"Produce quality parts more competitively and profitably with the machine that is fast, reliable and highly affordable"

SERVO IMPACT System 2...

Invaluable in reducing machine overhead and production costs. Saves valuable floor space. Quickly machine parts that fit a work envelope of 10" x 5-1/4 x 3-1/2 ".

Low Investment

With a base price under $15,000, the IMPACT System 2 easily accommodates those with a limited budget. Plus with the option of low monthly lease financing, the IMPACT System 2 offers even greater affordability.

Compact Size

Requiring just six square feet of floor space, the IMPACT System 2 is ideal for confined areas. It can save as much as thirty square feet of space compared to full-size CNC footprints.

Lower Operating Costs

Would you like to reduce equipment overhead costs dramatically while better utilizing your full-size CNC to machine larger parts? Our comparison, below, illustrates how the cost to produce a single part can be reduced by 85% or $4.08 per part using the IMPACT system 2 ! (And this doesn't even address lower tooling or labor costs. ) Could this be the cost-reduction factor that will make you more competitive?

Cost comparison reveals how you can save 85% or $4.08 per part with the IMPACT System 2!

From highly inefficient... Your full-size "$100,000" CNC is in use 40 hours per week. Over five years (10,400 hours), your machine overhead costs $9.61 per hour. Operating costs to machine a 30-minute part run $4.80 per part.

$100,000/10,400 hrs. = $9.61 per hr / 30 min = $4.80 per part

To highly efficient... You purchase a "$15,000" IMPACT System 2 instead. With the same amount of use and amortized over the same time period, your operating costs drop to only $1.44 per hour. Machining the same 30-minute part above, your overhead costs decrease to just $.72 per part.

$15,000/10,400 hrs. = $1.44 per hr /30 min = $. 72 per part ($4.80- $.72 = $4.08 per part savings)

System Flexibility

Use Servo's control software to discover the ease and flexibility of designing and modifying part designs on your PC. Obtain the proper size and shape of your part with features such as scaling and mirror imaging. Tilt, compress and stretch your designs using your favorite CAD/CAM software. Even Input scanned line art. Create part programs of any length. Then, using the PC or pendant to control operation of the Servo mini-mill, quickly create 3D engineering prototypes or production parts. Mill, drill and engrave metals, plastics, green ceramics, wood, glass or wax. Also use the pendant to teach point-to-point and angular moves, and to replay programs.

Impact II mounted on optional bench High resolution mill with VR servo motors helps you save time and
effort with simple setups and low-cost tools and fixtures.

Use inch or metric to make shapes requiring 3 or 4 axes at the same time. Cut full circles with one command. Program your part edge, then specify cutter size. (PC not included.)

Options include fourth-axis rotary table, precision ground ball screws,
workbench including assembled mill/control, plus dual mill heads. PC screen showing axis positions.

Feed rates, feed rate override, program codes and each axis
position are shown on PC screen as part is being machined

Speed and Accuracy

The closed loop servo drive system with encoders (instead of open loop stepper-driven system) offers high resolution with fast feed rates, positioning reliability and shorter cycle times. With these features, the IMPACT mill can outperform some larger, more expensive NC machines, to produce smooth, accurate and distortion-free parts! For even higher performance, spindles with quick change tools, higher horsepower and speeds to 120,000 rpm can be added. Impact II shown with Optional dual head bracket.

Reliability

What's more, the brushless DC variable reluctance servo motors with sealed motor covers mean less stringent maintenance, longer motor life and quieter operation.

Use two heads to make two identical parts at one time, or load a 
different tool in each spindle for multiple operations on one part.
