The HS-CF is the ideal machine for the fully automatic processing of cylindrical and conical steel and iron samples. The machine has been designed to prepare samples for OES and CNS analysis.

Processing of a wide variety of samples types
The HS-CF can be either operated in the laboratory or production site. A wide variety of sample shapes can be processed including round and angular samples as well as samples with and without mounting pin. Moreover, it is possible to process other sample shapes by arrangement. The only prerequisite here is that the sample must have two parallel lateral surfaces. These are required in order to fix it firmly in the clamping device. The HS-CF can handle all types of cast steel with different ranges of hardness. The individual work processes are executed completely automatic according to the program selected:
  • Pre-selection of the milling head to suit the quality of the sample
  • Single and multiple milling of samples with infinitely adjustable feed rate, in-feed and rotational speed
  • Cooling of samples
  • Cutting of samples with one or two separating cuts: One possibility is to cut off a sample for the OES. The other possibility involves the extraction of a slice of varying thickness between 4 to6 mm. At a later stage, it is possible to punch samples (e.g. with the HUST) from this slice for the CNS analysis.

    Designed for manual and automatic operation
    The input of samples can either be manual by the operator or automatic by a robot or via conveyor belts. Alternatively, a variety of input magazines are also available. These magazines allow input of samples to be cut before milling or which do not require any cutting. In automatic mode, the samples can be fed directly into the machine by the robot. The cut slice, as well as the milled sample, are released automatically from the machine and can be further processed. The cut slice can, for example, be transferred automatically to the HUST in order to punch samples for CNS analysis.

    Optimal Milling
    Two independently operated precision milling spindles can be fitted with milling cutters for various material grades. Thus there is no need to exchange tools when changing from steel to iron and vice versa. The extremely sturdy spindle bearings permit safe, sustained processing of even the hardest material grades. Tool change is quick and easy – without any special tools being required. Milling of samples takes place from below. This excludes the necessity for measuring the sample height as well as other additional handling stages. Thus optimum processing times are guaranteed. Special milling tools and different cutting materials, optimally adapted to suit all material grades, can be used. Tool life times are monitored. Tool changes and maintenance intervals are displayed on the machine control panel.

    Optimal Cutting
    The intelligent servomotor torque control guarantees particularly effective material cutting. The sturdy cutting disc drive in conjunction with the HERZOG high capacity cutting disc guarantees top speed with maximum surface quality.

    Simple Control
    All relevant parameters for cutting, milling, de-burring, cooling etc. can be easily adjusted via the PLC or (in automatic mode) by the PrepMaster. The parameters are included in up to 16 programs which can be selected according to the specific sample type. Intelligent menu navigation and clear graphical presentation support the operator in selecting the correct parameters.

    Simple Operation and Maintenance
    The well accessible front and back of the machine makes maintenance and cleaning particularly easy. The waste collection containers for residual cut-offs and chips as well as local exhaust ventilation are easy to access and empty. The machine is noise-insulated and especially designed for low-noise operation. It is therefore suitable for laboratory use.
