Manufacturer Receives Recognition in Fastener Technology International 25th Annual Top Products of 2021
Kinefac® Corporation, Worcester, MA, USA, oﬀers the 50 ton CNC servo-electric three-die thread rolling machine with synchronous three-die actuation in a compact vertical or horizontal rolling axis. The MC-9 HD CNC KineRoller™ was developed speciﬁcally with high-end aerospace and similar precision fasteners in mind. It can accommodate both warm and cold rolling applications. All three-die spindles actuate toward a common centerline in synchronized motion. Each spindle unit is guided on a heavy-duty precision bearing slideway and has independent taper adjustment. A single point size adjustment ensures all three spindles reach their commanded position simultaneously. Maintaining a common part centerline reduces the risk of rolling drunk threads and makes for easier manual or automatic part handling. The vertical rolling axis oﬀers a compact footprint while further simplifying part handling and the risk of drunk threads. The dies lubrication sump is integral to the machine base and the electric die actuation eliminates the need for space-taking hydraulic power units. Optional chilling of the lubrication is available Various spindle cap attachments allow large or oﬀ set part head geometries to swing between the bearing blocks. With standard die spindles, the machine is capable of rolling threads from 7/8″ up to 4″ diameter and thread lengths up to 5″ in various high strength alloys such as Inconel, Monel, Waspaloy, and A286. Standard die spindle conﬁgurations include 2-1/2″ diameter x 6-spline drive or single key drive to accommodate your existing dies. Optional 1-9/16″ and 1-7/8″ x 6 spline spindles are available as quick-change units with reduced load capacity to extend the minimum thread size range down to ¾” with thread lengths up to 4″. The KineTrol™ CNC system guides the operator through an interactive experience to make setups fast, eﬀective and safe.
