If you want to produce high-quality machined parts with a sleek appearance, it’s essential to consider some critical factors related to CNC machining.

CNC machining encompasses a variety of tools used in different capabilities. Without proper understanding, it can be hard to understand using the tools. An example of such tools is the CNC fixture, also known as CNC work holding fixtures.

You can also say CNC work holding fixtures reduce the amount of effort human exerts in a manufacturing process. With this, many will compare them to jigs. However, they are different. A jig works to guide the cutter’s movement. However, CNC workholding fixtures do not guide cutters. They only secure, support, and stabilize the workpiece during the manufacturing process.

One thing that makes spiral cutters popular is the extended use you get from not having to replace the cutters as often as you do with blades. For instance, when a blade becomes nicked, you have to replace the entire blade. However, if a cutter insert becomes nicked, you replace only the nicked insert, and not the undamaged ones.

A special fixture is a CNC fixture ideal for a particular workpiece. When used with this particular workpiece, they offer a load of advantages in terms of stability. There is also a quicker operation and convenience during use.

Universal CNC fixtures are usable on any workpiece with ease in adjusting them. Each part of the fixture is adjustable and replaceable to suit any workpiece. Like its name, universal fixtures have a very wide scope and applications.

Briefly, a straight-blade cutterhead consists of two or more blades (often called knives) spaced apart on a rotating steel head.  Spiral cutterheads consist of small square cutters placed close together in a spiral pattern on a rotating steel head. Both straight-blade and spiral cutterheads remove surface wood when a board passes over the rotating head.

The smaller cutting heads on the spiral cutter work in smaller sections to remove large quantities of surface wood. This results in a smoother wood finish than you’d get with blade cutters, reducing the need for additional sanding or finishing. The smaller cutting width also produces smaller woodchips, making it less likely you’ll clog the dust collection system.

When the need comes to replace a cutter, simply remove one screw, put on a new cutter, replace the screw, and you’re ready to go. It’s that easy. There is no need to calibrate the cutter height as you do after replacing blades. It’s one of the maintenance advantages of spiral cutters.

When classifying based on CNC operations, there are five types of CNC fixtures. Below is a little introduction to the CNC fixtures.

Their major difference is in their main functions where a Jig works to guide the cutter’s movement. A CNC fixture, however, does not guide a cutter. It only secures, supports, and stabilizes the workpiece during the manufacturing process. When the CNC fixture is used, the tool must also move when the workpiece moves. With jigs, the tool is always stationary.

Drilling is a popular process in the manufacturing process, and it is more popular in CNC machining. It simply means making a hole in a workpiece. CNC fixtures used in CNC drilling are called CNC drilling fixtures.

Inserts for roughing to semi-finishing face milling machine cutters on cast iron and steel components.

Straight-blade cutters have been around longer on DIY machines but spiral cutters are  growing in popularity. More manufacturers are starting to offer both blade and spiral cutterheads. Even so, not all manufacturer's straight-blade and spiral cutterheads are the same.

Using the CNC fixture or getting to know the right CNC fixture design comes with understanding many things. Below are some things to know whether you already have a cnc fixture plat or you need a custom CNC fixture.

CNC work holding fixtures use these two properties in their functions. For example, positioning and clamping play a major production role in the automotive industry. There, they secure and guide vehicles through the welding and assembly process.

Combination fixtures come in different sizes and shapes. They are ideal for handling many workpieces of different sizes and shapes based on the machine tools.

Maybe you’re ready to buy your first jointer or planer, or perhaps you’re thinking of upgrading to a newer one. If so, you may be wondering if you should purchase one that has a spiral cutterhead or a straight-blade cutterhead. Well, we’ll help you decide by looking at some of the details that set them apart.

Also, with CNC work holding fixtures, the tool moves when the workpiece moves. With jigs, the tool is always stationary.

The best definition to give a CNC fixture is that it is an agent of stability and positioning. It is a work-holding device with wide uses centered on securing, supporting, or mounting a workpiece correctly on the CNC machine.

You can categorize CNC work holding fixtures based on their uses. CNC fixtures under this category are of five types. Below is a little introduction on the five.

Generally, you can reach a valuable conclusion on CNC fixtures based on CNC machining operations. Every CNC machining operation that requires the need for a fixture has the name of the operation. Therefore, you can have others such as CNC honing fixtures and CNC lapping fixtures.

It is used in CNC milling, CNC turning, CNC planning, CNC slotting, and CNC grinding. This will also lead to the types of CNC fixtures which we demystified below.

An assembled CNC fixtures can only arise after considering a workpiece. The fixtures are according to the requirement of such workpiece. The assembling is via a special method. Depending on the need you can remove or reuse them when necessary.

So, does all this mean spiral cutters are better than straight blade cutters? Not necessarily. While it’s true spiral cutters have some maintenance and operational advantages, you can’t ignore the price advantage of straight blade cutters. With that in mind, for the novice woodworker or someone on a budget, straight-blade cutters can be the perfect solution.
