High Speed Milling Machines are often perceived as luxury items, something costly & beyond a common job shop’s justification.

VIBRA-FREE JS High Speed Milling Machine is introduced to break this stereotype and bring the benefits of High Speed Milling  to American job shops without the typical price tag. To reflect this vision, we name this latest model JS, JS stands for Job Shop.

Vibra-Free JS High Speed Milling Other Features:

Spindle 
From numerous field installation trips, our VIBRA-FREE team realized one way to keep the overall high speed milling cost of ownership down is to have a more versatile spindle. VIBRA-FREE JS is equipped with our time tested 24,000 rpm Swiss made integral motor spindle. It comes with ceramic bearing, intelligent cooling and oil/mist lubrication, keeps thermal growth in check from one shift to the next. HSK 63 pre-balanced, double-face-contact tooling accepts extended tool holders with the rigidity to machine deep cavities. Roughing is no longer a problem with its 40 continuous horsepower spindle offering full torque at 200 RPM.
Bridge Structure 
It is an well known fact that no serious high speed milling can be accomplished on a conventional C-frame vertical machine. VIBRA-FREE JS High Speed Milling features our time tested bridge structure which minimizes overhang and allows optimal weight distribution between base, table and moving ram. Most weight is allotted to the stationary fixed bridge frame, keeping the moving structures light, stubby and rigid.

Integral Motor Spindle
Made to perform on both high speed and low speed end, its 16,000 rpm spindle comes with its own cooling circulation system that maintains thermal stability through entire RPM span. Automatic Hi/Lo speed change make it extra versatile. Practical NBT40 tooling allows one to use existing BT40 tooling, yet also offers secondary nose contact for NBT pre-balanced DFC (double-face-contact) tooling.

FANUC 18i Powered by UHSHM Software
UHSHM software guarantees smooth motion. Before a VIBRA-FREE JS goes out the door, parameters are set for a variety of conditions so one can “change gears” when dealing with different challenges. The world-class Fanuc 18i-MB CNC, advanced AI Nano High Precision contour control (AI Nano HPCC), 1 Gb data server, Ethernet, and rigid tapping are all standard.

Ball Screws and Roller Guides
All ball screws are double end fixed & pretensioned for rigidity.
X,Y and Z guides use roller bearings, known for their high rigidity and excellent damping. See chart below for the comparison between ball bearing guide and roller bearing guide. Roller guide provides the rigidity comparable to that of box square way, yet do not have the typical “stick slip” problem associated with sliding motion.
