Top Pick for: Job shops that do a wide variety of engines, including diesel

The S85A is ideal for a job shop that does a wide variety of engines including diesel. Built for surfacing a wide range of blocks, from the smallest block to automotive and small diesel heads and blocks. The S85A is an ideal machine for the performance racing engine builder as well as the 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 deliver precise motion control resulting in a precision surface finish.

Full steel enclosure surrounds the machine and keeps the work area clean, free of chips, and protects operators from moving parts.

Side-mounted electrical enclosure lets you place the back of the machine against a wall reducing floor space requirements.

S85A Features

ClearPath Integrated Servo Control Technology

State of the art electronic controls make the S80 machines the most advanced dry cutting surfacing machines available today.

Increased Vertical Travel

Workhead is mounted on linear roller bearing slideways and has extended travel 19″ (483mm) eliminating the need for parallels while being able to surface a wide variety of jobs from small single cylinder heads to tall diesel blocks.

Linear Roller Bearing Slideways

Vertical and horizontal movements are by precision ball screens and on linear roller bearing slideways.

Super Fine Surface Finish

Direct Drive precision ball screws and linear slideways combined with infinitely variable speeds and feeds allows surface finish as low as 2Ra to 6Ra. Today’s MLS (Multi Layer Steel) head gaskets require super fine finish to seal combustion pressure and oil and water.

Dry Cutting

Spindle and cutterhead system is specially designed and developed for dry cutting with CBN and PCD cutting tools eliminating the need for coolant.

Chip Collection System

Base casting and machine enclosure is designed to catch chips and direct them down into a roll out chip bin making clean up fast and easy.

Reduced Floor Space

Traveling Column Design and compact, one piece base castings give the most compact surfacing machines available today reducing floor space requirements.

Folding Doors

Stainless steel doors fold down for access to the work area and fold up to protect the operator and keep the work area clean of any chips.

Universal T Slot Base

Large One Piece Mehanite Cast Iron Base with T-Slots allows mounting of any fixture and any job -jacks and clamps can be placed anywhere!

Program Length of Part

Input length of surface to be machined and the machine travels the exact distance then returns to home – not necessary for time consuming setting of end stops.

Fast Floor to Floor Time

Heads can be surfaced in a few minutes and a pair of angled V8 heads in less than eight minutes.
