What is a Mini Mill Machine?
A mini milling machine is a tool designed to remove matter from solid materials such as wood or metal, though it’s not limited to just those. Typically a mill is a machine that includes a motor that turns a spindle; connected to that spindle is a cutter.
By changing the cutter on the spindle/milling head, you can change the behavior of the machine entirely; a simple cutter change will give you the ability to do:
Each of these is achieved through the spinning action of the spindle, which turns the cutter.
You move your worktable either across or vertically towards the spindle. By moving the headstock up and down, you accurately control how the material will be cut.
Some mini-mills also have adjustable speed controls, which allow you to regulate the spindle/milling head speed, resulting in a much more precise cut for the material you are working with.
At the end of the day, mills are versatile tools; they will help you with a variety of projects such as:
- Cutting gears
- Reshaping wood or metal
- Producing slots that are millimeter perfect
Things to consider before buying a mini milling machine
When we reviewed mini mills for this article, we went through a decent number of models. A lot didn’t make the cut. We’ll take you through our criteria when looking for only the best small milling machines.
Ultimately the products on this list have to fall into the category of small milling machines. When we think of small, we think of something that you can use at home or in your home shop, which you can transport with ease.
Home milling machines need to be moveable, right?
Some mini-mills weigh as little as 6 pounds, while others will come in at a few hundred pounds. Believe it or not, both of these are considered small-size.
The weight of the mini milling machine isn’t always determined by the size of the mini-mill. Two mini-mills can be the same size but have entirely different weights. The best mini milling machines will usually house a cast-iron worktop. Cast iron is rather hefty!
A heavier milling machine lasts longer and normally performs better than a lightweight mill. The weight, however, is a big consideration when it comes to considering the best mini-mills; the heavier the milling machine is, the more difficult it is to transport the milling machine. Not only that, but you also have to consider the place you intend to keep the mill. Can it handle the weight of the milling machine, or will the floor be damaged?
If you are looking for a tabletop mill, a light milling machine will most likely work best. However, if your tabletop can take a few hundred pounds (I sat on mine to make sure), you’ll be able to handle one of the heavier milling machines.
Vibration in your mini mill is the last thing you want, so it’s best to avoid any mini-mill that vibrates a lot. Why? Well, if you want a precise and clean-cut, vibration will make that a near-impossible task. Uniform cuts and hitting that depth just right are just next to impossible when the milling machine is overcome by its over vibration.
For us, the best mini-mills are those that are vibration-free.
When kind of pushes you towards the heavier milling machine models, as it’s the lightweight ones that tend to vibrate the most. The more intricate projects demand machines with all the features, which are free of vibration.
The spindle clearance refers to the distance between the spindle and the tabletop. This is an important metric as it determines the maximum height of the materials you can machine with your mill; it also determines the size of the cutters and end mills.
The bigger your table size, the better; why? Well, it gives you more working space, which is handy for dealing with larger projects.
Fine, you intend only to work on small projects; even so, a bigger table will give you more room for secure clamping of your projects, increasing the accuracy of the milling machines results.
Movement In All 3 Planes
When we mention the 3 planes, we mean the X, Y, and Z axes. For ease of operation, most milling machines will include hand wheels or cracks which allow you to move the worktable across the x and y-axis.
Some of the more advanced models are designed to allow you to move the worktable long the z-axis (vertically, up, and down), but the spindle head should move along the z-axis/vertical axis.
Having this level of control allows for longer single pass cuts, which results in better results and reduced effort.
Different Electric mini-mills will have different motor power needs. Some may need 110v and others 230v; some may even need triple-phase power. When purchasing a mini milling machine, pay close attention to its power needs. Ideally, you’ll want to match its needs to what you can supply.
You can get around electrical issues by getting an electrician to make alterations to your shop’s or garage’s power output. Only use qualified professionals!
Make sure you check the motor as well. The motor delivers the power, so how much can it deliver? The first figure you are looking to work out is the HP (horsepower) rating, usually 0.x, 1,2, and so on. A powerful motor will have a higher rating and produce more grunt.
There’s also the wattage, 150 watts is fine for those light-duty tasks, but if you are working on bigger or harder materials, you’ll want something that puts out at least 500 watts.
Finally, there’s the spindle speed. You’ll typically see a rating from 0 to 2000 RPM (Rotations Per Minute) speed range, or even 0 to 3000 RPM speed range. The higher the spindle speeds the machine can handle, the wider the rating of tasks it can achieve. Also, the higher the speed, the smooth the result.
Types Of Mini Milling Machine
There are a wide variety of milling machines on the market. Each type has its own specifications and uses. To make this section easy to understand, we’ll go over the main types of milling machines.
When looking at a milling machine, they’ll come in two major types. Vertical or horizontal mills.
Milling Machines Are Further Categorized Into These Classes:
Vertical Milling Machine
A vertical mill has a spindle set at a perpendicular axis to the worktable (a vertical orientation). The vertical orientation type of mill is perfect for making horizontal cuts in materials.
Horizontal Mill Machine
A horizontal mill has its spindle situated so that it’s horizontal to the worktable. This is the perfect mill for making vertical cuts on materials.
Ram-Type Milling Machine
The Ram-type milling machines have a spindle mounted to the top of a column, typically a cast-iron column. The idea behind these mills is that the cutter can be placed either forward or rearward horizontally to the workpiece.
