We provide all manufacturing, including testing, and ship qualified subassemblies to your facility. Custom motors and bearing assemblies are a specialty. We can also provide unique castings, weldments, and frames with installed and tested motion systems.

Invetech, of which Dover Motion is a division, has personnel located in Southern California. Invetech’s North American offices are located at 9980 Huennekens Street in San Diego, CA.

Dover Motion is located at 159 Swanson Road in Boxborough, Massachusetts, USA. All of our products are manufactured at our Boxborough facility.

Dover Motion is a division of Invetech, an industry leading product realization company that helps customers develop new products from concept through to manufacture. Dover Motion leverages its fifty-year history and is focused on providing standard products and custom engineered assemblies to clients needing motion solutions.

Yes, in 1999 Kollmorgen Corporation agreed to purchase New England Affiliated Technologies (NEAT) of Lawrence, Massachusetts. The business was then moved to Salem, New Hampshire. In 2002, Dover Instrument Corporation of Westborough, Massachusetts was acquired and combined with the NEAT. Today both businesses are under the Dover Motion brand name with onsite design and manufacturing in Boxborough, Massachusetts.

Our Products

Dover solders are lead free and our products, components, or systems can be RoHS compliant if required by our clients.

RoHS

The Restriction of Hazardous Substances (RoHS) Directive limits the usage of hazardous materials in the manufacturing of various types of electronic components. The RoHS Directive is enforced in all the European Union Member States and all products must undergo periodic compliance checks.

REACH

The Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Act is a set of European Union Regulations that address the production and usage of chemical substances in manufacturing.  REACH is considered one of the most complex pieces of legislation passed by the European Union and all companies operating within their territory are strongly encouraged to comply.

Yes, we have 2 standard product air bearing stages: our Airglide™ air bearing stage and the FiberBeam™ low-profile linear air bearing stage.

Yes, we repair most of the old N.E.A.T product line.

You can find our service and support reference library for installation manuals under the Resources tab of this website, or here.

Yes, our controllers have LabVIEW capability, but we do not support LabVIEW applications unless designed specifically for your project. Please contact us for more information on sample LabVIEW libraries.

Dover Motion can provide various levels of support on all products. For further details please contact us.

Technical Questions

Dover gantry stages are designed to provide unsurpassed repeatability and excellent throughput under real world operating conditions. Our gantry stages are designed to move such items as inspection cameras, laser heads, or specific customer tooling over either removable substrates or fixtures mounted to the base of the system. The gantry base can be provided with mounting holes for interfacing a customer’s hardware to the stage. Due to its simplicity and ease of assembly, it is the ideal gantry stage configuration for OEMs and system integrators building machines for demanding applications. Many of Dover Motion’s standard screw driven and servo motor linear products can be integrated together as a gantry stage to achieve an application’s required accuracy and travel for XYZ motion.

  • Pre-formatted base for ease of integration
  • Risers to provide space between the base and moving beam
  • Integrated cable tracks and hi flex cable
  • All axes tested together and burned in to ensure performance and reliability requirements are met before shipment

gantry-stage
The example shown above is run by stepper motors and controlled by the Dover Motion multi-axis stepper controller. Incorporating linear encoder feedback and cabling, it achieves 15 to 300 millimeters of XYZ linear motion travel.

Popular applications for gantry stages include:

  • 3D metrology
  • Inspection
  • Probing
  • Pick and place
  • Laser machining
  • Laser scribing and marking

Dover controllers and external cabling are available to create a complete turn-key motion system for gantries. Our controllers have coordinated motion capabilities for accurate multi-axis lines, arcs, and circles. Optional rotary or linear encoders are available to improve accuracy and repeatability. For the most accurate positioning requirements, two-point and multi-point compensation can be programmed for each axis. Dover Motion’s control options include an intuitive user interface and three-axis joysticks are available for control of the XYZ axes.

Unfortunately, this varies by customer. If you are requesting any specific information on your stage or system, please have the serial number available when you call or email. Examples could be lead screw pitch, stage travel, limit type, and stepper or servo motor.

Our standard switches are typically open.

Our standard 23 frame motors are wired so you can run them either way. Please reference the motor wiring pinout for correct connections.

The torque range on a ball screw is set by the ball screw vendor. So it can vary from screw to screw. The main concern is that the torque is consistent through the entire travel of the stage.

No, our standard rotary stage has only 1 limit switch. The switch is typically wired to pin 2 on the limit encoder connector. The limit switch is intended to be used for homing. The homing routine will work with an initial positive or negative jog move of the motorized rotary stage until the limit switch triggers. If an encoder is also used, the home or zero position can then be set at the point where the limit switch is triggered.

The minus limit is the switch closest to the motor end of travel. The positive limit is the furthest from the motor.

The standard torque measured with a Waters Torque Watch should be between 4 and 8 ounces-per-inch.

The type of lubricant used depends on your stage.

  • Lead screws stages: Lubriplate DS-ES
  • Ball screw stages: Shell Alvania Greases EP-LF
  • Recirculating ball mechanical rails: Lubriplate DS-ES
