Fixtures are devices used to hold workpieces during the manufacturing process to ensure accuracy and repeatability. In the manufacturing process of the fixture, milling cutters and drills are two key cutting tools. They are used at different stages to make the structural and functional components of the fixture.
Use of milling cutter
Shape and surface processing:
In the initial stages of making the fixture, milling cutters are used to machine the contours and planes. This involves cutting out the basic outer frame of the fixture as well as flat or beveled surfaces.
Groove and recess machining:
The clamps have various slots and recesses in them to accommodate slides, rails or other fixing elements. A milling cutter is used in this step to precisely cut these specific shapes.
Special shapes and details:
For parts of the fixture that require special shapes or fine details, such as cams, recesses or bevels, specially shaped milling cutters can be used.
Use of drill bits
Hole processing:
Drill bits are mainly used for drilling holes in the process of making fixtures. These holes can be used for mounting setscrews, dowels, guide elements or for fixing workpieces with fasteners.
Thread processing:
After drilling, some holes may require threads to accommodate bolts or screws. Drilling is usually done using a tap, but preliminary hole machining still requires the use of a drill.
Deep hole processing and fine positioning:
For components that require deep holes or precise positioning, special attention must be paid to controlling the drilling depth and position when using drill bits.
Key considerations when using milling cutters and drills
Choose the right tool material: Choose the right milling cutter and drill bit material, such as tungsten carbide or high-speed steel, according to the fixture material (metal, plastic, etc.).
Adjust appropriate cutting parameters: including rotation speed, feed rate and depth of cut to achieve optimal processing efficiency and surface quality.
Use cooling and lubrication: Use an appropriate amount of coolant or lubricant during machining to reduce heat accumulation, improve cutting efficiency, and extend tool life.
