Why Pulsing Tools Will Revolutionize DC Tooling Landscape

Using direct drive DC tools, the maximum reaction forces an operator can withstand are +/-7Nm for pistol nut runners and +/-40Nm for angle nut runners. Above these torque values, expensive and cumbersome manipulators are needed to absorb the reaction forces.

 

Thanks to ESTIC’s patented motor control system, the pulse fastening technology using their DC tools has achieved an unprecedented reduction in reaction forces for the operator. By tightening using intermittent impact force like hitting with a hammer, users receive little reaction force compared to tightening by continuous motion where users receive a large reaction force which is shown in following video:

ESTIC - Patented Pulsing Technology

The patented “Estic Pulse” technology reduces the reaction force when fastening to a minimum and promotes safety. This ergonomic technology reduces the risk of workplace injury. What’s more, the tool’s ergonomic design and advanced pulse fastening technology allow for single-handed operation in certain situations, dramatically reducing the strain placed on the operator.

Corded or cordless handheld electric DC nut runners with pulse technology are available in following models:

This series corded or cordless DC tools including some high speed tools as following examples:

  1. a 30 Nm corded pistol tool has a programmable free speed up to 3075 rpm
  2. a 100 Nm corded angle tool has a programmable free speed up to 1125 rpm

The tool performance of Estic electric DC pulse tools is tested with the equipment compliant with ISO5393 and fastening accuracy 3σ/x̄  ≤ ±3%.

Cordless nut runners are equipped with ESTIC’s patented pulse tightening technology, so work can be done with minimal reaction to the operator. The ESTIC cordless tools can fasten up to 100N・m.

 

01 Pulse Fastening
By tightening using intermittent impact force like hitting with a hammer, users receive little reaction force.

 

02 Direct Fastening
Tightening by continuous motion, users receive a large reaction force.
