Special Purpose Machines
Multi-operation Rotary
Indexing Machines
WIDMA’s rotary machines are designed for simultaneous execution of multiple operations like drilling, tapping, rough boring, fine boring, spot facing, and reaming. These machines are usually handled by a single operator. This offers the benefit of the best possible productivity and cycle time.

Typical Components

  • Cylinder head
  • Crank shaft
  • Rocker arm
  • Connecting rod
  • Cylinder Block
  • Compressor Crankcase

Valve Seat Machining and
Valve Guide Reaming

Built for accurate machining of valve seat profiles and valve guides for engine cylinder heads, these machines span a range of diameters for generation and plunging. WIDMA is the first to develop these machines indigenously in India.

Typical Components

Cylinder head for four-wheelers and heavy vehicles
Fine Boring Machines
WIDMA offers fine boring machines of vertical and horizontal configurations with single or multiple spindles. The tool correction feature of these machines works up to an accuracy of 1 micron diameter. Besides, the tool retract mark can be eliminated during tool return. Bore tolerances from IT6 to IT8 and surface finish of 0.8 to 1.6μ Ra. can be achieved, depending on the material of the component.

Typical Components

  • Cylinder head
  • Cylinder block
  • Crank shaft
  • Crank case
  • Connecting rod
Multi-spindle Machines

WIDMA’s multi-spindle machines are built to perform multiple operations simultaneously and offer the best-in-class cycle time. Available in horizontal and vertical configurations, they can be provided with rotary or linear indexing.These machines can be used for operations such as drilling, tapping, rough boring, fine boring, reaming, and spot facing.

Typical Components

  • Crankcase and crankcase cover
  • Cylinder head
  • Cylinder block
Facing and Centering Machines

WIDMA facing and centering machines are available in both vertical and horizontal configurations with slides for plunge or traverse milling. They provide accurate center and face reference for further operations like turning and grinding.
• Two spindle machine for smaller shafts
• Four spindle machine for shafts of larger diameter

Typical Components

  • Cam shaft
  • Crank shaft
  • Input shafts
  • Output shafts
  • Turbine shafts
  • Transmission shafts
  • Stub axles
Special Milling Machines

For special milling applications, WIDMA offers machines with multi-axis movement and interpolation. By performing the primary material removal task, they save time needed for subsequent operations. WIDMA’s special milling machines can be offered for operations such as cam lobe milling, profile milling, keyway milling, groove milling, slot milling, and pad milling.

Typical Components

  • Cam shaft
  • Gear shift drum
  • Crank shaft
  • CRI nozzle body
  • Transmission shaft
Heavy Milling/Roughing Machines

Heavy milling and roughing operations require high material removal rate with high depth of cut. These applications also require spindle with gear box to achieve the required cutting torque and power. WIDMA machines are designed to meet the said parameters in demanding applications, and can be customized for a variety of tractor, car, and truck components.

Typical Components

  • Cylinder block
  • Crank case
  • Transmission case
  • Cylinder head
Finish Milling Machines

WIDMA’s finish milling machines are designed for achieving critical accuracies like flatness, surface finish, and milling depth. They are provided with rigid spindle bearings and sufficient power for stability and near zero vibration. These machines can be configured in horizontal or vertical configurations depending on components and machining complexity.

Typical Components

  • Cylinder head
  • Cylinder block
  • Crank case
  • Transmission case
