Identifying and finding the best torque tooling solution for your individual needs is paramount to success in your assembly process. Not all applications require the complexity and investment costs associated with DC tooling for critical fastening. The key in your facility is to obtain knowledge of your assembly processes, problems, ergonomic and safety needs. Repeatability, in process monitoring, durability in harsh or unique environments are just some of the factors that can become part of the equation in fitting your manufacturing team with the best possible tools every day.
At TORQTEC, we bring professional technical assistance to your manufacturing floor with one intent…”help you make a difference”. With over 100+ Years of combined industry experience, we understand not every manufacturing scenario is standard.
In evaluating power tools, there are five key factors that engineers consider most influencing in their selection process: Ergonomics, Durability, Productivity, Accessibility & Accuracy.
There are many tooling options related to these five key factors. First we should clarify the definition of the key factors, then summarize how each tool option measures up to the key factors.
Ergonomics….measuring the safety and ease of use between the operator and tool during the assembly process.
Durability…measuring the overall performance, uptime and maintenance costs of a tool.
Productivity…measuring the tool’s speed relative to takt time constraints.
Accessibility…measuring the tool’s ability to access the fastener with operator ease and takt time constraints.
Accuracy…measuring the tools capability to meet your defined engineering specifications.
Primarily, there are two tool types for non-critical fastening: Discontinuous Drive Hydraulic Impulse & Continuous Drive Clutch.
Factors of consideration when selecting a torque tool….
Discontinuous Drive Hydraulic Impulse Tools
Features…
Good weight to torque ratio
High rpm
Low vibration
Pneumatic or Cordless
Torque accuracy of +/- 10 to 15%
Torque Range of 5-450 NM
High precision components designed for longevity and durability in industrial environments
Well balanced for low operator fatigue
Ideal applications…Pulse tools are best suited for hard to medium joints. Torque reaction is almost non-existent at torque specifications; thus no investment required for complicated reaction device. It is considered a one-handed tool. Based on the high rpm offering, this tool is ideal for demanding high production environments. Pulse tools require simple fluid changes based the demands of the application.
Continuous Drive Clutch Tools
Features…
Minimal reaction
Pneumatic or Cordless
Good power to weight ratio
Torque accuracy of +/- 10%
Torque Range of 0.3-70 NM
High precision components designed for longevity and durability in industrial environments
Well balanced for low operator fatigue
Ideal applications…Continuous Drive Clutch tools are best suited for softer joints with high prevailing torque. Under load, the continuous drive clutch tool maintains constant speed. It is considered a one-handed tool. However, with the constant speed, the operator is exposed to the process for a longer period. On applications over 50 NM you must evaluate the reaction which the operator may experience. Typically, the torque reaction is minimal.
Selecting the best tool for the application is sometimes not as simple as referencing catalog data and making a purchase. Many times to find the best tool for your application, it involves testing and trials on the production floor with your operators. TorqTec representatives are available to work with manufacturing engineers in your facilities to obtain knowledge of your assembly processes, problems, ergonomic and safety needs. Our Sales, Customer Service Representatives and Repair Technicians are trained and ready to assist you by providing specific solutions and equipment for your needs.
