Manufacturing Philosophy
All of the Live Tools are manufactured in our plant in Turin, Italy.
We ensure the best possible quality by using the most modern and advanced manufacturing machines available. The bodies of our Live Tools are machined from a solid block of steel. This monoblock construction avoids the vibration and structural defects caused by welded or bolted bodies. Each Live Tool is thoroughly tested after assembly to ensure proper operating characteristics.

Modular Concept
The modular concept used to design and build our Live Tools allows us to offer:
  • Superior quality
  • Extended LT range available with internal or external coolant
  • Quick deliveries
  • Competitive price

Patented Drive Transmission
The drive transmission is the real "heart" of the Live Tool.
During the initial design of the Live Tools, we analyzed the different drive systems available on the market. We finally decided to design and patent a special and innovative drive system offering reliability and durability.
Our competition uses a drive key on the outside of the shaft and inside of the gear, generating a tangential (indirect) transmission.
The possible consequences of this system are: weakening of the shaft and the gear; low torque transmission; vibration, breakage of keys and shafts.
Our patented, SUPERCOMPACT drive system is able to eliminate all of the above described problems.
The ground shaft and the gear are mated in a single operation, in a square or hexagonal union.
All surfaces including the centering diameter are ground.



Bevel Gears Features
Our angular Live Tools use bevel gears with a helical tooth form.
These gears are ID and OD ground, allowing a very precise mating, higher torque and reduced heating of the tool. Possible backlash between the bevel gears is minimized during the mating of the gears and tool assembly.
This enables vibration free operation.
The bevel gears in our Live Tools have a larger circular pitch dimension compared to the gears used by our competitors. The teeth of our bevel gears are hardened to a depth of 0.6/0.8 mm (0.24"/0.31").
Internal components are made of special steel, case-hardened and ground.



Bearing Features
After careful analysis, the bearings we use have been chosen specifically for our Live Tools.
They are sealed on one side only, to exchange heat and lubrication; the two bearings operate in the Live Tool as a single bearing.



Patented Sealing
Our Live Tools are fully "sealed" using special "labyrinth" seals.
The two seals sit between the tool body and the rotating shaft, one located near the rotating shaft, the other one is inside preventing the entry of dirt chips and fluid and providing a long life for the bevel gears and bearings.
This is the "added value" we design into our Live Tools to deliver sturdiness, quality and durability to our customers.



Test Stand & Quality Certificate
Each tool is tested at maximum rpm for 1 hour to guarantee durability and once the durability test is completed, the Live Tool has new lubrication added and an additional test at maximum speed is performed to check following values:
Geometric dimensions - temperature - noise and vibration.
The test report for each Live Tool is included in the box with that tool. This procedure assures the maximum traceability of the processes and the total quality certification of our products.



Warming Up the Live Tools
For the correct use of our Live Tools at maximum speed, we recommend a run up period of 40 second at 500 rpm.



Packaging
The packaging of our Live Tool has been developed to facilitate easy and quick identification by the operators and to avoid the error of shipping the wrong tool.
On the outside of every box there is a short description, a picture and a bar code label. In addition to the use and maintenance manual, inside every box is a wrench kit for proper.
Live Tool use and in the angular tool box also a greasing kit. Inside every shell-mill box is a set of spacers and mounting accessories.
