Second new product RK200 rotary table launched
At just 99mm deep, the body of the new Kitagawa CK160 rotary table has a smaller footprint than any other model on the market, according to Kitagawa.
The ultra-compact fourth axis is suited to mounting on the table of a BT30 taper machining centre and provides manufacturers with a larger machining envelope on any size of machine.
The thin profile also makes the NC table ideal for use with an opposing trunnion for securing and rotating a workpiece between centres in limited working areas. It may be orientated in the horizontal or vertical plane.
The CK160 is offered with a built-in rotary joint, in which case it is designated CKR160, both versions being 99mm deep. A conventional table would typically measure half as much again from the faceplate to the back. The rotary joint, which has seven ports for pneumatic and hydraulic supplies (but not coolant), allows the unit to operate on the C-axis of a 4-axis machining centre.
Specifications of the product include a 114mm diameter table, 65mm through hole (on the CK160), 140mm centre height, 340Nm pneumatic clamping and 41.6rpm maximum rotational speed. Indexing accuracy is 20 arc seconds with four arc seconds repeatability. Workpieces up to 160kg may be supported with the table mounted horizontally, or 80kg if it is vertical.
RK200 rotary table
‘Unbelievably quick’ is how Kitagawa describes the RK200 rotary table – the second new product. The NC unit indexes through 90° in 0.31 seconds and achieves a maximum speed of 100rpm.
A maintenance free roller gear cam reducer, rather than traditional gear sets, decreases the motor rpm to the table’s rotational speed. This improves positioning accuracy, load capacity and efficiency while reducing heat generation, even under continuous operation.
RK200 has a 114mm diameter table with a centre height of 150mm, 70mm diameter through hole, 240 and 108Nm instantaneous and continuous holding torques respectively, and a maximum table load of 60kg.
