Red Ring gear grinders

Machine Tool Builders, Inc. in no way represents or sells new Red Ring or Nachi or National Broach Machinery or Products. We do however service, repair, resell, rebuild and re-control used machines or customer owned equipment.

MTB has rebuilt and re-controlled three Red Ring SF-500  and one SF-1000 Gear Grinder, 2 were done for Nachi as broach grinders and two others were for aerospace customers to grind larger OD internal ring gears. The first two were done with a Siemens 840D controls and the last two were done with Fanuc at the request of Nachi.

We would be only to happy to recontrol and rebuild your SF machines or other Red Ring gear manufacturing machines
