Heavy-duty CNC Tungsten Carbide Roll Grinding Machine

TCG400; CNC TC Roll Grinding Machine

CNC Tungsten Carbide Roll Grinding Machine

Model: TCG-400

l  Features:

  1. Direct Grinding Technology by Formed Diamond Grinding Wheel.

  2.  High Efficiency for groove (pass) grinding on TC ring.

    Just take about 45 minutes to finish the one groove’s grinding from plain TC roll (Rebar size: 10mm). If redressing (renew) old groove on TC ring, it just take about 20 minutes/groove for grinding.

  3.  Specialized Software for TC ring’s surface and groove grinding. Choose the  machining mode, it will work automatically.

  4. CNC program can remember the diamond grinding wheel’s position by itself during machining.

  5. High Rigidity: All main parts: Bed, headstock, bed are castings (HT250/300). Not welded steel plates. The  total weight of machine is about 4500 kg. 

  6.  Built with ‘SIEMENS 808D Advance‘ CNC system.

  7. TC ring holder Device: Self-centering elastic expansion sleeve for TC ring’s mounting or release by hydraulic. The CNC control panel give the order to hydraulic for pulling or pushing the draw bar to make the elastic expansion sleeve move on tapper mandrel for clamping or release to TC ring. Easy & Comfortable Mounting or Release for TC ring on machine. (Included with machine)

  9. Spindle using SKF or FAG Double row short cylindrical bearings.

  10.  ABB brand, 18.5 kw motor for grinding wheel support with belt drive to achieve strong grinding power. If grinding wheel diameter 250mm, its linear speed will be around 25m/s.

  11. Adopting none-contact Labyrinth Seal for spindle. Protect the spindle for long working life.

  12.  Forming Diamond Grinding Wheel can be sharpened by the partner machine (Profile Dressing Machine for Diamond Grinding Wheel, Model: DCS-003A. Detail see attached brochure.)

  13. Pass Gauge (pattarn plate) (1 set) will be supplied together with your machine for pass checking on TC ring. The pass pattarn plates are made as per customer provided TC ring’s pass drawings.

l  Consumer Items (Diamond Grinding Wheel):

Considering smooth commissioning & start up, please order some typical diamond grinding wheels with your machine. All these diamond grinding wheels will be ground well as per your pass drawing on TC ring.

If the grinding wheel wear out, you can resharpen it by ‘Profile Dressing Machine, model: DCS-003A’. Our engineer will train your operator about the redressing of old diamond grinding wheel. It will help you to save consumer costs.
