EMO Preview : Economic Advantages with Form Tools

Paul Horn GmBH at EMO 2019
Hall 5 Booth A54

Turning with form tools allows customers to benefit from economic advantages in series production. Horn offers customised carbide form inserts based on the 117 tool system for machining diameters from 16 mm upwards on turning and mill-turn centres. The patented, precision insert seat of the 117 system guarantees high concentricity and minimal axial runout as well as high repeatability of insert exchange to within microns. The precision-ground cutting edges achieve a high level of accuracy and surface quality. Financial savings are achieved due to the possibility of re-tipping, lower tool costs and reduced machine downtime. The internal coolant supply to both cutting edges via the round shank cools the contact zone and carries the chips away efficiently.

Horn offers the tools in profile widths (w) of 16 mm, 20 mm and 26 mm. Special profiles are precision ground to suit the application. The maximum profile depth is tmax = 17 mm. The maximum profile width is w = 26 mm. The insert coating is specially selected for each application and is available for material groups P, M, K and N. The round shanks are available as standard with diameters of 16 mm, 20 mm and 25 mm in the A and E designs. All variants have an internal coolant supply.

In The Port Sequence Valves

Control Sequencing of Individual Devices

  • Installs directly into device port, requires manifold mounting.
  • Works with Top and Bottom Flange Swing Clamps, Link Clamps and High Capacity Work Supports.
  • Controls timing of individual devices on your fixture.
  • Each valve can be individually fine tuned from the factory preset.
  • True sequencing design allows full system pressure downstream of valve after opening.
  • Maintains pressure upstream while device actuates.
  • Three pressure ranges available with adjustability within each range.*
  • Can be added after the fixture is built to assure proper sequencing.
  • Use with single or double acting clamps;
    in clamp port, unclamp port, or both.
  • Internal reverse free flow check valve allows for faster return.
  • Accessories available; Pressure pre-set block and in-line adapter block.

* Number of sequences within each range depends on number of devices, pump flow & operating pressure.

 

In The Port Precision Flow Control Valve

Control Speed of Individual Devices

  • Use with single or double acting clamps.
  • Meter-in flow control with reverse free flow check valve.
  • Smallest high-pressure flow control valve on the market.
  • Prevent component cam damage from unexpected or accidental surges in flow rate.
  • Adjusting screw is positively retained and will not come out under pressure.
  • Integral reverse free flow check valve for use with single or double acting clamps.
  • Flow control requires the use of manifold mount ports.

EMO Preview: High Capacity + Part Present Sensing Work Supports

 

 

 

Vektek at EMO 2019
Hall 5 Booth G78

New for EMO Vektek introduces Work Supports with up to 3X capacity at 350 Bar!

Plungers stay retracted during part loading. Hydraulic pressure advances the plunger exerting only spring force as it makes contact with the part. Hydraulic pressure then automatically sequences, “freezing” the plunger, to properly support the part.

  • Available in 8kN (M26) or 15.5kN (M35) capacity.
  • Order with base or cartridge only.
  • Ventless configuration and built in wipers protect the plunger movement from chips and debris.
  • Base is compatible with Vektek’s In The Port Flow Control & In The Port Sequence Valves.
  • Uses Vektek’s BHC technology to guard against corrosion.
  • O-Ring face seal design makes machining cavities easier.

Standard G Series porting and alternate O-Ring manifold face seal is located in the base of the support flange for bolt down installation. Cartridge mount, 3 or 4 bolt flange options available.

 

High Capacity Part Present Sensing Work Supports!

Confirm part is present and contacted even on as-cast surfaces!

Plungers stay retracted during part loading while air flow travels through the work support. Hydraulic pressure advances the plunger exerting only spring force as it makes contact with the part. This closes the integral air valve to indicate part is present and contacted. Hydraulic pressure then automatically sequences, “freezing” the plunger.

  • All the details stated above – plus…
  • Once support is locked, air sensing positively confirms both contact and part present.
  • Use Vektek’s Air Sensing Control Kit 45-0824-00 for easy setup.
  •  Max air operating pressure is 1 bar.

MAPAL: Milling Fibre-Reinforced Plastics

The High Requirements of Milling Fibre-Reinforced Plastics

 

 

 

 

 

 

 

The Machining Task

The machining of CFRPs (carbon fibre reinforced plastics) places high requirements on the tools used, their geometries and coatings. Due to the abrasiveness of carbon fibres in relation to the cutting material, standard tools very rapidly become blunt and the end of tool life is reached after only a few parts. To be able to cut carbon fibres that are laid in a matrix form, increased performance at the cutting edge is required. This statement applies above all if the carbon fibre content is more than 60 %. On milling the peripheral contour on a 21 mm thick structural part for a sports car, the customer had a clear requirement to double the tool life from the previous 10 parts to 20.

The Challenge

The challenge is to keep the milling tool sharp and therefore to prevent delamination at the part edges produced. In this way expensive, manual re-work is saved. At the same time, the issue is to reduce the machining time and to realise long tool lives.

 

 

 

 

 

 

The Mapal Solution

The eight cutting edge, diamond coated solid carbide end milling cutter OptiMill-Composite-Speed has a high performance geometry with a serration. This serration makes possible improved chip removal and therefore an extremely high volume of chips in one machining step. As a result the machining is undertaken using only one tool in one step and the roughing step necessary previously is saved. With twice the feed and three times the material removal rate the tool life is increased fourfold and the quality requirements in relation to surface roughness reliably achieved. As a result the customer’s expectation in relation to tool life were exceeded by a further 20 parts.

The MAPAL Effect

  • Four times the tool life reduces the tool costs
  • Doubled feed halves the machining time
  • Only 1 machining step
