The answer is simple, with offline tool presetting you are reducing set up time and eliminating the influence of operator skill level on the accuracy of setting. Does that mean the operator is being replaced by a machine? No, it only means the operator’s time is better utilized and he/she has more free time for performing other value-added activities. For example, an operator currently controlling one CNC machine may be able to handle an additional CNC machine because of the tool setting time saved by the offline tool presetter. Also, because of the user-independent nature of an offline tool presetter, any operator irrespective of the skill level can measure/set tools precisely and avoid inconsistency arising from the skill intensive conventional touch-off method. These aspects help shield the manufacturer from effects of market volatility which may include issues like downtime, high demand, operator unavailability, lack of skilled manpower, etc.
“But aren’t tool presetters expensive and meant only for bigger OEMs?” is a typical question that I encounter when interacting with decision makers from MSMEs. And the simple answer to that is – No. ‘Expensive’ is a relative term and we always need to look at the value a tool presetter brings in by analysing its cost saving potential and by calculating an approximate payback period. For that we have formulated an ROI sheet that helps the manufacturer arrive at a payback period based on the manufacturing setup and the suitable variant of the tool presetter chosen.
The above Excel based table shows a sample calculation that makes use of simple manufacturing data and calculates the tool setup time costs associated with the entire process. This is then compared with the setup time invested after employing an offline tool presetter, and the effective advantage in terms of the setup time cost saving is formulated. The potential cost saved is then compared with the cost of the tool presetter to calculate the payback period. In the example below, I have considered INR 9L as the investment for an entry-level tool presetter from ZOLLER just like the >>smileBasic<< (the value is just a reference figure and not a commercial offer!). In this particular example the payback period turns out to be 15 months, which is quite a reasonable period for any MSME making use of only three VMCs. Also, there are additional benefits in the form of cost saved due to reduced quality rejections by setting the tool ‘right the first time’, and improved tool life as a result of precise setting.
The »smileBasic«
The »smileBasic« is a simple but powerful offering from ZOLLER. In contrast to the term ‘basic’ the »smileBasic« is not really basic! That’s because there is zero compromise in terms of what’s going into building this modern tool presetter. It is built with the same special Aluminium alloy that we use throughout the ZOLLER product range. It makes use of the same branded hardware components that other variants make use of. Then what makes it more affordable than some of the other presetters in the line-up? Simple, the »smileBasic« offers just the right features that a manufacturer needs for starting a journey in the world of professional tool presetting.
In MSMEs, a new piece of equipment such as the tool presetter that supports and enhances the manufacturing process has traditionally been treated as a ‘good to have’ rather than a ‘must have’ product. Times have changed, so has the competition. In order to have a competitive advantage in the manufacturing process in terms of quality, throughput, and process reliability, MSMEs need to explore new products on the shelf and update their existing process. The ROI calculation is easy and so is buying the »smileBasic« tool presetter. You just have to send us an email or pick up the phone and give us a ring. Your competitors have done it, what are you waiting for?
