Machine Design

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.

MachineBridge:
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.
