Power and Stability
To provide stable footing–the key to optimum accuracy–the 54HH has a 21- x 13-inch (W x D), all-steel base cabinet that puts the table surface at a comfortable 32 inches above the floor. The one-horsepower, one-phase, 115-/230-volt motor (pre-wired for 115 volts) is factory-mounted within the base cabinet and can be converted to use 230-volt power. The motor is on a special mount for easy belt-tension adjustments, and the fine/quick adjustment lever on the infeed table ensures precision cuts.
The base also contains the dust collection chute that evacuates debris from below the cutterhead via the exterior four-inch-diameter port near the floor–a design that keeps the hose out of the way to prevent tripping accidents.
There are many cutterhead designs that carry the helical moniker, including simple straight blades broken into segments and dispersed around the cutterhead cylinder. Despite the helical label, they retain many of the liabilities of the long-blade designs. However, the 54HH features a true helical cutterhead with specially machined carbide inserts arranged in spiral-shaped rows for effective–and incredibly quiet–performance.
The inserts also have a four-inch radius ground into them and are mounted so they approach the wood at a 14-degree angle. This creates a true shear cut that eliminates much of the impact and the resulting fiber disturbance other cutterhead designs deliver. Also, the durability of the carbide combined with the low-impact, shear cutting action mean the inserts have an extended life.
Precision Ground Cast-Iron Tables
With a length of 66 inches and a width of 7-1/2 inches, the main precision-ground cast-iron table is one of the longest available in this class, providing plenty of support for large workpieces. It’s conveniently mounted on dovetailed ways that keep it perfectly aligned through height changes. Adjustments are easy: the outfeed table height is adjusted with a handwheel mounted below the table; to adjust the infeed table, the handle can be moved up and down for coarse height changes or, the long handle can be rotated to make fine, precise height adjustments.
High-Performance Fence System
The all-cast-iron fence system has a length of 38 inches, height of four inches–and like the tables–is precisely ground to ensure straightness. The supporting and tilt mechanism, made up of large cast-iron pieces, make this system as accurate and repeatable as it is durable. For versatility, the fence tilts up to 45-degrees towards and away from the tables.
Also, fully adjustable stops at 90 degrees (vertical) and each 45-degree position make set-up fast and help keep the 54HH accurate with minimal maintenance, while center-mounted controls make for easy operation.
The 54HH is backed by a five-year warranty.
