Customer’s Initial Machining Process:

• Used a VMC.
• Clamping sing a C washer and bolt mechanism.
• True the job which would take around 5 minutes.
• Machining cycle time for drilling of Ø31.75 mm for a depth of 56.3 mm using a U drill would take around 35 minutes.
• A Total of 40 minutes used to be taken up for one job to be completed.

• 2 servo controlled axes for (a) rotational movement of the rotary table, (b) cross axis movement of 10 HP drilling head, which can do drilling upto Ø36 mm drilling.
• Servo controlled linear axes movements & rotary movement are for accurate pitch selection & accurate indexing respectively.
• Drilling head with special angular contact bearings arrangement for high level of accuracy & rigidity. Head driven by a 10HP motor with a combination of gears and timer belt and timer pulley arrangement for obtaining required speeds without torque drop.
• Ball screw, box nut mechanism in combination with gear box for cross axis movements of the milling head.
• Hydraulically operated vertical movements of the drilling head.
• Swing clamp cylinder can be provided for automatic clamping.
• Touch Screen enabled HMI (Human Machine Interface) for quick “on machine” program selection, program editing by the operator & quick troubleshooting.
• Male sliding surfaces are with case hardened guideway strips and female sliding surfaces are with turcite lining for smooth axes movement & best wear resistance.
• Centralized automatic lubrication to lubricate all rotating & sliding parts at pre-set regular intervals.
• Machine enclosure & guideway protection
• Machine to have PLC program.
• High pressure coolant thru with rotary joint for quick chip evacuation
• Total machine enclosure, required for high pressure coolant dispensation.
• Chip conveyor for easy chip disposal.

• Load the job onto fixture manually
• Close the door and press auto cycle.
• Job Clamps.
• The servo driven horizontal slide moves from home to required distance to obtain the pre-fed PCD.
• Spindle ON, coolant ON, Vertical hydraulic slide having head mounted moves in rapid to the cutting zone and slows down to the required feed rate while cutting.
• Vertical slide retracts out of the hole and table indexes to the next pre-fed angle for drilling next hole.
• Same indexing & drilling is followed upto 360°.
• The slide and table moves back to home.
• Job unclamps, unload job.

• One of the setbacks in owning a VMC is requirement of CNC programming knowledge to alter or change the program.
• In our machine with a HMI, programming knowledge is not at all required. Simple instructions can be followed on screen to modify or change the program.
• Working as shown in the upcoming slide.
