What Is A Milling Machine?
Judging from you reading this buying guide I suppose you are new to the craft. But even if you are not, I’m going to explain what a milling machine is just in case.
A milling machine is a device used to make cuts on metal by the use of a rotating cutter having one or more cutting edges. It can be used to make flat or curved surfaces of various shapes with accuracy and fine finish. With proper attachments, it can be also used for slotting, drilling, gear cutting and to make a circular profile.
If you are a professional or hobbyist craftsman then a mini mill will allow you to design and produce small parts and pieces right in your garage.
How a Milling Machine Works?
The milling machine is used to cut, slot, and shape metal pieces. It is done by attaching a rotating cutter or other attachments with the spindle holder.
It is done by the three-axis movement most milling machines support. The table which is responsible for the X and Y-axis movement houses the metal piece to be cut. The spindle holding the cutter can be moved up and down for the Z-axis movement. All of these are done by the use of some leavers and wheels.
By manipulating the table and the spindle, the metal piece can be positioned as pleased. The cutter slowly chips away bits of metal when it is in contact with the metal piece allowing the user to cut and shape the piece as he or she wishes. This is the basics of how a milling machine works.
How To Use a Milling Machine?
Step 1: Wear Safety Goggles
When using a milling machine, you are going to have a barrage of mental dust hurdle your way. They can easily go into your eyes and nose which is probably not a good thing.
So, before you do anything grab hold of your trusty safety goggles and put them on. Obviously, you can’t work if you can’t see it.
Step 2: Attach The Proper Cutting Tool
There are all sorts of cutting and drilling attachments out there for attaching to your spindle. All of them are used to make a certain sort of cut. So, do a bit of research and find the best attachment to your work.
Check the instruction manual that comes with your milling machine to learn how you can change the cutting attachment. Also, there are plenty of YouTube videos to help you out in that regard. So, we are choosing not to elaborate.
Step 3: Fix The Vise On The Worktable
First, clean the vise and its attachment accessories. Then clean the worktable. Make sure there is no dust. Grab a sandpaper and lightly sand the table surface and the bottom of the vise. Now get some wd 40 or any other lubricant and apply a thin layer on the table and also to the bottom of the vise.
After lubrication is done place the vise on the table and also place the accessories for attaching. Grab a wrench and tighten one bolt. Now, install the indicator gauge to make sure your vise is properly place. Make necessary adjustments and then properly tighten the bolts to set the vise in place.
There are various types of vises out there. So, do some proper research before attaching your vise to the table.
Step 4: Clamp Down The Metal Piece With The Vice
Grab on to your metal piece and securely place it between the clamps of your vise. Screw the clamps shut and your metal piece will be tightly clamped in place.
Step 5: Positioning
There are all sorts of knobs and wheels to position the table and spindle. Use the two X and Y wheels on the bottom to properly position the metal piece. Then lock them into place.
Now, use the Z wheel at the side of the milling machine to properly place the cutter. There should be another smaller knob at the front for a more precise Z-axis movement. After, you have positioned the cutter lock it down.
Step 5: Start Cutting
After your metal pieces have been position start up the cutter and start cutting.
Types of Milling Machine
Altogether there are about 15 different types of milling machines. All of them can be grouped into 4 types. These are as follows –
1. Column and knee
- Plain milling machine
- Hand milling machine
- Omniversal milling machine
- Universal milling machine
- Vertical milling machine
2. Fixed bed
- Drum milling machine
- Rotary milling machine
- Tracer milling machine
- Profile milling machine
- Planetary milling machine
- Pantograph milling machine
- NC or CNC milling machine
Now, let’s discuss briefly on each type of milling machine.
1. Column and knee:
These types of milling machines are mounted on the knee-casting which is also mounter on the main columns vertical slide. These are mare for professional use in workshops.
- Plain milling machine: These milling machines are used to cut flat surfaces with the cutter axis being parallel to the surface about to be milled. The table feeding can be done either by power or hand. These are much stronger and heavier than hand milling machines.
- Hand milling machine: These are your basic type of millers. These are hand controlled and the cutter is held horizontally by the spindle holder. These are usually small in size and are intended to be used for small scale personal DIY projects.
