Take a look at a few of the projects that we were given. These photos are just an example of the wide variety of machine tools that we have retrofitted over the years.

Wit-O-Matic Insert grinder retrofit This machine started as a cam driven insert grinder, which took an experienced operator about four hours to change over to run another part. It evolved into a ball screw driven, two path or one path selectable machine with a custom designed, Visual Basic front end PC-based CNC computer control. Now, it takes less than a minute to change over and cycle time was nearly halved. We have developed three of these machines for this company.

OKK500 retrofit We have retrofitted three of this type of machine for various companies. No drawings were available for the redesign of the electrical harness. As a result, we documented all of our work to produce a complete set of drawings for each. These machines are still in service. We replaced the spindle and servo amps, as well as, the CNC controller. We used Dynapath Delta 20 on two and a Delta 60 on the last one for the retrofit.

Boring mill with inductosyn scales We were awarded the job of retrofitting just the NC control with a CNC. Several years later we were asked to retrofit the servo system. The old servos were SCR drives. We used a popular PWM servo amp for the retrofit and kept the same motors. This machine tool was in service for over ten years until the plant closed. The inductosyn scales were easy to integrate into the new system and proved to be extremely accurate.

Monarch VMC 150 with redesigned Z axis This machine was purchased by our company and fitted with a ballscrew on the Z axis where formerly there was a right angle drive. We purchased it for the company that hired us to buy it and cnc retrofit it for them. We retrofitted 3 machines for this company.

Small 4 axis Cincinnati machining center We retrofitted two of these machine tools for this customer. They have 3 linear axes and one rotary. The tool magazine is located on top of the machine with the changer above the spindle. The electrical cabinet was attached to the machine for the cnc retrofit. It is in the next picture.

Electrical panel for the above machine The panel contains a CNC, a 4 axis servo system and a vector drive spindle system. Solid state relays are used to interface items on the machine tool.
