CNC milling machines are a cornerstone of modern manufacturing, shaping and refining metal, plastic, and other materials with unmatched precision. But what exactly is a CNC milling machine, and how does it work? How does it differ from other CNC machines like lathes? More importantly, what are the key components that make it function so effectively?

At its core, CNC milling is a subtractive machining process that uses rotating cutting tools to gradually remove material from a workpiece. These machines are widely used across industries such as aerospace, automotive, medical, and precision engineering. With advancements in technology, CNC mills now feature multi-axis capabilities, automatic tool changers, and advanced cooling systems—enhancing efficiency and accuracy like never before.

Understanding the parts and components of a CNC milling machine is crucial for anyone involved in manufacturing. In this guide, I’ll break down the essential elements that keep these machines running smoothly, from the spindle and worktable to the control system and cutting tools. Whether you're new to CNC machining or looking to deepen your expertise, this article will give you a comprehensive overview of CNC milling machine components and their functions.

How Does a CNC Machine Work? 

A CNC (Computer Numerical Control) machine operates by following pre-programmed instructions to precisely cut, shape, or engrave materials such as metal, wood, plastic, and composites. The process begins with a CAD (Computer-Aided Design) file, where engineers or designers create a detailed 2D or 3D model of the desired part. This digital blueprint is then converted into G-code using CAM (Computer-Aided Manufacturing) software, which translates the design into specific commands that control the CNC machine’s movements. Once the program is loaded into the machine’s controller, the operator secures the raw material onto the machine’s worktable and selects the appropriate cutting tool. When the CNC machine begins operating, it moves along multiple axes (X, Y, and Z for basic machines, with additional A, B, and C axes for more complex ones) to follow the programmed path with extreme precision. High-speed motors, ball screws, and advanced sensors ensure accurate positioning and smooth operations. Depending on the type of CNC machine, whether it’s a milling machine, lathe, router, plasma cutter, laser cutter, or even a 3D printer; the tool either removes material (subtractive manufacturing) or adds material (additive manufacturing) to shape the final product. Throughout the process, automated monitoring systems track the machining progress to ensure consistency and quality. Once machining is complete, the part may require additional finishing processes such as sanding, deburring, or polishing before undergoing a final quality inspection, often using coordinate measuring machines (CMMs) or laser scanners to verify accuracy. CNC machines revolutionized modern manufacturing by providing high precision, repeatability, and efficiency, making them essential in industries such as aerospace, automotive, medical, and electronics manufacturing.

Preload adjustment of ball screws is a key step to ensure their high precision, high rigidity and long life. The role of preload is to eliminate the gap between the ball and the raceway, reduce the reverse clearance (backlash), and improve the axial rigidity and vibration resistance of the system. However, excessive preload may cause heating, increased wear and even jamming, so the adjustment must strictly follow the technical specifications. The following are the detailed methods and precautions for preload adjustment:

1. Purpose of preload adjustment

Eliminate axial clearance: Ensure that the screw has no empty stroke when moving forward and backward.

Improve rigidity: Enhance the system's ability to resist deformation due to load changes.

Extend life: Reasonable preload can evenly load the ball and avoid local wear.

Reduce vibration and noise: Reduce impact and abnormal noise caused by clearance.

2. Main methods of preload adjustment

a. Double nut preload method (most common)

Principle: Apply opposite axial forces through two nuts to squeeze the ball into contact with the raceway.

Steps:

Install double nuts: Install two ball nuts in reverse on the same screw shaft.

Apply preload: rotate the two nuts to bring them closer together, compress the elastic element in the middle (such as a disc spring) or directly lock them through the thread.

Adjustment method:

Torque control method: tighten the nut to the specified torque value with a torque wrench (refer to the manufacturer's data).

Displacement control method: measure the distance between the two nuts and adjust to the preset compression amount (usually 1%~3% of the lead).

Lock the nut: use a locking washer or thread glue to fix the adjusted position.

b. Shim adjustment method

Applicable scenarios: single nut structure or occasions where the preload needs to be accurately adjusted.

Steps:

Add a shim between the nut end face and the mounting seat.