- Omniversal milling machine: What is different in the case of omniversal milling machines compared to plain and hand millers in the additional 4th movement performed by the table. At the knee using a swivel arrangement, the table can be tilted in a vertical plane.
- Universal milling machine: Just like the omniversal milling machine the universal milling machine also has 4 movement directions. Various attachments can be used to enhance the capabilities of this milling machine.
This machine can produce spiral, bevel, spur, twist drill, milling cutter, reamer. Anything that can be done using a shaper can also be done with a universal milling machine.
- Vertical Milling machine: In this type of milling machines the spindle is positioned vertically to the table. This machine is specially designed for milling slots, flat surfaces, and grooves.
This milling machine may have the movement directions of plain or universal milling machines. But the spindle head is attached to the column which is vertical and can be spun at an angle. Some machines also offer the option to adjust the spindle up or down.
2. Fixed Bed:
The fixed bed milling machines differ from column and knee type with the table being directly mounted on a fixed bed. There are no provisions for vertical or cross adjustment. The movement of the table is restricted at a right angle to the axis of the spindle. Fixed bed mills are heavy, large, and have a rigid construction.
- Simplex: One spindle head
- Duplex: Double spindle head
- Triplex: Triple spindle head
Also known as Plano-miller the planner type millers are massive machines designed for heavy-duty work. They have adjustable spindle heads in the transverse and vertical direction.
This milling machine has a cross rail that can be lowered or raised carrying the cutters. It has the saddles and the heads which are supported using rigid uprights. The machine can work on a number of work surfaces due to this arrangement of driving several cutter spindles.
These milling machines have special designs for specific types of work. There are various sorts of special milling machines.
- Rotary milling machine: In these milling machines the table is circular in shape and it rotates to a vertical axis. This allows the cutter to rough out the workpiece and the other to finish it.
One of the advantages of the rotary milling machine is that the workpieces can be easily loaded and unloaded while the machine is running.
- Drum milling machine: This one is similar to the rotary milling machine with the difference being the table spins on a horizontal axis rather than vertical. The table of this machine is called a drum.
The cutters of this milling machine are mounted on the three or four spindle heads that rotate in a horizontal axis. They chip away metal from the workpieces. After one full cycle of the drum, the finished part is removed and new pieces are loaded.
- Tracer milling machine: Tracer milling machines are designed to make complex or irregular shapes of molds and dies. It is done by the synchronized movement of tracing elements and cutters. The oil relay system is energized by the movement of the stylus which operates the table’s main hydraulic system. This is called a servomechanism.
- Profile milling machine: Profile milling machines are given a template to duplicate. In this machine, the cutter can be adjusted horizontally and the spindle vertically. The movement of the cutter is regulated by a hardened guide pin.
The movement of the table and the cutter head follows the guide pins movement on the given template to produce the duplicate.
- Planetary milling machine: In these milling machines the workpiece remains stationary on the table. The cutter revolves around the workpiece to make a cylindrical surface on the piece either externally or internally. This machine can also be used for making external and internal threads.
- Pantograph milling machine: The pantograph milling machine uses a pantograph machine to duplicate a job. Usually, a reproduced piece tends to be smaller than the given template.
These milling machines are available in three dimensional and two-dimensional models. Three-dimensional models are used for copying contours and shapes of a workpiece. On the other hand, two-dimensional models are used to engrave designs or letters on a piece.
- NC or CNC milling machine: These are completely automated machines that use computerized automated control for milling workpieces. These are far more accurate and less time consuming then hand-operated milling machines.
A program is used to control the spindle movement in various directions and depths. Most commonly G-code is used. These days CNC or NC mills can have up to 6 axis of movement.
In the case of most CNC milling machines, the machine needs to be as big as or bigger than the workpiece. But recently much smaller three axis machines are being developed.
What to Look When Buying a Mini Mill?
Mini mills are a huge investment. Especially, if you are buying one for personal use. So, it is common sense that you should buy the affordable mini milling machine you can afford. But you need to learn what specifications and features to look for before you can choose a mini milling machine.
