Since 1988, Northwood Machine has been innovating solutions to increase productivity and quality. Using technologies and engineering knowledge from all industries, we are constantly developing and testing new methods to build machines based on our customers’ applications. From our own core innovations to the latest in Finite Element Analysis Design, we use advanced technologies to create a custom system for you and your business.
Northwood Core Technologies
American Iron means that each machine starts with thousands of pounds of tubular steel weldment skirted with steel plating. This gives Northwood rigidity and strength that other manufacturers don't supply. Learn more
High-Precision Linear Guide Rail System
Northwood starts with precision machined rail beds before any assembly begins. From there, each rail is verified using high-tech laser metrology. Northwood then applies linear compensation to ensure repeatability and accuracy throughout machine movement.

Service, Support and World Class Training
Due to the modular design of Northwood's equipment, spare parts are readily available from our Louisville, KY facility, located within minutes of the UPS Overnight Headquarters. Our technical support staff is geared towards keeping you productive and solving issues in a quick and courteous fashion. In accordance with our quick-to-production philosophy, training and implementation are completed on-site by our skilled application staff.
All Northwood CNC Machining centers are tested, verified and compensated using a laser interferometer. When necessary, the Faro Tracker is used to verify rotary axes and 3D or volumetric positioning accuracy. Northwood's metrology department also includes high-precision digital levels, precision ground tram bars, wireless Renishaw Ballbar, and indicators that are capable of compensating the machine to provide a high level of accuracy and precision.
3-Axis Advanced Technologies
Northwood's 3-Axis TA CNC Machining Centers start with a single tooling plate and typically one spindle unit. Spindles range up to 22HP liquid-cooled spindles and as many as four (4) on a single tooling plate. Machines can feature multiple tooling plates that allow for dual-processing. Dual-Processing allows for simultaneous machining on separate tables of two different or unique parts.
Besides spindles or routers, Northwood can accommodate just about any other tool needed for any industry. This includes 360-degree programmable saws, horizontal routers, large vertical drilling units (4 line, 19 line, etc), single vertical drills, molder heads, 20HP Fanuc Drive Milling spindle for aluminum and other high-torque, lower RPM applications, as well as many other tools.
Northwood has standard modules of each of these tooling options that can be adapted for any machine. A custom tooling plate or dual-custom tooling plates with independent X (horizontal), Z (vertical), U (horizontal), and W (vertical) axes are commonly available from Northwood.
Since Northwood doesn't just build a single head router, the head configuration can vary greatly on every machine.
Northwood has Automatic Tool Changers that range from 8 positions up to 20 positions. These tool changers can be mounted to the spindle tooling plate to provide dynamic and efficient tool changes or can be mounted to the bridge in a static location. The advantage of the travel along or dynamic tool changer is that tool change cycles are minimized, however for machines with narrow center spacing between multiple spindles, the tool changer increases the minimum spindle spacing. As Northwood understands each industry, they can recommend the best tool changer for your application.
Adjustable Spindle Center Spacing
When a single tooling plate holds multiples spindles, Northwood can provide horizontal axes for adjusting the spindle center spacing. This can be done via a manual center adjustment or via a servo controlled programmable axis via the CNC. Northwood commonly features 4
Northwood Machining Centers Commonly feature cast-aluminum vacuum plenum worktables with high flow for superior part holding. Other options include matrix worktables, flat face milled cast-aluminum worktables for custom fixtures and each cast-iron T-Slot worktables. Whatever the application demands, Northwood has a worktable to accommodate the proper fixture and part holding.
Programmable Part Location Stops
Part location pins or stops are common on all Northwood Moving Table CNC Machining Centers. These allow an operator to quickly locate parts in the X and Y axes to begin machining cycles.

Dual Processing CNC Machine
Dual-processing CNC machines feature dual-worktables and dual-tooling plates that can work independently of each other. This process increases throughout and allows for long set-up times to take place on one side, while the other side of the machine begins its cycle. When the lengthy setup is complete, the operator can begin the cycle on side number 2, without waiting for side number 1 to complete. This is increasingly important the longer the cycle times of the program and the longer the custom fixtures take to set up. Processing two unique or different parts simultaneously makes one machine have
FANUC Driven Milling Spindle
Northwood provides an ISO40 taper Fanuc driven spindle that is capable of rigid tapping in aluminum and other materials. This spindle offering allows the ability to operate tooling with extremely high-torque at low RPMs. This option includes a standard 12 station travel along tool changer in most cases to hold enough tools for multiple parts.

Auto-Unload Material Handling
Automatic Unload Material Handling systems allow for quick unload and faster preparation for the next load cycle. This accomplished by moving the finished part nest onto an off-load machine table via a pushing unit that includes a vacuum dust/chip collection outlet to clean the table and prepare the table for the next sheet. This allows the operator to load the next sheet of material and cycle start the machine before proceeding to the unload table once the machining cycle begins. This process increases throughput and efficiency.
Spindle Mounted C-Axis
A 360-degree programmable C-Axis allows for contouring using this programmable axis and special tooling. It also provides the machine the ability to adapt to many different style aggregates including horizontal drilling units, and adjustable angle saws.
Overhead Laser Projection
Northwood can integrate with an overheard part project laser to help the operator set up the adjust pod fixtures and then load the parts quickly and correctly onto the machine. The laser is capable or accurately projecting where the machine will cut for visual verification that the parts are loaded correctly before the machining cycle begins. This increases throughput as it decreases the load time.

Finite Element Analysis (FEA) Design
The rapid advance of Computer Aided Engineering (CAE) techniques and software
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.