Change the axial relative position of the nut and the screw by increasing or decreasing the thickness of the shim, and compress the ball and raceway.

The preload needs to be tested repeatedly until the target value is reached.

c. Spacer adjustment method

Principle: add a spacer (sleeve) of a specific length between the double nuts, and control the preload by changing the length of the spacer.

Advantages: High preload accuracy, suitable for equipment with high rigidity requirements (such as CNC machine tools).

Steps:

Measure the original spacing between the two nuts.

Calculate the required spacer length based on the preload amount (usually the required compression amount = spacer length - original spacing).

Install the spacer and lock the nut.

d. Variable lead method (preload type ball screw)

Principle: The manufacturer changes the lead of the ball circulation path to make the ball preload in the nut.

Features: Users do not need to adjust, and can obtain standard preload by direct installation (need to select according to the load).

3. Key parameters for preload adjustment

Preload level: usually divided into light preload (C0/C1), medium preload (C2/C3), heavy preload (C5), which needs to be selected according to the load and accuracy requirements.

Preload amount calculation:

Preload amount ≈ 0.05~0.1 times the elastic deformation corresponding to the rated dynamic load.

Empirical formula: preload = (5%~10%) × lead (refer to the manufacturer's manual).

Preload detection indicators:

Axial rigidity: The displacement after applying external force must be less than the allowable value (such as 1μm/N).

Reverse clearance: measured with a micrometer, the target value is usually ≤5μm.

IV. Detection and verification after adjustment

Torque test:

Manually rotate the screw to feel whether the resistance is uniform and avoid local jamming.

Use a torque meter to measure the driving torque and compare it with the manufacturer's recommended range (re-adjustment is required if it exceeds the limit).

Reverse clearance detection:

Fix the micrometer contact to the nut, move the screw in the forward and reverse directions, and record the displacement difference.

Temperature monitoring:

Run without load for 30 minutes to check whether the temperature rise is normal (generally ≤40℃).

V. Precautions

Avoid over-preloading: Excessive preloading will cause a sharp increase in friction heat, accelerated wear and even sintering.

Lubrication management: After preload adjustment, it is necessary to add an appropriate amount of grease. It is recommended to use high-speed and high-load lubricants.

Environmental adaptability: The preload amount needs to be re-checked in high or low temperature environments (affected by the thermal expansion coefficient of the material).

Regular maintenance: Check the preload status every 300-500 hours of operation and readjust it if necessary.

VI. Common problems and solutions

Problem 1: Large running resistance after preload adjustment

Cause: Excessive preload or insufficient lubrication.

Solution: Reduce the thickness of the gasket or the length of the spacer sleeve and increase lubrication.

Problem 2: The reverse clearance still exceeds the standard

Cause: The nut is worn or the screw shaft is bent.

Solution: Replace the nut, straighten the screw or replace a new screw.

Problem 3: Abnormal noise and vibration

Cause: Uneven preload or broken balls.

Solution: Readjust the preload and check the ball circulation system.

Hydrocracking bubbling bed technology is an advanced petroleum refining process specifically designed for the deep processing of heavy oil and solid-containing petroleum products. As global conventional crude oil resources gradually deplete, and the trend toward heavier crude oil becomes increasingly evident, hydrocracking bubbling bed technology is playing an increasingly critical role in the energy industry. This technology addresses the dual challenge of global energy shortages and the need for improved energy efficiency, particularly in the context of rapid economic growth in developing countries and the resulting surge in energy demand. Below is a detailed explanation of the hydrocracking bubbling bed process, its key equipment, and industrial applications.

1. Working Principle of Hydrocracking Bubbling Bed Technology

Hydrocracking bubbling bed technology is based on hydrocracking reactions aimed at breaking down large molecular organic compounds in heavy oil and solid-containing petroleum products into smaller, lighter hydrocarbons through the combined action of catalysts and hydrogen. This process improves oil quality, reduces sulfur, nitrogen, and oxygen impurities, and enhances the fluidity and combustion properties of the final product. The core of hydrocracking lies in using hydrogen under high-temperature and high-pressure conditions to cleave large molecules into smaller ones, ultimately yielding high-quality light oil products.

