| Summary: | Modular spindle consists of spindle shaft and its case, transmission, and main
drive. Spindle module is main part of machining center. Because of that, principles of
spindle module design need to be developed.
Methodologies used for research are literature study and Modular spindle
design. First step in modular spindle design is to define machining parameter. Second
step is to choose motor, transmission, and cutter-holder clamping unit. Third step is to
define spindle and its housing dimension and also bearing position to obtain static and
dynamic characteristic of spindle module. Last step is choose bearing lubrication and
analyze bearing heat generation and grease lubrication interval.
Design of drilling spindle module has been made, by specification power 5,5
kW and maximum rotation 8500 rpm. Maximum spindle static-deflection is 2,4 J.m and
spindle resonant frequency about 700-5000 Hz. Motor chosen for the modular spindle
is Siemens 1PM6-101 and holder nose designed based on DIN 228 Morsekegel.
