Fixed-Station Indexers (TC and TR)
Fixed-Station indexers are driven by a high-precision cylinder cam. The movement pattern is determined by the cam track. The cam takes the constant motion of the motor and transfers it to the dial plate.
The number of stations is determined by the dwell (flat spot on the cam).
- TC indexers offer 2 to 60 positions.
- TR indexers offer 4 to 36 positions.
These units are extremely accurate and offer zero backlash due to the tensioned cam-followers at the stop positions.
Other notable features include:
- Smooth motion profile
- Low maintenance: no oil changes are required and the use of a VFD eliminates brake wear
- Highly accurate & repeatable
- Proximity switch indicates when the unit is in-station
- Sturdy cast iron housing
- Triple bearing of the rotary plates to ensure high loads
- Brake energized to release
- Load tested prior to shipping to make certain the indexer meets your speed and cycle-time requirements
- Mechanics are stronger than motor power: you cannot break the cam followers. This is primarily why Weiss rotary indexing tables do not require an overload clutch. With the Weiss line of
- indexers, you cannot exceed the permitted inertia.
- Compact Design: no external gear box or overload clutch
- Multiple drive positions available
- Multiple mounting positions available
- Stationary centre with through hole
- Side window for cabling
- Special voltage options are available
- Systems come with a PNP prox switch as standard. NPN are available upon request.
- Stationary plate – can mound additional components. All surfaces from the casting to the rotating dial plate to the stationary plate have accurate mounting holes/dowel holes. All the
- customer needs to do is transfer the bolt hole and dowel hole pattern to their mounting plate.
- Motor and pulley housing have a smaller profile than the casting itself, saving the customer the need for costly cut-outs in the machine top plate.
- Clean room modifications are available upon request – EN plating on dial & stationary plates, Steel-It epoxy paint, sealed belt housing, & stainless-steel exposed fasteners
