Data name

Cost reduction by vacuum chuck

Overview

こBecause this work was complicated in shape and was done with clamp metal fittings, it had many steps and was unstable in terms of accuracy. Production number 350〜800/1〜２months

Point

The material which was improved by vacuum chuck in the area of cost reduction, improvement of machine operating ratio, Clamp strain is.A5052S

Result

The time of installation and removal has been shortened by 9/10, so skills are no longer required for installation and removal. So, night operations can be performed,and the operating ratio and processing accuracy of the machining center have been improved.

Commentary

Although this work was initially machined using clamp metal fittings, it took a lot of steps and a long time to remove the work, and only the MC operator could handle the work. 　こThis work had 350 to 800 lots in short delivery time, and could not be processed unless operating time was increased by night operation. Now, it uses a vacuum chuck for reduction of man-hours / of processes and operation at night, shortening installation and removal time, and for cost reduction by improving the operation rate. 　By changing to the vacuum chuck type, it was possible to shorten the conventional work process from 5 steps to 3 steps. 　Screw tightening also disappeared during installation and removal, even workers other than operators could now install and remove in 1/10 of the conventional time. 　Because it does not use clamp metal fillings, it became possible to acquire a wide working space, and it became possible to do a large number of units (5 units in the past). 　Improvements to the vacuum chuck have simplified many pieces and work, so anyone can work and the availabitity of machines improved (including 6H / day night operation).

Comment

In most cases when using a vacuum chuck with a milling / machining center, the mounting base is dedicated to the workpiece. 　Since the clamping force of the vacuum chuck, when applied to horizontal direction, is about 35% compared to vertical direction, this work uses a round pin stopper. 　The base is processed with O-ring groove for preventing leakage and lea groove for improving exhaust performance. 　Neoprene sponge round cord was used for leak prevention O-ring. Toyoron hose was used for the line between the vacuum unit and the base. 　This time, the base was made of aluminum to improve the heat dissipation of the workpiece, and processed with a machine that processes the workpiece. 　Works of the same shape have many achievements.
