Advanced 4C Software
What is 4C Software? Rottler’s newest EM Series equipment offers Computer Numeric Control (CNC), Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) in the industry’s most advanced Computer Measuring Machine (CMM). The 4C technology allows users to digitize, edit designs and begin cutting in less time but also requires less machining/programming expertise compared to many other systems. This brand new, revolutionary CNC machine CAD/CAM software allows 3D CAD Solid Models to be imported or created at the machine – the built-in CAM functions can be used to semi-automatically and interactively create complex 3D tool paths direct from the CAD geometry.

One of the main features is the EM series’ expanded size 32˝ touch screen – by maximizing screen size, Rottler’s CAM software allows unprecedented amounts of information to be displayed for the operator’s use. The user can choose the information to be displayed for incremental and interactive functionality.

Dimensions input through touch screen:

Bore Centers, Exact Depth, Speed, Feed, etc.
Bores complete bank in Automatic Cycle.
Lower Bore Relief, off center boring for Honing Clearance.
Surfacing Multiple Pass programmable for roughing and finishing can remove any amount of material in one automatic cycle. Enter desired deck height of block and themachine will cut to that height. No more guess work!
Lifter Bore Machining - bore housings and bushings to exact final size.
Automatic line bore cycle completes all main bearing housings to within .0002”.
Face main line thrust bearing faces square to crankshaft centerline.
Machine a radius for stroker crank connecting rod and bolt clearance.
Rottler PATH CNC program allows G code programming and file transfer with CAD/CAM programs.

H80 Series The NEW H80X Series Ad
H80 Series H85AX Brochure
H80 Series H85AX Optional Equipment Catalog

Overview
The H85AX hones a complete line of cylinders - automatically! Hone a complete V block unattended with optional auto-rotate V fixture. Automatic lower crash protection safeguards stones and holders from unexpected - and expensive - damage, keeping jobs on time and on budget. The automatic load control gives perfectly round and straight cylinders, and automatic CNC control finishes very cylinder to the same size. Because the H85X accepts both diamond and CBN abrasives, shops get the perfect surface finish no matter the block construction.

Features
Special Version Production Machine that can move automatically in X axis for programmable hole-to-hole block honing - hones a line of cylinders unattended. Automatic Lower Crash Protection System Many Engine Blocks have interference in the lower area of the bores and can damage honing stones and holders. Everytime the H85X starts honing a cylinder, the machine will check bores for interference avoiding potential damage to honing stones and holders. Variances in lower bores are common. Rottler H85X Control senses lower bore interference prior to rotation and stroking stroking motion starting at full power, eliminating any stone or holder damage.

Standard Equipment
Automatic Lower Crash Protection System – every time cycle start is activated, the machine will check that the stones will not interfere with lower bore before starting rotation and stroking preventing stone and stone holder damage.
Spindle Taper with Quick Change System - change hone heads in seconds without any wrenches
Automatic Honing Stone retract at End of Cycle – the machine will automatically retract the stones during last stroke so that the stones do not leave any scratches or marks in the bore.
Automatic Cross Hatch Angle System – the machine will automatically adjust parameters to programmed cross hatch angle and finish the bore to programmed angle.
Automatic Roughing and Finishing Load Sensing System - machine short strokes or dwells anywhere it senses a tight area.
Electronic Hand Wheel for lowering hone head into each bore
Automatic Stone Feed-out System - once hone head is positioned in the bore, the machine automatically expands stones and rotates slowly before starting hone cycle
Automatic Plateau Brush Finish Program - the machine automatically expands plateau brushes to programmed load and counts down number of plateau strokes, then withdraws the brushes and retracts to the clearance position.
Control and programming through 15" (400mm) CNC Touch Screen Control

It's Trivia Tuesday!!🥳Today's trivia... 40% of all "Check Engine" warning lights are caused by....?
a) need to tighten fuel cap
b) faulty oxygen sensors
c) needing new spark plugs
d) replacing your catalytic converter
It's b) faulty oxygen sensors!!
The oxygen sensor measures the amount of unburnt oxygen in a car’s exhaust system. An engine will keep running even if an O2 sensor needs to be replaced, but it will burn more fuel than usual. A bad O2 sensor can damage components like the spark plugs and the catalytic converter. It may also cause a car to fail an emissions test.
Make sure you check your engine when this light is on!!😁

It's Trivia Tuesday! 🥳 Today's trivia.. What's the most stolen car in America??
The Honda Civic is THE most stolen car in America!!
On average, 2052 cars are stolen every day. Considered another way, that’s over 85 car thefts per hour. Professional car thieves generally are uninterested in jacking the latest McLaren or Bentley. They target popular and long-standing model lines like the Toyota Corolla or Honda Civic. The cars are then dismantled and sold for parts on the black market. Parts for popular models are in high demand due to the multitude of owners with the same model, and they generate more money than the value of the car intact. High demand for parts makes these cars lucrative targets for thieves.
Did you think it was going to be a more expensive car?? Comment Below 😁🧐
