4. CNC ROTARY TABLE LURICATION: The main bearing, worm gears and other bearing are immersed in an oil bath . Oil is to be maintain approximately midway of oil level indicator. OIL FILLING AND DRAINING For filling of oil, remove the plug from oil filling port. . Fill the oil to the level marked in oil sight glass now, fit the plug back. Oil is drained through, drain plug provided at the bottom. OIL CHANGE Change the oil of rotary table within 1 month from the date ofInstallation. Change the oil with fresh oil after intervals as per the guidelinesbelow: o If usage is 8 hours per day (1 shift), replace oil within every 6months o If usage is between 8 hours to 16 hours per day (2 shifts), replace oilwithin every 4 months. o If usage is more than 16 hours per day (3 shifts), replace oil withinevery 2 months. The quantity of oil required for replacement is 1 litre for 215mmmodel. Recommended lubricants: o ISO VG 460 o ISO VG 220 • • • • LUBRRICATION OIL: Servo way 220 or its equivalent .i.e., Lub. Oil with viscosity grade 220 @ 40º C (cst) and Flash Point 230º C CLAMP CONFIRMATION ADJUSTMENT: The Position of the reed switches on the cylinder can be adjust for proper sensing. The reed switch can be moved in the slot on the cylinder . To adjust the reed switch, loosen its lock screw and move it to or fro, after locating it in the right sensing position, lock it with its screw. The actuation of the reed switch is indicated by the glow of the LED provided for each switch. BACKLASH ADJUSTMENT: It is required to adjust backlash after prolonged use. The procedure to adjust backlash is given below. The allowable backlash of the table is 0.02mm on the peripheryoftherotary table. 2800+ Product Installations 25 States 29.5 Cr Prevented Revenue Loss 850+ Clients 170+ Cities www.kuvamtechnologies.com www.kuvamtechnologies.com marketing@kuvamtechnologies.com 9560500384

5. Installation Steps 1. 2. 3. 4. 5. 6. 7. Installation Method Erase rust-preventing grease, then put rotary table on the machinetable. Connect power, motor encoder signal lines, and airpipe. Adjust vertical and parallel accuracy by X, Y, and Z axes of themachine. Fasten rotary table on the machine table by pressureblocks Set parameters on thecontroller. Do Runningtest. Zero Return Adjustment and grid shift amount setting (1).When the machine receives Zero Reset Command from NC controller, the Rotary Table willstart to rotate in the specifiedforwarddirectiontozeroposition. (2).When the Zero Dog touches the Proximity Switch, Rotary Table starts to decelerate foran accurate andpromptstop.(see Fig 1.1) (3).When the Rotary Table reduces its rotation speed, it will stop at Zero when a referencesignalfromthe motor is received. (4).Perform turntable operation several times; measure errors between the actual stopping point and nominal stopping point of the Rotary Table. Enter the measurements into ZeroOffsetoftheNC System forcorrection.

6. BACKLASH ADJUSTMENT Turn offpowerandcutof pneumaticsupply. The backlash can be measured with a deflection dial gauge by inserting a flat steel plate into a T-slot of the rotary table and shaking the periphery there of left and right through the plate with hand. Measure the backlash again and make sure that it is between 0.01mm~0.02mm, the adjustmentis requiredwhena backlash of above 0.05mmisobserved.

Please take percussion for following possible reasons to protect your machine and table. Wrong Method Rotary no firm fixed Cutting method Precaution Please, refer to installation chapter for fixing table on machine Check and sharp cutting tools before use. Avoid interference of tools and work piece. Firm fix the work piece on table. The tolerance between table and tailstock is less than 0.01 mm Avoid cutting force greater than suggested value. Return zero point before working. Backlash parameter should be set at proper value. Crashed machine may cause parts damage, inaccurate index or noise curing index.
