CNC Machining Cells

200+ CNC Turning Lathes and 20+ VMC machines with 4th-axis tables executing multi-tasking functions.

Multi-tasking CNC Machining

Srimukha’s machining shop specializes in roughing and finish turning of complex automotive parts. With a fleet of modern Indian, Japanese and Chinese CNC machines, we hold tight tolerances on diameters, concentricity, and roundness across millions of parts annually.

High-Precision Machine Fleet

Our precision machining facility is equipped with automated CNC lathe and milling centers:

  1. 150+ CNC Turning Lathes: Heavy-duty turning centers (Tsugami, Lokesh, Mazak, ACE, LMW) featuring programmable tailstocks and rigid turrets.
  2. Twin-Spindle Muratec Lathes: Turning cells with integrated automated gantry loaders for high-volume automotive shafts.
  3. 30+ Sliding Head CNC Lathes: Heavy-Duty Sliding Head Lathes with bar feeding for high volume motor shafts.
  4. 20+ Vertical Machining Centers (VMC): High Torque spindle Brother machines with 4th axis capabilities and rotary index tables and coolant-through-spindle (CTS) systems.
  5. 10+ CFM Machines: Centering & Facing Machines for Cold Forged/Hot Forged EV Motor shafts.

CNC Process Workflow

Forged blanks or bar stocks are loaded onto the CNC turning lathes. The first setup performs rough turning, facing, and center drilling. The second setup executes finish turning of bearing diameters and seal grooves. In VMC cells, axial holes, keyways, and radial cross-holes are drilled and milled under high pressure coolant.

“Using gantry loaders and twin-spindle machines, we eliminate manual load errors, maintaining process capability index (Cpk) values above 1.67.”

Tolerances & Dimensional Quality

Parts are checked at the machine using digital air rings and snap gauges. Bearing journals are held to dimensional tolerances under 20 microns, roundness under 5 microns, and surface roughness under 1.2 Ra. Calibration is verified using master setting gauges. Feedback systems are provided to monitor critical dimensions and sustained production levels.
