0mm escomatic ConCEpt escomatic.ch Unlike conventional lathes, escomatic lathes are based on a unique concept. The material, which is coil stock or bar, does not rotate. The cutting tools mounted onto the spinning tool head rotate around the material. This concept equally qualified for the manufacturing of small, medium and large lot size parts, contributes to the extremely high performance and cost savings achieved with e s c o m a t i c machines.

1 2 3 e s c o m a t i c EC 12: flexibility and precision without compromise MATERIAL FEED Fax +41 32 858 12 05 info@escomatic.ch www.escomatic.ch The material is supplied into the machine from coil (up to diameter 8mm) or from bar (up to diameter 12mm). If coil is used a standalone straightening unit is required. A coil, depending on the type of material, usually has 30 to 80 kg and is unrolled from a reel independent from the machine. For bar material a commercially available bar feeder can be used. The material is pulled across the machine by the material feed system. (A) MATERIAL FEEDING The material is feed and moved in the machine by the CNC controlled Z1-axis and the attached feed collet. The feed collet (type Schäublin F16) is mounted on a tube-system closest to the material guide bush. (B) TURNING The material is feed through a guide bush to the four turning tools on the tool head, which are controlled by axes X1 and Y1. Two turning tools could be used simultaneously at any time. The turning and chip removal is performed by the unique escomatic principle. This consists of having the four cutting tools rotating around the material with speeds up to 8’000 min-1. For a pickle free cutting off the counter collet spindle C1 holds the machined part and is moving it to the back machining unit (DUA) after the cut off. (A) BACK MACHINING The back machining unit (DUA) has six axial positions for a combination of steady and powered tools as well as insert holders for turning and four positions for a combination of powered lateral and angular tools. The counter spindle C1 with C-axis and counter collet (type Schaublin W20) rotates with speeds up to 9’000 min-1. The unit is based on three axes (X2, Z2 and Y2) and drilling, tapping, threading, milling or threading operations can be performed. (B) FRONT MACHINING The front machining unit (DUF) has six axial positions for a combination of steady and powered tools as well as insert holders for turning and four lateral positions for a combination of powered lateral and angular tools. The counter spindle C2 with C-axis and counter collet (type Schaublin W20) rotates with speeds up to 9’000 min-1. The unit is based on three axes (X3, Z3 and Y3) and drilling, tapping, threading, milling or threading operations can be performed. An integrated handling is taking the finished part out of the machine. 3
