How we got here

Glass—How We Got Here

Glass—discovered over 4,000 years ago, considered precious, was used by royalty as well as for religious purposes. Glass making reached a high point during the time of the Romans both in terms of quality and practical usefulness. By the 7th century, Syria had understood the methodology for forming flat glass based on molten "blobs" of glass being spun on a disc using centrifugal force to cause them to flatten out, a method that would last for most of the next ten centuries. Stained glass emerged from the Middle Ages as the main contribution of that period.

The process of making "sheet glass" early in the 1900s was carried out by a glass "ribbon" vertically oriented from a pool of molten glass. The process, while a step forward, provided a sheet, which had distortion problems due to variations in the viscosity of the molten mixture from which it was drawn.

A pane free from distortion—something truly necessary for window openings of different types in moving vehicles—required a different process to be developed and such was the case with the development of "plate" glass obtained by flattening molten glass on table via a rolling action, then grinding and polishing it until acceptable results were obtained. For the most part, this process is no longer used in the United States.

Modern glass - the float glass process

Modern Glass - The Float Glass Process

Float glass made its appearance in 1959. The process of making "float" glass begins with molten glass flowing from the furnace in which it has been prepared, from which it is displaced onto a sea of molten tin and in the process forms as an unbroken "ribbon." The ribbon of glass is drawn through the "sea" of tin on which it is "floated" and at its exit is guided, while being supported on rollers, through an annealing lehr. In this part of the process, it is cooled under controlled conditions until, at its conclusion, it's almost at ambient temperature.

The character of float glass is such that it is almost colorless and freely transmits light with an efficiency of 75% to 92%, depending on thickness. In addition, float glass at the end of the process is flat, fire-finished and its surfaces, for all practical purposes, are parallel and ready to be processed and machined via modern CNC cutting tables and machining centers.

Heat treated glass

Heat Treated Glass

Float glass may undergo a process called "heat treating" in order to meet certain standards required for safety glazing applications. In this subsequent process the float glass, typically used for architectural glass purposes, is cut to its required sizes first, then moved through a furnace to achieve a uniform temperature of about 1,150° F.

At the end of the process, the glass leaves the furnace and is cooled quickly via blowing air on both of its surfaces at the same time, which locks the surface state in "high compression" and the interior state in one of "compensating tension." These zones are about 20/60/20 in their relationship to each other, with the outside surfaces being about 20% of the glass thickness and the interior 60%.

The basic characteristics of the glass are not altered with its heat treatment, while those of its physical properties are improved—that is flexural and tensile strength along with increased resistance to thermal stress and shock—while at the same time, the heat treatment does not reduce its deflection property for any specific load.

Glass - strength for design and structural use

Glass - Strength for Design and Structural Use

Glass has emerged with increasing popularity for the possibility of its use in minimally supported applications, such as glass canopies and balustrades or stairways, which find their way into many commercial construction projects.

Such applications require designers to confirm that the use of glass meets the appropriate design loads. The strength characteristic of glass assumes an important role in choosing the best glass design solution for a project. There is a variety of reference tools available to help in this process.

The ASTM International’s ASTM E 1300 Standard Practice for Determining Load Resistance of Glass in Buildings was developed to help people design with glass. This standard describes procedures for determining load resistance of different types of glass for a specified probability of breakage. The standard includes design charts for such types of glass as monolithic, laminated, and insulating glass constructions with one, two, three, and four-sided support conditions.


Glass - Flat panel applications

Glass - Flat Panel Applications

The use of glass in the housing and construction industries continues to find new flat panel applications such as shower doors and enclosures, furniture tops, counter tops, entry doors, beveled mirrors, grooved shelving, and even decorative glass.

Commercial Glass - Overview

Commercial Glass

Using glass as a building material has become increasingly popular in recent years. More and more glass is used in construction. With today’s technology, less metal is required to fasten the glass to other substrates. Glass is also used as a design feature in many instances.

CMS/Brembana's complete range of cutting tables, vertical and horizontal CNC machining centers, double edgers, automatic handling systems, and more, covers the range of machining processes required for today's manufacturers.

Processing Laminated "Heavy Glass"

A piece of "heavy laminated glass" is machined, with dimensions of 3210 x 2400 x 30 (15+15) mm thick.

Profile, a vertical CNC machining center for glass, is resting the part to be worked at 5° from true vertical.

The video shows the steps of the process as follows:

  • Automatically measuring the height
    Glass with a weight greater than 580 kg (1276 lbs.) is held by Profile's vacuum cups which are automatically selected
    • NOTE: Profile does NOT rest the "heavy glass" panel on the machine's infeed rollers, but vacuum clamps and holds the part just slightly above the rollers (see the paper slipped between) so that premature wear out of the rollers is avoided, as well as compromising edge quality, which would occur during CNC processing if the panel was left to rest on the rollers.
  • Selection of tools
  • Pre-wash of suction (vacuum) cups to guarantee cleanliness and a perfect vacuum
  • All four edges are processed in five passes: processing with three diamond wheels + one resin + one polishing
  • Views of rough, medium, fine, resin, and polishing

Vertec—Cardinal Glass Case Study Shower Doors

The Cardinal Shower Enclosures case study gives an overview on how CMS/Brembana's Vertec vertical glass processing technology impacted their production operations: time savings in producing their components, ease of information input, ease of loading the machine.

Cardinal provides an explanation of how the machines work, and it's impressive technology for hole drilling from both the front and the back, along with its "halo flood" technology (in which the part is kept 1 mm from the "halo" and rides on a cushion of water from both front and back), guaranteeing good holes without any possible scratching of the surfaces.

Cardinal also explains remake levels have decreased and productive volume has increased.
