  • HPC fullslot

  • HPC roughing   

  • HSC side roughing (maximum speed) 

  • HSC side finishing

  • Trochoidal milling

  • Milling in non-rigid conditions (MTC)

Conventional or climb milling?

Only climb milling is allowed with Swissceramill

  • just has to be milled like that

  • This is the only way that Swissceramill works

Is cooling important?

We generally recommend always milling with coolant.

 

  1. Work with internal cooling and external cooling

  2. Work with internal cooling

  3. Work with external cooling

We recommend a high coolant pressure, preferably up to 70 bar.

If you want to work with a lower cooling pressure, you have to keep the speed and the feed per number (fz) low at the beginning

Which machines are suitable  themselves  preferably?

Swissceramilll can be used on all CNC machines.

There are no restrictions on size or speed.

Swissceramill can be used for both high-performance milling and high-speed milling.

 

Regardless of the machine performance, Swissceramill can always be used to achieve the desired results.

At low speeds, the potential of the tool is not used, but it is much better than with carbide tools in terms of surface quality and dimensional accuracy.

Swissceramill can be used on all CNC machines.

  • Machines with rpm 6`000 and higher

  • Machines with speeds of up to 100,000 rpm

The most common machines for high-performance machining (HPC) are machines with speeds of 6,000 - 30,000 rpm

  • Try to mill with a medium feed rate and ae = 1xd and ap = 1.5xd (full slot milling)

  • Finishing possible with a medium feed rate ae = 0.05xd and ap = 2xd

Most of the common high-speed milling machines (high-speed cutting) are machines with a speed of 30,000 - 100,000

  • Try to mill a full slot with a high feed rate and ae = 0.05-0.2xd and ap = 0.1-0.5xd

  • Finishing with feed rate fz = 0.02-0-06 ae = 0.02xd and ap = 2xd possible

For which industries  is Swissceramill well suited?

Swissceramill is very well recommended in the following industries and applications.

  • Contract manufacturing of medium and large series. 

  • Watch industry

  • Jewelry industry

  • Manufacture of impellers

  • Manufacture of machine components

  • Aircraft industry

  • Automotive industry

  • Machining of cast parts

  • Medical parts made from PEEK and other plastics

  • Manufacture of car rims

  • Manufacturing  from  Copper and graphite electrodes

  • Production of series parts

What is the right procedure to start with Swissceramill?

First step

  • Select the milling strategy with which you want to mill

  • Look at our cutting data recommendation at the beginning

  • Use our recommendation to get started with programming

  • Start a cad / cam simulation

  • Check the simulation for possible collisions or other errors.

  • Start of milling with 70-80% of the programmed feed

  • Increase the feed rate to 100% or higher.

 

  • Different materials require different cutting parameters

  • If the tensile stress of a material is high, the values (vc and fz) should be selected lower.

 

  • Use white ceramic only with high pressure coolant

  • Green ceramic with coolant preferred, but not necessary
