DF Cam Indexers

DF Cam Indexers, also known as Flange Output Cam Indexers, are advanced precision indexing tables that facilitate the precise starting and stopping of devices at specific intervals. These indexers are specially designed to connect turntables or discs directly to the flange, eliminating the need for additional connection parts.

A Flange Output Cam Indexer uses a double-flange disc cam with twin conjugate groove faces to drive an output turret through precise intermittent rotation. The dual-flange geometry straddles the roller turret from both sides, distributing the contact load across two cam surfaces simultaneously. This configuration doubles the effective load-carrying area compared to a single-disc DS unit, raising the allowable output torque and radial load capacity without increasing the housing diameter. During dwell, both groove faces lock the turret rollers in position, holding output repeatability within ±8 arc-seconds.

Electronics: PCB press-fit insertion — 6-station indexing nest

A Flange Output Cam Indexer positions PCB carrier nests under a 35 kN press-fit head that drives connector housings into plated through-holes. The vertical press force transmits a 1.8 kN·m tilting moment to the output flange on each cycle. The DF double-flange structure resists this tilt without deflecting the nest beyond 0.015 mm, maintaining pin-to-hole registration within ±0.05 mm across all six stations. Cycle rate runs at 25 indexes per minute with a 270°/90° dwell-to-index ratio, giving the press head 2.2 seconds of stationary dwell per cycle.

Food Processing: Canning line — 12-station fill and seal turret

A sealed grease-packed DF cam indexer drives a stainless-steel 12-station turret in a high-humidity canning environment. Each station holds a 750 ml can under a fill nozzle, then a seaming head. The turret plate weighs 60 kg and carries asymmetric can loads that shift the center of mass 180 mm from the shaft. Flange Output Cam Indexer runs at 120 indexes per minute with oil-free sealed lubrication, meeting IP65 washdown requirements. Output repeatability of ±8 arc-seconds positions each can within ±0.3 mm of the seaming head centerline.

12 stations / 30° index                        Input: 120 RPM                    IP65 sealed grease                Dwell ratio: 180°/180°

Medical Devices: Syringe barrel assembly — 16-station rotary dial

A DF cam indexer drives a 16-station dial plate in a Class 7 cleanroom assembling syringe barrels, plunger rods, and tip caps. The sealed DF unit runs on food-grade grease with no oil mist output, meeting ISO 14644-1 particulate limits. Each station indexes 22.5° at 60 cycles per minute. The DF dual-flange lock holds each barrel nest within ±8 arc-seconds during laser inspection at station 14, where a vision system measures plunger travel to ±0.02 mm. No secondary registration pin is needed at the inspection station.
