Wood milling cutters in the milling process

Wood milling cutters are used for milling, having one or more rotary knife cutter teeth. Each tooth in turn intermittently cut margin of the workpiece at work. Cutters mainly used for processing flat, level, trench on milling, shaping the surface of the workpiece and the cutting and so on. For the horizontal milling machining plane. Distributed on the milling cutter circumference divided by tooth spur and helical gear two. Divided by the number of teeth of two coarse teeth and fine. Helical teeth less coarse tooth cutter, cutter high intensity, large chip space for roughing; fine-tooth cutter suitable for finishing. And the cutter body are integrally formed teeth. Tooth carbide or other wear-resistant tool material and brazed on the cutter body. Drilling Tools  clamping cutter approach fastened to the blade. This interchangeable cutter heads can be whole tool material, the tool can also be a bit of welding materials. Head mounted on the cutter blade sharpening cbn grinding wheel style called the body; heads on separate sharpening jig grinding style known as in vitro. When optimizing the effect of the 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 cutting blades, each of the cutting a cutting edge can not simultaneously cutting power required and the number of participating in the relevant cutting edge cutting, the chip formation process, the processing load, and the results of the cutting edge, the cutter relative to the workpiece plays an important role.

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 cutters introduction and application

Wood milling cutters, for milling, with a rotary cutter of one or more teeth. Each tooth in turn intermittently cut margin of the workpiece at work. Cutters mainly used for processing flat, level, trench on milling, shaping the surface of the workpiece and the cutting and so on. When optimizing the effect of the milling, wood milling cutters 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 cutting blades, each of the cutting a cutting edge can not simultaneously cutting power required and to attend the cutting edge of cutting the number of relevant, on chip formation,flap abrasive cutting wheel edge loading and processing the results, the position of the workpiece relative to the cutter plays an important role. When face milling, with a wood milling cutters width of approximately larger than the milling cutter and workpiece location close to the center, then the chip thickness changed little. When the Leads wood milling cutters thickness of chip thickness ratio slightly thinner at the center of some of the cutting. End mill with the top surface machining wood milling Abrasive Cutting Wheels, is the disc type, only cutting edge end face; end mill is designed to milling a workpiece plane, very flat end mill milling efficiency.When face milling, cutting width with a ratio of about larger cutter and the wood milling cutters location close to the center of the workpiece, so little change in chip thickness. When the Leads wood milling cutters 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 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.

  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.

Under ideal conditions, cutter diameter than the width of the workpiece to be large, milling axis and workpiece should always leave some little distance from the centerline. When the tool is being placed on the machining center, easy to produce glitches. Cutting edge when entering and exiting the cutting direction of the flap abrasive cutting wheels radial cutting force will continue to change, spindle vibration and may damage the surface of wood milling cutter the blade may shatter and processing will be very rough, slightly off-center milling, cutting force direction will no longer fluctuate - cutter will obtain a pre-load. We can put the center in the center of the road Drilling Tools likened to driving. Every time when the cutter blade into the cut, the cutting edge must withstand impact loads, load cross-section depends on the chip, workpiece material and cutting type. When the Leads, whether correct occlusion between the cutting edge and the workpiece is an important direction.
