Station Rotary Table Based Drilling and Chamfering SPM

Features & Specs:

• Rigid, heavily ribbed, fabricated and stress relieved structural.
• Atop the base, a servo driven rotary table is mounted which is dived into 8 stations.
• The fixture, will be designed to rest, locate on the ID. The clamping will be through pneumatic swing clamp cylinders.
• Station 1 will be loading station. This station will have a pneumatic pick and place arm in combination with pneumatic cylinders to load the component.
• Station 2 will be clamping station, where the component is clamped.
• Station 3 will be top chamfering station. This station will have a chamfering head with a counter sink drill mounted on it. The drilling head will have a vertical servo stroke for drilling feed.
• Station 4 will be drilling station. This station will have a unit head with Ø1.8mm drill mounted on it. The unit head will have a vertical pneumatic stroke for feed.
• Station 5 will be back counter sink station. This station will have a unit head with counter sink drill mounted on it. The unit head will have a vertical servo stroke for feed.
• All unit heads of Suhner make.
• Station 6 will be inspection station. This station will have a pneumatic cylinder which will plunge into the drilled hole to check for hole.
• Station 7 will be job declamp station, where the job is declamped.
• Station 8 will be job unloading station. This station will be similar to loading station, but will unload the component into a bin.
• The Servo, drive, HMI, PLC will be of Siemens make.
• Each unit head will have a tool sensor to sense the breakage of the tool.
• Centralized lubrication system will be provided.
• The machine will have a recirculating coolant system to flush out the chips.
• The machine will be provided with splash guard.

Sequence of Operation:

• Load the components into the job feeding bin and press auto-cycle.
• The pneumatic cylinder moves the arm over the job, picks the job and places it over the fixture.
• Rotary table indexed, job gets clamped.
• The job gets indexed to station 3 and top chamfering takes place,
• The job gets indexed to station 4 and the Ø1.8mm drill, drills the component.
• The job gets indexed to station 5 and the bottom chamfering takes place.
• The job gets indexed to station 6, where the inspection will happen.
• The job gets indexed to station 7, where the job gets declamped.
• The job gets indexed to station 8, where the job is picked from the fixture and dropped into the chute leading to the bin.
• This process is continuous and when machining operation is going on at other stations, the job loading and unloading will be going on at other stations.
