Unist The Mini-Piggyback™ System
The Mini-Piggyback™ system sets a new standard for lubricating cutting tools on positive feed drills. This system uses a positive displacement pump to precisely apply the right amount of lubrication to the cutting tool, hole after hole.
The Unist Mini-Piggyback™ system sets a new standard for lubricating cutting tools on positive feed drills. This system uses a positive displacement pump to precisely apply the right amount of lubrication to the cutting tool, hole after hole. The operator can easily adjust both the fluid and the air output to “dial-in” the perfect setting for any tool.
The Mini-Piggyback™ is 100% pneumatically operated. It is designed to use air supplied “downstream” from the tool trigger, so it operates whenever the tool is running. The fluid supply is contained in a removable reservoir that can easily be exchanged when empty. Empty reservoirs can be refilled using the Unist reservoir refill stations, so they’re ready to use again. The lubricant may also be supplied from a remote gravity-feed or pressurized reservoir. The Mini-Piggyback™ can dispense a wide range of lubricants with varying viscosities. Atomizing air can be easily adjusted or turned off completely.
The Mini-Piggyback™ is available in two configurations: continuous output, which provides a constant delivery of lubricant for operations with long cycle times, and intermittent-output, which provides a single shot of lubricant for smaller cutting tools with short cycle times.
Stay productive with Mini-Piggyback™
The automatic and manual Mini-Piggyback™ reservoir refill stations are designed to allow swift and easy refilling of quick-change Mini-Piggyback™ reservoirs. The stations fill Mini-Piggyback™ reservoirs and virtually eliminate trapped air which can cause inconsistent fluid output. Using these stations ensures properly filled reservoirs every time.
A unique feature of the Mini-Piggyback™ system is the removable, interchangeable fluid reservoir. This allows the lubricant to be replenished almost instantly by simply replacing the empty reservoir with a full one, maximizing the productivity of the tool.
