TECH UPDATE

FINGER-JOINT EQUIPMENT

TECH UPDATE EDITOR: DIANE METTLER

AceCo Precision
Manufacturing

AceCo Precision Manufacturing’s innovations are continuing with the release of its next generation of fingerjoint cutters. After years of material research and investment in process technology, AceCo is now delivering among the most advanced finger-joint cutters in the industry, says the company. The cutter is designed specifically for significantly increasing production time between resharpening. Initial tests have indicated six to seven times the life of their normal cutters. These new cutters can be used in existing heads with no modifications and have the same precision tolerances as AceCo’s M2 steel cutters.

AceCo finger-joint heads are precision machined from 4150 heat-treated alloy to ensure the heads will remain within their original dimensional tolerances. The heads are also stamped with serialized numbers so that if the heads are sent back for inspection, the company can track data to compare their current state with their original high tolerance dimensions. Finger-joint heads are available with either collet centring devices or a hydro-locking system. And a finite finish guarantees thickness tolerance to be held to under +/- .0001”, which is at least twice as accurate as industry standard.

Conception R P

Conception is now proposing the complete “value-added’’ process manufacturing system: from the scanner to the CCS1000 automatic crosscut saw, then to the singulator (automatic short block infeed) through the wane-up system and the finger-jointer to the MSR tester.

The CCS1000—with an infeed speed of 1,000 ft/min (0 to 1,000 ft/min in 12 inches) and cutting speed of 350 cuts/min—feeds the singulator and runs the finger-jointer to 180 blocks/min. Different finger-jointing systems are offered from capacities of 12 press cycles/min (stop and go press) to 600 ft/min (crowder press) and finger-jointed planks from 20’ to 60’.

The precision end trim saws trim and cut the finger-jointed planks to the desired length with 1/64” precision. The MSR tester, with capacity of 1,000 ft/min, tests studs or flanges at each 2”.

Grecon

Grecon is part of the Weinig Group and offers a wide range of finger-jointing lines.

Grecon has recently developed the Combipact finger-jointing line. Specific quality requirements in the timber industry resulted in the new development of the Combipact. This precision machine can be universally used for vertical, butt jointing and jointing of special profiles. The individual sequences are short and transparent. The Combipact concept comprises a double milling unit (two opposing milling tools).

The company also offers the high-performance HS 120, a horizontal cutter, as well as the CF 300 for solid construction lumber.

Western
Pneumatics

The Machinery Group at Western Pneumatics has been designing, engineering and installing remanufacturing equipment for over 20 years. The company has taken the North American concept to horizontal finger-jointing and
enhanced it with quality machinery and state-of-the-art technology.

Their broad range of low-, medium-, high-, and heavy-duty high production finger-jointers allows the Machinery Group to accommodate the full need of its customers.

The heavy-duty high production finger- jointer from Western’s Machinery Group, known as the “HD High”, is the biggest short-block machine that Western manufactures. Manufactured with cast iron columns, this workhorse will definitely give operations the efficiency and production that they expect from a finger-jointing machine, the company says.

The material specifications for the HD High: Thickness, 5/8” to 2” (16 mm to 50 mm); Width, 1-1/2” to 8” (38 mm to 200 mm); Length, 4” to 36” (102 mm to 914 mm) narrow chains, 7-1/2” to 48” (190 mm to 1,219 mm) wide chain.

Doucet Machines Inc

The company offers three models of finger-jointing systems—the ZX-150, DJ- 250 and DJ-600. The ZX-150 is a high production unit designed for structural and non-structural applications as well as hardwood and softwood. The double end finger-jointer with lugs on 9” centre is a semi-automatic lug loader capable of feeding up to 150 pieces/min, and has a fully automatic corner transfer. It can finish lengths up to 40’ with a block thickness of 0.75” to 2”.

The DJ-600 is equipped to handle long stock 12” to 144”, with traverse bars on 9” or 12” centres. The fully automatic lug loader comes with singulator and optional inspection station. It will provide up to 600 linear ft/min. The fully automatic corner produces feed speeds of up to 1,200 ft/min and has a motorized feed wheel on top and bottom board.

The DJ-250 can handle stock 12” to 84”, with traverse bars on 9”, 12” and 18” centres. The DJ-250 includes a feed conveyor 60” wide, a 7.5 hp trim saw, five hp scoring saws and in-line glue applicator. It has an automatic assembly press capable of producing up to 250 linear ft/min.

Wisconsin
Knife Works

Wisconsin Knife Works continues its leadership in the woodworking industry as the industry has grown to expect more from tooling manufacturers. Its fingerjoint cutters can be made from M-2 or D-2 high-speed steel. In addition, WKW manufactures carbide-tipped and solid carbide finger-joint cutters, as well as the exclusive Opti-treated finger-joint cutters.

Perhaps 95 per cent of the solid wood finger-jointing done is accomplished using molybdenum tool steels such as M- 2. This tool steel is especially well suited for natural woods. The make-up of the M-2 alloy offers the ultimate in grindability, edge retention, and resistance to abrasion and corrosion. Other alloys are available, and may be necessary in certain applications, however, M-2 remains the best choice of tool steels for natural wood finger-jointing.

The Opti process produces an ultrahard surface on the cutter. Unlike some other coatings, Opti will not chip, peel,
or flake off. Extremely long run-times may be obtained under certain circumstances.

A check with WKW on specifics can determine whether these cutters are correct for a particular operation. Man-made materials such as LVL, plywood, particle board, MDF, and other products containing glues or other nonwood products are much too abrasive for tool steel or OPTI cutters. Solid carbide and carbide-tipped cutters are often the answer to these problems.

Sunhill Machinery

Sunhill Machinery has been importing quality woodworking equipment since 1979. By working directly with manufacturers, professional grade machinery is produced according to industry standards and customer requirements. Kikukawa, which Sunhill Machinery represents, is one of the most intelligent and innovative equipment manufacturers in the industry. Kikukawa is recognized for producing among the very best woodworking machinery in its class since 1897, says Sunhill.

Kikukawa builds a fully automated lug system finger-joint system that is extremely fast and is capable of producing at a maximum of 120 cuts/min. This system includes an automatic dual finger shaper with two scoring saws and two trim saws, an auto feeder with a suction conveyor belt which feeds the gluing unit and servo-operated assembly press. The equipment is built to last a lifetime and serve the most demanding finger-jointing needs.

Coe Manufacturing

Coe Manufacturing designs and builds complete Mann-Russell finger- joint gluing lines that utilize the benefits of Radio Frequency (RF) curing. RF cured finger-joints provide the highest strengths possible because the glue is cured while end pressure is being applied on the joint. RF curing also allows for immediate surfacing and proof loading, which saves space and reduces manpower.

Coe Mann-Russell Finger Line designs are based on over 35 years’ experience in producing structural and non-structural end products. These products include glulam beam laminating, I-Joist flanges, long length dimension lumber and, recently, prefabricated roof truss members. In addition to the RF curing tunnel, Coe/M-R builds the infeed and crowder section, traveling cutoff saw, final trim and stacking, as well as a bending type proof loader and special design finger-joint shapers. Each component is tailored to meet individual production and flow plan requirements.
