WHAT IS LEGACY ENGINEERING?

When you find the right solution, you stick with it. If a motion control is the very best, you should use it on everything you build.

We utilize the very best Technologies throughout our entire product line ranging from Aerospace to Stone machines.

 

WHY DOES NORTHWOOD USE FANUC CNC & SERVO MOTION CONTROLS?

Do your research!

Many machine companies in the stone industry don't choose the very best motion controls for one simple reason: COST!

Fanuc Motion Controls cost more, and they cost more for a reason. They are the industry leader in motion controls. When large aerospace, machining, or industrial companies need dependable accuracy, they specify Fanuc. They are the only control company offering a 25 year commitment to support their controls.

At Northwood we take pride in only using the very best components available to build our machines. These strategic choices have a long term ROI that benefits you. Years after you have paid for your machine, it will continue to reliably perform and make you money.

 

WHAT IS FINITE ELEMENT ANALYSIS?

FEA Technology

stone/fea.jpgThe rapid advance of Computer Aided Engineering (CAE) techniques and software have lead to a virtual revolution in companies that continue to invest in the latest in high-speed computers and computational software for analyzing parts and assemblies. One of the most important components of CAE that Northwood uses is Finite Element Analysis (FEA), a detailed mathematical computer simulation that enables engineers and designers to develop products more quickly and completely that traditional prototyping methods allowed. FEA makes it possible for specific machine components to be targeted for in-depth analysis to eliminate failure from fatigue rather than waiting for those components to begin failing (sometimes years into a product's lifecycle).

FEA tools also provide visual verification of both the element meshing (for integrated calculations) and for the locations of resulting data for large, complex structures or for small, single parts. In this process, geometries are broken down into elements, and each element is meshed, with each mesh connecting at points called nodes according to various model parameters and analysis type. The byproduct is an accurate simulation and prediction of various physical effects such as stress, strain, deformation, vibration, etc. This means that you can expect your Northwood machine to be rigid, quiet, strong, and long lasting. Combined with good result estimation practices and error checking, FEA is an invaluable tool for the modern manufacturer.

WHY USE PRECISION GROUND BALLSCREW & CAST IRON INTEGRATED DRIVE?

Precision Ground Ballscrew

The ballscrew systems that Northwood has chosen are proven to produce the needed accuracy long into the future.  The ballscrews are driven directly through the FANUC servo motors using both turning nut and turning screw methods depending on the application. Northwood also protects the ballscrew with heavy-duty bellow systems to ensure reliability.

Cast Iron Integrated Drive

Northwood has developed an integrated cast-iron drive casting that houses the FANUC servo and the ground ballnut to allow for precision alignment of the servo and turning ball nut.

WHAT IS A PRECISION LINEAR GUIDE RAIL SYSTEM?

Linear Guide Rail System

When you choose a Northwood, you are choosing a machine with the very best components. Our stone machines use special corrosion resistant lineal guide rails from THK. They are the best money can buy.

Our commitment to top-tier technology insures your investment will keep performing for you long after your machine is paid for.

That is the Northwood Way.