Well, it should be obvious that when you are buying something like a mini mill the more power it offers the better. A powerful mini mill can seem too costly at first. But trust us when we say that a more powerful mini mill will cut costs enough to make the extra hundred bucks worth it.
First of all, more powerful mini milling machines will be better at heat dissipation as better components are required to support the higher power. But this also means that you can work for longer. This is because every mini mill comes with its own emergency power cut-off system that cuts off power when the heat reaches dangerous levels.
So, buying a more powerful milling machine would be a good idea if you plan on doing a number of sequential cuts back to back. Even if the power cut off doesn’t happen the components will surely be damaged as lower power mini mills are usually built with lesser quality materials.
Having a more powerful mini mill will also save you a lot more time. Being able to do a lot of cuts without worrying about overheating, emergency cut-offs or component degradation will surely boost your workflow. If you are looking to buy a mini mill for using in a workshop then buying the Jet JMD-18 you can find with the highest power would be ideal.
So, when it comes to the power, we recommend you assess what kind of work you would be doing with the mini mill, how long would you be working on it, and whether you are buying one for personal or professional use.
The size of the mini mill should also be considered for choosing the best one. For casual hobbyists, a compact size might be desirable. And for the most part that should suffice. But mini mills are a device for which smaller isn’t always better.
The size of the mini mill may determine the size of the object you can work with. So, more professional users may require a larger mini mill with more versatility of use.
You should be checking the spindle clearance of your mini mill before buying. This is the distance between the table and the spindle of the mini mill. The distance is close to the maximum height of objects that can be work on with that mini mill. So, more spindle clearance is preferable for advanced users.
Checking the table size is also recommended while buying a mini mill. Having a bigger table will allow you to work with bigger objects. It will also allow you to clamp the smaller object more securely.
Extent of Movement
This one is an important feature that you should definitely check before buying. By extending movement we mean the distance at which the mini mill can move in X, Y, and Z planes. The more distance the mini can cover the longer cuts you will be able to do.
We do not think We need to explain why that is preferable. Especially for professional users the extra distance in all of these directions can come in pretty useful.
So, if you plan on doing a lot of complex projects that require advanced milling capabilities then make sure to check for how far the mini mill can move in all three directions.
Mini Mills can weigh hundreds of pounds depending on the model you buy. Yes, there are more portable options out there. But if you are looking to buy a professional-grade mini mill then you can throw portability out the window.
Before purchasing your mini mill make sure your workbench can support its weight. If it doesn’t you can always buy a custom-made stand from the company of your mini mill. They are specially designed to support that specific mini mill and sometimes come with a few useful features.
You should also look into buying a good shop winch if you are thinking of getting a heavy mini mill. This will provide you more versatility of use as you will be able to easily move the machine around your workplace. It is advised that you do not try to move a heavy mini mill without the necessary equipment as it may result in serious injuries.
If you don’t have the budget to invest in a shop winch then going for a lighter unit would be the ideal decision.
When you are cutting metal and drilling holes precision is of the utmost importance. And this is achieved by a great extent when buying large and heavy mini mills that do a great job of absorbing most of the vibration.
It is when using a smaller and lighter mini mill the real struggle begins. Milling with a small mini mill will cause more vibration leading to less precision. You might end up with jagged or curved edges when making cuts. So, make sure the mini mill of your choice has good anti-vibration facilities before making your purchase.
Last but not least the price is very important to consider when buying a mini mill. On one hand, not everyone has the cash to throw in hundreds to thousands of dollars. But on the other hand, buying a cheap mini mill may eventually cost you even more.
Cheap mini mill usually comes with low-quality materials and parts. So, it often that they break down and need repairs. Last time we checked there many mechanics who know their way around mini mills. So, finding a repairman can become a task of its own. The frequent repairs that are needed in the case of cheap mini mills can also cost you a hefty amount.
So, the best thing to do would be to buy a mini milling machine you can afford and hope for the best.
Safety Rules for Mini Mills
- Wear goggles before starting up the mini mill
- Makes sure no one else is near the machine besides the operator
- Make sure you keep your hands away from the cutting tool
