Universal Tool Grinding Machine WS 1

The "universal genius". The ideal machine for small and medium workshop. Simple operation, accuracy and flexibility make the WS 1 for "Swiss army knife" in tool grinding.

Universal Tool Grinding Machine UWS 4

The "big sister" of the WS 1 greater flexibility
and a variety of accessories. It has all the advantages of WS 1, but with larger stroke ranges and a swivel work table.

Universal Tool Grinding Machine UW1 A

SAACKE universal manual tool grinding machines are ideal for economic grinding and edge refurbishment of
Individual tools and small series of HSS and Carbide for metal and woodworking industries.

More Information
Universal Tool Grinding Machine UW 11

The model UW II is also based on the SAACKE and is on the forefront of conventional grinding technique. The modern and functional design and the sturdy construction meet the highest standards in terms of accuracy and performance.

More Information
Universal Tool Grinding Machine AWS 10

The AWS 10 combines the compact design of conventional WS 1 with the latest drive technology. The table movement can be regulated either manually or continuously by frequency controlled electric motor. Optional for the AWS 10 is a digital display for the longitudinal, transverse and vertical axis.

More Information
Universal Tool Grinding Machine AWS 20

Machine body and structure are identical to the conventional UWS 4 but with switchable motor-driven table stroke. As with the smaller AWS 10 also digital displays (for max. 3 axis) are optional.

More Information
Universal Tool Grinding Machine AWS 30

The AWS 30 is identical to UWII. The table drive is hydraulic.

DRILL GRINDING
CHRISTEN 1-32 SPECIFICATION
With capacity from 1 mm up to 32 mm the 1-32 machine offers unrivalled versatility in being able to produce standard radial relief points, 4-facet and split point geometries as well as being able to web thin in various forms. Both HSS and Carbide drills can be sharpened and the machine will also grind the lead on various types of taps. Step drills with or without pilot relief can be ground, the former requiring additional equipment which allows the spiral to be generated on the relieving operation. Countersink tools, spade drills and other special tools can all be ground on this machine. Grinding range 1-32mm
0.040-1.25"
Infinitely variable clamping range
Radial relief
Double angle points
4-facet and split points

  FSW-155 SPECIFICATION
The FSW-155 is an infinitely variable spiral grinding unit that allows any spiral, left or right-hand to be set on the backlash free system that caters for all angles of spiral from 0-∞. The unit will mount onto all popular makes of cutter grinder and features finger free grinding of all sizes of cutter and is especially good for grinding ripper cutters where grinding from a ginger gives very poor results. The body clearance of cutters can be ground very quickly with the clearance angles being easily and accurately set. A cutter ground on this system will match a CNC ground tool for accuracy.

Spiral angle R.H./L.H. 0-∞

Collet capacity - ISO 40

Grinding length - 155mm

Supply - Single phase 240V

 
The NCW range of CNC controlled grinding fixtures feature single axis indexing heads (NCW-100), two axis grinding fixtures (NCW-155) and three axis cutter grinding (NCW-300). All the options feature the same highly acurate, back-lash free indexing head capable of up to 999 divisions. The two and three axis units have high precision ball screws for the linear axis ensuring excellent spiral generation or straight grinding with excellent repeatability. Software for all popular grinding requirements are included in the control package. Options of stepping motor or servodrives are available on all the units and a choice of control units is available to suit particular applications. The units will mount on any of the popular tool and cutter grinders and give automatic grinding, allowing the operator to control two or more machines dependant on application

SAACKE
Saacke have been producing cutting tools for over 100 years. The machine tool section was formed to produce machine tools meeting their most demanding applications which were simply not available elsewhere. Their range of Hob Grinding and Universal Tool & Cutter Grinding machines meet the high standards that todays markets demand.
The UW 1 C offers the accuracy of CNC grinding with the speed of setting of a manual tool & cutter grinder in a unique package. The grinding head rise and fall is motor driven whilst the two axis CNC will generate accurate spirals for parallel and tapered tools. A wide range of software covers all conventional applications with special software being offered for high performance drill point geometries.
 

CNC Tool and Cutter Grinding Machine with 5 CNC axes

The UW 1 E machine offers the latest in software development with the high standards of precision associated with heavy stable construction and large dimensional guiding systems but with clever design engineering is condensed into a compact machine construction.The machine offers the benefits of digital control and axis drives, a workhead directly driven for cylindrical grinding and a large grinding spindle with wheel packages at both ends. This, coupled with the automatic handling system, probing system and user friendly software for a complete range of cutting tools for the metal and woodworking industries, results in a machine high on specification but low on price. Touch screen technology as well as 3-D simulation are also available.
