CH-CM0406 Cut-Prepoint-Chamfer Machine

Rush Machinery Cut-Prepoint-Chamfer Machine
Machine Description
  • The CH-CM0406 CNC Cut-Prepoint-Chamfer Machine is designed for converting full length, blank carbide rods into tool blanks for fluting and finish grinding. Cuts to length, prepoints, and chamfers. Also does cuts only, chamfer only, or cuts and chamfers.
  • The machine makes carbide blanks that are ready for finish tool grinding. It is ideal for cutting tool manufacturers that want to make tools from a blank that is already pre-pointed and chamfered. The machine is easy to setup and runs unattended.
  • Prepoint and chamfer angles can be generated through interpolation. The parts are held in place by two collets and the part is
    transferred from the cut and prepoint collet to the chamfer collet by a separate transfer device. A gripper deposits the completed piece into the collection basket.
  • Six easy steps to setup:
  • 1.  Adjust the loader fingers
  • 2.  Install the correct collet and rod guides
  • 3.  The feeder V tray height is automatically adjusted
  • 4.  Install proper wheels for prepointing, cut-off, and chamfering
  • 5.  Setup pick-and-place unloader
  • 6.  Setup or recall from memory the runtime program in the controller


  • –  Round cutting blanks ready for finish grinding
  • –  Reduce time in finish tool grinder
  • –  CNC automated controls:
    •     –  Combines 3 processes into a single machine
          –  Saves process cycle time
    •     –  Saves labor
  • –  Inventory reduction:  Raw rod of diameters needed, but not
  •     specific lengths
  • –  Greater flexibility:  Form tool blanks to match orders from
  •     blank rod
  • –  Reduced material cost:  Use blank rod to make order-specific
  •     blanks
  • –  CNC controller
        –  User-friendly touch screen for programming and
            parameter setting
        –  Pause program for parts inspection

–  Servo motor with four axis Servo control

  • –  Parts basket drawer can be opened without stopping
        machine to access finished parts for inspection and/or
  •     removal
    • –  Raw rod end locator stop to minimize end waste
  • –  CBN plated wheels (wheel position can be varied)
        –  Prepoint/Chamfering angles: 60º–135º included angle
        –  Use the 30º wheel for 60º–90º included angle
        –  Use the 45º wheel for 90º–135º included angle 
  • –  Automatic loader
        –  Part presence sensor
        –  Adjust fingers
        –  Ball bearings to prevent more than one rod loading
        –  Diameter range:  3/64″–1″ (3mm–25mm)
        –  Length range:  3″–23.5″ (80mm–600mm)
  • –  Automatic unloader
        –  Diameter range:  3/64″–1″ (3mm–25mm)
        –  Length range:  3″–23.5″ (80mm–600mm)
  • –  Finished parts
  •     –  Diameter range: 3/64″–1″ (3mm–25mm)
