A preset torque screwdriver is similar to a person setting an alarm clock to signal the achievement of a selected time. The torque screwdriver is pre-set to the required torque value of the application and then the tool signals the operator when torque is achieved. A preset torque screwdriver does not feature an external adjustment scale. These tools have internal adjustment mechanism for setting the torque value and must be preset using a torque tester. Preset screwdrivers are ideal for production applications where there is one torque setting required and you need to prevent incidental or operator tampering of the torque setting. However, if the torque specification changes or new project requires a different torque setting, the preset torque screwdriver is still flexible enough that a new torque setting can be set internally using a torque analyzer.
The cam-over philosophy of each Mountz hand torque screwdriver prevents a fastener or bolt from being under and over tightened. These torque tools ideal are for production applications where over-torque conditions are not tolerated. As a quality control tool, the torque screwdriver allows any user to deliver the correct torque with confidence regardless of task and operator skill level.
The design action of the cam-over torque screwdriver is such that when the tool reaches its preset torque value the mechanism disengages from the drive thus limiting the torque applied. Also, the thrust bearings insure that the torque setting is independent of any end load applied by the operator. Designed for variety of industries like medical, aerospace, semiconductor, electronics, and communications, a Mountz preset torque screwdriver ensures proper torque control. Featuring a tamper-proof internal adjustment, the Mountz preset torque screwdrivers have no external adjustment scale and must be pre-set using a torque tester.
A dial torque wrench is typically used as a quality control instrument to verify or monitor torque. What is a dial wrench? A type of wrench that measures the amount of torque applied to a fastener and displays the torque value on a dial. The dial wrench captures the finishing torque applied to a fastener with a memory pointer.
The versatile dial wrench can be used as an assembly tool for fastening applications or as a quality control tool for joint testing, torque auditing or torque verification. These old reliable tools are suitable for use by operators of any skill level. For fastening applications, an operator can clearly monitor the torque applied. Some dial wrench models feature an audio and visual signal system, which provide a clear indication to the operator when the target torque has been reached. For torque auditing applications, a dial wrench is alternative solution to a digital wrench for conducting a quick visual torque verification test.
Torque Auditing After the Assembly Process Torque measurement is paramount for many manufacturers. Simply running a fastener or bolt down until it’s snug and tight and assuming the torque control process is complete, is no longer sufficient. Measuring torque doesn’t stop once the assembly process is complete. As part of the overall quality control process, manufactures should include a “Torque Auditing” program. A method to detect loose fasteners or any signs of joint relaxation. Torque auditing validates the fastening process, the torque tool, the product design and the materials used for the application.
Thanksgiving is truly and uniquely an American holiday, celebrated with football, family reunions and a smorgasbord of food derived from every part of our country. The variety of turkey preparations and stuffing recipes could fill several cookbooks, maybe libraries and it is likely that Google has already cataloged these for us under easy to search key words.
The richness of this holiday is countered only by the plight of poverty and hunger we find in every community across our great nation and beyond.
As I grow older, I think more than ever about those that suffer. The unsheltered and truly underprivileged or those just down and out on luck enter my thoughts most every day. It’s easy to turn our back on those in need. Thanksgiving is a great opportunity to think about how lucky we are and to reach across the table to those that are truly desperate. To give thanks for what we have and to share with someone who will greatly appreciate it is a wonderful experience. It’s an experience I have come to cherish.
Built for high production environments, FlexPower pulse tools provide durability, power and speed for most industrial assembly applications. To maintain consistent accuracy, the torque output for pulse tools must be verified periodically. You should also validate the actual torque being applied to the fastener by auditing the joint application. The goal for auditing is to verify adequate torque was delivered to the fastener and detect any loose fasteners or joint relaxation.
You need to validate the proper pulse tool is being used for the assembly application. Although a pulse tool has a specified torque range, the type of joint the tool is being utilized on is a key component. A pulse tool is a discontinuous tool and added adapters or extensions create a dampening effect, thus lowering torque values.
Quality and reliability form the foundation upon which new companies build their futures and stake their reputations. As consumers, we are largely unaware of the painstaking pre-production steps and choices that companies make in order to develop products and assure their reliability. One of the most challenging steps that face these fledgling manufacturers is the selection of the tools that they will be depending on to maximize production, guarantee product quality, and assure the productivity and safety of their workers.
Tool selection posed a challenge for a slot machine manufacturer that was developing a new computerized gaming system. The new slot machine contained delicate and sophisticated electronic components. It needed to be built to withstand the rigors of twenty-four hour a day use by enthusiastic gamblers.
Before going into full production, the slot machine manufacturer initiated an extensive prototyping program to establish assembly procedures, and torque specifications using hand torque tools. However, before full production could be started, it had become apparent that more attention was going to have to be given to tool selection with an eye to the issues of productivity, quality and worker comfort.
