raw purified metal that is available in a variety of shapes and lengths). At Avanti Engineering, our screw machining equipment can handle more than metals. It can handle a variety of materials such as:

Alloy Steel
Aluminum
Plastics
Stainless Steel
Brass
Bronze
Copper

What is the biggest advantage to using a screw machine?

Using a screw machine reduces the time required to machine a part. That translates into lower costs and a faster turnaround time for the consumer. In addition, screw machines offer a level of precision and repeatability that is unmatched by any other machine or human.

What is high volume machining?

High volume machining means that a machine can process a very high volume of pieces in a relatively short amount of time. At Avanti Engineering, we can handle orders of up to 20 million pieces (or as few as 1,000) in a single order and in a short amount of time. We also have a just-in-time (JIT) manufacturing and delivery program that allows us to provide support for Kanban inventory systems.

How does the Precision Screw Machine work?

The bar stock moves through the spindle (the rotating axis of the machine) and is held by a collet (the part that grips the bar stock, usually in a size range of 1/16” – 2.5”). It is also commonly called a bar machine.

What kind of equipment do you use to make high volume precision turned parts?

While every company differs in the machining equipment they use, Avanti Engineering offers:

What is the difference between a screw machine and lathe machines?

Screw machines are capable of producing large product volumes and require a more extensive set-up than an engine or turret lathe. Once they are running, they are simpler to maintain and one operator can monitor the operation of several different machines.

An engine lathe is also used to cut metal, but cuts shapes into metal as it is turned. It takes the least amount of time to set up, but the most amount of skilled labor and time to actually produce a part.

A turret lathe is similar to an engine lathe. It requires greater set-up time, but can produce a higher volume of product with a lower-skilled operator once the set-up process is complete.
