FullSharp built a 500 kg rail frame from the rim rack to the CNC machine door with a dedicated wheel rim clamp, for heavy, round rims that two workers used to carry and set down at each fixture change. The clamp grips the rim edge, the trolley carries it to the spindle and lowers it into the fixture, so one worker does it all.

Wheel rims are heavy, round and slippery, so carrying them by hand is hard to control, and setting them down on the machine table risks hitting the chuck and damaging the machined face. Every fixture change needs two workers, and the CNC machine has to sit idle waiting, dragging down output for the whole line.

FullSharp built a 500 kg rail frame system running from the rim rack to the machine door, fitted with a dedicated wheel rim clamp tool. The clamp grips the rim edge, the trolley carries the rim to the machine spindle, then lowers it into the fixture — one worker handles the whole operation.

500 kg Rail Frame System with Wheel Rim Clamp Tool for CNC Loading

500 kg rail frame with wheel rim clamp tool loading a rim into the CNC machine.

Equipment Installed

  • 500 kg rail frame: load-bearing steel frame with a rail running from the material rack to the CNC machine door.
  • Wheel rim clamp tool: jaws grip the rim edge, keeping the rim balanced during lifting and positioning.
  • Lifting unit: lowers the rim onto the chuck slowly, giving the operator time to center it before clamping.
  • Rail trolley: pushed by hand along the line, carrying the rim from the rack to the machine without an intermediate cart.
  • Rail end stops: limit travel at both ends, keeping the trolley within the working zone.

Benefits for the Plant

Less machine downtime

Faster, more consistent fixture changes reduce idle time on the CNC machine between machining runs.

Rim faces stay flawless

The rim is clamped and lowered under control, avoiding impacts with the chuck or machine table.

One worker per fixture

The clamp tool replaces a two-person carrying job, letting the machine operator load fixtures alone.

Suitable Applications

  • Wheel rim and tire machining shops
  • Machine shops fixturing round parts onto CNC machines
  • Fixture-change stations for lathes and milling machines
  • Material stores handling heavy disc-shaped parts

Frequently asked questions

How do you load wheel rims into a CNC machine?

Use a rim clamp on a rail or crane that runs to the machine door. The clamp holds the rim edge and the operator lowers it into the fixture without hitting the chuck or the machined face.

How much does this rail frame carry?

The frame in this project is rated at 500 kg. FullSharp sizes the frame and route from the rim rack to the machine door during the survey.

How does this improve output?

Fixture changes no longer need two workers, and the machine waits less between parts, so the whole line runs closer to its real capacity.

Installation Consultation for Your Plant

FullSharp measures the rim diameter, thickness and weight, checks the CNC spindle height and the distance from the material rack to the machine. Based on that, we design the clamp jaws to fit the rim edge and set the rail route. Call FullSharp to schedule a site survey.
