To meet the demand for 'world-class' HMCs for the Indian and global market, BFW has developed the Orion-series of next-gen HMCs.

To meet the demand for ‘world-class’ HMCs for the Indian and global market, BFW has developed the Orion-series of next-gen HMCs. The project was initiated 5 years back as a platform development by the Indian & German engineering team. Today, Orion platform is a preferred choice over imported machines for many reputed auto-component makers and other HMC users in India. Going ahead, we see Orion as a global brand making its footprint in geographies outside India. The Orion story is a successful case study in structured product development process.

Market Outlook

Indian manufacturing is looking ahead for sustainable enhanced growth. Thanks to long-term policies, decisions like GST by Govt and focus on attracting investments in diverse industry segments. The below mentioned segments are expected to grow at healthy growth rate.

  • Auto sector, a major user of machine tools, will grow by 3.5 to 4 times from the current size of US$ 74 billion to reach about US$ 300 billion by 2026. The Indian auto industry has already become the third largest one since 2016.
  • General engineering and consumer durables are likely to grow at 15% during the next two years.
  • New emerging sectors like defence & aerospace, consumer durables, and green investments in auto sectors are likely to enhance demand for machining centres in the coming years

India is the 13th largest manufacturer of machine tools in the world as per the Gartner’s World Machine Tool Consumption Survey Report 2016. Domestic manufacturers have about 30% share of HMC’s consumption in India. The primary drivers for imported machines are higher productivity, precision and reliability. Japan, Germany, Italy and Korea dominate the import machine segment.

To cater to this demand and to favourably improve Indian built HMCs on an equal footing with imports, BFW has introduced the Orion series of next-gen HMCs for catering to the growing requirements of the user industries.

The ‘Orion’ philosophy

Orion is a prominent constellation of eight bright stars located on the celestial equator and visible throughout the world. Orion series is a constellation of eight next-gen horizontal machining centres setting new benchmarks in specifications and performance for our global clients. It is a result of Indo-German engineering excellence for clients seeking cutting edge performance.

The engineering philosophy behind Orion next-gen HMCs is based on four strong principles of:

  • Precision
  • Productivity
  • Reliability
  • Operator ergonomics

The design philosophy behind Orion is ‘modularity in design’ or a design approach that subdivides a system into smaller parts called modules, which can be independently created and then used in different systems. Orion platform has three series, covering a range of pallet sizes starting from 500 x 500 pallet up to 1250 x 1000 pallet sizes. Orion horizontal machining centres are designed and manufactured to deliver excellent machine precision with the use of high-precision components and of thermo-stable materials, which include:

  • Robust structural parts made of cast iron for high rigidity and damping
  • High precision roller type LM guide-ways and DIN standard high precision ball-screws
  • Spindle cooling, ball-screw core cooling and motor flange cooling with PID control
  • Heidenhain linear scale (optional) for higher precision

Design objectives

The primary design objective of Orion product series was to develop next-gen horizontal machining centers with the following features:

  • Precision & productivity
  • Reliability
  • Aesthetics & ergonomics
  • Compact footprint with space-saving measures
  • Completely modular construction with interchangeable spare parts
