From Novice to Master
A basic requirement for any tool shop. A metal hammer makes a great beginner’s project as well. A simple, mallet-type head is straightforward to make, and the tapered handle offers more of a challenge. The hammer can be modified as needed; you could make just the handle for a rubber mallet, or a ball-peen hammer for a different shape. A

CNC Milling is an automated process used to manufacture 2D and 3D parts by removing material from raw stock. To make a CNC milled part, a block or sheet is placed on a table below a spindle which holds a cutting tool. A computer controls the tool used, the rotation speed and the vertical motion of the spindle, and the horizontal motion of the

Ball mill
Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:−2 or 1:−1). The grinding balls in

Milling Finish: Complete Guide [ Tips, Techniques, and Secrets ]
The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip, the diameter on the ball gets smaller and smaller, finally going to zero. As a result, the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut. Be sure to keep this in mind when using one. If possible, use

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size. The large balls tend to break down the coarse

Two fluted end mills can be used to plunge into work like a drill. End mills with more than two flutes should not be plunged into the work. Ball end mills can produce a fillet. Formed

11 Ways to Locate Part Zero on Your CNC Machine
To use this method, put your part in the milling vise or fixture. You’re typically going to make the corner part zero. Since you’ll be starting (usually) with unmachined material, it’ll be important to leave some allowance for machining in your CAD drawing. So, part zero sits in space rather than actually being on the part.

How to Drill Ball Bearings (with Pictures)
Swap out the drill bit for a ball mill (of the same diameter of your ball bearings) or a larger drill bit. Drill a shallow hole into the plate. The hole should not be deeper than the radius of the ball. Test fit the ball to make sure it seats well in the hole, but doesn''t sit below the equator of the ball.
