Why would I use a thin-cutting frame saw as opposed to conventional method of making veneer slats?
The thin-cutting frame saw is able to cut accurate veneer slats with less waste (up to 30%). For example, instead of getting 4 veneers out of a given block you may get 6 veneer slats, the number of slats produced will always depend on the size of the block being cut and the thickness of the slat being produced. This is especially important when cutting more expensive woods such as oak, mahogany, maple, cherry and other exotic species. The frame saw will produce a finish which is both accurate and ready for further processes such as face gluing for flooring, stiles & rails and other products. The traditional method of making veneer slats is with the use of a conventional band or re saw. Due to the inaccuracy and poor finish produced with a conventional band saw the parts produced required additional machining steps, in this case it would be sanding on both sides. This is of course time consuming and expensive due to the additional labor and process costs. Because there are no further machining operations required when using our thin cutting frame saw, the customer will save on labor and material. These saving are significant enough to make the thin cutting frame saw a necessary piece of machinery even for the smaller manufacturing shops.
What kind of industries use thin cutting frame saws?
Thin cutting frame saws are used in any industry that requires veneer slats. Any company that is cutting a veneer slat and wants to produce a slat with minimum waste of material and a good finish can use the frame saw. Some of the more common industries in which a frame saw can be found include door companies who are making engineered stiles and rails, companies who are making radial half rounds for windows and doors, flooring companies who are making engineered wear layers for flooring, furniture companies, musical instruments companies (ie, Guitars) and variety of other industries.

How is the Neva-Ogden frame saw user friendly to operate?
The Neva-Ogden frame saw machines open in the middle for safe and easy saw frame removal and saw frame loading. This system was developed to make it easier and safer for the operator to remove and mount the saw frame in and out of the machine. It only takes 3 to 5 minutes to change out a saw frame. On some other thin cutting frame saw systems, the operator must climb up on top of the machine in order to remove and mount the saw frame. This can be dangerous for the operator, unless a crane/hoist is installed above the machine or a walkway is built above the machine for your operators. It is recommended that you contact your local Occupational Safety and Health Administration (OSHA) for safety standards.

How can I prevent tear out on the bottom of the slats?
A standard feature of all Neva-Ogden Frame Saws is the adjustable chip breaker. The chip breaker is made out of phenolic and supports the wood from the bottom during cutting process. The chip breaker can be adjusted so that the saw blades cut into the phenolic support block, hence preventing the wood slats from chipping out on the bottom as the saw blades exit the bottom of the wood. Many other frame saw systems do not have this adjustable chip breaker feature. Without the chip breaker, the slats will often have splinters on the bottom and on occasion these splinters will jam in between the saw blades and cause the blades to bend. Bent blades will cause the veneer slats to be cut too thin or too thick, either of which will result in down time to change the saw frame and a loss in production.
What makes the feed system on the Neva-Ogden Frame Saw superior?
On our frame saw, all of the bottom feed rollers are driven. Some of the feed rollers on the top are also driven. On most other frame saw machines, only the bottom rollers are driven. Because our frame saw has top driven rollers, it allows for the machine to feed more effectively and smoother, without the wood hanging up.

How do I know what feed speed the machine is running?
Our Frame Saw comes standard with an electronic digital feed speed indicator. When the operator wants to go faster or slower, he simply turns a handle on the infeed of the machine and the feed speed is adjusted and is indicated on the digital display on the control panel. In order to adjust the feed speed on other systems, you have to turn a hand wheel which is located on the outfeed at the bottom of the machine near the floor. Because it is inconvenient to change the feed speed with other systems, operators using these frame saws are less likely to change the speed according to the wood height or wood species. This can result in less productivity.

How can I adjust the top feed roller height according to the width I am cutting?
Adjustment of the top feed rollers on our saw is done automatically. To make an adjustment of the top feed rollers from one height to another the operator simply presses a button on the control panel and the top rollers move up or down electrically. This system is the same system that was used for many years on molding machines. The automatic height adjustment takes only a few seconds and is very user friendly. On some other systems, each set of top idle rollers has to be adjusted manually via a wrench by the operator reaching to the top of the machine. This manual adjustment is extremely cumbersome, and can take as long as 15 minutes depending on the size difference needed.

How much HP/kW will I need?
The main up/down motor on our machine is 20 HP motor . This allows the machine to cut more veneer slats without overloading the motor. We are able to cut up to 40 slats in one pass one our frame saw. Most other frame saw systems only have 15 HP motors.
What kind of feed drive system is used?
The feed rollers on the top and bottom of the machine are driven via sprockets and chains. These parts are all encased in a sealed gear box which runs in oil. The gear boxes are virtually wear-free because they are not exposed to dust. On many other frame saws, the sprockets and chains are not enclosed and are completely exposed to dust and other contaminants. With this type of this exposure, the chains and sprockets dry up and need to be changed frequently.
How should the Thin Cutting Frame Saw be configured for feeding?
The Frame Saw comes standard with a center guide and side guide system. The center guide feeding system allows two blocks of wood to be fed through the machine at one time. A fence is mounted in the center of the feed rollers and wood is fed on either side of the fence, blocks of wood up to 2 1/2″ thick can be fed on either side of the fence. With the side guide system the fence is placed on one side of the machine, one block of wood up to 6″ wide can be run through the machine. There is also an optionally channel feeding system available where the feed system is partitioned with multiple guides, these guides are built according to the size of wood which is to be processed through the frame saw. For example if you was running 1″ thick blocks of wood the channel system would be partitioned so that you could run 5 blocks of 1″ thick material at one time. The channel system fits into the machine like a cassette, the entire channel can be installed and removed as one cassette. On average most Thin Cutting Frame Saws are fitted with the center guide system; mostly because it allows for the most flexibility of this system. Various wood block thicknesses can be ran on either side of the fence and the only change the operator must make is with the hold over roller from the side which presses the wood onto the fence in the middle. Adjustment of the hold over rollers takes only a matter of a few minutes.
