etc.
WTFTOOL manufacturer processing customized cemented carbide
non-standard solid carbide deep hole drills - Design &
production according to the drawing and sample!
Â
Deep-hole drills refer to the drills specially used for processing
deep holes. Changzhou WTFTOOL is a professional manufacturer of
carbide non-standard tungsten carbide deep-hole drills. In
mechanical processing, the ratio of hole depth to hole diameter is
usually greater than *0, which is called deep hole. The ratio of
hole diameter of non-standard deep hole drills produced by WTFTOOL
can reach more than *0XD. It is difficult for deep-hole drills to
dissipate heat and remove chips during drilling. For this reason,
WTFTOOLÂ engineers have designed non-standard solid carbide
deep-hole drills which are easy to remove chips and have good heat
dissipation by using many years of tool processing experience.
Because of the slenderness of deep-hole drills, shaking and bending
should be avoided in the processing and production (hard carbide
has strong hardness but weak rigidity). Pressure cooling system is
generally used to solve the cooling and chip removal
problems.
Â
Processing characteristics of non-standard solid carbide deep hole
drills:
1. The characteristics of chip removal and heat dissipation should
be taken into account when drilling bit with longer blade length,
and attention should be paid to feed and rotational speed.
2. Because the edge is in the deep hole, it is impossible to
observe the situation in the hole during processing.
Â
Graded feed for deep hole drilling can be considered
When drilling deep holes with non-standard tungsten carbide deep
hole drills, the cutter quits quickly after a period of feed, the
workpiece removes chips, and then quickly approaches the processing
part and continues to work, so many times to and fro until the
required hole depth is processed, which is called graded
feed.
Deep-hole drills can be divided into ordinary deep-hole drills and
inner-cooled deep-hole drills according to the cooling method.
Internal cooling is to prevent excessive temperature of the contact
area of the cutting edge from cooling with coolant in order to
prevent the occurrence of bit fracture.
Â
Drill Bit breaking
1. Chip breaking is not good, chips can not be discharged: changing
the size of chip breaking groove to avoid excessive length and
shallowness; timely finding and replacing the chipping edge;
increasing the pressure and flow rate of cutting fluid; adopting
workpieces with uniform material structure.
2. Excessive, small or uneven feed: appropriate cutting
parameters.
3. Excessive wear of drill bit: periodically replace the drill bit
to avoid excessive wear.
4. Incorrect cutting fluid: Choose suitable cutting fluid and
improve filtration.

Integral carbide deep-hole drills/non-standard solid carbide
deep-hole drills are generally used in automotive crankshaft,
engine and tubesheet industries. Applicable workpieces are:
structural steel, alloy steel, stainless steel and other common
materials processing.
