Screw machines are types of automated lathes used to fabricate turned parts such as screws, fasteners and nuts. Automatic screw machines can perform many operations. In the machining process of screws or parts, a screw cutting machine uses feedstock (a long rod of material) and automatically turns, faces and cuts the parts. The process continues as the rod advances and the next part cuts in a similar manner. An automatic screw machine can have a single spindle or multiple spindles. Multi-spindle machines have the advantage of producing numerous similar components simultaneously.

Screw machine manufacturers can produce automatic screw machines with multiple spindles that can fit with different attachments to perform different tasks. A type of automatic screw machine, called a Swiss screw machine, is best when precise and close tolerance parts are a requirement. A screw machine is ideally suited for high-volume production of parts at low-costs.

If you need industrial screw machines for your business, some options you may consider are:

1. Find screw machine suppliers that offer new or used screw machines for sale.

2. Choose screw machine services that include repairs, tooling and replacement parts.

3. Consider remanufacturing or rebuilding your existing industrial screw machines.

The best contacts and resources to help you get it done

Select screw machine sellers with a good inventory of machines

Whether you are looking for a new or a used screw machine for sale, finding screw machine distributors that have a good assortment of different brand products is important. Likewise, a distributor should offer technical assistance, repair parts, tooling and attachments for both new and used machines. Save time and money by buying from full line stocking distributors.

I recommend: Davenport Machine offers various models of this product, attachments, replacement parts and services such as technical assistance. Pride Machinery carries different brand new and used machines. It has a large selection of automatic machines. OttoMatics sells different brand used machines. The product list includes Davenport, Conomatic and Brown & Sharpe. Nova Machinery is another supplier of used and rebuilt machines. Many different brands are also available for sale.

Keep productivity high by having the right services and screw machine parts

Machines can breakdown and cause downtime in business operations. Attachments like cross slides, thread rolls and countersinks are important for an industrial screw machine. Be prepared for any problems by getting repair services, tools or replacement parts for machinery.

I recommend: International Screw Machine Services is a one-stop source for replacement parts, tooling, and repair services for a variety of different lines that includes Davenport machines. There are products for single, multi-spindle and Swiss screw machines. Champion Screw Machine Engineering offers replacement parts, tooling and attachments for Davenport, National Acme, Conomatic and others. National Acme machines are also available for sale and you can customize them.

Maintain an industrial screw machine running in optimum condition

When you do not want to buy new machinery and have older machines that are generally in good order, retrofitting, rebuilding or remanufacturing can be a good alternative. Rebuilding or remanufacturing of existing screw cutting machines can be a good option to keep your machinery in good condition and to update certain features. It can also improve performance, productivity and profitability.

I recommend: Nowak Products has a rebuilding/remanufacturing program for Davenport machines. This company offers complete and partial remanufacturing services. Jelenic Machinery also offers rebuilding services for National Acme machines and can re-condition screw machine parts.

Tips & Tactics

Helpful advice for making the most of this Guide

• •  When choosing screw machines for your business, determining your production requirements are essential. Multi-spindle (6 to 8 spindles), automatic screw machines are a good choice when run time and production speed are important. In addition, you should consider which machine could produce parts at the lowest cost per part.
