Tooling Spotlight: ThermoGrip® Tool-Holding System

In our tooling spotlight, we break down what you need to know about our most effective tooling solutions. This month’s MVP is ThermoGrip CNC Tool-Holding System.

The Tool:

The Leitz ThermoGrip® heat-shrink tool-holding system offers unrivaled precision. The one-piece chuck design eliminates excess tool run-out common to collet and hydro tool-holding systems. Heat shrink technology allows for higher machine output, while yielding optimized cut quality and significantly extended tool life.

Heat shrink chucks offer the simplest and most rigid link between the machine spindle and cutting tool. Heat shrink chucks are inexpensive, one-piece tool holders, without moving or mechanical parts to wear or maintain.leitz, thermogrip, tooling, woodworking toolsThe ThermoGrip® tool holding system uses an inductive heating concept to provide stronger, more concentric tool clamping. This leads to increased tool life, better surface finishes, and improved cost efficiency.

What makes it better:

  • Highest torque transfer; essentially a one-piece tool and HSK-F63
  • Safe, rigid balanced to 36,000 RPMs
  • Optimized tool performance, finish quality
  • Increased cutting speeds (by 30%)
  • Improved machine productivity
  • Compact, solid design with no wear parts; right or left rotation
  • Easy cleaning/maintenance; unlimited lifespan
  • Reduced tooling costs; fast tool changes

When to use it:

With CNC and other precision machining.

The results:

The annualized savings utilizing Leitz ThermoGrip can be astounding. You will reduce tooling costs by a minimum of 25% and increase machine and operator productivity by at least 20%. ThermoGrip users have noted annualized savings of at least $15,000 per shift, with expanded production capacity. The ThermoGrip system generally pays for itself within months, and the maintenance-free chucks provide virtually unlimited service life.

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.”
