Unique cuts with sleek designs enable you to achieve artistic results. Working with thick plates often requires precise techniques. Bevel cutting is one of the fundamental techniques for producing exquisite products with smooth edges. It is employed in various industries for manufacturing numerous products.
In this blog post, you’ll explore creating a bevel cut. You’ll also learn about the benefits and various applications of the bevel cut. So, let’s get into it.
What is a Bevel Cut?
A bevel cut is an angled cut made at an angle along the edge of the material. The angle between a material’s edge is 90° to its surface. However, in bevel cut, the cutting angle is less than 90°, creating a slop on the material. The cutting angle between the edge and the material’s surface depends on your project’s specifications. Usually, this angle is 45°. However, bevel angles can be less or greater than 45°.
According to the Hunker, you can create bevel cuts through various tools, including a circular saw, table saw, miter saw, jigsaw, or router. You can make this slopped cut along the edge or entire side of the working plate.
In heavy-wall tube processing and heavy industrial manufacturing, professional tube cutting machines such as the Baison G24CP and K12CP adopt a factory-proven, high-efficiency configuration of “vertical cutting head + harmonic reducer + servo motor”. This enables them to flawlessly achieve ±45° bevel cutting and V/Y-type groove processing, directly providing precise weld penetration and structural strength assurance for subsequent multi-pass welding.
This cost-effective structure not only delivers exceptional swing angle precision and reliability, but also makes it the ideal choice for international distributors looking for high-volume wholesale and heavy-duty tube processing.

Techniques for Bevel Cutting
Bevel cutting is a vast practice that employs various techniques. The following are some useful techniques to get a perfect bevel cut:
1. Manual Bevel Cutting
Manual bevel cutting employs hand-held tools, including grinders, hacksaws, or chisels. It is a basic technique, and you don’t need heavy machinery or software. The precision of this technique depends on your cutting skills.
You also need to be cautious, as any mistakes can lead to severe injuries and damage your workpiece. A significant drawback of manual cutting is that it is time-consuming and can only be used for small projects.
2. Portable Bevel Cutting
Portable cutting is the most widely used technique. It employs various portable cutting tools, like circular saws, miter saws, and table saws, to create bevel cut on metal or wood plate. This technique gives you more consistent and smooth cuts than manual cutting. However, you need to invest in quality tools and blades for the best results.
3. Automatic Bevel Cutting
Automated cutting uses computer-aided machinery. The machinery employs special software for optimal operation. This technique is used for large-scale industrial projects. It enables you to make multiple bevel cuts simultaneously, saving time and increasing efficiency.
Moreover, it is a safer technique as it eliminates and minimizes the risks of damage due to manual handling. However, automatic bevel requires significant investment in machinery and software.
4. Plasma Bevel Cutting
Plasma arc cutting is another popular technique for cutting metal plates. This technique is perfect for cutting hard materials and thick plates. Plasma-cutting employs ionized gas to cut metals.
This technique also employs automation to increase precision, making it ideal for industrial use. However, this method generates heat and fumes and requires proper ventilation for safety.
5. Laser Bevel Cutting
Laser cutting uses intense laser beams to cut metals, wood, and other materials. This technique produces precise, clean cuts for materials that are hard to cut with traditional techniques. As the laser beam falls onto the material, it melts and vaporizes, resulting in a smooth cut. Laser cutting also minimizes wastage as it focuses on a specific material area.
6. Water Jet Bevel Cutting
Water jet cutters employ high-pressure water streams to cut material. It is also a great way to cut thick plates and hard-to-cut materials. This technique is also safe as it utilizes regular water and does not produce heat or fumes.
7. Ultrasonic Bevel Cutting
The ultrasonic cutting technique utilizes high-frequency vibrations to create smooth bevel cuts. However, it is not suitable for thick materials. It best suits thin and delicate materials, like glass and ceramics. This technique is widely used on an industrial scale to produce small, intricate parts.
The Benefits of Bevel-Cut Thick Plates
Bevel cutting is a precise technique and offers several advantages. Here are some benefits of using bevel cutting for thick plates:
1. Better Structural Strength
Structural strength is a paramount factor for fabricating a perfect end product. Irregularly cutting a workpiece can reduce strength, leaving you with a weaker product. Bevel-cutting thick plates eliminate this issue by evenly distributing the tension on the material. It minimizes the stress in weak points and creates a stronger overall structure.
2. Improved Joint Stability
Creating strong and seamless joints is a fundamental requirement for many industries. The inclined surface increases the joint surface area. It offers better connection, resulting in enhanced adhesion and joint stability. Furthermore, the smoother cut edges make joining pieces easier without gaps.
3. Aesthetic Design
Bevel cuts are known for providing precise and clean edges. It adds a touch of elegance and enhances the overall aesthetic of the workpiece. According to SAWINERY, bevel cutting can effectively hide the seams of two different parts. You can use this technique to give your product a professional look.
4. Minimal Material Wastage
Various cutting techniques result in significant material wastage, especially when working with thick plates. Bevel cutting offers efficient utilization of material by cutting a slop edge. It removes less material from the sheet and increases the yield of your production process. It is a useful tactic if you are dealing with expensive materials.
