WHAT'S NEW

COMING SOON 3 NEW ROTTLER MACHINES FOR OUR CYLINDER HEAD DEPARTMENT

Posted on July 14, 2020 by promarengine

We are please to announce 3 new machines coming to Promar by Rottler Manufacturing. They are the Rottler SG10XY, Rottler S85A and Rottler VR12. Below are details about each machine.

Rottler SG10XY

ACTIV SPINDLE Programmable Automatic Valve Guide-to-Guide Cylinder Head Machining Center

The Rottler SG10XY ACTIV spindle is mounted on a sphere which allows the UNIPILOT to automatically center with the valve guide centerline while the Workhead is floating on air cushions. Once air floating stops and the Workhead clamps, the UNIPILOT and valve guide centerline are maintained while cutting the valve seat.

  •  ACTIV SPINDLE – Spherical Pneumatic Automatic Alignment System built into the Spindle for fast location of the pilot into the Valve Guide and Accurate Centering (Patent Pending)
  • Air Float Work Head on Intermediate Base Plate
  • Heavy Duty Spindle – Diameter 3.150” (80mm) Hardened and Ground with 8” (200mm) of vertical travel.
  • Rottler Automatic Tightening and Quick Release Spindle Lock Nut System for One Hand Operation for fitting and removing tooling to and from the spindle – never comes loose!

Gives Best Concentricity
Rottler’s Rigid Precision carbide centering UNIPILOTS are manufactured to less than one tenth (.002mm) tolerance. Combined with the light weight air float Workhead the SG10XYgives perfect centering in the valve guide and the best concentricity of any machine on the market, 

Rottler S85A

CNC Automatic Surfacing Machine

The S85A model is designed for surfacing from the smallest to automotive and small diesel heads and blocks. The S85A is ideal for the requirements of the performance racing engine builder and production engine remanufacturer. The programmable downfeed with multiple passes is ideal when large amounts of material need to be removed in one set up. Angle milling and weld removal are also easily done in one cycle. Direct Drive Ball Screws and Linear Roller Bearing Slideways on vertical and horizontal movements combine to give precise motion control resulting in precision surface finish. Full Steel Enclosure surrounds the machine and keeps the work area clean and free of chips and protects operators from moving machine parts. Electrical Enclosure mounted on the side of the machine allows the back of the machine to be installed against a wall reducing floor space requirements.

Rottler VR12

Valve Refacing Machine with Centerless Grinding

Rottler’s Centerless Grinding System is able to grind a set of valves to exact same length without adjusting settings. The Centerless System rotates the valve stem on it’s own centerline. Precision drive rollers rotate the valve stem and a pneumatic low friction steady rest support the valve stem similar to a precision balancing machine, resulting in extremely accurate valve stem to valve seat run out less than .0002″ (.005mm) TIR. The Rottler Centerless System allows a wide range of valve stem diameters to be ground without changing any collets or chucks. Stroking Handwheel – The new design stroking handwheel moves the valve back and forth over the grinding wheel. When operator’s hand is removed from the stroking handwheel, the stroking system remains in position until the operator moves the handwheel again.
