Pneumatic Cylinders in Machine Tools
Pneumatic cylinders are commonly used to power the motion and clamping systems of machine tools like machining centers, lathes, mills and more.
Clamping Workpieces
One of the primary uses is for clamping and unclamping workpieces during machining operations. Pneumatic cylinders:
Clamp Workpieces in Place
Pneumatic cylinders actuate wedge clamps, roller clamps, vise jaws and other clamping systems to securely hold workpieces while they are being machined. The fast, consistent motion of pneumatic cylinders helps ensure workpieces are clamped tightly and accurately.
Unclamp Workpieces Quickly
When the machining cycle is complete, pneumatic cylinders are used again to rapidly unclamp the workpiece so the finished part can be removed and a new workpiece loaded. The fast cycle times of cylinders speed up these repeatable processes.
Opening and Closing Doors
Pneumatic cylinders are well suited for opening and closing machine tool doors during operations to enclose the workspace:
Safety Doors
Machine guarding doors are opened and closed with pneumatic cylinders to provide operator access while ensuring safe enclosure when the machine is running.
Chip/Coolant Doors
Doors that cover areas where chips and coolant collect are opened and closed with cylinders for easy cleanout between operations.
Positioning Cutting Tools
Pneumatic cylinders are also used to actuate the positioning and motion systems inside machine tools:
Extending/Retracting Spindles
Cylinders actuate the slides, ways and guides that extend and retract spindle assemblies carrying cutting tools.
Adjusting Worktables
Pneumatic cylinders actuate the slides and ways that position and adjust worktables, shelves and other work-holding surfaces.
Benefits for Machine Tools
The clean, consistent motion and simple design of pneumatic cylinders make them well suited for machine tool applications. Benefits include:
Precision
The ability to tightly control speed and stroke length provides the repeatable precision required for machining processes.
Durability
Pneumatic cylinders can withstand the harsh environments inside machine tools and chip-filled spaces.
In summary, pneumatic cylinder provide the reliable, repeatable linear motion needed for clamping, machining and safety systems in machine tools. Their clean design, simple maintenance and precision performance make them a mainstay of machine tool technology.