In a bubbling bed reactor, hydrogen is injected at the bottom, mixing with the heavy oil and catalyst to form a fluidized, bubbling state. Due to the extended contact time between the catalyst and the feedstock in this gas-liquid-solid three-phase system, efficient hydrocracking reactions can occur. This technology is especially effective in processing high-sulfur, high-nitrogen, and other impurity-laden feedstocks while significantly improving yield and economic performance.

2. Role of Circulation Pumps (Ebullating Pumps)

Circulation pumps, also known as ebullating pumps, are essential components of the hydrocracking bubbling bed system. Their primary function is to ensure the continuous circulation of feedstock and catalyst within the reactor, maintaining uniform temperature distribution and a stable reaction environment. By circulating the feedstock, the pump ensures thorough contact between the oil and catalyst, thus improving reaction efficiency and preventing localized overheating or catalyst deactivation.

Additionally, circulation pumps help control the reactor's pressure and flow, ensuring the continuous flow of the oil feed. Given the harsh operating conditions in hydrocracking (high temperatures, high pressures, and the presence of solid particles), these pumps must be designed with high resistance to wear, corrosion, and thermal stress. They must also withstand prolonged exposure to extreme conditions while ensuring system stability and efficiency.

3. Process Advantages and Application Fields

Compared to traditional catalytic cracking processes, hydrocracking bubbling bed technology offers several notable advantages:

• Wide Range of Feedstocks: This technology can process a variety of low-quality feedstocks such as heavy oil, residual oil, kerosene, and solid-containing petroleum products, offering strong adaptability.
• High Product Yield: The hydrocracking process efficiently breaks down heavy molecules, increasing the yield of light oil products and resulting in higher overall output than conventional methods.
• Environmental Benefits: The hydrocracking process effectively removes harmful impurities such as sulfur and nitrogen, reducing the pollutant content in the final product and meeting stricter environmental regulations.
• Improved Energy Efficiency: By converting heavy components into more combustible light oil products, hydrocracking significantly enhances energy utilization efficiency.

The application conditions of hydrogenation boiling pumps are complex, the medium temperature is as high as 500℃, the inlet pressure is 30MPa, and the medium is highly corrosive. At present, the technology of this product is only mastered by a few countries, and there are very few factories that can produce it, and it is expensive. Fortunately, Huasheng is one of the very few factories that can produce this pump.

In 2018, Huasheng Pumps and Valves undertook the "Residue Oil Hydrogenation Boiling Pump Research and Development" project, a major equipment localization project of Sinopec Headquarters. The company relies on the operating parameters of Sinopec's 2 million tons/year liquid diesel hydrogenation unit for research and development. Its rated flow rate: 835m³/h, head: 79m, temperature: 410℃, wet motor power: 250kw. It took 4 years, and the product was delivered in 2022 and is currently running well. The success of the project has enabled China to break the foreign monopoly on hydrogenation boiling pump technology and reduce costs.

As global energy structures shift and environmental requirements tighten, hydrocracking bubbling bed technology presents significant growth potential. Key future development trends include:

• More Efficient Catalysts: Research and development of more efficient, longer-lasting catalysts will further improve reaction efficiency and product yield.
• Intelligent Control Systems: The application of advanced automation and data analysis technologies will optimize the reaction process, reduce energy consumption, and enhance system stability.
• Expanded Application Range: With ongoing technological advancements, hydrocracking bubbling bed technology is expected to extend into other unconventional resource processing areas, such as coal-to-liquids and oil sands extraction.

The development and application of hydrocracking bubbling bed technology provide an effective solution for the utilization of heavy oil and solid-containing petroleum products. This technology offers a viable path for addressing the depletion of conventional oil resources while meeting the growing demand for energy. Circulation pumps, as a critical component of the process, play a pivotal role in ensuring the success of the entire operation. Looking ahead, as the technology continues to evolve, hydrocracking bubbling bed technology will remain a key player in global energy production and refining, contributing to the sustainable development of the energy sector.
