Rock series
Rock series

Rock is located in the medium-high price segment of straight-line edgers market; this value is given by:

Performance: Double speed compared to other machines with the same number of spindles

Quality: superior finishing level

Precision: extreme accuracy and repeatability

Comfort: no vibration, no noise during processing

Heavyduty: built to last, 15-20 years with intensive use

With these features, Rock becomes the most valuable (most convenient, inexpensive) machine, considering lifetime, maintenance costs, productivity and quality added value.

Rock processing
Rock processing

  • Designed for flat edging with arris

  • Also industrially polished chamfer up to 10mm (Rock 8 and 11), with special metal wheel or high-quality polished chamfer (Rock 10-45)

  • Glass thickness till 40 mm

  • Glass weight up to 2000 Kgs (250 Kgs per meter)

Spindles & cases

Conveyors belts by chains
Conveyors belts by chains

The conveyors belts are driven by a chain system

  • Rubber part in contact with the glass in long lasting anti-cut material

  • The wearing part in contact with the glass can be easily replaced when needed, at a low cost.

Conveyor on guides
Conveyor on guides

  • The concept is based on by pads sliding on guides in tempered steel and stainless steel with an oil film in-between

  • This ensure a long life and a parallel wearing allowing constant quality up to the end

  • Guides are mounted on the structure and replaceable when worn out

  • Pads in a material resistant to glass powder abrasion

  • Centralized automatic lubrication system

Conveyor pads
Conveyor pads

Conveyor pads based on a new patented concept with double material:

  • Body in very hard material with excellent mechanical performances (no flections, no thermal dilatations)

  • Part in contact with guides in Kevlar for wear-less performances

    The soft rubber part in anti-spot rubber.

  • No marks on glass

  • Replaceable

  • Easy maintenance

Spindles driven by belt

Spindles and motors are separated and linked by belt system

  • No vibration from motor to spindles means better quality and longer spindle life

  • Revolution speed perfectly adjusted to the wheel need

  • All spindles managed from the front side

  • Permanent lubrication system

    no maintenance required

Rock uses the same CN platform as Drillmax and Promax

  • 24V voltage on machine board

  • Ethernet connection for data transfer or remote assistance

  • Wheels absorption with precise graphic indication

  • Main functions

    • Automatic removal adjustment

    • Centralized lubrication management

    • Counters:

      • Tools life

      • Total/partial working meters

      • Total/partial working hours

      • Programmed maintenance

      • Alarms

Placed outside the machine to avoid any type of oxidation of the electrical components caused by moisture coming from the machine.

No high voltage on control panel area

Allows easy and quick maintenance

Automatic removal adjustment
Automatic removal adjustment

Glass to be removed is managed by NC trough an Y axis 5mm stroke.

The operator can select the removal on the control panel and the inlet conveyor is automatically adjusted

No manual hand wheel adjustment

How can I getit?

Maybeusing a CNC machine?

Maybeusing a DOUBLE EDGER?

Edge to shape

Edge to Shape: the innovative evolution developed by Stefano Bavelloni and PATENTED by Neptun which allows the straight-line edgers of the Rock series to perform edge processing, with control of the final geometry both in terms of angles and final desired dimensions.

From irregular to 90°an now also from 90°to a defined irregular shape

Edge to shape1




1900mm ±0.5mm



From indefinite shape to square and to size




800mm ±0.5mm

Edge to shape2

From indefinite shape to defined irregular shape


Edge to shape3

Rock evolves from conventional machineinto a real CNC machine

Thanks to CNC solutions, the high precision mechanics, and the new patented conveyor of Rock.

Rock can now be used as an alternative in all the processes that, up to today, could be carried out only by CNC machines or double edgers.

Edge to shape4


  • Thanks to the powerful CNC the angle and the length of the glass are measured by a laser system

  • Glass is introduced by interpolation of Y and C axes

Measure angle

Measure length



Rock series


90° squaring cycle concept

First step:

Processing of the first edge in order to get a good reference (no need to correct the angle in this phase)

Second step

Turn piece 90°and use the first edged side as reference, correct the angle, edge the second one:  Angle 1^2 goes 90°

Third step

Turn piece 90°and use the second edged side as reference, correct the angle, edge the third one:

 Angle 2^3 goes 90°

Fourth step

Turn piece 90°and use the second edged side as reference, correct the angle, edge the fourth one:  Angles 1^2^3^4 go 90°

Edge to shape limits

  • Glass can be processed in four cycles (four sides) provided that the maximum removal is 5mm per step, otherwise it has to be introduced more times

  • Glasses ha to be placed with a minimum distance of 100cm between each other in order to allow all adjustments

  • Tolerances:

    • 0,3mm/m on diagonals

    • 0,5mm/m on final dimensions

    • Maximum angle correction:

      •  0°24’ with standard inlet

      •  0°17’ with 3200mm inlet

Edge to shape what does angle correction 0 24 or 0 17 mean
Edge-to-shapeWhat does angle correction 0°24’ or 0°17’ mean?







With standard inlet/outlet

With 3200mm inlet/outlet

Rock series


  • Possibility to perform processes that are typical for double edging machines without incurring in high investments in terms of capital and required space.

  • Possibility to prepare glass sheets for other processing phases on CNC work centers, limiting the further processing time only to the drilling or milling phases.

  • No set up time, so flexibility and convenience in using it also for single pieces and small batches

  • Possibility to process multiple glasses simultaneously by job list up to 10 pieces in the same time

Ets job list
ETS Job list

The operator inserts the dimensions of the glass sheets to be processed in the job list and processes the pieces.

Once finished, the CN displays the final obtained dimension, in case of non conformity a red number is shown.

In case of irregular shapes, the four lengths are imputed

Conveyors module can be:

  • Lengh

    • Standard  2000mm

    • Longer  3200mm

  • Height

    • Standard

    • Higher  +1000mm

Independent motorization on inlet
Independent motorization on inlet

Independent motorization allows to stop the inlet conveyor for the loading phase.

By a foot command operator can start & stop conveyor with hands free

  • Safe loading operation

  • Possibility to load while machine ids processing

Ets predisposition
ETS predisposition

With ETS predisposition, there are no ETS functions but all mechanical ETS parts are already mounted.

It results cheaper when afterwards ETS would be implemented as no parts has to be replaced.

Remote service
Remote service

Remote service is a package consisting in:

  • Hardware firewall for internet connection between Neptun central service and the installed machine

    • The price of the initial kit includes the first 12 month service

  • Free software upgrades: in case a new software release is issued, Neptun provide it free of charge otherwise would be charges (example ETS2 upgrade for non square would cost € 4.000)
