If your plastic has a low melting point, a Single Flute Plastic Cutting End Mill is a good option. This tool has a larger flute valley than its two flute counterpart which allows for bigger chips. With a larger chip, more heat can be transferred away from the material without it melting. For plastics with a higher heat tolerance, a Two or Three ...
Acrylic can be cut using CNC mills or CNC lathes. CNC lathes are generally used for softer materials like wood, foam, plastic, and aluminum, and rotate the part using a stationary tool. A CNC milling machine is very precise because it uses a multipoint cutting tool that can move along different axes. This presents you with a variety of angles ...
Ball End Mills (Ball Nose) Ball end mills, or ball nose end mills, are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multidimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool.
2. Nylon 66. Nylon, also known as polyamide (PA), is a broad category of lowfriction engineering thermoplastics with high impact strength, high abrasion and chemical resistance, and overall excellent mechanical properties.. Nylon 66 is particularly wellsuited for CNC machining because it's strong and durable enough for a wide variety of applications in many industries including automotive ...
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

Why Flute Count Matters. One of the most important considerations when choosing an end mill is determining which flute count is best for the job at hand. Both material and application play an important role in this critical part of the tool selection process. Understanding the effects of flute count on other tool properties, and how a tool will ...
Hi All, I am looking for a comprehensive guide on how to set my Spindle speed, Feed Rate and Plunge rate for various materials or as a rule of thumb, how these figures vary between MDF, Softwoods and Hardwoods. I don't have many bits at the moment, but while playing with the ones I do have, I tried moving from MDF to Hardwood pieces but am unsure how to adjust my speeds and feeds. As an ...
A lightweight alternative to glass balls, acrylic balls maintain clarity over time. They are scratch and UV resistant, so they stand up to outdoor use better than polycarbonate.

The mill and tram are more than 100 years old; the mill was built in 1910 and the tramway in 1913. The tramway at the museum is a replica; originals remain in the mountain.
What is stepover: Stepover is the distance your CNC machine moves your bit after each pass in the XY plane, measured as a percentage of the tool diameter.; How stepover affects surface finish: Smaller stepovers result in smoother surfaces and more details, but also longer machining stepovers result in rougher surfaces and less details, but also faster machining time.
Here are a few suggestions: The stepover should be between 1/3 and 1/10 of the tool diameter. Use a larger stepover, in the 1/5 to 1/3 range, for soft materials that cannot hold detail well. Use a smaller stepover, in the 1/5 to 1/10 range, for hard materials or materials that can hold significant detail like metal and jewelers wax.
A C T F =. 1 sin ( K a p r) For other shaped (like Ballnose, Round inserts, etc.), visit our Chip Thinning Calculator. Calculate the Feed per Tooth, based on the Chip load and Chip thinning factors: F z = C L × R C T F × A C T F. Calculate the RPM from the Cutting Speed and Cutter Diameter: n = V c × 12 π × D.
