Grinding Machines for the Firearm and Ammunition Industry

Rollomatic, a leading machine tool manufacturer based in Le Landeron, Switzerland, maintains its global leadership position in the field of multi-axis CNC grinding by presenting two grinding machines which have specific capabilities for grinding a variety of gun-related tooling and components. Rollomatic has worked with many leading manufacturers in the firearm and ammuni•on industries to develop and fine•tune grinding processes for the following fields: 

Manufacturing parts for the weapons industry: 

  • Production grinding of firing pins 
  • Prototyping cylindrical parts for guns 


Rifle chamber manufacturing and reconditoning: 

  • Chamber reamers in tungsten carbide for rifle chamber cutting 

Cold forging in radial forging machines: 

  • Forging mandrels in high-cobalt tungsten carbide
  • Forging hammer dies (in sets of 2 and 4) in tungsten carbide 

Punches for ammuni•on tooling manufacturing: 

  • Solid carbide draw punches for bullet casing manufacturing 

GrindSmart® 630XW 6-axis tool grinding machine:

  • With 6-station wheel and nozzle changer
  • Automatic tool loader/unloader
  • Linear motion technology for improved surface finish
  • Universal workhead with high-speed capability to combine high-accuracy cylindrical grinding and geometry grinding
  • Large variety of workholding and tool holding solutions including custom-made fixtures

ShapeSmart® NP50 5-axis pinch/peel cylindrical grinding machine: 

  • Automatic 3-axis tool loader/unloader
  • Pinch/peel grinding process in combina•on with V•block part support and with simultaneous grinding of roughing and finishing passes 
  • Multi-pass grinding for efficient heavy stock removal 
  • Amazingly large diameter range from 0.0008” to 1” 
  • Patented non-round pinch/peel grinding for all non-round shapes such as square, rectangle, oval, corner radius and any other non-round profile
  •  Onboard diameter gauge included 
     

Related Glossary Terms

  • computer numerical control ( CNC)

    computer numerical control ( CNC)

    Microprocessor-based controller dedicated to a machine tool that permits the creation or modification of parts. Programmed numerical control activates the machine’s servos and spindle drives and controls the various machining operations. See DNC, direct numerical control; NC, numerical control.

  • cylindrical grinding

    cylindrical grinding

    Grinding operation in which the workpiece is rotated around a fixed axis while the grinding wheel is fed into the outside surface in controlled relation to the axis of rotation. The workpiece is usually cylindrical, but it may be tapered or curvilinear in profile. See centerless grinding; grinding.

  • grinding

    grinding

    Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.

  • tungsten carbide ( WC)

    tungsten carbide ( WC)

    Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.

The GrindSmart 660XW is a 6-axis tool and peel grinding machine allows the user to utilize cost-effective and advanced  lean manufacturing principles; termed as “Ultra-Lean Grinding Process.” The machine includes a 6•position wheel changer and linear motors on all axes. It features a traveling high Read More
As the name suggests, cutting taps produce threads by progressively cutting away the space between threads into which the fastener's external threads will fit. Forming taps, by contrast, remove no material. Instead, they move or displace material inside the hole to build up the threads and dig Read More
This model is part of the GrindSmart® series of tool & cutter grinding machines with an axis configuration that incorporate 6 fully interpolated axes (3 rotary and 3 linear) and is unique in this industry. The machine also incorporates linear axis drive technology. 
Both grinding spindles are “synchronous direct‐drive spindles” with 19 hp peak each. The most important feature of a synchro­nous motor is that it provides constant speed during its operation and that the torque curve is highly efficient, as per above graph.
