The Tsudakoma RNA-251 CNC rotary table without motor, can be prepared to suit any interface at additional cost (see our interface listings for details and costs for “external interface” (motor, switch, cable and connector requirements if you already have a “4th axis interface” in the machine) and machine interface costs (if you do not have the additional axis fitted).
Motor is mounted to the right hand side on this device and may restrict the Y axis capability in certain circumstances, the centre hole of 50mm is available should you want to machine long bar components that need to be mounted through the centre.
This range of Tsudakoma devices now come with dual lead full depth worm and wheel, which means that there is less load on individual teeth improving wear and torque performance over and above the conventional standard gear.
Tsudakoma is one of the oldest and original manufacturers from Japan and in our experience build a very fine device with a very long service life, probably greater than those we have experienced from other Japanese makers.
Tsudakoma products carry a standard one year parts and labour warranty and have a full working partnership with CNCROTARY.COM.
This device may take from 2 to 3 weeks to configure as required.
