Interior doors

Interior doors have a special place in interior design. They are the physical and aesthetic separation between rooms, designed to create a harmonious connection between the house and the furnishings. In addition, attributes such as a high-quality appearance, functionality and safety must be fulfilled. These high demands placed on interior doors are also reflected in their manufacture resulting in an accumulation of complex and technically demanding production processes.

Manufacturers of interior doors benefit immensely by working with Leitz as a production partner. The combination of innovative tool solutions and outstanding process support creates a level of added value in efficiency, quality and productivity, which is unique in the industry.

Sizing of interior doors is carried out in the through-feed technology with milling cutters, segment cutters or jointing cutters. The Leitz EdgeExpert range is available in the jointing cutter sector for demanding applications. In the stationary technology, Leitz offers an extensive range of shank cutters.

Sizing with jointing cutters

Most of the jointing work is carried out with diamond-tipped tools, which are specially adapted to the machining process.

For decors that are difficult to machine, Leitz offers the EdgeExpert tool programme, which is designed for maximum edge performance and ensures tear-free edge quality on both sides.

Sizing with hoggers

Sizing with hoggers is carried out with either segment hoggers or milling hoggers.

Leitz’s advanced hogger programme produces first-class cutting surfaces with high productivity and reliability. This is true even with more difficult to machine panels such as chipboard and increasingly thinner edge materials.

Sizing with shank cutters

In the area of shank cutters, the focus is always on increasing productivity and quality.

The Leitz product range offers the right tool for almost every requirement.

Depending on the specific requirements, the profiling of door sheets is carried out on different machines, such as through-feed systems, stationary machine technology, or table or profile milling machines.

Leitz has the best tools for every requirement and every type of machine, helping to ensure maximum economic efficiency.

Through-feed technology

In through-feed technology, mainly rebate cutters with diamond tipping are used.

Leitz adapts these tools to the customer’s individual machining tasks.

Stationary technology

For profiling and rebating of interior doors with single rebates, Leitz offers a standard range with rebate depths of 15 mm and 13 mm including variable rebate profiles.

Table and profile milling machine

When cutting door rebates and other profiles, Leitz’s tool solutions can be individually adapted to the customer's needs. Leitz offers an extensive range of standard tools for milling work on table milling machines.

Leitz offers numerous tool solutions in its standard tool programme for all common edge processing machines. The range is continually updated and supplemented with a multitude of innovative tool solutions.

Trimming

Depending on the material and thickness of the edge material, various types of trimming sawblades are used for edge finishing. Leitz trimming sawblades are characterized by their universal application but also by their innovative design, which helps to keep noise to an absolute minimum.

Edge trimming

Edge trimming is about speed and cutting quality coupled with the tool life and the efficiency of the tool system. To meet these requirements, Leitz offers a wide range of diamond-tipped tools with fixed cutting edges (which can be re-sharpened) or exchangeable replaceable insert systems in its standard program. A further enhancement in the superior performance of Leitz tools is the use of the i-System, which ensures efficient chip collection for perfect cutting results.

Profiling

Profile tools in edge processing have a direct effect on the quality of the finished product. Leitz offers a wide range of tools that meet these high-quality requirements. In addition to the required edge quality, the profile change is an essential component especially in small series or batch size 1 production. Here, too, Leitz has developed innovative solutions that can easily master these challenges.

Scrapers

The finishing of the edges using scrapers is the final step in the production of interior doors. They are responsible for that ‘perfect edge’ appearance and have a great influence on the overall aesthetic effect of the door. In addition to conventional scrapers, Leitz also offers specially ground scrapers with anti-white bevels.

Precise bores and cut-outs are required to produce interior doors. These include stepped hinge bores for screw-in hinges, hinge boring, cut-outs for the lock case, spy and lever handle holes as well as borings for glass cut-outs.

Leitz meets the specific requirements of the drilling and cutting sector with an extensive range of tools.

Twist drills

Solid carbide twist drills work quickly, accurately and cleanly. Twist drills ensure exact plunging, even on inclined surfaces, with 30 to 50 percent higher feed rates. Optimum chip ejection reduces faults of cycle times and downtimes.

For the production of stepped hinge borings, Leitz tools are available for all commercially available hinge systems.

The tools used in the production of cut-outs in the door sheet, such for lock cases, spy holes or handle holes, must be precise; vibrations and tear-outs at the edge can ruin the final product. Corresponding cutting tools from the Leitz range deliver every time due to their smooth running. In addition, the special Marathon high-performance coating significantly extend the tool life and performance of the cutter, further increasing productivity.

Cutting light apertures

For the production of light apertures, Leitz has a comprehensive range of special roughing and finishing cutters. As well as running extremely smoothly, these cutters have outstanding cutting quality. The Leitz cutting tools are also Marathon-coated, which significantly increases the tool life and performance of the tool.

The Leitz ProfilCut Q cutterhead is the perfect choice for the production of door linings and door claddings with rebate.

With the corresponding standard interchangeable profile knives, rebate cutting of 4-5 mm can be set. For other rebate thicknesses, such as 7 mm, 8 mm or 11 mm, Leitz offers individual special productions tools.
