Bangalore, India – May 11, 2025. A leading enterprise in India’s auto parts industry officially announced that it has signed a procurement agreement with Shandong Dezhou Guanghe Machine Tool Co., Ltd. of China to introduce the ZK2102*600 CNC deep hole gun drilling machine. The equipment is used for small-diameter deep hole machining of core precision auto parts such as gearbox shafts, fuel injection system components and engine connecting rods. Scheduled for delivery and commissioning in July 2025, it will comprehensively improve the enterprise’s deep hole machining accuracy and production capacity after operation, and boost the high-end transformation of India’s local automotive supply chain.

I. Procurement Background: Automotive Industry Expansion Drives Precision Machining Upgrade

As one of the world’s fastest-growing automotive markets, India’s auto sales exceeded 4 million units in 2024, a year-on-year increase of 18%, with the market share of new energy vehicles and high-end fuel vehicles rising steadily. Established for over 30 years, local top-tier parts supplier ACI covers engine systems, transmission systems, chassis components and other products, serving mainstream automakers including Tata Motors, Maruti Suzuki and Hyundai Motor India, and acts as a core supplier in India’s automotive supply chain.

With global automakers raising higher standards for parts in precision, reliability and service life, traditional processing equipment is plagued by unstable accuracy, difficult chip removal and low efficiency in machining small-diameter holes (φ3–20mm) with large depth-diameter ratio (100:1), failing to meet the demands of high-end orders. To break production capacity bottlenecks and conform to international standards, ACI launched the bidding for high-end deep hole processing equipment. After multiple rounds of technical comparison, sample trial cutting and on-site inspections, the enterprise finally selected ZK2102 CNC deep hole gun drill manufactured by Guanghe Machine Tool.

II. Core Equipment Advantages: Perfectly Suited for Machining High-precision Auto Parts

Independently developed and produced by Guanghe Machine Tool, the ZK2102*500 CNC deep hole gun drill is a star product in China’s deep hole processing sector. It is professionally designed for machining small-diameter, high-precision and ultra-deep holes, fully matching the processing scenarios of core automotive components.

· Processing Capacity: Drilling diameter range: φ3–20mm, maximum drilling depth: 600mm. Equipped with double spindles to realize synchronous rotation of workpieces and tools, ideal for deep hole machining of slender shafts and disc parts including gearbox shafts, fuel injection nozzles and connecting rods.

· Machining Precision: Stable machining accuracy up to IT7 grade, surface roughness Ra≤0.4μm, straightness within 0.1mm per meter. It can effectively correct tiny aperture errors and satisfy strict requirements for sealing and transmission performance of auto parts.

· Intelligent Configuration: Fitted with high-end domestic CNC system; servo spindle maximum speed reaches 8000r/min with stepless speed regulation. It adopts high-pressure internal cooling chip removal system to solve chip evacuation difficulties in deep hole machining. Featuring automatic feeding, positioning and clamping, it supports one-click full-process operation with high automation level.

· High Efficiency & Durability: Adopts cemented carbide gun drill bits with excellent wear resistance and impact resistance, with single-edge service life up to 15–20 meters. Its processing efficiency is 3 times higher than traditional drilling machines, greatly cutting down single-piece production costs.

· Wide Compatibility: Capable of processing various common automotive materials such as 40Cr steel, stainless steel and aluminum alloy. It adapts to flexible production of multi-variety and small-batch products, well fitting the diversified production demands of Indian auto parts manufacturers.

III. Cooperation Significance: Sino-Indian Manufacturing Joint Efforts to Empower Indian Automotive Supply Chain Upgrade

This procurement of Chinese ZK2102 deep hole gun drill sets an important benchmark for high-end equipment manufacturing cooperation between China and India. For Indian enterprise ACI, the new equipment enables independent precision machining of small-diameter deep holes, ending the reliance on imported high-end deep hole processing machines. It helps enhance product competitiveness and expand its business in the supply chains of new energy vehicles and global high-end automakers.

For China’s equipment manufacturing industry, this order further proves the worldwide recognition of Chinese CNC deep hole processing equipment. As a key domestic manufacturer specializing in deep hole machine tools, Guanghe Machine Tool has exported its products to more than 30 countries and regions across Europe, Southeast Asia and the Middle East. This latest cooperation in India further optimizes its strategic market layout in South Asia.

Industry experts pointed out that India’s automotive manufacturing industry is in a critical period of high-end and intelligent transformation, leading to a sharp surge in demand for precision processing equipment. Boasting outstanding cost performance, mature technology and customized services, Chinese deep hole processing machines enjoy strong market competitiveness in India. In the future, there will be broader space for bilateral cooperation between China and India in the field of auto parts machining.

IV. Future Prospects

Person in charge of ACI stated that the ZK2102 machine will be firstly applied to the production of motor shafts for new energy vehicles and fuel injection system parts for high-end fuel vehicles. The company plans to carry out in-depth cooperation with Guanghe Machine Tool in customized equipment development, technical training and joint research and development, so as to build a local demonstration production line for deep hole machining in India.

Guanghe Machine Tool promised to provide full-process technical support, installation & commissioning, operational training as well as 7×24-hour after-sales maintenance services. The company will also optimize equipment performance to adapt to local high-temperature and dusty working conditions in India, ensure stable and efficient operation of the machines, and help local customers achieve greater economic benefits.
