Plano Miller With Ram Type Milling Head

The special purpose plano miller with ram type milling head is yet another work-horse from the SEPL stable, built against an export order. This machine, re-engineered from the carcass of an obsolete planer, has a semi-CNC capability. It is built using a ram type milling head, hydraulically operated fixture, ball lead screw and AC servo drive for axes movement. The unique ram type milling head with 500 mm vertical stroke permits heavy-duty plano milling operation as well as an accurate boring and drilling operations. Unlike the cylindrical quill of a conventional milling head, the ram is a box type construction, rigidly supported by 4 taper jibs to ensure the just minimum required clearance between the sliding surfaces. This unique construction ensures a very level of concentricity even when the ram slides to its maximum stroke end. Combination of case hardened guideway strips and Turcite ensures friction-free, smooth sliding movement, as well as a very high level of wear-resistance. The maximum contact area between the sliding surfaces ensures a very high level of rigidity even at the slide-end position, thus making the heavy material removal effortless. AC servo drive for feed permits rapid and accurate pitches positioning, literally adding jig boring capability to the converted plano miller. It also ensures a rapid reverse movement of the table. Ball lead screws for the axes movement help backlash-free, smooth and rapid axes movement. Hydraulically operated swing clamp cylinders ensure instant and rigid clamping of the job. A PLC interface, in combination with the dog-operated, adjustable feed-end limit switches, instils an auto-cycle capability to the machine, making batch production convenient and fast.
