The Whitney 3400HXT Combination Machine Tool uses the fastest technologies to make parts – Punching and Plasma Cutting.

The Whitney 3400HXT Combination Machine Tool uses the fastest technologies to make parts – Punching and Plasma Cutting.

• Punched holes provide accurate internal features.
• It is faster to punch holes than to pierce and contour holes with plasma or laser.
• External features are plasma cut. Advanced plasma-cutting technology provides highly productive contouring (much faster than laser) with high quality.
  • Small kerf angle (vertical cuts)
  • Dross-free cutting

• Additional features such as forming (countersinks, tread plate, louvers), drilling and tapping can be added to eliminate additional downstream operations, allowing parts to be completed in a single operation.

Manufacturing costs are lower using the combination machine technology.

• Labor costs are lower because it takes significantly less time to manufacture the parts.
• Operating costs are lower.
• Amortization of capital costs is significantly lower since
• Lower initial capital cost than laser
• Faster cycle time – Cost of capital per fabricated part is lower because capital costs are amortized over more fabricated parts.

The PROFIT-DOUBLER

• Higher profit per part —lower overall cost per piece gives a higher profit margin per piece.
• More parts generating profit—more parts are produced (in the same amount of time) on a combination machine, so there are more parts generating profit than on the other technologies.

55 TON PUNCHING CAPACITY

IMPORTANT NOTE: Punching of high tensile material is a special application for Whitney Combination Machine Tools and may void the machine warranty and cause premature tooling wear. High tensile strength material is defined as any material whose tensile strength is greater than 60ksi (413 MPa). Materials often referred to as “remnants” or “seconds” will often randomly exhibit tensile strength greater than 60ksi (413 MPa) and thus will void the machine’s warranty. WHITNEY reserves the right to have a representative sample of customer supplied material mechanically and/or chemically tested. If processing high tensile material, please consult the factory for a review of your specific requirements. In some cases, a larger Whitney Combination Machine model could be recommended.
