There are many details regarding the processing and production of stone materials. Below we have some parameters and guidelines for you to consider.
What you'll need:
ISO 40 cones (hold tooling, bits, and wheels)
Calibrating wheel (evens out the surface)
Profile tool set (7 wheels - 4 stone, 3 resin polishing)
Profile sets cost $2,000 - $3,500
Profile sizes: 60mm or 120mm diameter
Profile heights: 2cm, 3cm, or 4cm
Each set consists of:
4 diamond bits and 3 polishing bits
Regular speed or hyper speed sets are available
Tool Durability / Life span:
Some expected guidelines are below regarding durability/life span:
#1 Diamond tool: 4,000 - 6,000 linear feet
#2 Diamond tool: 12,000 - 16,000 linear feet
#3 Diamond tool: 12,000 - 16,000 linear feet
#4 Diamond tool: 12,000 - 16,000 linear feet
#5 Polishing tool: 1,000 - 1,500 linear feet
#6 Polishing tool: 1,000 - 1,500 linear feet
#7 Polishing tool: 1,000 - 1,500 linear feet
Finger bits last approximately 300 - 600 linear feet
Core bits last for 200 - 300 holes
Variations in wear are the result of how much material the bit is required to remove as well as differences in bit density. The lifespan of the #1 diamond tool can be extended by dressing the wheel periodically. This in turn extends the life of all the other bits as well.
Fresh water is required for inside the spindle.
Recycled water can be used for outside the spindle.
Water use: Approx. 5-7 gallons per minute total usage. Fresh water requirement is about 10% of this amount. With recycling the water, figure about 200 - 300 gallons per day of fresh water use with 8 hours of consistent machine use and a good recycling system.
Water recycling - there are two main ports that face towards the back of the machine to drain the water. A variety of water recycling systems can be employed to reduce water usage. We have some very compact and powerful water cleaning (solids removal) and recycling systems available here at Eagle Rock. If you need a system to clean large amounts of water quickly, check out the Eagle Rock Aqua line here.

Manual vs. CNC comparison
The following information has been gathered from a number of sources. These numbers can be used to make a reasonable estimation of cost savings from automated CNC equipment versus manual fabrication.
Tooling cost per lineal foot: $3.00
Approximate production labor cost is calculated at $15 per hour with a 3 foot per hour production
=$5 manual labor cost per lineal foot
TOTAL manual cost=$3 + $5=$8 per lineal foot
Manual cost: $8-$9 per lineal foot
Tooling cost per lineal foot: $1.00 (wheels and bits)
Approximate production cost with a machine operator paid at $20 per hour with a 15 foot per hour production rate=$1.33 CNC cost per lineal foot
TOTAL CNC cost=$1 + $1.33=$2.33 per lineal foot
CNC cost: $2.33 per lineal foot
