Screw Machine Products

Screw machinery, is considered one of the fastest and most cost-effective method of small rotary part manufacturing.

Screw machines may be referred to as:

• Screw machine (automatic lathe) – a small to medium-sized automatic lathe that is mechanically automated via cams

• Screw machine (turning centre) – a small to medium-sized turning center that is electronically automated via CNC

• Turned lathe –now rarely call a screw machine

CNC - a process used in the manufacturing industry that involves the use of computers to control machine tools

Lathe- piece of material which is to be shaped round and round against a tool that is held steadily by an operator.

The term screw machine might be slightly misleading as the machine don’t actually screw anything nor does it thread materials, although threading is one of it’s function.

A screw machine’s purpose is to spin on a very quick rotating lathe which shaves metal down to a desired size

There are two types of screw machines:

• Turrett –also called Brown & Sharpe, mounts the work-piece on a vertical ram which works into the lathe

• Swiss – mounts the work-piece on a rotary slide.

While these two types function differently, their benefits and outputs are essentially the same. However, the Swiss machine is better at more precise work.

Different types of screw machines are capable of different process:

• Knurling - performed for producing indentations on a part of a work-piece

• Thread rolling-is the preferred method for producing strong, smooth, precise and uniform external thread forms

Screw machinery offers design capabilities and structural benefits which cannot be cost-effectively reproduced with any other manufacturing method.A limitless variety of custom metal parts to deliver precision tolerances by turning are produced through screw machinery:

• Speciality fasteners

• Metal knobs

• Miniature medical instruments

• Bio implants

• Tire gauges

• Threaded rods

• Splines

• Spindles

• Fittings

Not only can metal parts be shaped by screw machinery, but can also be surfaced. The turning process can produce a smooth, near-polished finish or it can produce a knurled finish, which is the process of creating a patterned texture on the surface of a metal to provide grip.

Common knurling applications include: tool handles, metal flashlights, knurled nuts and knurled handles.

For the production of screw heads, both thread rolling and thread forming processes are employed. These processes involve pressing a shaped die against a work-piece.

Thread rolling and forming are cold forming processes, which requires a minimum threshold of ductility from the involved work-pieces. Metals forming processes must be able to be formed by comprehensive force at low temperatures.

Purchasing Tips:

• Work with a supplier that is committed to a long term relationship

• Has the technical expertise that’s matched with the right equipment to support needs

• Selecting a supplier based solely on low bidding could cause delivery and production to suffer immensely

• Supplier should provide information on non-recurring costs related to production order

• Cost of programming tool design, fixtures and cam should not appear on repeated orders.

• Makes better business sense to have this cost differentiated from the part cost.
