The selection of CNC tool holders depends on the requirements of the machining process. Different machining methods require different CNC tool holders, which should be selected correctly based on the machining capabilities of the machine tool, the properties of the workpiece material, the machining procedures, cutting amounts, and other relevant factors. The principles for selecting CNC tool holders are: good rigidity, high durability, and high precision. Under the premise of meeting machining requirements, it is advisable to choose shorter tool holders to improve the rigidity of CNC tool holder machining. According to the cutting motion method and the corresponding blade shape, the application of CNC tool holders can be divided into three categories: 1. General CNC tool holders, including turning tools, planing tools, milling cutters (excluding shaped turning tools, shaped planing tools, and shaped milling cutters), boring tools, drill bits, reamers, and saws, etc.; 2. Shaped CNC tool holders, where the cutting edge has the same or a similar shape to the cross-section of the workpiece being machined, such as shaped turning tools, shaped planing tools, shaped milling cutters, pullers, conical reamers, and various threaded machining CNC tool holders, etc.; 3. Tools for machining gear tooth surfaces or similar workpieces, such as hob cutters, slotting cutters, shaving cutters, conical gear planers, and conical gear milling cutter discs, etc. When selecting CNC tool holders, the size of the CNC tool holder should be compatible with the surface size of the workpiece being machined. In production, for machining the peripheral profile of flat parts, vertical milling cutters are often used; when milling flat surfaces, tool holders for hard alloy blade milling cutters should be selected; for machining bosses and grooves, high-speed steel vertical milling cutters should be chosen; for machining rough surfaces or rough holes, corn milling cutters with hard alloy inserts can be selected; for machining some three-dimensional profiles and variable angle contours, tool holders for ball end mills, ring mills, conical mills, and disc mills are commonly used.

The milling process directly achieves perfect finishing and quality, which was unimaginable in the past. However, with the design of modern machine tools and tools, this has become a trend in the industry. In an increasing number of precision machining applications, there is no need for grinding, polishing, or etching after milling. In these applications, the engraving machine tool holder system plays a significant role. It ensures tool rotation accuracy, compensates for vibrations, and guarantees precision on the geometric reference surface and perfect machining surface quality. Now, let's take a closer look at the role of the engraving machine tool holder!

The spindle of the engraving machine serves as a bridge in mechanical processing by connecting the machine spindle and the tool, functioning from top to bottom. The main characteristics include the performance, torque, and speed of the spindle, which are output through the tool holder. This indicates that the tool holder can be installed with tools to achieve normal processing. Now, let's explore the role of the engraving machine spindle in CNC processing!

In machining factories, tool holders and tool clamps are primarily used in CNC machining centers for processing key components such as molds, inserts, and copper sheets. The quality of the mold cores and inserts directly determines the quality of the molded parts.

Types of knife handles and knife clamps
In addition to being maintenance-free and resistant to dirt, the handle is easy to use and securely clamps the tool. The stress-lock type knife handle uses a multi-faceted tool tightening method, which has a very simple structure, but the design system functionality is also quite advanced for the clamping device.

The introduction of knife handles and knife clamps.
The main difference between it and the previous two knife handle clamps is that the knife handle clamp does not use a thin-walled structure, and an intermediate cone sleeve has been added to the conical surface of the knife handle clamp.

Some common knowledge about thermal expansion of knife handles, explained by the knife handle and knife holder manufacturer.
The manufacturers of tool holders and tool clamps believe that in recent years, high-speed machining technology has been widely promoted and applied in the fields of parts processing and mold manufacturing. At the same time, high-speed machining machines have higher requirements for the corresponding tool clamping technologies and equipment (such as tool holders, etc.), and there are also high demands for dynamic balance.

Some knowledge points about thermal expansion of tool holders, as told by tool holder and tool clamp manufacturers.
The manufacturer of tool holders and tool clamps believes that heat shrink tool holders utilize the principle of thermal expansion and contraction. By using a thermal induction device, the clamping part of the tool is heated in a short period of time, expanding the inner diameter of the tool holder, and then the tool is immediately loaded into the tool holder. When the holder cools and contracts, it provides a uniform clamping force. There are no mechanical clamping components between the tool and the tool holder, which can address critical issues such as balance, runout accuracy, and clamping strength in high-speed machining.

The characteristics of thermal expansion tool holders, explained by the tool holder and tool clamp manufacturer.
The manufacturer of tool holders and tool clamps believes that the value of tool holders is relatively small compared to complete sets of equipment, but they are an important bridge connecting the machine tool spindle and the cutting tools. With the large-scale application of high-speed processing equipment and the gradual increase in spindle speeds, choosing the right tool holder has become particularly important.
