EPOC-VISION™ (Worldwide Patented • A NEWEN® Exclusive!)
EPOC-VISION™ The Most Universal Machine Ever Built Machine seats ranging in diameter from 13.5mm (.52’’) to over 240mm (9.45’’), from the smallest multi-valve motorcyle cylinder heads to the largest cylinder heads weighing up to 3 tons or more.
• machine stellite valve seats at high speeds with CBN inserts for unparalleled geometry
- not permited by any other system.
• adjust actual valve seat angles at will, every one hundredth of degree.
• incomparable precision, flexibility and u
ser friendliness.
• attain PERFECT SEAL between the valve seat and its valve, the first time, WITHOUT LAPPING.
• guaranteed concentricity owing to NEWEN’s Patented centering system.
• guaranteed circularity, within 3 microns per 100mm increment, even on valve seats as large as 200mm in diameter.
• unparalleled speed of execution : 1 to 3 minutes to machine a 170mm valve seat.
• constant speed guarantees perfection each and every time, particularly critical on large diameter valve seats - not permited by any other system.



FIXED-TURNING® for the highest quality
  • numerically controlled axes driven by satellite roller screwsand servo-motors of the latest generation. A precision of the tool travelling by interpolation is measured in thousandths of mm.

  • Z-axis ( 327 mm / 12.87’’) Pantograph™ system (Patented) allows to raise or lower the machine head and spindle at the level of the valve seat to machine. The Pantograph™ is balanced and its movements are pneumatically assisted in order to conserve maximum feel
    while introducing the centering pilot within the valve guide. The Pantograph™ gives added rigidity to the whole machining head and provides a lot of flexibility. Increased machining precision. A NEWEN® exclusive.

  • NEWEN FIXED-TURNING® machining head featuring patented friction-free, pinion-free and maintenance-free kinematics, capable of machining with the highest degree of precision, year after year. Pilot centered and held by an original and particularly efficient crush sleeve system.

Precision in every component and detail 
  • The spindle glides through a spherical housing supported by a double air cushion, spherical and plane. The combination between the rotation of the sphere and its movement on the x and y axes allows the sphere to take any position inspace, without any constraint, and to align itself perfectly with respect to the valve guide. Automatic centering with programmable temporization. Automatic re-centering of the spindle with pneumatic jacks.

  • Machine head, pressurized by constant air fl ow for protection of all the precision mechanical components against metallic operating dusts.

  • Electronic and electric components interconnected with quick plugs. Electronics entirely protected with stand alone suspended shock-proof cabinet. Electronics conceived and produced by NEWEN ®.

  • Solid honeycomb-design machine upper ways confers stability, longevity and precision to the machine.

Improved ergonomics :
  • Modular upper bench to accommodate smaller size cylinder heads, Featured with SGC200M , palletizable™, 360° double-angle manual rollover clamping fixture. Allows quick positioning of most cylinder heads regardless of the valve guide angles. Also allows to simply raise cylinder heads to any desired level and to roll them over for various jobs. This patented system is quick, universal, very rigid, user friendly and does not put any stress on cylinder heads owing to its independant jaws and spherical collet system.

  • Heavy duty table to accomodate cylinder heads weighing up to 2 tons and more. Simple, fast and efficient pneumatic lock to ensure effortless positioning of any cylinder head.

  • Built-in low-voltage multipoint lightning (LEDs) - cold light. The work area is paricularly well lit, the control of the finished work is improved and, consequently, the operator’s fatigue is reduced.

  • 15’’ Fanless Industrial PC of the latest generation, IP65, with built-in flat touch-screen. A user-friendly and intuitive dialogue between the machine and the operator. Unlimited memory capacity.

  • Control panel fitted with push-buttons, protected by an interchangeable lexan, and a multifunctional electronic wheel. Precision. Reliability

  • Stress relieved welded frame coated with industrial resin, resistant to any chemical agent (High frequency stabilization during welding).
