Grinder Retrofits:


Perry Automation also has experience upgrading the amplifiers in the Landis Gardner Viking SuperSeries 200 Centerless Grinder. We can replace the existing Kollmorgan Power Block Amplifiers, which are now discontinued, with Geo Brick Amplifiers supplied by Delta Tau.

The installation is transparent to the operator and can be completed in about two days. If you have a need to upgrade your Viking SS 200 Centerless Grinder contact us today for a quotation.


Delta Tau has recently quit selling its PMAC for the STD bus. The TURBO-PMAC-PCI is a logical replacement, but there are some descrepancies regarding the I/O that must be taken into account. The TURBO-PMAC-PCI offers the advantage of flash RAM as opposed to the battery backed RAM equiped PMAC-STD. We know of many users that have lost their configuration settings during power loss due to problems with the battery backed RAM (weak battery, etc.).

One application we have witnessed the need for this retrofit is on Cincinnati Milacron 230 RK Centerless Grinders. These machines were originally equiped with Ziatech DSP cards and PMAC axis cards. We have installed several retrofit packages on these machines.

The installation is transparent to the operator of the machine because we use the same code that was operating on the STD board with some small modifications for the TURBO-PMAC-PCI board. If you have a need to upgrade your "RK" Centerless Grinder or any other PMAC-STD contact us today for a quotation.

Calibration Equipment:

Perry Automation is an authorized distributor of the OmniGage by Tetra Precision Inc. The OmniGage can evaluate the 3-Dimensional accuracy of machine tools in a matter of minutes.

OmniGage taking 3D measurements on a machining center.

The OmniGage utilizes a fiber-fed laser interferometer to measure machine tool positioning accuracy by trilateration. Trilateration is the same geometric method used by GPS systems to three-dimensionaly locate a GPS receiver via satellites. With this 3D information, the OmniGage software can produce displacement, straightness, squareness, roll, pitch, and yaw measurements for linear axes. For rotary axes, measurements of radial, axial, and angular error can be produced, as well as rotary axis orientation (squareness, parallelism) to linear axes.
