Reference Stations

(Squaring/Centering or Locating Stations)

“Reference Stations” are used to precisely locate a piece of glass for a further processing step. Also called “Squaring”, “Centering” or “Locating” Stations, the design of these machine can be relatively straightforward, to very complex. It is necessary to understand the requirements or specifications of the next processing step, especially what tolerance is required. The tolerance greatly affects the complexity of the design, and typically the cost of the system goes up as the tolerance requirements become tighter. Of course, the glass shape will usually determine the design and the number of axes required. Other things to consider include: Incoming glass tolerance, Incoming glass edge, e.g. raw, ground Flat glass or bent glass. Rectangles, vs. shaped glass (automotive shapes such as quarterlites, sidelites, backlites, windshields, and symmetrical vs. asymmetrical shapes), Minimum and maximum sizes, Cycle time, Tolerance requirements, Centering of the part or edge referencing to one or two sides, Manually loaded location systems or automatically loaded (via conveyor or shuttle), Physical location or non-contact location (laser, vision, etc.).

Spec

Glass Thickness Range: 3 - 12 mm (other thicknesses optional)

Hole Diameter (Min.): 4mm (smaller sizes optional)

Throat Depth: 20 inches (others optional)

Misalignment Tolerance: Maximum .05 mm (distance between top and bottom of drill centers)

Spindle Run Out: within 0.0125mm

Drill Shank Run Out: Within 0.038mm (one inch from spindle nose)

Features

Spindle heads are removable for repair or rebuild

Alignment System incorporated providing fast, easy alignment of the upper spindle to the lower spindle

Coolant water supplied directly to the spindles via a rotary joint and valving – restricts flow during non-drilling time

Lubrication – Oil Mist System for spindles is included

Servo ballscrew-driven arms provide separately programmable speeds for approach, drill, and chamfer.

Top drill can be programmed to feed fully through to “clean up” hole edges.

Spindle rpm’s are programmable via AC drive.

All Moving Components are protected from the water (in the back of the machine)

Thickness of glass can be programmed as well as top and bottom feed depths.

Options

Servo Feed

Large Hole Capability

Auto Load/Unload (in-line systems)

Auto Squaring

Auto Positioning Systems for Drill/Glass

Auto Stoning

Laser Drill Bit Measurement

Granite Bases

Drill bit measurement can provide for a quicker setup after drill bit change.

Slug-Ejector used to protect the lower drill bit against the drilled core falling onto it.

Applications

Drilling and chamfering holes in glass for windows, doors, and other applications

Drilling and chamfering holes in glass for mounting electronics.

Drilling and chamfering holes in glass for mounting artwork.
