Indexing Technologies offers its CTM automatic toolchangers in four standard frame sizes: the CTM 20, CTM 30, CTM 40 and CTM 50 models. Tool capacity ranges from 12 to 30 tools, depending on the model and configuration. Each toolchanger consists of a dual-motion, cam-operated exchanger that grasps, extracts, exchanges and inserts tools simultaneously between the spindle and tool magazine. Exchange time ranges from 0.6 to 5 sec. depending on the frame size of the unit, the tool weights and the length of the arm.
A mechanical exchange arm with dual rapid-release gripper hands features built-in safety interlocks. Toolholder pockets are hinged on the storage magazine to enable a 90-degree tilt during a tool exchange. The magazine is assembled on a mechanical cam-driven indexing table operated by a three-phase, self-braking motor. An optional servomotor drive is available on some models. The toolholder tilt unit is pneumatically operated, and the tool taper cleaning head is actuated as the used tool is inserted back into the magazine. A built-in switch system enables precise toolholder identification and can be used to manage migrating tools. A dedicated toolholder-to-tool-pocket identification management system is available as an option.
The toolchangers are constructed of steels, alloys and plastics for a durable yet lightweight structure. In many cases, the toolchanger assembly can be attached directly to the machine without affecting the machine’s performance, the company says.
