A bridge-saw program normally contains several different speed commands. Treating them as interchangeable can damage the slab, shorten blade life, or create an unsafe machine command.
The four most important values are RPM, feed rate, plunge speed, and ramp-in or ramp-out.
What each setting controls
RPM
RPM is the blade’s rotational speed.
The maximum RPM printed on a blade is a safety ceiling—not necessarily the correct operating target. Never exceed the lowest applicable limit among the blade, saw, arbor or adapter, flange system, and manufacturer instructions.
Feed rate
Feed rate is the forward speed of the blade through the slab.
Too much feed can cause chipping, wandering, vibration, overloading, and poor finish quality. Excessively low feed can also create rubbing, heat, or glazing. The correct rate depends on material, thickness, blade, diameter, saw condition, water delivery, and cut type.
Plunge speed
Plunge speed is the downward speed used when entering the material.
A plunge that is too aggressive can shock the blade and slab. The established 16- and 18-inch KING digital starting plunge is 0.1 m/min, or 3.94 in/min. The 14-inch starting plunge is 0.09 m/min, or 3.54 in/min.
Ramp-in and ramp-out
Ramp-in controls the transition into production feed. Ramp-out controls the exit transition.
For the KING starting tables:
- Neolith ramp-in and ramp-out are 75% of feed.
- Dekton ramp-in and ramp-out are 50% of feed.
Confirm how the individual machine controller interprets these fields.
Always confirm the machine’s units
Some saws use meters per minute, others use millimeters per minute, and others use inches per minute.
Use this conversion:
Meters per minute × 39.3701 = inches per minute
Examples:
- 0.1 m/min = 3.94 in/min
- 1.0 m/min = 39.37 in/min
- 2.5 m/min = 98.43 in/min
- 4.5 m/min = 177.17 in/min
Confusing m/min, mm/min, and in/min can produce a dangerously incorrect command.

How the 14-inch KING settings differ
The 14-inch KING starting values are 10% lower than the corresponding 16- and 18-inch values:
- Starting RPM: 2,250
- Starting plunge: 0.09 m/min (3.54 in/min)
- Feed and ramp values: 90% of the corresponding table value
For example, a 6 mm Neolith straight-cut starting feed becomes 4.05 m/min (159.45 in/min), with a 3.0375 m/min (119.59 in/min) ramp.

What about other sintered-stone brands?
For Porcelanosa XTONE, Laminam, Lapitec, Atlas Plan, Florim, Infinity, SapienStone, and similar large-format sintered products, begin at approximately 80%–90% of the applicable Neolith or Dekton benchmark.
Choose the benchmark according to actual material behavior, not brand recognition alone. Test conservatively on scrap and change one parameter at a time.
Do not assume every color, finish, thickness, reinforcement, or material lot will cut identically.
What about a manual bridge saw?
The digital tables are not automatic presets for a manually controlled bridge saw.
For manual bridge-saw work, begin by testing feed at approximately 50%–70% of the corresponding digital feed. This reduction applies to forward feed; it is not permission to exceed the blade’s RPM marking or any machine limit.
The operator must control entry, pressure, water delivery, slab support, and exit consistently.
Do not apply KING settings to every blade
Other E-VDS blade families have their own operating ranges:
- SafetyKut Silent, 16-inch / 400 mm: 2,200–2,600 RPM
- SafetyKut Silent, 18-inch / 450 mm: 2,000–2,200 RPM
- V-ARRAY, 14-inch / 350 mm: 2,000–2,600 RPM
- V-ARRAY, 16-inch / 400 mm: 1,800–2,400 RPM
- THE QUEEN, 16-inch / 400 mm: 1,500–1,800 RPM
- THE QUEEN at 20 mm: 1.2 m/min (47.24 in/min) feed
- THE QUEEN at 30 mm: 0.8 m/min (31.50 in/min) feed
The X-TURBO is a different 125 mm porcelain cutting and roughing disc. Do not assign it a bridge-saw RPM based on diameter alone.
A repeatable tuning process
Before changing parameters:
- Confirm the exact blade, material, thickness, arbor, and saw.
- Verify the controller’s active units.
- Inspect blade condition, flanges, runout, alignment, support, and water delivery.
- Enter a conservative starting point.
- Make a test cut on matching scrap.
- Change one parameter at a time.
- Record RPM, feed, plunge, ramp, water, support, finish, noise, and vibration.
- Stop immediately if the blade wobbles, wanders, overheats, or sounds abnormal.
