Pulling Force Measuring Tool Even the use with 5m cable, it can be measured both manual tool change and ATC. P.303 Unique Construction ： Considering of a slotted taper cone which is pre-loaded by a disc spring to increase its vibrational dampening effect whilst adjusting minute gauge-line errors, completely.
E.H.Merritt’s Theory Chattering Stability ＝
Static Stiffness × Damping Ratio Thus, the advantage of NC5 TOOLING SYSTEM is clearly demonstrated.
★ A bove Code No. includes Ring GAUGE （ SG-R ） and Plug Gauge （ SGT-P ） . ★ Dial Gauge is not included with the Ring Gauge.
NC5 TOOLING SYSTEM is basically developed for the Machine with Centre Through Coolant capability, however, of course, the system is also suitable for the Machine without Centre Through Coolant capability. NC5 TOOLING SYSTEM takes advantage of the powerful pulling force to improve its static stiffness. Therefore, please ensure that at least the following pulling force figures in the table are required for each size of NC5 TOOLING . The Pulling Force Measuring Tool with special Pull Stud is available for the pulling force measurement. For manufacturing of NC5 Machine Spindle, we could supply the Gauge for Machine Spindle as well as any other know-how about Spindle Flange Cleaning, Drive Key Mechanism and so on. Please contact with us for any technical correspondences if required.
