Introducing the NF-Series Brushless Electric Torque Screwdrivers
Mountz E-DRIV ESD Electric Torque Screwdrivers Save Money and Improve Quality
San Jose, Calif., - Mountz, Inc. introduces the NF-Series, a new line of brushless electric torque screwdrivers as the premier assembly tool in the Mountz E-DRIV brand of power tool products. Designed for high production environments, the E-DRIV NF-Series feature a high performance brushless motor design that provides durability and reduces the standard maintenance costs for electric screwdrivers. Additionally, costly mechanical micro switches have been eliminated in the NF series in favor of non-contact magnetic sensors.
In addition to lower maintenance costs, the NF tool is ESD certified, ensuring less than 1 Ohm at the bit tip. ESD management in power tools ensures product quality, cost savings and a reduction in overall ESD failures. Manufacturing engineers involved with microelectronic products are aware of the importance of controlling Electrostatic Discharge (ESD) failures. Lapses in preventing the occurrence of electrostatic discharge can affect production yields, manufacturing costs, product quality, product reliability, reputation and profitability.
Static damage to electronic components can be realized as catastrophic or latent failures. Catastrophic failures are easier to detect and resolve. With this type of failure the part is "dead" and will not function. It may be costly to repair but is easy to manage. With latent failures the problem is much worse as the failure may not be detected in testing but is a "time bomb" waiting to happen. Since this product will get into the field and cause intermittent problems or failure in the field, it can be a much more costly problem.
The NF-Series features an Over Heat Protection (OHP) and Over Current Protection (OCP) that protects the electric screwdriver from damage or malfunction. The temperature detection powers down the unit and resets automatically when unit restores to acceptable levels. The NF-Series is designed with a LED display that signals the tool's status for the operator to clearly view.
The benefits of the versatile NF-Series are available in three styles for a variety of assembly applications.
The different styles of the brushless electric screwdrivers provide manufacturers flexibility and ability to select the proper tool for their application. The standard NF-Series models are available in "Push-to-Start" or "Lever-Start" configuration with various models covering a torque range of 2.6 to 39 inch-pounds. The power tool features a built-in adjustable speed control, which allows an operator the ability to adjust the RPM directly on the tool.
Mountz offers a NF-Series "Plus" model that features a selectable Double Hit Mode for soft joint applications and a selectable Soft Start mode. When an electric screwdriver runs down a fastener and the tool clutches off once the preset torque is achieved there can be some joint relaxation that can occur. Joint relaxation is caused by the surface of part(s) embedding or by "soft parts" such as gaskets, plastics or spongy material, which collapses under the clamping force created in a torque condition. The clutch of the NF-Series "Plus" electric screwdriver works twice at the set torque under the "Double Hit" mode. The Double Hit will increase the repeatability accuracy at the target torque by double-checking. The "Soft Start" mode is for applications that require the power tool to slowly ramp-up to its operating speed, perfect for plastic or sensitive applications. There are 3 different time settings for the Soft Start mode, which are (0.2, 0.4 & 0.6 seconds).
There is an additional "Time Control and Auto Reverse" model that allows the operator the ability to set the start, stop and operating direction of the brushless electric screwdriver. This power tool model is ideal for installation of helically wound inserts, light tapping or gauging applications.
Controlling torque is quintessential for companies to ensure their product's quality, safety and reliability isn't compromised. The failure of a three-cent fastener that isn't properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose and excessive torque can strip threaded fasteners. Mountz electric torque screwdrivers are designed for precision torque control and have become the state-of-the-art in innovative assembly. Using a quality electric screwdriver has become increasingly important for many companies to ensure that proper torque is being applied and maintains gauge requirements associated with the ISO 9001 Quality Standard.
