B.R.PRECISION HEAVY DUTY ROTARY TABLE
B R Precisions Rotary Table
These tables are very useful for every work shop where accurate rotary movement is called for. They are principally used for milling sectors of circles, drilling, slotting and shaping as well as circular dividing operations. The equipment is made of high grade heavy duty cast iron with Brinell hardness of 200 and precisely machined, hand scrapped to close to tolerances. On the rotary tables, the work piece must be aligned with respect to center bore clamped in 'T' slots. Dividing is done by means of hand wheel or knurled knob which operates the worm and worm wheel. The table is graduated from0 to 360 for direct setting and with the graduated collar on the worm, The Transmission Ratio is ( 1:120 ) the dividing can be done up to 2 minutes of an arc. The parallelism of the table is 0.02 Microns