7 Steps to Bevel Cut Thick Plate
In the V/Y-type 45° bevel processing of medium-to-thick plates above 20mm, due to the extended kerf (optical path increased by approximately 41%) and gas flow diffusion, it is extremely easy to cause poor bottom slag discharge. Through long-term debugging, the Baison workshop has summarized the following seven core steps to ensure a clean groove cross-section free of dross:
1.Drawing Analysis & 3D Linkage Parameter Preset Import the 3D CAD NC program and set the 45° axis linkage swing angle. Reserve compensation for thick plate thermal deformation and calibrate the dynamic zero point of the rotation center in the CNC system.
2.Material Identification & Surface Pretreatment Clean the surface scale and rust on carbon steel or stainless steel thick plates above 20mm to prevent impurities from causing local absorptivity unevenness, which can lead to arc breakage or blowouts at the groove root.
3.Large-Caliber Dedicated Nozzle Selection & Capacitance Calibration
Replace with large-caliber dual-layer or dedicated bevel-cutting nozzles suitable for thick plate bevels, strictly execute multi-point calibration of the capacitive sensor, and ensure the absolute spacing stability between the nozzle and the plate surface in a tilted state.
4.Deep Fine-Tuning of Focus and Assist Gas Pressure (Core Challenge)
Workshop exclusive experience: When performing 45° bevel cutting on 20mm+ thick plates, the beam penetration path is lengthened. At this point, the focal length must be appropriately lowered (adopting a deeper negative defocus) to converge energy to the middle and lower parts of the plate thickness; simultaneously, increase the pressure of combustion-supporting oxygen or high-pressure air by 15% to 25% (depending on the specific plate thickness), and coordinate with a high-flow nozzle to break through the resistance in the inclined kerf, thoroughly eradicating lower-edge dross.
5.Five-Axis Linkage Following System Dynamic Compensation
Activate Baison’s hardware combination of “vertical cutting head + harmonic reducer + high-precision servo motor” to real-time monitor and dynamically compensate for capacitive height drift during inclined cutting, ensuring that the nozzle does not collide with the plate and remains distortion-free at the 45° limit position.
6.Slow Start & Arc Initiation Power Optimization
Set a low-speed slow start and a pulse power ramp-up curve at the bevel starting point to prevent edge collapse or ablation of the 45° sharp edge (corner) due to excessive heat concentration during initial piercing.
7.Dynamic Trajectory Cutting & Section Squareness Quality Inspection
Observe the spark spatter trajectory during the cutting process (ideally, sparks should be concentrated downward in a beam shape). After cutting is complete, spot-check the blunt edge size and squareness of the cross-sectional V/Y-type bevel, and proceed to mass production only after standards are met.
The Application of Bevel-cut Thick Plate
Bevel-cut thick plates are employed for various purposes. Here are some applications of bevel-cut thick plates:
- Metal welding often requires smooth surfaces and perfect angles at the edges to create perfect welds. Bevel cuts offer you the right angles at the point of joining. According to the Timber 2U Direct, bevel cutting is a necessity for carpentry and joining materials.
- The woodworking industry also employs bevel cuts to create unique frames and furniture. You can create aesthetically pleasing products by using bevel cuts.
- The construction industry also relies on bevel cuts to fabricate strong and stable structural joints.
- It is also used for remodeling and renovation purposes. Cutting thick plates with bevel angles allows for precise fitting of materials, resulting in a seamless finish.

Thick Plate Bevel Cutting Common Problems and Solutions
In the large-angle (±45°) bevel cutting of thick plates (such as 20mm to 50mm carbon steel/stainless steel), due to highly concentrated laser energy and lengthened cutting paths, it is extremely easy to trigger excessive heat input and stress concentration. The Baison 12000W large-size beveling machine has perfectly overcome this persistent industry challenge through a unique software-hardware collaborative design:
- Angular Deviation and Edge Warping Caused by Excessive Heat Input
- Problem Analysis: When traditional equipment performs high-power bevel cutting for a prolonged period, heat continuously accumulates locally in the plate, leading to internal stress imbalance and causing thermal deformation or angular distortion at the cut edges.
- Baison Solution: Relying on the Baison 12000W high-power platform, the bed adopts a high-strength graphite fireproof brick bedplate. Graphite material not only possesses extremely high high-temperature and ablation resistance, but can also rapidly absorb and block heat conduction in the cutting zone. Combined with zone-based intelligent dust removal and a strong cooling air curtain, it compresses the heat-affected zone (HAZ) to a minimum, completely preventing plate deformation and geometric angle deviation.
- Blackened Kerf Sections, Severe Oxidation, and Bottom Dross
- Problem Analysis: During medium-to-thick plate bevel cutting, the optical path increases. If the assist gas fails to effectively blow through the molten slag, it easily leads to bottom dross and severe oxidation/blackening of the kerf.
- Baison Solution: Introduces large-flow composite gas nozzles and dynamic focus real-time compensation technology, optimizing the filling and slag discharge efficiency of high-pressure airflow in inclined gaps. This ensures a clean cross-section with regular metallic luster, free of oxidation and blackening, meeting the standard for direct fit-up and welding without grinding.
- Sharp Edge Ablation and Piercing Edge Collapse
- Problem Analysis: Due to the small metal volume and slow heat dissipation at the sharp corners of the bevel, over-burning and edge collapse easily occur instantly during the piercing phase.
- Baison Solution: Adopts Baison’s proprietary pulse power ramp-up and micro-speed slow-start algorithms, precisely controlling peak power at the moment of piercing to achieve a “cold-state” smooth entry, perfectly protecting the sharp corner profile of the bevel.
