Tool Holder: Types, Applications, and Selection Tips for Machining Tools

A key component connecting the machine tool spindle and cutting tools, used for transmitting torque and positioning accuracy. Common types include ER collets (elastic design, wide clamping range, ±0.01mm precision for light machining), hydraulic chucks (high rigidity, vibration resistance, suitable for high-speed cutting up to 50,000rpm), and milling chucks (high-precision radial runout ≤0.005mm for milling).

Advantages of the product

Multi-Material Compatibility

Suitable for a wide range of cutting tools, from HSS drills to carbide end mills. ER collets accommodate tool diameters from 0.5mm to 32mm, while milling chucks support heavy-duty cutting of stainless steel and titanium with radial loads up to 8kN.

An angle head is a versatile machine tool accessory designed to redirect the cutting axis of a spindle, enabling machining operations at specific angles (commonly 90 degrees) in confined spaces or on complex workpieces. This adaptability makes it indispensable in industries such as aerospace, automotive, and mold making, where components like engine blocks, turbine blades, and die cavities require features machined on multiple faces without repositioning the part. Constructed from high strength cast iron or alloy steel, angle heads are engineered to maintain rigidity under cutting loads, with precision bearings and gears ensuring minimal backlash (≤0.001mm) for accurate positioning. Their transmission systems, often utilizing bevel gears or synchronous belts, transmit torque efficiently, allowing spindle speeds up to 15,000 RPM for high speed machining of materials like aluminum and titanium. Key design considerations include modular interfaces (compatible with CNC milling machines and lathes), adjustable angles (some models offer 360 degree rotation), and integrated coolant systems to support continuous cutting. WondersunM’s angle heads feature hardened and ground gear sets for quiet operation and extended service life, with sealed housings to protect internal components from coolant and chips. They are available in various sizes, from compact units for micro machining to heavy duty models for large scale milling, with customization options for spindle tapers and tool clamping mechanisms. Compliance with ISO 9001 ensures consistent quality, while on site technical support helps optimize setup for specific applications, enhancing productivity by reducing part handling and setup times.
