Manufacturing Operations

Intech can perform a variety of manufacturing operations to produce a finished part from raw materials.  Most Screw Machine jobs start their life as a long bar of round, hexagonal or square material.  The material is usually a metal or plastic.  The material is then fed into the automatic Screw Machine where it is spun at high speed and various tools advanced to cut material away from the initial shape.  This kind of manufacturing is all about removing material from the raw stock until it looks like the finished part.  The final operation is to cut the finished part away from the raw stock and advance the stock to start over again.

Some of the manufacturing operations that can be accomplished on a Screw Machine include:

Forming Forming is used to cut away material from the outside of the part to reveal the outline shape.  Forming is performed using a tool that has been specifically cut to have the reverse outline from the part being formed.
Box cutting Box cutting is used to cut away material from the end of the stock to reduce the diameter.
Drilling Drilling is what it sounds like.  A drill bit is advanced into the spinning stock to cut away material from the inside of the part.  However, the Screw Machines can also drill through the side of the part.  See Cross-drilling below
Cross Drilling Cross drilling is when the Screw Machine stop the stock from rotating and advances a spinning drill into the side of the part.  This is a common operation for turned parts that may be mated with other parts.
Tapping Tapping is used to cut female threads in a hole that has been previously drilled.
Die cutting  Die cutting is used to cut male threads on the exposed end of the part.
Thread rolling Thread rolling, like die cutting, is used to create male threads on the exposed end of the part.  Depending on the material and the application, rolled threads can be stronger than die-cut threads and may be a better choice. 
Knurling Knurling is used to create an easy to grip surface on the outside of the part.  Knurling does not actually remove any material from the spinning part.  Rather it moves it around until small diamond-shaped mounds are formed on the surface.

These are just some of the operations that can be performed on Intech's automatic Screw Machines.  The Screw Machines can hold a number of tools and can perform multiple operations in sequence without human intervention, creating finished parts that can be surprisingly complex.  For parts that are well suited to manufacture on a Screw Machine, the Screw Machine is unrivaled in its efficiency.
