SPINDLE ACCESSORIES AND SUPPORT EQUIPMENT

GMN USA offers a wide range of spindle support equipment including oil/air lubricators, coolant chillers, spindle drives, assemblies and other accessories.

Our engineers will calculate the spindle support requirements for both new and retrofit applications.

LUBRICATORS

The electronically controlled lubrication unit PRELUB is optimally adapted to the oil-air lubricated GMN spindles and guarantees a long service life. The precisely controllable lubricant dosing ensures effective bearing lubrication as well as maximum operating security during the start and shut-down phases. With a maximum of 4 connections, the lubrication unit offers concomitant, individual provision to a maximum of two spindles, and takes up very little room. The connection opportunities to commercial personal computers provides an overview of operation with a multi-language menu structure.

CABLE ASSEMBLIES AND CONNECTORS

GMN supplies towed chain UL and CSA-approved electrical cables for the electrical spindle-to-inverter connection. The wire lengths must be limited in order to achieve the statutorily prescribed electromagnetic tolerance. The appropriate EMC rules and guidelines must be adhered to in layout and commissioning. GMN high-speed spindles are equipped atrated current with different connectors – Flange sockets and plugs. On request, preassembled cables with B048-, B049-, GA-, MAC-, D500- and STK plugs are available.

PROPER ACCESSORIES

The functionality, effectiveness and lifetime of your spindle
can be increased with the proper accessories.

SPINDLE AND TOOLING ACCESSORIES

Grinding quills for standard tool interfaces GMN manufacturers grinding quills with high roundness and flatness precision for nearly all provided GMN standard interfaces.

  • GMN grinding quill wheel for interfaces D14 / 23 … D36 / 68; Right turn versions are available at short notice
  • Further dimensions and direction of rotation left on request

GMN semi-finished products allow the individual adaptation of the tool interface for any connections.

CHILLERS

The reliable availability of the required coolant quantity and temperature reduces the heat generation caused by the operation and ensures maximum detachable spindle speeds. GMN chillers ensure precisely adjustable temperature and quantity delivery of the cooling medium and achieve consistently low operating temperatures. High-precision control accuracy reduces axial shaft misalignment, caused by temperature fluctuations in the coolant.

DRIVES

GMN motor spindles are operated by means of inverters in an uncontrolled or controlled manner, each with a speed sensor (RPM sensor) or a rotary encoder. GMN offers three different types of drive systems:

  • Drives without controllers: Frequency control with provision of voltagefrom the U/F characteristics
  • Drives with controllers: Field-oriented control
  • Drives with controllers: Field-oriented control with c-axis operation rotary encoder
