Understanding the metal cutting tools types available on the market is essential for manufacturers and workshops aiming to improve efficiency and product quality. This guide outlines the primary categories of metal cutting tools and offers clear guidance on when to choose each type, helping you make informed decisions for your machining and fabrication needs. Hunan Tangli New Material Technology Co., Ltd. specializes in providing a comprehensive selection of cutting tools tailored to diverse industrial applications, ensuring you get the best tool for every task.
When discussing metal cutting tools, they fall into two fundamental families: single-point tools and multi-point tools. Recognizing these groups helps streamline the selection process based on your machining goals, material properties, and desired finish.
Single-point cutting tools use one main cutting edge to remove material. The classic example is the turning tool, commonly used on lathes. These tools excel in shaping cylindrical parts by cutting away material as the workpiece rotates. Single-point tools are prized for their precision and control, especially for internal or external turning, boring, and facing operations.
Typical use cases include producing shafts, pins, and other rotationally symmetric components. Their main strengths lie in the ability to produce smooth finishes and close tolerances on one workpiece at a time. They also allow easier control of cutting parameters such as feed rate and depth of cut. However, they can be slower than multi-point tools for removing large amounts of material and often require more frequent tool adjustments or replacements due to localized wear on the single cutting edge.
Multi-point tools feature multiple cutting edges arranged around the tool body, which simultaneously engage the material during cutting. Common examples include milling cutters, drills, and circular saw blades.
These tools are versatile for a wide range of machining tasks, such as slotting, drilling holes, and cutting flat or contoured surfaces. Their multiple cutting edges enable faster material removal and improved heat dissipation, increasing productivity. The distributed cutting forces reduce wear on individual teeth, extending tool life. However, they may sacrifice some surface finish quality compared to single-point tools and sometimes require more complex machine setups, such as CNC milling machines or drill presses.
Mechanical cutting tools are the backbone of most metal fabrication shops. Below are key mechanical tools, their characteristics, and typical applications.
Saws use toothed blades to cut metal by a series of rapid, successive bites. They are ideal for cutting raw stock into manageable sizes and work best on medium to thin materials.
Common blade choices include high-speed steel (HSS) and carbide-tipped teeth, with options depending on the metal hardness and thickness. For example, a carbide circular saw blade is perfect for cutting thick aluminum profiles with speed and precision. The choice of blade tooth geometry also impacts cutting speed and surface finish. Bandsaws and cold saws are popular variations used depending on the specific cutting needs.
Drills create round holes by rotating a multi-point cutting tool against the workpiece. They work well for metals of varying hardness and thickness, from thin sheets to thick plates.
Twist drills with HSS or cobalt alloys are standard. Specialized drill geometries, such as split-point or parabolic flute designs, enhance chip evacuation and reduce heat buildup. A practical example would be drilling mounting holes in steel furniture frames, where hole accuracy and clean edges are essential.
Milling cutters feature multiple teeth that rotate to remove metal from flat or contoured surfaces. These tools excel in shaping complex geometries and slots.
Carbide inserts are popular for milling tough materials like hardened steel. Milling also allows a range of operations including face milling, peripheral milling, and slotting, adapting to diverse manufacturing needs. A typical scenario includes milling slots on aluminum profiles used in window and curtain wall frames, where both precision and surface finish matter.
Lathes employ single-point tools to machine parts by rotating the workpiece against a stationary cutter. They are essential for cylindrical parts production.
Commonly used carbide or HSS tools can produce smooth finishes on shafts and pins. Lathes also allow threading, grooving, and taper turning, expanding their functionality beyond basic shaping.
Grinding tools remove metal by abrasion using a rotating wheel embedded with abrasive particles. They are best for finishing and sharpening tools or parts requiring tight tolerances.
An example is precision grinding of circular saw blades to restore sharp edges and maintain cutting efficiency. Grinding can also achieve surface finishes unattainable by conventional cutting, making it indispensable for final finishing.
In addition to mechanical methods, thermal and energy-based cutting tools offer advanced options for precision and thickness ranges difficult to achieve mechanically.
Plasma cutting uses a high-velocity jet of ionized gas to melt and blow away metal. It is ideal for cutting thick metals quickly, with moderate precision.
This method suits industries like shipbuilding and heavy machinery fabrication but may cause heat-affected zones, which are a limitation for heat-sensitive materials. Recent advancements have improved cut quality and reduced dross, making plasma cutting increasingly popular.
Oxy-fuel cutting burns metal using a combination of oxygen and fuel gases. It is cost-effective for cutting very thick steel plates but less suitable for thin or non-ferrous metals.
Commonly used in construction and heavy equipment manufacturing, it offers deep cuts but lower precision compared to laser or plasma. It also requires skilled operators to ensure safety and quality.
Laser cutting employs focused light beams for high-precision cuts on thin to medium thickness metals. It produces clean edges with minimal heat impact.
Laser cutting is preferred in electronics, automotive, and aerospace industries for intricate designs and fine tolerances. Its ability to cut complex shapes with minimal secondary finishing reduces production time.
Water-jet cutting uses a high-pressure stream of water mixed with abrasive particles to cut metal without heat. This makes it perfect for heat-sensitive materials or composites.
It is widely used for cutting aluminum profiles and delicate parts requiring no thermal distortion. Its versatility extends to cutting a variety of materials beyond metals, such as glass or stone, broadening its industrial applications.
EDM removes metal through electrical sparks between an electrode and the workpiece. It is used for extremely precise cuts on hard metals or complex shapes that are difficult to machine mechanically.
Industries like mold making and aerospace rely on EDM for high-accuracy components with complex contours and fine details. EDM is especially useful for hard materials like tool steels and superalloys.
Choosing the right metal cutting tool depends on several factors, including the material, thickness, tolerance, finish, speed, and budget.
Material type: Hardness and composition affect tool choice, for example, carbide tools for hard alloys.
Thickness: Thicker materials often require thermal or mechanical saws.
Tolerance: High precision favors laser or EDM.
Surface finish: Grinding or single-point tools can offer smoother finishes.
Speed & throughput: Multi-point tools and thermal cutters generally increase speed.
Cost: Mechanical cutting tools usually have lower initial costs, while energy-based tools may require more investment but lower labor costs.
Thin stainless steel sheet → Laser cutting for precision and clean edges.
Thick structural steel plate → Oxy-fuel or plasma cutting for fast, deep cuts.
Aluminum profile → Carbide circular saw blade or water-jet cutting for minimal distortion.
Hardened tool steel part with complex geometry → EDM for precision and surface finish.
