used a spm with single spindle and 2 vmc.
component output on spm was one component every 45 seconds
component output on vmc would be 10 components every 7.5 minutes apart from manual loading,....
a top the base a two axis slide system is mounted with servo driven axes
on the two axis slide, a fixture is mounted, which can house 4 components at a time.
adjacent to the fixture, a vertical column with vertical servo driven slide is mounted.
on the servo driven slide, a 4 spindle milling head is mounted. Each spindle is mounted with a ø4mm end mill.
all the sliding surfaces made of lm guides and blocks. Drive is through servo motor connected to ballscrew through servo reducer and couplings.
recirculating coolant system is provided for easy chip flushing, improving tool life & for better finish.
hydraulic power packs and cylinders of our make.
complete machine enclosure is provided to contain the coolant and chips.
siemens sinumerik 808d advanced cnc controller is provided for machine controls.
sequence of operation:
load the job onto the fixture and press auto-cycle. The job gets clamped
the milling head moves to mill the profile slot with the help of two axis servo slide system.
after one pass the vertical slide lowers the milling head and another pass is made.
all slides move to home and job gets de-clamped.
final conclusion:
vmc:
component setup time is high.
machining time is high.
due to manual clamping, operation is prone to operator’s fatigue, which may lead to loss in efficiency of production.
an expensive vmc is used for low production output
four spindle cnc profile milling spm:
no need of skilled operator. Cost of skilled operators is reduced.
uses 4 spindles for 4 components at a time.
the total milling time is 35 seconds, for 4 components instead of 7.5 minutes for 10 components on a vmc. Efficiency is more than 3.5 times/ 350%. Increases the productivity, increases profitability, increases the scrap generation rate.
due to cnc controls this has a flexibility of a vmc, but has the production capacity of spm
