A rotary milling SPM used to mill ingates was developed for a foundry based company as a solution for the following problem:

• Inagates of castings had to be removed before machining on VTLs.
• They were previously being removed by hand grinding.
• This was a laborious process requiring a lot of man power.
• There was a lot of dust, which was hazardous and of no use.

Key points of the solution offered:

• The ingates are milling within minutes compared to the previous numerous man hours spent to hand grinding.
• Better tool life of the final machining as ingates are removed uniformly.
• Milling chips are generated which can be used again in castings. Earlier these becoming powdered chips which could not be collected or used.

Features and Specs:

• Rigid, heavily ribbed, stress relieved, cast iron structure for slides. Fabricated structure for base.
• Atop the base, a vertical column is mounted with vertical slide.
• Both the slides are made of LM guides and blocks.
• Atop the slide, a 5 HP all geared milling head is mounted.
• The cross slide is driven by ballscrewscrew, coupled to inline servo reducer and servo motor.
• The machine also has a rotary table mounted in front. The drive is motorized and routed through servo motor with variation between 0-15 RPM
