Tooling Grinder

Mainly sharpen punch and die in punch press tooling,Maxima grinding diameter 150mm.Rotary worktable can adjust 0—15 degree that can grind rooftop/shear punch with good symmetry.Machine desiged with spindle coolant system,which prevent burning tools and improve life. NCT punch press machine is an automatic and efficient sheet metal fabrication equipment, Tip of punch and die easily become worn because of high speed punching speed,especially for nibbling punch.If the worn tooling continue to work,it affect quality of sheet metal,and shorten tooling life.According manual of punching technology, operator should sharpen tooling on time and frequently.The punch and die is worn when sheet metal has big bur or more noise voice of punching.On cutting edge, there about radius about 0.1mm,then should regrind

Grinding method is very important,please Comply with below regulations

• When grinding,punch tightened in holder, The amount of rough grinding is 0.01mm. The amount of precision grinding is about 0.005mm. Repeat grinding till it's sharp. Max grinding amount is 0.1mm – 0.3mm
• Sugesst to use open,coarse,soft bond wheel , the hardness D~J,grit size about 46~60, best wheel is high speed grinding wheel.
• The tool must be flooded with coolant while grinding, it prevent cracking and annealing because of high temperature
• Wheel go down, Feed volume 0.005~ 0.01mm. Base horizontal feed volume 0.13~ 0.25mm. horizontal feed speed 2.5~3.8m/min
• After grinding,grind cutting edge to remove bur. Get radius 0.03~0.05mm
• Punch should remove magnetic and spray with lubricant to prevent rusty

Features

• Tool setting automatically,Autofeed Most important features(automatically tool setting): Automatic wheel run down, it will automatically induce the presence of tooling, when the wheel touches the tooling, the cooling system starts to work, NC starts clearing, grinding movement begins from this point to ensure the accuracy of the amount of grinding. Grinding wheel and the rotation is always in contact with the punch or die, Grinding wheel  control feed,keep continuous contact between the wheel and die ,keep pressure constant, thereby ensuring a high grinding quality and efficiency.
• Fully weldedframe----Ensurethe stability of machine body
• Doublelinear guide----Ensure the stability of the motor movement
• work table by precise grinding----Ensure that the machine table face perpendicularity, concentricity.
• Precisionguide screw----Ensurethe accuracy ofgrindingfeed
• Cooling systemthrough the spindle----Directly cool internal grinding head to prevent softening
• Japan'sMitsubishiPLC controller----CNC controllersafe, stable and reliable
• Servomotor----Reliable, sustainable and efficient.
• Contactor unit by Schneider made------Famous brand unit,`more stable,durable.
• Stainless steel----shellCorrosion resistance, never rusty
• Boronizing Wheel----Durable, longer grinding life
• Intelligent,Automatic----Easy to operate.

Structure

Assemble by the grinding wheelframe, grinding depthadjusting mechanism,feed mechanism, rack, three-jawchuckfrom thecoreset, the motor and coolingsystem components

Rotarystage with athree-jawchuck, which meetall kinds of grinding forpunch, die,stripper plate.

Worktable Quickly tilt 0 - 15degrees, suitable forgrindingedgeofthe roofstructureof thetooling like rooftop,whisper.

It isproduced byspecial jaw chuck with Counterclockwise and cloclwise, grindingdifferent specificationsof the punch and dieis very convenient

can be accurately rotated 180 degrees to ensure that punch with rooftop type is completely symmetrical, avoiding partial load generated when punching
