The latest RNA range from Tsudakoma, with major developments over earlier models with major increases in speed and power transmission, with new high power pneumatic clamping system. The Tsudakoma RNA-321 is an ideal device for larger VMC machines with a spindle nose diameter of 180mm with options to accept a 320mm (12. 59”) faceplate or can accept a standard or power chuck. The unit has a 115mm spindle nose location with a generous location depth of 45mm with 85mm directly through the table and a has a centre height of 210mm in the vertical position. This device in the first instance is a vertical and horizontal device with options for a backmount motor, which can be found under product code RNA-321R,B. An excellent carrying capacity of 175kg vertically and 350kg horizontally or between centres and speeds up to 25rpm dependent on motor selection. (example given is with a 3000rpm motor) – High speed versions are available with alternative gear ratio, please ask for further information. Net weight of this device is 150kgThe Tsudakoma RNA-321 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 85mm 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 3 to 4 weeks to configure as required.
