| Shoda's
dedication to superior design and construction is what sets us apart
from the crowd. |
Other
manufacturers often cut corners, using sheet metal and plastics in
their machine construction.
While this saves money for them, and makes purchase prices lower,
it will cost you more money in the long run. |

Shoda
machines are forged from the highest quality steel and iron alloys
to produce
extremely vibration
resistant machines. This saves
time and money in terms of: |
|
|
|
|
|
|
|
|
|
|
|
•Parts
accuracy
•Spindle, bearings, and tool wear
•General machine maintenance and wear
|
|
|
|
|
All
of this equates to less downtime, more usable parts, and more profit
return on your Shoda machine investment.

| Depending
on the purpose of the component, the method of construction used is
either iron allow castings
or steel weldments. |
|
|
|
|
|
|
|
Portions
of the machine subject to vibration are made from castings.
A casting is less consistent in mechanical properties (variable
hardness and density)
and tends to absorb vibration. |
|
|
|
|
|
|
| Portions
of the machine requiring dimensional stability (i.e. the machine
frame) are made of steel weldments |

Machine
Base:
The machine base is a steel weldment using up to a 1.25"
steel plate. It is computer-designed specifically to absorb
vibration and maintain structural integrity.
The entire base is a single piece, machined in a single set-up,
to ensure accuracy and trueness; not just
tubes welded together.
No shims are used on Shoda machines. |

Machine
Bridge:
The bridge is one of the true strengths of a Shoda machine.
The bridge's internal bracing guarantees vibration-free machining,
allowing faster feed rates and higher quality finishes.
Shoda holds several patents for the bridge
design. |

Ballscrew:
This component is certified machine-tool grade, machined of
highly rigid molybdenum steel, carbonized, hardened, then precision
ground.
For added accuracy and stability, ball screws are extra-large,
making them the most accurate in the CNC industry.
In
concert with anti-backlash ball nuts, the machine repeats t
+/-.003". |

Tool
Carrier:
The tool carrier is a precisely engineered casting with a high
strength-to-weight ratio to which the spindles are mounted.
It is an internally ribbed, double-walled construction to further
augment a casting's inherent vibration absorbing properties.
The tool carrier is an example of continuous
refinement of a component for more than 20 years. |
