wood milling cutters about cutter common problem Mills vibration

  Since the deposit is a small gap between the cutter and the tool holder, so the process is likely to occur in the tool vibration scene. Vibration causes uneven circumferential edge cutter knife to eat the amount, and the expansion ratio of the original cut value increases, the impact of the machining accuracy and tool life. But machined groove width is too small, you can purposefully make the tool vibration, expansion through increased cutting width to obtain the required amount, but the maximum amplitude in this case should cutter is 0.02mm or less, or not Drilling Tools stable. Vibration normal processing cutter smaller the better.
When the tool vibration, you should consider lowering the cutting speed and feed rate, as both are still being reduced by 40% after a large vibration, you should consider reducing the amount of cut.
Such as processing fragmentary resonance occurs, the reason may be the core drilling bit speed is too large, the feed rate is precisely the small, fragmented tool just is not enough, not enough workpiece clamping force and shape of the workpiece or workpiece clamping essentials due to other factors, you should accept mediation cutting parameters, tool piecemeal add stiffness, improve feed rate and other measures.

wood drill bits workpiece edge line coincident

When the cutter axis and workpiece edge line coincident or close to the edge line of the workpiece, the situation will be very serious.
  Check the machine's power and rigidity to ensure the desired cutter diameter can be used on the machine.
  Spindle overhang on the shortest possible tool to reduce the impact of the position of the flap abrasive cutting wheels and workpiece axis shock loads.
  Suitable for the process using the correct pitch milling, to ensure there is not much in the cutting insert and the workpiece while vibration caused by engagement, on the other hand, when the narrow core drill bit or milling a workpiece cavity to ensure there is sufficient blade and workpiece engagement.
  To ensure that the use of the feed per insert, so that when the chip is thick enough to obtain the correct cutting effect, thereby reducing tool wear. Using positive geometry indexable inserts to obtain a smooth cutting performance and lowest power.
  Selection of suitable width of the cutter diameter workpieces.
  Choose the correct primary angle.
  Correct placement cutter.
  Cutting fluid used only when necessary.
 Follow the rules of maintenance and repair tool and monitoring tool wear.

wood milling cutter Introduction and purpose cutter

When optimizing the effect of the milling,  wood milling cutter blade is another important factor, if at any time while participating in the milling cutting insert more than one number is an advantage, but the drawback is that many also participate in the number of wood milling cutter blades, each of the cutting a cutting edge can not simultaneously cutting power required and to attend the cutting edge of flap abrasive cutting wheel the number of relevant, on chip formation, cutting edge loading and processing the results, the position of the workpiece relative to the cutter plays an important role. When face milling, cutting width with a ratio of about 30% larger cutter and the  wood milling cutter location close to the center of the workpiece, so little change in chip thickness. When the Leads Diamond Cutting Blades thickness of chip thickness ratio slightly thinner at the center of some of the cutting. Rough milling, removal of a large number of blanks, or the outline of a small area of ​​the horizontal plane finishing. For surface finishing and semi-finishing; small ball end mill can be as small chamfered surface finishing as well as irregular contours steep face / straight wall. Chamfer cutter with a flat head, do rough milling to remove a lot of blanks, but also fine milling of fine smooth surface (relative to the steep surface) small chamfer.

wood milling cutters use of the milling cutter clamping

Most accepted milling machining center with spring clip suits the way, in the form of the use of the cantilever. Milling process is sometimes possible to gradually extend from the milling tool holder, so complete? Lost, so that the workpiece scrapped scene, its reason for existence is generally due between the toolholder shank outer diameter of the hole and core drilling bit film formation due to insufficient clamping force. Generally when coated with anti-rust oil milling factory, if you use a non-water-soluble cutting oil when cutting, when the toolholder bore film will be attached to a layer of mist, selling holder and the holder on the film are being kept, the toolholder is difficult to firmly grip handle, being processed in the milling on the loose fall. So before being cutter fixture, should first milling toolholder shank and bore clean with a cleaning solution to clean, dry and then be clamped.
When larger diameter Drilling Tools , even shank and tool holder are clean, or might occur? Lose knife accident, then the gap should be used with a flattened side lock holder and the corresponding way.
Another title that may arise after the cutter is clamped milling machining toolholder being broken at the port, its origins are generally due to the use of the tool holder light for too long, the toolholder taper port portion is worn due, and you should replace with a new knife folder.

wood milling cutter wood drill bits

  Drill installation Drill slowly lifting the box, the four legs of the box corresponding drill holes into four turntable rig, according to the choice of the appropriate size drill core drill box, lifting the drill core box drill box into the body and then to groove and drill flap abrasive cutting wheels core box corresponding convex tip installed, will drill into the box drill, drill that card on the turntable heart. Then turn on the drill spin coupling nut drill pipe.  drill demolition Lifting drill pipe, drill cartridge requirements connected with the turntable, lifting the drill pipe and drill bit slow groove of the drill core box corresponding convex tip, drill drill stuck in the box, turn receded drill, drill.
   Use  drill should be packed in a special packing boxes, to avoid vibration collide. When  use, remove the drill bit from packing boxes to be loaded into the spindle collet that header or automatic replacement Metal Cutting Saw Blades tool library. Then run back into packing boxes. drill diameter measurement tools to use microscopes and other non-contact measurement equipment, to avoid the cutting edge in contact with the mechanical gauges were bruised.  some CNC drilling using some CNC drilling positioning ring retaining ring is not used, such as the use of its fixed ring during installation Depth positioning must be accurate, as it does not use retaining ring fitted to the drill spindle elongation to adjust consistency, multi-spindle drilling machine to pay attention to this point, to make the drilling depth of each spindle to be consistent. If it is not possible to make the drill bit to drill the table or unable to drill through the circuit board caused scrapped.

wood milling cutter The basis for selection of cutter

Selection is based on a cutter, was cutting wood Drilling Tools  nature of the material objects are wood and wood composites. Wood can be divided into soft wood, hard wood timber and modification, etc.; wood composite materials include plywood, laminated veneer lumber, particleboard, OSB, waferboard, gypsum particleboard, cement particle board, hardboard, medium density fiberboard, high density fiberboard, block board, glued timber and so on. Some wood or wood composite workpieces to go through one-sided or double-sided decorative veneer processing. Second, the core drilling bits direction of the cutting wood, the wood fibers according to the direction opposite the cutting edge into the vertical timber, horizontal, side to side direction and the longitudinal, vertical and horizontal direction and transverse to the core drills bit end. Third, the tool rotation direction and the feed direction according to the rotation direction and wood workpiece axis machine tool feed direction, determine the tilt direction of the tool cutting edge. Fourth, the stability of the tool and the workpiece in the stability of the cutting tool and the workpiece in a machining process includes several aspects, refers to the stability of the workpiece in machining workpieces of wood feed smoothly without the risk of beating. Measures taken to strengthen the stability of the workpiece mainly lower center of gravity and increase the contact area of ​​the workpiece. Fifth, the machined surface quality of the workpiece surface quality requirements, including wood surface roughness, geometry and shape position accuracy.
