VMC / CNC / HMC Spindle Manufacturing at
HP Spindle Technology

Welcome to HP Spindle Technology, your trusted partner for spindle manufacturing, repairing, and retrofitting. With years of hands-on experience in the field of precision spindle engineering, we proudly serve industries across India. Whether it's Vertical Machining Centers (VMC), Computer Numerical Control (CNC) machines, or Horizontal Machining Centers (HMC) – we specialize in manufacturing high-performance spindles to meet all your industrial needs.

What is a Spindle?​

  1. A spindle is the heart of a CNC, VMC, or HMC machine. It is the rotating component responsible for cutting, drilling, milling, or grinding the material. Spindles need to be precise, fast, and vibration-free for the best performance.

  2. At HP Spindle Technology, we manufacture spindles that deliver accuracy, high speed, stability, and durability.

Types of Spindles We Manufacture

  1. CNC Spindles

    Designed for CNC turning and milling machines. High torque and precision.

  2. VMC Spindles

    Used in Vertical Machining Centers. Perfect for vertical drilling, tapping, and milling.

  3. HMC Spindles

    Built for Horizontal Machining Centers. These spindles are ideal for large, heavy-duty jobs.

  4. Grinding Spindles

    For precision surface, cylindrical, and tool grinding applications.

  5. Belt Driven Spindles

    Low maintenance, suitable for high-torque applications.

  6. Built-in Motor Spindles

    Compact and high-speed. Motor integrated within the spindle.

  7. Direct Drive Spindles

    Zero backlash, high response. Suitable for high-precision machining.
