The Right Tooling for High Output Stair and Hand Rail Production

Stair and Rail Insert Tooling

Stair and Rail Insert Tooling

Modern stair production is an evolving process. Production methods of standard, straight stairways have their challenges but typically pose no production difficulties when using the right tooling. When producing specialized curved or winding staircases, more advanced machinery and tooling is required. With the advent of 5-axis CNC machinery, this process makes these more difficult tasks much more effective.

 Whatever type of staircase is manufactured, GDP|GUHDO offers a wide variety of standard and custom tool choices. Beginning with the all-important machine connection, we offer standard precision collet chucks, collets and the even closer tolerance heat shrink and hydro chuck systems.  Depending on the material and construction method, tooling options can vary widely. For machining of string boards, steps and producing the required grooves and notches for the treads and risers, we offer solid carbide and replaceable insert router bits for roughing and finishing applications.

 For hand rail production, we again offer carbide tipped, and insert options.  Standard straight hand rails pose no production difficulties and may accept larger diameter tooling.  This application is ideal for profile insert tooling of which we offer an insert router bit designed to machine the most common profiles. This tool offers repeatability, improved tool life and due to the shear cutting angle, will produce an excellent finish quality!  Tooling for volute production requires a smaller diameter and may sometimes have to be carbide tipped as opposed to carbide insert as a result of diameter limitation.

Other tool offerings range from cutter heads for stringer production, fluting and carving tools for hand rails and balusters. For drilling, standard drills bits of varying diameters and lengths and custom one-step drill bits of holes with counter bores for wood plug insertion.  For answers to your questions and solutions to your problems, contact GDP|GUHDO!

Helical CNC Cutter with Reversible Insert Tips

Helical CNC Planer Cutter

Helical CNC Planer Cutter on HSK63F arbor

This helical insert cutter (Item# 4339.800.30) is ideal for trimming, jointing, rebating, hogging and copying operations on solid wood as well as composite materials. For use on all CNC machining centers, this cutter has a maximum rpm of 18,000 and it comes in 80mm diameter x 80mm cut length with a 30mm arbor and 8x2mm keyway as well as a spacer (1). (HSK or ISO/SK tool holder is sold separately). Special sizes can be manufactured based on customer needs.

The cutter body is made of a high quality, light metal alloy with hard-anodized surface and special convex ground reversible insert knives to provide an excellent surface finish. The insert tips overlap 75% of the cutting surface, thus providing an effective 3 wing design. The bottom of the cutter has 2 reversible spurs for clean corners on rebate cuts. The bottom of the cutter is recessed to accommodate the retaining screw so that the cutter cuts flush on the bottom.

  • Special advantages of this cutter include high chip removal rate and improved chip flow through the helically positioned cutting edges
  • Optimum division of cut and shear angles for high feed rates
  • Perfect finish, without leaving visible knife marks, due to the special convex ground solid carbide tips.
  • Reduced noise level through aerodynamic design
  • Great option for pre-cutting arches in window production and also very popular in stair production.
