Wood Shaper: Features And Safety
A wood shaper, also known as a spindle moulder, is a stationary woodworking machine used for milling profiles on wood stock. Unlike metalworking shapers, wood shapers have a vertically oriented spindle that drives one or more stacked cutter heads. These cutter heads typically have three blades and turn at a slower speed compared to handheld wood routers.
Wood shapers offer several advantages over handheld routers, including:
- They can cut larger profiles
- They are capable of driving custom-made bits with unique profiles
- They have motors with 1.5 to 5 horsepower
Additionally, wood shapers run more quietly and smoothly and can run in reverse. They can also be adapted to perform specialized cuts using accessories such as sliding tables and interchangeable spindles.
Safety is a crucial aspect of working with wood shapers. They are equipped with a guard mounted above the cutter to protect hands and garments. Additionally, jigs, fixtures, and accessories such as featherboards can be used to prevent injury and optimize the quality of the cuts.
Types Of Shapers: Single Head Vs. Multi Head
There are two primary types of shapers: single head and multi head shapers. The choice between them depends on the specific requirements of the machining operation.
Single head shapers are less expensive and simpler to set up and run. They typically have a top head only, making them suitable for basic shaping tasks.
On the other hand, multi head shapers are equipped with multiple cutting heads, allowing them to process more work in a single pass. These machines can have up to four cutting heads, which can be arranged parallel or perpendicular to the table.
The choice between single head and multi head shapers depends on the complexity of the workpiece, the desired efficiency, and the available budget. While single head shapers may be sufficient for simpler operations, multi head shapers are more suitable for high-volume production or when multiple profiles need to be machined simultaneously.
Tooling For Shapers: Materials And Grades
Shapers rely on various types of tooling to perform cutting operations. Common types of tooling used with shapers include cutters, knives, blades, planer blades, and cutter heads. These tools are made from materials such as high-speed steel, carbide steel, aluminum, and regular steel.
The choice of tooling material depends on factors such as the hardness of the workpiece material, the desired finish, and the specific machining operation. High-speed steel is commonly used for general-purpose cutting, while carbide steel is preferred for harder materials. Aluminum and regular steel tooling can be a cost-effective choice for specific applications.
Additionally, tooling for shapers comes in various grades that offer different levels of hardness and durability. The choice of grade depends on the specific requirements of the machining operation, including the desired tool life, surface finish, and accuracy.
Shapers are versatile machine tools used in machining and woodworking operations. While they have been largely replaced by more advanced machines, they still have a place in many machine shops due to their simplicity and minimal tooling requirements.
