CNC Milling Centers Mazak AJV3560 / Mazak VTC-200C
(Precision milling up to 30”W x 55”L)
These double-column vertical machining centers are among the highest precision machining centers made by Mazak. Built for rigid accuracy, these machining centers utilize the revolutionary Mazatrol CAM M-2 to ensure high speed and high performance for all your milling requirements.
CNC Turning Centers - Mazak Quick Turn 20N / Mazak M5N
(Precision turning up to 13”D x 10’L)
These Mazak CNC Lathes can economically machine a single prototype part or full production runs. These computer-operated lathes boast a wide range tooling system and provide fast, accurate machining every time.
(Surface grinding up to 36” and 42” diameters)
For a precision ground surface, we use Blanchard grinding, well known for the trademark “cross-hatched” surface finish pattern resulting from a wheel-turning motion and the rotational movement of the work piece. Blanchard grinding utilizes more horsepower than other grinding processes and is also quicker, because multiple pieces can go through the Blanchard grinding process at once.
(Surface planing up to 2’H x 5’W x 20’L)
This type of surface planer uses a single-point cutting tool to create a linear tool path. It is similar to a shaper but larger, with the work piece moving in linear motion beneath the cutter. The cut is similar to a lathe, although it is linear, not helical.
(Broaching from ½” to 2” key width)
Broaching is a process using a toothed tool, called a broach, to remove material and cut specific shapes into your metal. We use vertical broaching, in which the broach is run along the work piece to create the cut. Broaches are similar in shape to a saw, except the teeth get larger toward the end of the tool. Broaching is used to create precision shapes, on surfaces such as keyways, holes and splines.