Knee-Type Mill Machine
The knee-type mill has its projection in the middle; it looks like the knee or the mill, hence the name. It also tends to have a worktable that is adjusted vertically, which rests on a saddle that sits on the knee.
Bed type Milling Machine
With most milling machines, the worktable is situated on top, but the worktable is actually situated on the bed when it comes to bed-type mills. This type doesn’t have a knee, and the lack of a knee allows the worktable to move along the vertical plane.
How To Use a Mini Milling Machine?
Before we jump into this section head first, We’d like to point out that there are many different mini mill models out there, and each will come with its own instruction manual with specifics on how to use them.
Your user manual will have all the details you need including pictures and labels of all the parts of your machine; this will be the source of truth on how your machine functions and how to keep it functioning efficiently.
With that in mind, this information is for reference or guidance purposes only, and you should consult your mill’s manual for the best advice on how to use your small mill.
How to Use Mini Mill: A Generalized Approach
When it comes to using a mini-mill, it’s relatively easy compared to the industry-based milling machines. But before you get stuck in, there are some steps to follow regarding setup.
Setting up the machine for use
- Before you get started on your product, secure your workplace. This means removing any chips or burrs from the machine and its immediate area.
- Select the right milling cutter, choose a size that works for you, don’t go for a bigger size than necessary.
- Check all the parts of the machine have the right level of lubrication; you want the parts to move around freely while also maintaining the right level of drag.
- These days we have machines that have bi-directional settings, so check whether the spindle is set to work in a clockwise or anti-clockwise mode.
- Always feed your workpiece to the machine in the opposite direction to the rotation of the cutter.
- Never make changes to the machine while it is operating.
- Ensure that your workpiece is properly clamped; you don’t want any shaking or vibration in the machine table.
- Always use the recommended lubrication.
Now that everything is set up and you are ready to go, There are 4-types of milling processes that are generally used.
- Face milling – This is milling a flat wooden or metal surface that is positioned at a right angle to the cutter.
- Slab Milling refers to the process where your flat wooden or metal surfaces are perpendicular to the cutter.
- Angular Milling – When you deal with smooth or flat surfaces that are inclined to the cutting surface, this is called angular milling.
- Form Milling – This is when you are milling irregular forms or metal or wood.
Here Are 5 Easy Steps to Follow When Using a Milling Machine:
Step 1: Safety First
Protect your eyes. There will be a lot of material shatter, and you don’t want that to land in your eyes. So the best thing you can do is to put on a pair of safety glasses; if you are a day-to-day glasses wearer, get some that sit over or have prescription lenses, because no, your glasses are not good enough.
Protect your hands. We also suggest using gloves to protect your hands; if you are using a metal milling machine, the metal swarf is very hot, so gloves will prevent an accidental burn to your hands.
Also, when using any mini milling machine, keep your attention keen. Hands can and do get milling if caution is not taken.
Never try to tighten up the arbor nuts of your milling machine by turning it on while you hold a wrench.
Keep a smooth, clean, and soft cloth at hand to hold the cutter bits when you want to remove or install them.
Install the cutter last to avoid any costly mishaps.
Keep a brush or rake close at hand so you can quickly and easily clean away any chips from the workstation.
Make sure to use splash guards to avoid splashes of cutting oil. This seems minor but actually is the cause of severe accidents if precautions aren’t taken.
Before using your mini mill, make sure you’ve taken the time to learn how to operate it; this means reading the manual. It’s crucial to know how to use the various controls and the emergency shut-off.
Don’t alter the spindle speed during operation. Disengage the cutter from the workpiece first, then change the speed.
Keeps all parts of your body away from the cutter when it’s in use. Never attempt to touch a turning mill or workpiece during operation.
Use the handwheels to move the headstock or worktable if something needs to be moved.
Before making adjustments or measurements, make sure the machine has been turned off.
Step 2: Gather The Parts
Before you start milling a workpiece. Make sure to have all the tools and supplies you will need close by. This may include wrenches, T-Slots, an oiler, even the manual, should you need to look something up.
I also like to keep all the materials I’ll be machining nearby.
When you have everything laid out, you’ll save time by not looking for parts in the middle of your projects; this will help increase your speed and safety.
Step 3: Put On The Handles
This seems like a silly or even irrelevant step depending on your mill. But make sure the handles are connected and working before milling. You might need some wrenches to get this setup.
You can also connect the end mill or drill to the spindle during this time. Make sure you have the right cutter for the task at hand.
Connecting mills is usually straightforward, but check your manual if you have any issues.
Step 4: Locate The Dial And Switch
The dial might be on the front or on the side. The switch will start and stop the machine.
Before you turn on the switch and get the spindle spinning, turn the dial down to its lowest setting, the dial is used to increase and decrease the spindle’s speed; start low and increase to the speed you need.
Step 5: Set The Vise/Clamp And Have Fun
Once you’ve confirmed all is working properly and you are sure the spindle is spinning correctly, make sure the machine is off and then connect the vise.
There will be spaces set for you to connect fasteners onto your worktable that will hold your vise.
Use the vise to hold your material completely still.
You can now turn on the machine and set the spindle speed.
Using the handwheels, you can move the workpiece and headstock to make the cuts you need.
