The CHP ATX intelligent screwdriver is equipped with a nonslip grip, a high-quality DC brushless servomotor, a high-precision transducer, and a high-resolution digital encoder for accurate angle measurement. The tools are accurate to within ±3 percent of the set torque value.
The screwdrivers have an LED status indicator ring and a 1/4-inch hex bit. Model ATX-12 has a maximum speed of 2,000 rpm and a torque range of 2.4 to 12 kilogram-centimeters. Model ATX-30 has a maximum speed of 1,200 rpm and a torque range of 6 to 30 kilogram-centimeters. Model ATX-50 has a maximum speed of 700 rpm and a torque range of 10 to 50 kilogram-centimeters. The tools can be programmed for lever start, push to start, or both.
Engineers use a 10-inch, LCD touchscreen digital controller to set torque and speed. The user-friendly controller includes a network interface to store and export graph data. It comes with either one or two ports for powering and controlling the drivers. As a result, two drivers can be operated simultaneously or in a user-defined sequence. Each fastener parameter is programmable for various combinations of time, torque, rotation angle and direction. Programmable digital I/O and definable user profiles with password protection provide process control.

Transducerized Cordless Screwdriver
This programmable, transducerized cordless screwdriver delivers precise torque control. Model DFT060TMZ has a torque range of 2 to 6 newton-meters. Model DFT120TMZ has a torque range of 4 to 12 newton-meters. The tool is equipped with an efficient Makita-built brushless motor, with a no-load speed of 400 to 1,300 rpm. Including the battery, the tool weighs just 2.4 pounds. A built-in LED light illuminates the work surface for better visibility in low-light environments.
The tool automatically shuts off when a preset torque is reached, and it provides both visual and audible feedback on each fastening operation. A USB connection allows for six-stage programming of both direction and speed control throughout the fastening process. The tools are certified for a repeatability of ±4 percent of mean torque.
The tool is powered by a 14.4-volt lithium-ion battery for extended run time and a greater number of lifetime charge cycles. The tool is automatically disabled once battery capacity drops below 5 percent. The battery recharges in only 30 minutes.

Cordless Screwdriver Is Smart
The EPT all-in-one transducerized cordless screwdriver has a built-in sensor that continually measures torque in real-time and feeds data back into the system. An error-proofing system helps prevent defects. Engineers can easily program the tool, setting torque tolerances for each fastener in a sequence. The tool records and stores torque and fastening data. Weighing 4.5 pounds, the tool has a 3/8-inch square drive and a torque range of 11.5 to 57.5 inch-pounds. Driver speed can be adjusted from 100 to 1,250 rpm.
Features include a built-in bar code scanner; digital I/O for interfacing with a machine; a PLC interface for line control monitoring techniques; and a screw counting function to ensure that all screws are accounted for during assembly.
Benchtop System Automates Screwdriving
The BT-001 is a semiautomatic benchtop machine for automating screwdriving operations. It holds the screwdriver and automatically lines up with the part, eliminating the need for an operator to hold the tool. It helps to streamline assembly processes by minimizing operator involvement.
It works with all Sumake electric screwdrivers and can be integrated with screwfeeders. It can handle torque ranging from 0.17 to 309.8 inch-pounds and screw sizes from 0 to 16. Maximum speed is 40 fasteners per minute. One machine can be adapted to multiple screwdrivers. A puck is included to hold the assembly.
