Cutting Edge Furniture Making – Haworth & Leitz Tooling Solutions

Haworth’s sustainable manufacturing practices help give the contract furniture giant an edge in the marketplace.

One of the top three U.S.· based contract furniture manufacturers, Haworth Inc. is renown worldwide for its quality office furniture and innovations. Founded in 1948 in Holland, Ml, by G.W. Haworth, it remains a family-owned and privately-held company serving markets in more than 120 countries through a global network of 650 dealers and 6,500 employees. 2014 net sales for the furni­ture giant were $1.8 billion.

Spurring the company’s success is its focus on research and design, which help drive the company’s deep understanding of agile workplace needs, said Haworth spokesperson Ryan McCall.

“Globally, Haworth improves workplac­ es with award-winning furniture, interior architecture, and technology solutions to help customers achieve business goals and transform culture, as well as support collaboration and innovation,” said Mc­ Call. “Haworth is committed to protecting and restoring the environment, creating economic value as well as supporting and strengthening its communities .”

As part of Haworth’s sustainable manu­facturing efforts, the company made changes to the production of its furniture and components. Among the technology upgrades in the panel processing area was the implementation last year of Leitz tooling to the edgebanding line.

“We upgraded our double-sided edge­ bander with the Leitz WhisperCut EdgeEx­ pert milling head program,” said McCall. “We were looking for a sizing tool on the edgebander that would greatly increase finished cut quality and greatly decrease the frequency of tool changes.

“Before developing this tooling program, machine operators were spending an aver­ age of 45 minutes every shift changing carbide insert tooling to maintain a quality cut. When we implemented the Whisper­ Cut EdgeExpert program, the PCD milling heads dramatically decreased the need for tool change frequency,” he said.

Feedback from the lead operator on the double-sided edgebander indicates he is now changing the diamond-tipped knives every six to eight weeks, McCall added.

“Work surface production was specifically targeted with this tooling development. We manufacture over 1,200 rectangular work surfaces per day with standard color offerings or a customer’s own material,” he said.

In addition to the edgebanding pro­cess, a number of machines are integral to the production of Haworth’s wide range of products. Among the workhorses in use at the company’s factories are beam and angular saws for cutting panels and sheet goods to size. Laminating is done in-house, utilizing a hot platen press. CNC routers and machining centers are also used extensively within the production area as the furniture manufacturer continuously looks for ways to improve the productivity and profitability of its products and processes.

The Leitz Tooling program is an integral part of this goal. “The WhisperCut EdgeExpert ROI is well under a year based on labor savings alone,” McCall said. “We have had great success with this tooling program.”

Tooling Spotlight: ProfilCut Q Insert Tooling System

In our tooling spotlight, we break down what you need to know about our most popular tools. This month’s MVP is the Profil Cut Q & ProfilCut Q Premium.

The Tool

ProfilCut Q, ProfilCut Q Premium, and ProfilCut Q PCD are the fastest and most precise dedicated profile insert systems available.  The ProfilCut family of tools is designed to optimize process efficiency through perfect cut quality, highest yield, and fastest production cycles.

What makes it better

  • Modular body design offers profile flexibility and economic operation
  • Precision knife locating and retention prevent knife movement due to centrifugal forces
  • All knife changes can be made at the spindle, without disassembly of cutterhead
  • Knife clamping elements are protected from dust & resin build-up for ease of maintenance
  • Longest service cycles with Marathon or TDC (diamond) coated, and RipTec knife options
  • Lightweight aluminum alloy body allows for better balance and, in turn, reduced vibration
  • Certified and approved to operate at knife velocities up to 120 meters per second (50% faster than any competing insert system)

When to use it

  • Five-piece cabinet doors (cope/stick/style/rail/edge detail)
  • Wood interior and exterior doors
  • Wood windows
  • Architectural millwork and mating profiles
  • Miter lock or v-folding applications
  • Finger and glue jointing applications
  • Profiling of non-ferrous metals and advanced materials

Suitable raw materials

  • Soft, hard and exotic wood species
  • Panel materials such as plywood, raw or laminated particleboard and MDF
  • Plastic, foam, resin and composite materials
  • Non-ferrous metals

The results

  • Perfect sand-free finish quality at high knife marks per inch
  • Prevention common defects such as grain plucking, tearing and fuzzing
  • Reduced scrap loss, rework, and post machine sanding and repairs
  • Exact profile dimensions are maintained with every knife change
  • Maximum tool life
  • Multiple profiles can be achieved through simple knife change or exchange of modular cutter disks
  • Reduced machine downtime, with no need for machine recalibration
  • Larger profiles and limited machine spindle wear
  • Lowest possible cost per unit of production
